Answer: 94
Step-by-step explanation:
You invest $5,175.00 in a stock plan. It increases 9% the first year and then losses 5% of its value the second year. What is your gain compared to you original investment?
Answer: $183.71
Step-by-step explanation:
Original amount is $5,175.00
1st year: Increase of 9%
→ $5175(1 + 0.09)
= $5175(1.09)
= $5640.75
2nd year: Decrease of 5%
→ $5640.75(1 - 0.05)
= $5640.75(0.95)
= $5358.71
Gain: 2nd year - Original
→ $5358.71 - $5175.00
= $183.71
Answer:
$183.7
Step-by-step explanation:
We know that $5,175.00 was invested in a stock plan.
It increased by 9% in the first year:
[tex] 9% \times 5175.00 = 465.75 [/tex]
So value reached to (5175 + 465.75 = ) $5640.75
Then it second year, it lost 5% of its value:
[tex] 95% \times 5640.75 = $5358.7 [/tex]
Therefore, the gain compared to the initial original investment will be:
$5358.7 - $5175.0 = $183.7

a square tile is 20 cm wide. How many tiles are needed to cover 2 square metres
Answer:
50 tiles
Step-by-step explanation:
The area of a square is the square of the side. The area of each tile is
a = (20 cm)^2 = 20 cm * 20 cm = 400 cm^2
Now we convert 2 square meters into square centimeters.
2 m^2 * (100 cm)/m * (100 cm)/m = 20,000 cm^2
2 m^2 = 20,000 cm^2
Now we divide the total area by the area of one tile.
(20,000 cm^2)/(400 cm^2) = 50
Answer: 50 tiles
Consider the following equation.
5x^2 - 3x + 10 = (3x + 4)^2
If the above quadratic equation were used to solve for x, which of the following are the values for a,b, and c
A. a= 3,b = 12,c = 16
B. a=4,b =27,c = 6
C. a = 4,b =27,c = 26
D. a= 5,b = 3,c = 10
Answer:
B
Step-by-step explanation:
Expand the right side of the equation

If the lengths of an object are measured in feet, then the area of the object will be measured in what measurement?
Answer:
Square feet.
Step-by-step explanation:
Feet are an example of what are called linear units. They're used to measure one dimensional things like length, width, or height. Area is two-dimensional, it takes up (flat) space, so we need to measure it in units that do the same thing. The simplest two-dimensional shapes to measure area with turn out to be squares (since the area of a square with side length s is just s²), so we usually measure area in square units. Since our linear units here are feet, the corresponding square units will be square feet.
Answer:
I think the answer is square feet.

Given that (4,4) is on the graph of f(x), Find The Corresponding Point for the function f(x)+5
Answer:
(4,9)
Step-by-step explanation:
If f(x) is a function, the function f(x) + a is a function translated a units up vertically. Hence, all the y-coordinates of the coordinates of the points on the function will shift up by a.
For this problem, we need to find corresponding coordinate of (4,4) of f(x) + 5. This means that the y-coordinate of this coordinate will increase by 5 and x will stay the same.
Hence, corresponding point for f(x) + 5 for the point (4,4) would be (4,4+5) OR (4,9).
to fill out a sign chart, you will need to use test numbers before and after each of the function's zeros and ___
A. proportions
B. values
C. asymptotes
D. expressions
which fills the blank correctly
Answer:
C. asymptotes
Step-by-step explanation:
In the figure attached, a sign chart is shown. To fill it out you need to find the function's zeros and asymptotes. The zeros are those x values that makes the function equal to zero, in the example, those are the x values that make the denominator equal to zero (x = -1 and x = 5). In a rational function, the asymptotes are those x values that make the numerator equal to zero (x = -9 in the example)
Function in the example:
[tex]\frac{(-2x-2)(2x-10)}{-9x-81} [/tex]
Final answer:
To complete a sign chart accurately, one needs to use test numbers surrounding each of the function's zeros and asymptotes, determining the sign of the function in those intervals. This helps in understanding the behavior of the function and solving inequalities.
Explanation:
To fill out a sign chart, you will need to use test numbers before and after each of the function's zeros and C. asymptotes which fills the blank correctly. When you're dealing with functions, especially rational functions, the sign of the function can change around its zeros and asymptotes. Zeros are the points where the function crosses the x-axis, and the function's value is zero. Asymptotes, on the other hand, are lines that the function approaches but never touches; the function's value heads towards positive or negative infinity as it gets close to an asymptote.
When creating a sign chart, you select test numbers from intervals between these critical points -- zeros and asymptotes -- to determine if the function is positive or negative in those intervals. This process helps to understand the behavior of the function across its domain and is essential in solving inequalities.
Here's an example:
Identify the zeros and asymptotes of the function.
Place these values in increasing order on a number line to define test intervals.
Choose a test number from each interval and substitute it into the function to check the sign.
Fill in the sign chart with the corresponding signs for each interval.

