Answer:

[tex]f(t)=43,200-7200t[/tex]

Step-by-step explanation:                      

We have been given that a delivery company purchased a new delivery truck for $43,200. The depreciated value of the truck can be estimated by the number of t years in service. The truck depreciates at a rate of $7,200 per year.

This means that after t years truck will depreciate 7200t. To find the truck's depreciated value after t years we will subtract 7200t from the cost of new delivery truck (43,200).  

[tex]f(t)=43,200-7200t[/tex]          

Therefore, the function [tex]f(t)=43,200-7200t[/tex] could be used to estimate the truck's depreciated value after t years.

The depreciated value of the truck after t years can be estimated by the linear function ƒ(t) = 43200 - 7200t, reflecting a straight-line depreciation method at a rate of $7,200 per year.

To estimate the depreciated value of the delivery truck after t years, we can use a linear equation which reflects a straight-line depreciation method. Since the truck cost $43,200 and depreciates at a rate of $7,200 per year, the equation representing the depreciated value of the truck after t years would be ƒ(t) = 43200 - 7200t. This equation starts with the initial value of the truck and subtracts the depreciation cost multiplied by the number of years the truck has been in service.

Depreciation is a way businesses can allocate the cost of a physical asset over its useful life. In this case, each year the truck is in service, it loses $7,200 in value. After one year, the value of the truck would be $43,200 - $7,200, which equals $36,000, and you would continue to subtract $7,200 for each additional year to determine the truck's value at any given time.

Answer:

option A  :  graph is a function

Step-by-step explanation:

(a) option is given is a graph

For graph , the function should pass vertical line test

Draw vertical line for every value of x

The vertical lines cross only one red point at a time

So the graph is a function

(b) When each input has only one output then it is a function

in option B , input 3 has two output -5  and 0

so it is not a function

(c) in option C , input 3 has two output 14  and 19

so it is not a function

(d) in option d , input -1 has two output -11  and 5

so it is not a function

The units are stokes per hole or strokes / hole

Jordan had the lowest number of strokes / hole followed by Rickie and finally Rory.

Answer:

Jordan had the lowest number of strokes per hole

Step-by-step explanation:

1) Total holes played by Rory = 9

Total strokes of Rory = 42

Number of stroke per hole: Rory

[tex]\frac{42 strokes}{9 hole}=4.667 strokes/hole[/tex]

2)Total holes played by Jordan = 18

Total strokes of Jordan = 79

Number of stroke per hole: Jordan

[tex]\frac{79 strokes}{18 hole}=4.389 strokes/hole[/tex]

3) Total holes played by Rickie  = 27

Total strokes of Rickie = 123

Number of stroke per hole: Rickie  

[tex]\frac{123 strokes}{27 hole}=4.556 strokes/hole[/tex]

4.667 strokes/hole > 4.556 strokes/hole > 4.389 strokes/hole

Rory > Rickie > Jordan

Jordan had the lowest number of strokes per hole

Considering the expression of a line, the equation of the line that passes through the pair of points (-66) and (3,-2) is 8/9x +y= 2/3.

Linear equation

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in the expression y = mx + b, the value of the ordinate to the origin b can be obtained.

The standard form of the line is Ax +By= C

Equation in this case

In this case, being (x₁, y₁)= (-6, 6) and (x₂, y₂)= (3, -2), the slope can be calculated as:

m= (-2 - 6)÷ (3 - (-6))

m= (-2 - 6)÷ (3 + 6)

m= (-8)÷ 9

m= -8/9

Considering point 2 and the slope, you obtain:

-2= (-8/9)×3 + b

-2= -8/3 + b

-2 +8/3= b

2/3= b

The equation of the line is y= -8/9x +2/3.

Finally, the standard form of the line is 8/9x +y= 2/3

18. Answer: D

Step-by-step explanation:

First, find the measure of the missing angle.

65° + 57° + x = 180°

      122° + x = 180°

                x = 58°

Next, match up the angles with the opposite sides:

65° ⇄ Swim

58° ⇄ Bike

57° ⇄ Run

Lastly, put them in order from least to greatest:

   57° < 58° < 65°

⇒ Run < Bike < Swim

The only multiple choice option that is correct is Bike > Run.

1. The graph of y=2/3x-2 is the top right corner, the -2 in the equation makes the line cross the y axis at -2

2. The slope is always with x and the y intercept is the second part of the equation.

The equation would be y = 5/6x -3

3.  The slope is the change in Y over the change in X

slope = 10-7 / 2 -  -1 = 3/3 = 1

Using the line formula y = mx+b, solve for b using the first point and the slope:

7 = 1 (-1)x +b

b = 7+1

b =8

The equation is -x +y =8

4. the jar starts with 6 , then they add 2 each day, multiply 2 by the number of days (x) and add it to 6:

The equation would be y = 2x + 6

5. point (5,9) slope = 2

Point-slope formula is written as y - y1 = m(x-x1)

y1 = 9, x1 = 5, m = 2

equation becomes y-9 =2(x-5)

Answer:

The answer is the first graph

The equation is y = 5/6x -3

The next equation is -x +y =8

The equation after would be y = 2x + 6

And, the final answer is y-9 =2(x-5)

Hope this helps!

