The balloon reaches a height of 7 feet at 0.1 seconds and 2.13 seconds
<h3>How to determine the time the balloon is at the height?</h3>The equation of the function is given as
h(t)= -16t^2 + 35t + 5
The above equation is a quadratic equation
When the balloon is at a height of 7 feet, we have
h(t) = 7
So, we have the following equations
h(t)= -16t^2 + 35t + 5
h(t) = 7
Next, we plot the equations on a graph (see attachment)
The equations intersect at
t = 0.059 and t = 2.129
Approximate
t = 0.1 and 2.13
Hence, the times are 0.1 seconds and 2.13 seconds

Answer:
a) MARKUP PERCENT = 200%
b) <u>If the cost price of clothing A = $10</u>
then its retail price = $30
<u> If the cost price of clothing B = $25</u>
then its retail price = $75
Step-by-step explanation:
Let us assume the original price for the clothing = a
Now, boutique triples the price of the items it purchases for resale.
So, the resale value of the item of clothing = 3 times (Original price) = 3 a
So, here: The resale Value = 3 a
a) MARK UP Percentage =
or, the MARKUP PERCENT = 200%
b) Two expressions that represent retail price
<u>If the cost price of clothing A = $10</u>
then its retail price = 200% of 10 + 10 = 20 + 10 = $30
<u>If the cost price of clothing B = $25</u>
then its retail price = 200% of 25 + 25 = 50 + 25 = $75
