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:
B = 40° and D = 60°
Step-by-step explanation:
Just subtract the angles you already know from 90° (since perpendicular means right angle, which is 90°).
What we know:
-volume of 10,000 drops is 10 fluid ounces
Step 1: Divide 10,000 by 10 (to find how much we need to divide 10 by to get our answer)
10,000/10=1,000
Step 2: Divide 10 by 1,000 (to find our answer)
10/1,000=0.01
Our answer is 0.01. The volume of 10 drops of liquid is 0.01 fluid ounces.
Answer:
450
Step-by-step explanation:
Multiply the length (30) by the width (15)
30x15=450
