The linear function y=2x+28 models the average cost of a haircut in a certain city, where y, is the average price of a haircut x years after 2000. Find the slope for the model. Then describe what this means in terms of the unit rate of change in the average cost of a haircut over time.

Answer:

a) 8 apples

b) 5 oranges

c) 2 oranges and 6 apples

Step-by-step explanation:

a) 8 apples × 1$ = 8$ < 10$

b) 5 oranges × 2$ = 10$

c) 2 oranges × 2$ = 4$

6 apples × 1$ = 6$ (4+6=10)

Answer:

Step-by-step explanation:

The problem scenario gives rise to two equations. One describes the total number of fruit. It is plotted in blue. The other describes the total cost. It is plotted in red.

The total number of fruit will be 8 at any blue dot. (It will not cost $10 if that dot is not also red.) One such total is (4 apples, 4 oranges)

__

The total cost will be $10 at any red dot. (The fruit count will not be 8 if that dot is not also blue.) One such cost is (4 apples, 3 oranges)

__

The cost for 8 pieces of fruit will be $10 where the blue and red dots are plotted at the same point: (6 apples, 2 oranges)

Option C

Answer:

C.  [tex]y=x+200[/tex]

Step-by-step explanation:

Line of best fit (trendline) : a line through a scatter plot of data points that best expresses the relationship between those points.

All the given options for the line of best fit are linear equations.

Therefore, we can add the line of best fit to the graph (see attached), remembering to have roughly the same number of points above as below the line.

Linear equation:  [tex]y=mx+b[/tex]

(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)

From inspection of the line of best fit, we can see that the y-intercept (where x = 0) is approximately 200.  So this suggests that either option C or option D is the solution.

We can also see that slope (gradient) is approximately 1, as for every +100 increase in x, y increases by +100.

[tex]\textsf{slope = rate of change}=\sf\dfrac{change \ in \ y}{change \ in \ x}=\dfrac{100}{100}=1[/tex]

Therefore, this suggests that C is the solution and that the closest approximation to the line of best fit is [tex]y=x+200[/tex]

Answer:

0.15

Step-by-step explanation:

3/20= 0.15

15/100= 0.15

Answer:

True

Step-by-step explanation:

0.20*165=33

Answer:

With the definition of percentage. 20% of something means multiplying it by 20 and then dividing the result by 100. In our case, [tex]165.00 \times 20 \div 100 = 33.00[/tex]

Alternatively, convert it into a fraction. 20 is 1/5 of 100 (alternatively, you need to pick 20 five times to get 100), and then you just multiply

[tex]165.00 \times \frac15 = 33.00[/tex]

Manny's Music Rental:  y = 40 + 25x

Sid's Saxophones:   y = 25 + 30x

Step-by-step explanation:

Let x = number of months

Let y = total cost of renting a saxophone

Manny's Music Rental:  y = 40 + 25x

Sid's Saxophones:   y = 25 + 30x

Answer:

a) The differential equation for the velocity is given by

(dv/dt) = k(250 - v)

b) v(t) = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾

With units of km/h

Step-by-step explanation:

Acceleration, a ∝ (250 - v)

But acceleration is widely given as dv/dt

(dv/dt) ∝ (250 - v)

(dv/dt) = k(250 - v)

where k = constant of proportionality

(dv/dt) = k(250 - v)

b) (dv/dt) = k(250 - v)

dv/(250 - v) = k dt

∫ dv/(250 - v) = ∫ k dt

- In (250 - v) = kt + c (where c is the constant of integration)

v(0) = 0; meaning, at t = 0, v = 0

- In 250 = 0 + C

c = - In 250 = - 5.52

- In (250 - v) = kt - 5.52

In (250 - v) = 5.52 - kt

250 - v = e⁽⁵•⁵² ⁻ ᵏᵗ⁾

v = 250 - e⁽⁵•⁵² ⁻ ᵏᵗ⁾

With units of km/h

To Find:

Volume of the cylinder = ?