Answer:

y=8

Step-by-step explanation:

We need to find the equation for the line.

The first step is to find the slope

We need 2 points  (0,2) (2,3)

slope = (y2-y1)/(x2-x1)

          = (3-2)/(2-0)

          = 1/2

We know the y intercept ( where it crosses the y axis)  at 2

Lets use the slope intercept form of the line

y= mx+b

y = 1/2 x+2

If we want to find the value of y when x =12 , substitute the value of x=12

y =1/2 * 12 +2

y = 6+2

y=8

Answer:

The opposite of Carlos's elevation would be +12ft.

Step-by-step explanation:

This question is using positive and negative integers to represent elevation and descending.  The surface of the pool would represent an elevation of 0, where we are level.  However, when Carlos descends (swims to the bottom) of the pool, he is at an elevation of -12 because he is below the surface.  The opposite of -12 would be +12.  So the opposite of where Carlos is -12ft below the surface of the water would be +12 foot above the surface of the water.  

Answer:

The correct answer has already been given (twice). I'd like to present two solutions that expand on (and explain more completely) the reasoning of the ones already given.

One is using the hypergeometric distribution, which is meant exactly for the type of problem you describe (sampling without replacement):

P(X=k)=(Kk)(N−Kn−k)(Nn)

where N is the total number of cards in the deck, K is the total number of ace cards in the deck, k is the number of ace cards you intend to select, and n is the number of cards overall that you intend to select.

P(X=2)=(42)(480)(522)

P(X=2)=61326=1221

In essence, this would give you the number of possible combinations of drawing two of the four ace cards in the deck (6, already enumerated by Ravish) over the number of possible combinations of drawing any two cards out of the 52 in the deck (1326). This is the way Ravish chose to solve the problem.

Another way is using simple probabilities and combinations:

P(X=2)=(4C1∗152)∗(3C1∗151)

P(X=2)=452∗351=1221

The chance of picking an ace for the first time (same as the chance of picking any card for the first time) is 1/52, multiplied by the number of ways you can pick one of the four aces in the deck, 4C1. This probability is multiplied by the probability of picking a card for the second time (1/51) times the number of ways to get one of the three remaining aces (3C1). This is the way Larry chose to solve the this.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

The number of new houses = 3

The number of old houses = 7

So , the ratio of old houses to new houses = number of old houses : number of new houses

Substituting the values in the equation , we get

Ratio of old houses to new houses = 7 : 3

Now , the number of new houses = 15

So , the number of old houses A is given by the proportion equation ,

7 : 3 : : A : 15

On simplifying the equation , we get

7/3 = A / 15

Multiply by 15 on both sides of the equation , we get

A = ( 7 x 15 ) / 3

A = 7 x 5

A = 35 houses

Therefore , the value of A is 35 houses

Hence , the number of old houses is 35

Final answer:

The correct number of old houses is found by determining how many times the 3:7 ratio of new to old houses fits into the 15 new houses and then applying that to the 7 old houses in the ratio, which results in 35 old houses.

Explanation:

The question asks to find the number of old houses in a city given the ratio of new to old houses and the number of new houses. There is a ratio of 3 new houses for every 7 old houses. If there are 15 new houses, we need to find how many times the ratio fits into the number of new houses and then apply that same multiplier to the number of old houses.

To find this, we divide the number of new houses by the number of new houses in the ratio:

Number of times the ratio fits = 15 new houses ÷ 3 new houses per ratio = 5 times

Now, we multiply the number of old houses in the ratio by 5:

Number of old houses = 7 old houses per ratio × 5 times = 35 old houses

Therefore, the correct answer is B. 35.

Step-by-step explanation:

The equation of inverse variation is

y = k/x,

where k is a constant.

We can use the given x- and y-coordinates to find k.

y = k/x

15 = k/11

k = 165

The inverse variation equation for this problem is

y = 165/x

For y = 3,

3 = 165/x

3x = 165

x = 55

Answer:

C

Step-by-step explanation:

given x varies inversely as y then the equation relating them is

x = [tex]\frac{k}{y}[/tex] ← k is the constant of variation

To find k use the given condition x = 11 when y = 15

k = xy = 11 × 15 = 165 , hence

x = [tex]\frac{165}{y}[/tex] ← inverse variation equation

when y = 3, then

x = [tex]\frac{165}{3}[/tex] - 55 → C

Answer:

the only point is (0,1) if u would look at the graph i post

Step-by-step explanation:

The point which lies on the graph of f(x) = (1/3)x will satisfy the function thus point (-1, -1/3) will lie on the graph thus option (D) is correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

As per the given function,

f(x) = (1/3)x

Substitute, x = 0,

y = f(0) = (1/3)0 = 0

So,(0,1) will not lie on the graph.

Similarly, (3, 27) and (−2, 9) also do not lie on the graph.

Substitute (-1,-1/3)

-1/3 = (1/3)(-1) = -1/3

Thus, it will be the point of the function.

Hence "The point which lies on the graph of f(x) = (1/3)x will satisfy the function thus point (-1, -1/3) will lie on the graph".
