Answer:
Just use long subtraction by expanding the decimal places of the whole number. This is done by adding a point, and enough zeros to it to match the number of decimal digits in the other number (digits after the decimal point).
12345678
i.e: 5 - 2.48374827, 2.48374827 has 8 decimal digits, so add 8 zeros after the point.
=
1 1 1 1 1 1 1
5.00000000
-

This is basically borrowing a group of 10s which are the same as 1s in the next decimal place up.
For each digit except the first to the right, let 10 subtract that number from it and minus 1 since the 1 is carried over.

Step-by-step explanation:
whats your question
PART A
The given equation is

In order to find the maximum height, we write the function in the vertex form.
We factor -16 out of the first two terms to get,

We add and subtract

to get,

We again factor -16 out of the first two terms to get,

This implies that,

The quadratic trinomial above is a perfect square.

This finally simplifies to,

The vertex of this function is

The y-value of the vertex is the maximum value.
Therefore the maximum value is,

PART B
When the ball hits the ground,

This implies that,

We add -29 to both sides to get,

This implies that,




or

Since time cannot be negative, we discard the negative value and pick,
Answer:
2.016
Step-by-step explanation:
In your equasion, I couldn't tell if you need to multipy 0.8^2 by 3.15 or are you asking something else? If you want to multiply, the answer is 2.016.
