PLEASE HELP ME PLS ITS MATH

Mathematics
1 answer:
Ganezh [65]1 year ago
7 0

Answer:

9

Step-by-step explanation:

We know that

h(t)=-16t^2+1296

The balls hits the ground when h(t)=0, so

-16t^2 + 1296=0 \\ \\ t^2 - 81=0 \\ \\ t^2 = 81 \\ \\ t=9

Note I only considered the positive case because time must be positive.

If an answer for this question is not a whole number, enter it as a decimal.
Naily [24]

Answer:  The answer would be A.  Or if that is what you are asking.

Step-by-step explanation:

When you multiply decimals, you multiply like how you would for any other set of numbers. (It doesn't matter if you line the decimal points up or not.)

The only difference between multiplying normal numbers and decimals is the decimal point. How many digits there are to the right of the decimal point is how many times you move the decimal point for the new number to the left.

In the decimals 5.15 and 0.3, there are three digits to the right of the decimal in all, so, when you work this problem and come out with 1545, you move the decimal point to the left three times.

1^545

So the decimal point goes right between the 1 and the 5.

Hope I made it clear enough
