Answer:
g is a geometric sequence.
g(1) = 6
g(n) = g(n-1)*2
Step-by-step explanation:
A geometric sequence is one in which each next term is found by multiplying the previous term by a constant number.
In our case the rabbit population doubles each month, therefore we are multiplying the population of the previous month by 2 to get the population of the next month. Thus g(n) is a geometric sequence.
The sequence described is a geometric sequence with a ratio of doubling each month. The recursive formula for the sequence is g(1) = 6 and g(n) = 2*g(n-1).
Explanation:The sequence described is a geometric sequence. In a geometric sequence, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the ratio. In this case, that ratio is 2 because the rabbit population doubles every month.
When providing the recursive formula for the function g(n), the first term, g(1), would be 6, as that is the number of rabbits Fenyang started with. For any other term in the sequence, g(n), it would be twice the previous term, g(n-1). So, the complete recursive formula for the sequence would be:

Answer:
I think D.
Step-by-step explanation
Answer:
Part(B) is the correct answer
Step-by-step explanation:
Given functions are
f(x) = [tex]4x^3+5[/tex] and g(x) = [tex]\sqrt[3]{x-5/4}[/tex]
So both are inverse of each other
Since Definition of inverse function is
If a function f(x) is mapping from x to y , then the inverse function of f(x) maps
y back to x.
Solution
suppose
y = f(x)
y = [tex]4x^3+5[/tex]
in order to find inverse of f(x)
interchange the variables x and y
x = [tex]4y^3+5[/tex]
Now solve for y
Subtract 5 from both sides we get
[tex]4y^3[/tex] = x-5
Divide both sides by 4 we get
[tex]y^3[/tex] = (x-5)/4
[tex]y = \sqrt[3]{x-5/4}[/tex]
so this is the inverse of the f(x) and also from this we see that is [tex]g(x) = \sqrt[3]{x-5/4}[/tex]

school spirit club wants to raise money by selling t-shirts. one local company charges a fixed fee of $75 for creating the design and $5 for each shirt that they print. Write an equation describing the spirit club's income if they sell each t-shirt for $8
Answer:
The profit = $(3x - 75) where x = number of t-shirts sold
Step-by-step explanation:
School spirit club wants to raise money by selling t-shirts. one local company charges a fixed fee of $75 for creating the design and $5 for each shirt that they print.
We have to find the club's income if they sell each t-shirt for $8.
Let the number of t-shirts that the club sell be equal to x.
So the cost of making x t-shirts = 75 + 5x
If the club sells x t-shirts , then the money they earn = 8x
Profit = selling price - cost price
= 8x - (75 + 5x)
= $(3x - 75)
The club also needs to sell at least 25 t-shirts to make a profit and from then on makes a profit of $3 on each t-shirt they sell.

$11.62
Answer:8-oz jar
First, we have to find out what is the unit rate of the 2-oz jar. $1.50÷2 is $.75.
Second, we have to find the unit rate of the 4-oz jar. $2.92÷4=$73.
Third, we have to find the unit rate of the 8-oz jar. $5.68=$.71.
Fourth, we have to find the unit rate of the 16-oz jar. The division for this one may be tricky. From dividing $11.62 by 16, is stopped at the 3rd number I got from dividing. I got $.726. This is not a value of cents and the value can't go in the thousandths place. So, I rounded .726. I got $.73. So $11.62÷16=$.73.
Lastly, you have to compare the amounts.
The lowest amount or better buy, is $.71 or 8-oz jar.