Start with (-7)²
----------
(-7)^(-1)
Apply the rule that:
x^a
----------- = x^(a-b)
x^b
Then our:
(-7)²
----------- = (-7)^(2 - [-1] ) = (-7)^(2+1) = (-7)³
(-7)^(-1)
This answer could be left as is, or we could rewrite (-7)³ as
-7³, since (-1)³ = -1
Answer: FIRST OPTION
Step-by-step explanation:
According the quotient of powers property, when you have the division of two powers with the same base, then you must subtract the exponents.
Therefore, keeping the property above on mind, you have that the quotient is the shown below:
[tex]\frac{(-7)^2}{(-7)^{-1}}=(-7)^{(2-(-1))}=(-7)^{(2+1)}=(-7)^3=-343[/tex]

2/3 and add 1 to the numerator to get a whole number so 1 (whole number ) minus 2/3 is 1/3.
Perform the indicated operation. 4/7x^2 - 3/2x^3
"The correct operation to perform is the subtraction of the two given polynomial terms:
[tex]\[ \frac{4}{7}x^2 - \frac{3}{2}x^3 \][/tex]
To subtract these terms, we simply combine them, keeping in mind that subtraction requires us to change the sign of the term being subtracted and then add the terms together. Since the terms are already in descending powers of \( x \), we do not need to rearrange them. The subtraction then yields:
[tex]\[ -\frac{3}{2}x^3 + \frac{4}{7}x^2 \][/tex]
This is the simplified expression after performing the indicated operation. There are no like terms to combine further, so this is the final answer.
The answer is: [tex]\[ -\frac{3}{2}x^3 + \frac{4}{7}x^2 \]"[/tex]
Subtract [4 -4 -2] - [4 -3 5]
For matrix subtraction, you subtract the corresponding cell of the second matrix from the first. So, looking at the first spot, you have 4 (from the first matrix) - 4 (from the second matrix) = 0 (the first number in the output matrix). Continuing that for the next spot, -4 - -3 = -4 + 3 = -1. Finally, -2 - 5 = -7. This means your answer is [0 -1 -7].
The product (x) of two numbers is 24 and their sum (+) is 10. What is the value of the largest of the two numbers?
To find the largest of two numbers when given their product and sum, we can use the quadratic formula. Let's denote the numbers as 'a' and 'b'. We know that 'a * b = 24' and 'a + b = 10'. We can rewrite the second equation as 'b = 10 - a' and substitute it into the first equation. Solving the quadratic equation, we find that the larger of the two numbers is 6.
Explanation:To find the largest of two numbers when given their product and sum, we can use the quadratic formula. Let's denote the numbers as 'a' and 'b'. We know that 'a * b = 24' and 'a + b = 10'. We can rewrite the second equation as 'b = 10 - a' and substitute it into the first equation.
Substituting 'b' into the equation 'a * b = 24', we get 'a * (10 - a) = 24'. Expanding and rearranging the equation, we have 'a^2 - 10a + 24 = 0'. Solving this quadratic equation, we find that the values of 'a' are 4 and 6. Therefore, the larger of the two numbers is 6.

imagine you live only one mile from work and you decide to walk. if you walk four miles per hour, how long will it take you to walk one mile?
Answer:the distance to work is 1 mile and you can walk at 4 miles per hour, then you can walk 1 mile in ¼ hr = 15 minutes
Step-by-step explanation:
Dylan,
If the distance to work is 1 mile and you can walk at 4 miles per hour, then you can walk 1 mile in ¼ hr = 15 minutes.
To set up the "equation" think about it this way: (1 mile/ t) = (4 mile/ 1 hr)
so 1/t = 4/1 hr
now multiply both sides by t to get 1 = t·(4/1 hr), next divide both sides by (4/1 hr)
t = 1/(4/ 1 hr) = 1 hr/4 = ¼ hr = 15 min.
The answer is 15 minutes because if he can walk 4 miles for only an hour and we know that an hour is 60 minutes
4. 60m
1. 15m
So what I have done there is just divide it by 4 to get one mile and divide 60 by 4 to get the 15 minutes

Answer:
The central angle ADC = 81°
Step-by-step explanation:
From the figure we can see a circle with circumference = 200 cm and arc ABC length = 45 cm
To find the central angle ADC
Circumference = 200 cm
Length of arc ABC = 45
we have
arc length = circumference * (central angle /360)
central angle = (arc length * 360)/circumference
= (45 * 360)/200
= 81 cm
Therefore the central angle ADC = 81°
Answer:
ADC=81

The catch is to put this into the quadratic and solve for a b and c in three equations.
x = 1
a(1)^2 + b(1) + c= 0
a + b + c + 0 (1)
x = - 1
a(-1)^2 + b(-1) + c = 2
a - b + c = 2 (2)
x = 2
a(2)^2 + b(2) + c = 8
4a + 2b + c = 8 (3)
===================
Add 1 and 2 together
a + b + c = 0
a - b + c = 2
2a + 2c = 2 Divide by 2
a + c = 1 (4)
=====================
Multiply (2) by 2
2a - 2b + 2c = 4 (5)
======================
Add (5) + (3)
2a - 2b + 2c = 4
4a + 2b + c = 8
6a + 3c = 12 (6)
=====================
Multiply (4) by 3
3a + 3c = 3 (7)
===================
Subtract (7) from (6)
6a + 3c = 12
3a + 3c = 3
3a = 9 Divide by 3
3a/3 = 9/3
a = 3
=============
Use (4) to find c
a + c = 1
3 + c = 1 Subtract 3 from both sides
3-3 + c = 1-3
c = - 2
=================
Use 1 to find b
3 + b - 2 = 0 Combine 3 and -2
1 + b = 0 Subtract 1 from both sides
b = - 1
