Answer:

Step-by-step explanation:
Given


Required:
Determine the time taken to return to the ground
From the equation given; height (h) is a function of time (t)
When the rocket returns to the ground level, h(t) = 0
Substitute 0 for h(t) in the given equation

becomes

Solve for t in the above equation

Factorize the above expression

Split the expression to 2

Solving the first expression

Divide both sides by -4



Solving the second expression

Add 30 to both sides


Divide both sides by 4



Hence, the values of t are:
and 
shows the time before the launching the rocket
while
shows the time after the rocket returns to the floor
The one that should be performed according to the order of PEMDAS is 14 times 8.

Can I get a brainlist
The purchase price of the stock includes the commission paid
to the stockbroker. You have to multiply the cost per stock of the stock to the
number of shares purchased by Maureen to get the purchase price. You have to
multiply the purchase price with the percentage of commission to get the
commission. You add the purchase price and the commission to get the total
purchase price of the stock.
200 shares x $12.5 per share = $2,500
$2,500 x 1% commission
= $25
Total purchase price = $2,525
Answer:
3.25=x
Step-by-step explanation:
start with -5=4x+8
subtract 8 from each side to get:
-13=4x
divide each side by 4 to get your answer:
-3.25=x-