How does the value of an expression change when it is expanded
Answer:
The value remains the same.
Step-by-step explanation:
using the expression: [tex](x + 1)^{2}[/tex],
where x = 2
substitute for x in the expression;
[tex](2 + 1)^{2}[/tex]
= [tex](3)^{2}[/tex]
=9
The value of the expression before expansion = 9
Lets expand the expression: [tex](x + 1)^{2}[/tex]
= (x + 1) (x + 1)
= [tex]x^{2}[/tex] + 2x + 1
substitute for x in the expression
= [tex]2^{2}[/tex] + 2(2) + 1
= 4 + 4 + 1 = 9
The value of the expansion after expansion = 9
The value remains the same before and after expansion.
The value of an expression, before and when it is expanded will be always same.
Let us consider that an expression,
[tex]f(x)=(x-1)^{2}[/tex]
Substitute x = 2 in above relation.
[tex]f(2)=(2-1)^{2}=1[/tex]
Now expand,
[tex]f(x)=(x-1)^{2}=x^{2} -2x+1\\\\f(2)=2^{2}-2*2+1\\\\f(2)=4-4+1\\\\f(2)=1[/tex]
Hence, the value of an expression, before and when it is expanded will be always same.

A room has dimensions 6.8m x 9.2m. Steven wants to paint the walls of the room. A large tin of paint covers 20m^2 and cost £11.75. Ignoring windows and doors, and allowing for 2 coats of paint, how much will it cost Steven to paint the room.
Answer:
Total cost to paint the room = £73.51
Step-by-step explanation:
Given:
Dimensions of the room = 6.8 m [tex]\times[/tex] 9.2 m
Cost of tin of paint = £11.75
A tin of paint covers an area = 20 [tex]m^2[/tex]
To find the cost of painting the room with two coats of paint.
Solution:
Area of the room = [tex]length\times width=6.8\ m\times 9.2\ m= 62.56\ m^2[/tex]
We will use unitary method to find the amount of paint required for the room.
If [tex]20\ m^2[/tex] of area is covered by 1 tin of paint.
For [tex]1\ m^2[/tex] of area, amount of paint required = [tex]\frac{1}{20}[/tex] of a tin
Then, for [tex]62.56\ m^2[/tex] amount of paint required = [tex]\frac{62.56}{20}=3.128[/tex] tins of paint.
For double coats twice paint must be required.
So, total amount of paint required for painting the room with two coats of paint = [tex]3.128\times 2=6.256[/tex] tins of paints.
Using unitary method to find total cost.
If 1 tin of paint costs = £11.75
6.256 tins of paint will cost = [tex]6.256\times \£11.75=\£73.508\approx\£73.51[/tex]
Total cost to paint the room = £73.51

what is the sum of 7.09 + 13.95
Answer:
21.04
Step-by-step explanation:
Start by adding the hundredths category. 0.09 + 0.05 = 0.14, this means that your hundredths column will be a 4, and you will carry the 1 over to the tenths.
Now add your tenths. 0.0 + 0.9 + 0.1 = 1.0, which means that your tenths column is a 0. Carry the 1 over to the whole numbers.
Now add your whole numbers. 7 + 13 + 1 = 21. Combine your terms and you get 21.04
Final answer:
21.04
Explanation:
To find the sum of 7.09 and 13.95, we simply add the two numbers together, aligning the decimal points vertically.
Add the hundredths place: 9 (from 7.09) + 5 (from 13.95) = 14. Write down 4 and carry over 1 to the tenths place.Add the tenths place: 0 (from 7.09) + 9 (from 13.95) + 1 (the carryover) = 10. Write down 0 and carry over 1 to the ones place.Add the ones place: 7 (from 7.09) + 3 (from 13.95) + 1 (the carryover) = 11. Hence, write down 1 and carry over another 1 to the tens place.Add the tens place, which is just the carryover: 1 (from the carryover) + 1 (from 13.95) = 2. So, write down 2.Putting it all together, we get 21.04 as the final sum.
An airplane has 29 seats. The price for a coach seat is $600 in the price for a first class seat is $1050. The airline collected a total of $21,900 for the flight. How many coach seats were sold
Answer:
19 coach seats
Step-by-step explanation:
let the number of coach seats be C and number of first class seats be F
given that the total number of seats is 29,
C + F = 29 ---------(eq 1)
also given that each coach seat = $600, each 1st class seat is $1050 and a total of $21900 was collected,
600C + 1,050F = 21,900 -------(eq 2)
we have 2 equations and 2 unknowns, we can solve the system of equations by elimination
(eq 1) x 1,050 gives us:
1,050 (C + F) = 1,050(29)
1,050C + 1,050F = 30,450 ----- (eq 3)
by elimination, subtract eq 2 from eq 3
(1,050C + 1,050F) - (600C + 1,050F) = 30,450 - 21,900
1,050C - 600C = 8,550
450C = 8550
C = 855 /450
C = 19

