Answer: Assume c = 0

Step-by-step explanation:

Step-by-step explanation:

Assume c = 0

Using the formula for the x-coordinate of the vertex, b can be calculated in terms of a:

B can then be substituted into the quadratic equation, along with the coordinates of the vertex, to solve a:

AND

Substituting into the quadratic equation:

Last season a Major League Baseball player got 160 hits in 200 times at bat. If the player expects to bat 400 times in the entir
zimovet [89]

Answer:

He's expected to hit 320 times.

Step-by-step explanation:

To solve this problem we first need to compute the ratio at which he hit the ball in the last season, to do that we need to divide the number of hits by the number of tries. We have:

ratio = number of hits/ number of tries

ratio = 160/200 = 0.8

Since he's expected to bat 400 times if he maintains the same ratio in this season he'll hit:

number of hits = (number of tries)*ratio

number of hits = 400*0.8 = 320

He's expected to hit 320 times.
