Answer: 2(4 + x)

Step-by-step explanation:

i just multiplied across the parentheses. we can rule out the first option, because it would multiply out to be 8 + 4x.

the second option is the one that i calculated second, so i knew that i could rule out the last one my default.

just for kicks, if we multiplied the third option, it would come out to 8 + 4x.

A rocket carrying fireworks is launched from a hill 60 feet above a lake. The rocket will fall into the lake after exploding at

castortr0y [4]

Answer:

Step-by-step explanation:

Given the rocket's height above the surface of the lake given by the function h(t) = -16t^2 + 96t + 60

The velocity of the rocket at its maximum height is zero

v = dh/dt = -32t + 96t

At the maximum height, v = 0

0 = -32t + 96t

32t = 96

t = 96/32

t = 3secs

Substitute t = 3 into the modeled function to get the maximum height

h(3) = -16(3)^2 + 96(3) + 60

h(3) = -16(9)+ 288 + 60

h(3) = -144+ 288 + 60

h(3) = 144 + 60

h(3) = 204

Hence the maximum height reached by the rocket is 204m

Get the height after 2 secs

h(t) = -16t^2 + 96t + 60

when t = 2

h(2) = -16(2)^2 + 96(2) + 60

h(2) = -64+ 192+ 60

h(2) = -4 + 192

h(2) = 188m

Hence the height of the rocket after 2 secs is 188m

A restaurant supplier receives a discount on each oven purchased. The original price of each oven is x dollars. The restaurant s

Sauron [17]

Answer:

Each oven is discounted by $20.

Step-by-step explanation:

Original price of oven in dollars = $x$

To find total cost for 9 such ovens without discount we will apply unitary method.

If 1 oven costs in dollars = $x$

Then 9 ovens will cost in dollars = $9x$

The ovens are purchased by a restaurant supplier at some discounted price.

The new price after discount in dollars = $9x-180$

We see that the total cost of 9 ovens which was originally $=9x$ has been decreased to $=9x-180$ after discount.

The decrease amount is the discount amount on 9 ovens which is = $180

To find discount offered on each oven, we will again use unitary method.

Discount on 9 ovens = $180

∴ Discount on 1 oven = $\frac{\$180}{9}=\$20$

∴ Each oven is discounted by $20.