An electronics store makes a profit of $72.00 for every television sold and $90.00 for every computer sold. The manager’s target is to make at least $360.00 a day on sales from televisions and computers. Let x = the number of televisions sold. Let y = the number of computers sold. Which of the following represents three possible solutions to the problem?
A. 72x+90y>360 (5,2),(3,3) and (1,4)
B. 72x+90y<360 (4,0),(2,2) and (1,1)
C. 72x+90y>360 (3,1),(2,2) and (1,0)
D 72x+90y>360 (4,0),(3,3) and (1,4)
Answer:
Option A, C and D is the three possible solution.Step-by-step explanation:
Each Television earns $72 and each Computer earns $90.
The manager’s target is to make at least $360.00 a day.
It is not clarified the exact number of Televisions and Computers.
Hence, as per the given condition, [tex]72x + 90y \geq 360\\8x + 10y \geq 40\\4x + 5y \geq 20[/tex].
Now we just need to check the given options, whether they satisfy the above equation, or not.
Except the option B, each inequality indicates a value greater than 360.
Hence, option B can not be the possible solution.
To meet the profit target of 72x + 90y ≥ 360, the correct points are listed in Option A: (5, 2), (3, 3), and (1, 4). These points meet the required profit condition.
To solve this problem, we need to find the inequality that represents the manager's profit target and identify the solutions that meet this condition. Given:
The profit per television is $72 (x represents the number of televisions sold).The profit per computer is $90 (y represents the number of computers sold).The manager’s goal is to make at least $360. This can be represented by the equation: 72x + 90y ≥ 360.
We need to check which option lists points that satisfy this inequality. Let's test the points:
Option A: 72x + 90y > 360 (5, 2), (3, 3), and (1, 4)
(5, 2): 72(5) + 90(2) = 360 + 180 = 540 (satisfies ≥ 360)(3, 3): 72(3) + 90(3) = 216 + 270 = 486 (satisfies ≥ 360)(1, 4): 72(1) + 90(4) = 72 + 360 = 432 (satisfies ≥ 360)Option B: 72x + 90y < 360 (4, 0), (2, 2), and (1, 1)
(4, 0): 72(4) + 90(0) = 288 (does not satisfy ≥ 360)(2, 2): 72(2) + 90(2) = 144 + 180 = 324 (does not satisfy ≥ 360)(1, 1): 72(1) + 90(1) = 72 + 90 = 162 (does not satisfy ≥ 360)Option C: 72x + 90y > 360 (3, 1), (2, 2), and (1, 0)
(3, 1): 72(3) + 90(1) = 216 + 90 = 306 (does not satisfy ≥ 360)(2, 2): 72(2) + 90(2) = 144 + 180 = 324 (does not satisfy ≥ 360)(1, 0): 72(1) + 90(0) = 72 (does not satisfy ≥ 360)Option D: 72x + 90y > 360 (4, 0), (3, 3), and (1, 4)
(4, 0): 72(4) + 90(0) = 288 (does not satisfy ≥ 360)(3, 3): 72(3) + 90(3) = 216 + 270 = 486 (satisfies ≥ 360)(1, 4): 72(1) + 90(4) = 72 + 360 = 432 (satisfies ≥ 360)Only Option A lists points that all satisfy the inequality 72x + 90y ≥ 360. Therefore, Option A is the correct answer.