Solution:

The volume of cylinder is given as;

Volume  = π r ² h

9(3.14)8^2=1808.64

[RevyBreeze]

Solution:

Given:

Recall that the volume of the cylinder is πr²h. Now, let's use the formula to find the volume of the cylinder.

[tex]\bullet \rightarrow \pi r^{2} h = \text{Volume of cylinder}[/tex]

[tex]\bullet \rightarrow (\pi)(r^{2})( h) = \text{Volume of cylinder}[/tex]

[tex]\bullet \rightarrow (3.14)(8^{2})( 9) = \text{Volume of cylinder}[/tex]

[tex]\bullet \rightarrow (3.14)(64)( 9) = \text{Volume of cylinder}[/tex]

[tex]\bullet \rightarrow \boxed{1808.64 \ m^{2} = \text{Volume of cylinder}}[/tex]

Step-by-step explanation:

Answer:

16 times

Step-by-step explanation:

We first have to find the total amount of crayons:

[tex]3+7+4+8+2+1=25[/tex]

That means that the box contains a total of 25 crayons. Of those 25 crayons, 7 are blue and 1 is orange. That means every time one crayon is chosen from the box, there is an 8 in 25 chance it will be blue or orange. We can represent that chance as a fraction: [tex]\frac{8}{25}[/tex]

That [tex]\frac{8}{25}[/tex] chance occurs each time ONE crayon is chosen, so if we want to know how many times blue or orange will be chosen after 50 times, we can multiply that chance by 50.

[tex]\frac{8}{25}*50=400/25[/tex]

Then you simplify the fraction:

[tex]\frac{400}{25}=16[/tex]

That means that if you pull crayons from the box 50 times, a blue or orange crayon will be likely drawn around 16 times.

Answer:

Step-by-step explanation:

Transformations are used to change the orientation of a function to a new function. The graph of [tex]f(x) = x^2[/tex] will have its parabola widened when it changes to [tex]g(x) = 3x^2[/tex]

Given that

[tex]f(x) = x^2[/tex]

If the new function is:

[tex]g(x) = 3x^2[/tex]

It means that f(x) has been vertically translated by a scale factor of 3.

The graph will be affected such that the parabola of [tex]f(x) = x^2[/tex] will become widen when the coefficient changes to 3 i.e. [tex]g(x) = 3x^2[/tex].

Plug in the coordinate (5,9) into the equation

Answer:

m = 5

p = 10

Step-by-step explanation:

Part A

The dashes on the lines mean that the lines are equal in length.

Therefore, IJ = IH and HK = KJ

So as IJ = IH

⇒ 10 = 2m

⇒ m = 10 ÷ 2

⇒ m = 5

Part B

The line IK is the bisector of angle I since IJ = IH and HK = KJ

Therefore, 2p - 5 = p + 5

subtract p from both sides:

⇒ 2p - 5 - p = p + 5 - p

⇒ p - 5 = 5

Add 5 to both sides:

⇒ p - 5 + 5 = 5 + 5

⇒ p = 10

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

5x + 4y = - 40 ( subtract 5x from both sides )

4y = - 5x - 40 ( divide all terms by 4 )

y = - [tex]\frac{5}{4}[/tex] x - 10 ← in slope- intercept form

with y- intercept c = - 10 ⇒ (0, - 10 ) → B

Step-by-step explanation:

To find the y intercept of the line we must first write the equation in standard form which is

y = mx + c

where

m is the slope

c is the y intercept

So we have

5x + 4y = - 40

4y = -5x - 40

Divide both sides by 4

We have the equation as

[tex]y = - \frac{5}{4} x - 10[/tex]

From the question the y intercept is - 10

We have the final answer as

Answer:

B

Step-by-step explanation:

Just did the test. Wish you luck!!

The equation of line is y = ( 3/2 )x - 7 , where the slope is m = 3/2

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = 3/2

The y-intercept is b = -7

And , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

So , y = ( 3/2 )x - 7

Hence , the equation of line is y = ( 3/2 )x - 7
