We are given that

y-scale is a distance in miles

x-scale is a time in hours

and we are given

The graph of the distance a car travels at a constant speed passes through the points (0,0) and (2,136)

so, points would be

(0,0)

x1=0 , y2=0

(2,136)

x2=2 , y2=136

so, slope would be speed

because speed = distance / time

we can use slope formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{136-0}{2-0}

m=68 miles per hour

so, option-B..........Answer

The cost to ride a ferris wheel is $2.00 per person. The ferris a wheel has a capacity of
irakobra [83]

Answer:

When we have a function f(x), the domain of the function is the set of all the inputs that "work" (Not only in a mathematical way, the context is also important) with the function f(x)

In this case, we have a function M(p) = $2*p

This function represents the amount of money collected depending on the number of people who ride on the ferris whell.

Then p can be only a whole number (we can not have 1.5 people, only whole numbers of people).

And we also know that the maximum capacity of the ferris is 64 people.

Then:

p ≤ 64

And we also should add the restriction:

0 ≤ p ≤ 64

(Because p can't be smaller than zero)

Such that p should also be an integer, then, the domain is:

D: p ∈ Z, p ∈ {0, 1, 2, ..., 64}

Explain how you would find the perimeter of this triangle.
Lynna [10]

Answer:

<em>15.4 </em>

Step-by-step explanation:

\frac{u}{4} = tan51.3° ⇒ u = 4tan51.3° ≈ 5

\frac{4}{v} = cos51.3° ⇒ v = \frac{4}{cos51.3} ≈ 6.4

<em>P </em>≈ 4 + 5 + 6.4 = <em>15.4</em>