A typical marathon is 26.2 miles. Allan averages 12 kilometers per 1 hour when running in marathons. How long does it take for Allan to complete a marathon, to the nearest tenth of an hour.
Answer:
3.5 hours
Step-by-step explanation:
Given: Distance= 26.2 miles
Speed= 12 km/h
First lets convert the unit of speed from kmh to mph.
Remember, 1 mile= 1.609 km
∴ For speed of 12 km/h= [tex]\frac{12}{1.609}= 7.45\ mph[/tex]
Speed= 7.45 mph
Next, find time taken by Allan to complete a Marathon.
[tex]Time= \frac{Distance}{speed}[/tex]
⇒ Time= [tex]\frac{26.2}{7.45}[/tex]
∴ Time= 3.516 hours ≅ 3.5 h (nearest tenth)
∴ Allan took 3.5 hours to complete marathon.
Allan takes approximately 3.5 hours to complete a marathon. This is determined by converting the marathon distance to kilometers and dividing it by his running speed.
To determine how long it takes Allan to complete a marathon, we need to convert the marathon distance from miles to kilometers and then find the time it takes based on his running speed.
1 mile is approximately 1.60934 kilometers, so:
26.2 miles × 1.60934 km/mile ≈ 42.164 km
Allan runs at an average speed of 12 kilometers per hour. The time (t) needed to complete the marathon can be calculated as:
t = distance / speed
t ≈ 42.164 km / 12 km/h ≈ 3.514 hours
Rounding to the nearest tenth of an hour, Allan takes approximately 3.5 hours to complete the marathon.

You mix 1/3
quart of blue paint for every 1/2
quart of red paint to make 2 1/2
quarts of purple paint. How much blue paint and how much red paint do you use?
Answer:
1 quart blue + 1 1/2 quart red
Step-by-step explanation:
Given:
Ratio of blue paint : red paint = 1/3 : 1/2
simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:
(1/3) x (3x2) : (1/2) x (3x2)
2 : 3
From this we can determine the fractions of red and blue paint used in any total purple mix
fraction of blue paint = 2/(2+3) = 2/5 of purple mix
fraction of red paint = 3/(2+3) = 3/5 of purple mix
we are given that we want to make 2 1/2 (= 5/2) quarts of purple paint
hence
amount of blue paint
= fraction of blue paint in purple mix x total amount of purple paint
= (2/5) x (5/2) = 1 quart
amount of red paint
= fraction of redpaint in purple mix x total amount of purple paint
= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart

Sunil takes 5 more days than Anil to a certain work . Anil left the work after 4days,Sunil takes 5days to complete the rest work . How many days they took to complete the work
Answer:
Anil would take 10 days and Sunil would take 15 days to complete the work.
Step-by-step Explanation:
To Determine:
How many days they took to complete the work?
Information Fetching and Solution steps:
Sunil takes 5 more days than Anil to a certain workAnil left the work after 4 daysSunil takes 5 days to complete the rest workLet is consider,
The number of days taken by Anil to complete the required work = d.
The number of days taken by Sunil to complete the required work = d + 5
Work done by Anil in one day = 1÷d
Work done by Sunil in one day = 1÷ (d+5)
Work done together by Anil and Sunil for one day = 1/d + 1/(d+5)
= (d+5+d)/d(d+5)
= (2d+5)/d(d+5)
Work done together by Anil and Sunil for 4 days = 4×(2d+5)/d(d+5) ....[A]
Work done by Sunil in 5 days = 5÷ (d+5) ....[B]
By adding equation [A] and [B], we can determine the complete work
[A] + [B] = 1
((4×(2d+5)/d(d+5))) + (5÷ (d+5)) = 1
8d+20+5d=1d(d+5)
13d+20=d²+5d
−d²+8x+20=0
(−d−2)(d−10)=0
d=−2 or d=10
As number of days can not be negative. So, d = 10. Therefore,
The number of days taken by Anil to complete
the required work = 10 days
The number of days taken by Sunil to complete
the required work = d+5 = 15 days
Hence, Anil would take 10 days and Sunil would take 15 days to complete the work.
Keywords: days, work

