The expression 16t^2 represents the distance in feet the object falls after t seconds. The object is dropped from a height of 90

Shtirlitz [24]

Answer:

824 feet

Step-by-step explanation:

Given

$h(t) = 16t^2$

$H = 906$ -- Initial Height

Required

Determine its height after 2 seconds

First, we calculate the distance covered in 2 seconds

$h(t) = 16t^2$

$h(2) = 16*2^2$

$h(2) = 16*4$

$h(2) = 64$

This means that the object moved a distance of 64feet

So, the object height is calculate by subtracting the distance covered from the object's initial height:

i.e.

$Height = H - h(2)$

$Height = 906- 64$

$Height = 824$

Segment FG begins at point F(-2, 4) and ends at point G(-2, -3). The segment is translated 3 units left and 2 units up, then ref

Alexus [3.1K]

Answer:

$F'G' = 7$

Step-by-step explanation:

Given

$F = (-2,4)$

$G = (-2,-3)$

Required

Distance of F'G'

The transformation that give rise to F'G' from FG are:

Translation
Reflection

The above transformations are referred to as rigid transformation, and as such the side lengths remain unchanged.

i.e.

$F'G' = FG$

Calculating FG, we have:

$FG = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

Where:

$F = (-2,4)$ --- $(x_1,y_1)$

$G = (-2,-3)$ --- $(x_2,y_2)$

$FG = \sqrt{(-2 - -2)^2 + (4 - -3)^2}$

$FG = \sqrt{(0)^2 + (7)^2}$

$FG = \sqrt{0 + 49}$

$FG = \sqrt{49}$

Take positive square root

$FG = 7$

Recall that:

$F'G' = FG$

$F'G' = 7$
