The function f(t) = 4t2 ? 8t + 8 shows the height from the ground f(t), in meters, of a roller coaster car at different times t. write f(t) in the vertex form a(x ? h)2 + k, where a, h, and k are integers, and interpret the vertex of f(t). (1 point) f(t) = 4(t ? 1)2 + 2; the minimum height of the roller coaster is 2 meters from the ground f(t) = 4(t ? 1)2 + 2; the minimum height of the roller coaster is 4 meters from the ground f(t) = 4(t ? 1)2 + 4; the minimum height of the roller coaster is 1 meter from the ground f(t) = 4(t ? 1)2 + 4; the minimum height of the roller coaster is 4 meters from the ground

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

a
