Answer:
V = 486, or approx. 1,526.814
Step-by-step explanation:
V = *r²*(h/3)
plug in the numbers: V = * (9)² * (18/3)
simplify: V = * 81 * 6
simplify: V = 486, or approx. 1,526.814
Answer: 42.25 feet
Step-by-step explanation:
We know that after "t" seconds, its height "h" in feet is given by this function:
The maximum height is the y-coordinate of the vertex of the parabola. Then, we can use the following formula to find the corresponding value of "t" (which is the x-coordinate of the vertex):
In this case:
Substituting values, we get :
Substituting this value into the function to find the maximum height the ball will reach, we get:
Answer:
Each part is 3.5 inches long.
Step-by-step explanation:
The ruler has a length of 7-inches, so when you want to split it directly in half, you divide 7/2. This is the number 3.5 inches. On the ruler you can see when looking at the first segment that it goes from 0 inches to half-way between 3 inches and 4 inches, which is 3.5 inches.
Step-by-step explanation:
7(4x + 9) - 4
= (7 × 4x) + (7 × 9) - 4
= 28x + 63 - 4
= <u>28x + 59</u>
So, 7(4x + 9) - 4 is equivalent to 28x + 59 (D)
