Answer:

In other words, the base must be at least 9 feet long.
Step-by-step explanation:
The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet.
Recall that the area of a triangle is given by:

Since we want to area to be at least 36 square feet:

We are given that the height is eight feet. Substitute:

Simplify:

Divide both sides by four. Hence, our inequality is:

In words, this means that the base must be at least 9 feet long.

Step-by-step explanation:

height of ball (a) = 10m
fraction of height decreases by each bounce (r) = 2/3

The answer for this is less than 887
Answer:
9.694 years
Step-by-step explanation:
Let the investment is $P.
So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.
Let the time is y years.
So, from the formula of compound interest we can write
⇒
⇒
Now, taking log both sides we get,
y log 1.12 = log 3 {Since,
}
⇒ 0.04922y = 0.477712
⇒ y = 9.694 years (Answer)
