Frank builds a miniature model of a car based
on the dimensions of a popular car. He uses a
scale of 1 foot = 0.2 inch. Determine the length
of the miniature model, if the actual car is 13.5
feet long.

2.7 inches long

Step-by-step explanation:

cross multiply

1 * x = 13.5 * 0.2

x = 2.7

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
