Answer:

Step-by-step explanation:

Given

Height of the rocket is given by

h=128t-16t^2

h=8\times 16t-16t\times t

(a)Greatest common factor in each term is 16t

(b)

h=8\times 16t-16t\times t

h=16t(8-t)

(c)

After t=4\ s

h=16\times 4(8-4)

h=256\ m

after t=6\ s

h=16\times 6(8-6)

h=192\ m

Thus after 4\ s height of rocket is greater .

A triangle is removed from the rectangle. Find the area of the remaining figure.
Mariulka [41]

Answer

C) 160 in^2


Step by step explanation

First, let's find the area of the rectangle.

Area of a rectangle = length x width

The area of the rectangle = 20 * 10

= 200 in^2

Now let's find the area of the triangle that is removed.

Area of a triangle = 1/2 base * height.

Here base = 10 and height = 8. Plug in these values into the formula, we get

Area of the triangle = 1/2 * 10*8

= 5* 8

The area of the triangle = 40 in^2

The area of the remaining figure = Area of the rectangle - area of the triangle

=  200 - 40

= 160 in^2

The answer is "160 in^2"

Thank you.

Combine the like terms to create an equivalent expression 5n-2n
inysia [295]

Answer:

The answer is 3n

Step-by-step explanation:

Since the expression has two numbers with the same variable, they are able to be combined.

We will subtract 2n from 5n, so 5n - 2n.

This results us with <u>3n</u>, since 5 - 2 equals 3.
