0.21951 Reapeating cause the decimal does not terminate
It is neither. Distributive is like 20x9 20x5 then add those products. Associative is like (20x9) x5. You can however use both for this equation
The first thing we are going to do in this case is to rewrite the function:
f (x) = - 16x ^ 2 + 48x
We look for the first derivative:
f '(x) = - 32x + 48
We match zero:
0 = -32x + 48
We clear x:
32x = 48
x = 48/32 = 24/16 = 12/8 = 6/4 = 3/2
x = 3/2
We verify if this value is a maximum or minimum with the second derivative:
f '' (x) = - 32
We evaluate in x = 3/2:
f '' (3/2) = - 32 (<0 Is a maximum)
Therefore the maximum height is reached in:
x = 1.5 s
The height is:
f (1.5) = - 16 * (1.5) ^ 2 + 48 * (1.5)
f (1.5) = 36 feet
Answer:
The maximum height of the ball is:
36 feet
and it takes the ball to reach that height about:
1.5 s
Answer:
5.7km
Step-by-step explanation:
-let the drive east be the base of our 'triangle' and the drive north be the height, h.
-The distance from the parents to the grandparents, 9km, forms the hypotenuse.
#Using Pythagorean Theorem, we can find the distance to her grandparents as:

Hence, the distance fro Hayley's place to her grandparents is 5.7km
