Answer:
- 1.875 seconds to reach the maximum height
- 62.25 ft
Step-by-step explanation:
The problem can be solved by putting the equation into vertex form.
s - 6 = -16(t^2 -15/4t)
s -6 -16(15/8)^2 = -16(t^2 -15/4t +(15/8)^2) . . . . add the square of half the x-coefficient inside parentheses and equivalent amount on the other side of the equation
s -62.25 = -16(t -15/8)^2 . . . . write as a square, simplify the constant
s = -16(t -1.875)^2 +62.25 . . . . put in vertex form
The vertex of the downward-opening parabola is at (t, s) = (1.875, 62.25).
1. It took 1.875 seconds for the ball to reach its maximum height.
2. The ball went up to 62.25 feet.
In this problem, you need to figure out whats 23% of 29% to find the percentage of the total group becoming vegetarians.
In order to do this, you can convert the percentages to decimals and multiply.
.23 x .29 = .0667 or 6.67%
6.67% of the total group are considering becoming vegetarians.
The area is about 28.25m²
Answer:-9-(-4)
Step-by-step explanation:
You start with -9 and then then when u distribute the - to the -4 it will become - 9+ 4