Interest = interest rate x principal x time
Answer:
$280
Step-by-step explanation:
Interest = Interest Rate x Principal x time
Interest = 0.04 x $3,500 x 2
Interest = $280
Suppose you have $30 to spend on a bag is tootsie rolls that are worth $3 and bags of lolli-pops worth $5.If you have to use all of their money , What combinations of candy bags can they buy ? Construct a liner equation and find /explain the y -intercept,x-intercept ,and slope
Answer:
Part a) [tex]3x+5y=30[/tex]
Part b) see the explanation
Part c) see the explanation
Step-by-step explanation:
Part a) Construct a liner equation
Let
x ----> the number of bags of tootsie rolls
y ----> the number of bags of lolly-pops
we know that
The number of bags of tootsie rolls bought multiplied by their price ($3) plus the number of bags of lolly-pops bought multiplied by their price ($5) must equal $30
so
The linear equation that represent this problem is
[tex]3x+5y=30[/tex]
Part b) Find the intercepts
Find the y-intercept
The y-intercept is the value of y when the value of x s equal to zero
In this context, the y-intercept is the number of bags of lolly-pops that i can buy when the number of bags of tootsie rolls is equal to zero
For x=0
[tex]3(0)+5y=30[/tex]
[tex]y=6[/tex]
The y-intercept is the point (0,6)
so
I can buy 6 bags of lolly-pops and 0 bags of tootsie rolls
Find the x-intercept
The x-intercept is the value of x when the value of y s equal to zero
In this context, the x-intercept is the number of bags of tootsie rolls that i can buy when the number of bags of lolly-pops is equal to zero
For y=0
[tex]3x+5(0)=30[/tex]
[tex]x=10[/tex]
The x-intercept is the point (10,0)
so
I can buy 10 bags of tootsie rolls and 0 bags of lolly-pops
Part c) Find the slope
we have
[tex]3x+5y=30[/tex]
isolate the variable y
[tex]5y=-3x+30[/tex]
[tex]y=-\frac{3}{5}x+6[/tex]
The slope is m=-3/5 ---> is negative because is a decreasing function
That means ---> For every three less lollipops you get, you can have 5 more tootsie rolls

Write an expression equivalent to 4(6x + 12), and state the property you used to write it.
Answer:
4(6x) + 4(12)
Distributive property
4(6x + 12) = 4(6x) + 4(12)
To see if the answer is correct, we can solve the equations
24x + 12 = 24x + 12
The expressions are equal, so the equivalent expression provided is correct
Hope this helps :)
Answer:
By applying the Distributive Property, I can generate these equivalent expressions: 24x + 48, 24(x + 2), and 12(2x + 4).
Six cars pull up to a red light, one at a time. At the light, there are three lanes, one left-turn lane, one straight-going lane, and one right-turn lane. How many ways can the cars stack up so that all three lanes are occupied? Note that if the first car turns left and the second goes straight, this is considered different from the first car going straight and the second car turning left. In other words, the cars are distinguishable, but pull up to the intersection in a fixed order.
Answer: [tex]540[/tex]
We count the number of ways that some lane can be left empty, and subtract from the total:
Each driver has three choices, so it's [tex]3^6 = 729[/tex].
Now, we count the ways where at least 1 lane is left empty:
But we have double-counted the situations where two lanes are left empty. Since each driver only has one choice, there are [tex]3(1^6)[/tex] situations we overcount. This leaves [tex]729 - (192 - 3) = 540[/tex] ways to fill all three lanes.

Find the values of x and y.
X is a right angle so 90 degrees.
The B will be equal to C so B is 47 degrees.
The Y is 180 degrees - X - C so Y is 43 degrees.
