Answer:
15 feet.
Step-by-step explanation:
We have been given that the path of a diver is modeled by , where f(x) is the height (in feet) and x is the horizontal distance (in feet) from the end of the diving board. We are asked to find the maximum height of the diver.
Since our given function is downward opening parabola, so its maximum point will be vertex.
To find maximum height of the diver, we need to figure out y-coordinate of vertex.
First of all, we will fund x-coordinate of vertex using formula as:
Let us find y-coordinate of vertex by substituting in the given function as:
Therefore, the maximum height of the diver is 15 feet.
Answer:
C. 490.
Step-by-step explanation:
25% = 0.25.
If the number of emails that Ryan and Taylor each received is x emails then Sara received 2x + 0.25 * 2x = 2.5 emails.
So 2x + 2.5x = 882
x = 882/4.5
x = 196.
So Sara received 2.5 * 196
= 490 emails.

EXPLANATION
To write in the form , we have to complete the squares.
We add and subtract half the coefficient of square.
The first three terms of the function is now a perfect square.
We now simplify rto obtain,
