I need help with another set of math questions.

1 answer:

7 0

For question 11, you essentially need to find when h(t) = 0, since that is when the height of the ball reaches 0 (ie touches the ground).

For question 12, it is asking for a maximum height, so you need to find when dh/dt = 0 and taking the second derivative to prove that there is maximum at t. That will find you the time at which the ball will hit a maximum height.

Rinse and repeat question 12 for question 13

At 3 P.M., the temperature is 12°F. It then began dropping 2°F every hour for 7 hours. What was the temperature after 7 hours?

fiasKO [112]

All you need to do to answer this question is multiply 2 (the dropping temperature) by 7 (time in hours) which is 14. Subtract 14 from 12 and your answer is -2 degrees Fahrenheit

the area of a triangle is 6 and 3/8 square yards. The height of the triangle is 2 and 1/2 yards. What is the length of the base

Otrada [13]

Solution:

Area of triangle = 6 3/8 yd²
Height of triangle = 2 1/2
Area of triangle = 1/2 x base x altitude

<u>Use the formula to find the base of the triangle.</u>

1/2 x base x altitude = 6 3/8 yd²
=> 1/2 x base x 2 1/2 = 6 3/8 yd²
=> 1/2 x base x 5/2 = 6 3/8 yd²
=> 5/4 x base = 6 3/8 yd²
=> base = 6 3/8 ÷ 5/4 yd
=> base = 51/8 x 4/5 yd
=> base = 51/2 x 1/5 yd
=> base = 51/10 yd

The length of the base is 51/10 yards.
