Step-by-step explanation:
Using the table of values you could graph the parabola, with coordinates.
Hope this helps.
B.
Rational is defined as being able to write it as a fraction. 2.22/ 2 = 1.11 which is 1 11/100
It is 5/40. If you divide 5/40 by 5 on each side then it will equal to 1/8
Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Rewrite in the standard form:</u>
- f(x) = - 0.0033x² + 0.84x
<u>The maximum height is the vertex with x- coordinate -b/2a, which is:</u>
- x = -0.84/2(-0.0033) ≈ 127.27
<u>The highest point is:</u>
- f(127.27) = -0.0033(127.27)² + 0.84(127.27) ≈ 53.45 m
<u>The horizontal distance the golf ball travels before hitting the ground:</u>
- f(x) = 0
- - 0.0033x² + 0.84x = 0
- 33x² - 8400x = 0
- x(33x - 8400) = 0
- x = 0- initial point
- 33x = 8400 ⇒ x = 8400/33 ≈ 254.55 m
Answer:
187.5 doughnuts (about 188)
62.5 candy bars (about 63)
Step-by-step explanation:
So the proportion of middle schoolers who prefer doughnuts is p = 9/12. That means the proportion of middle schoolers who prefer candy is 1 - 9/12 = 3/12.
The number of middle schoolers is n = 250.
Let X represent the number of doughnuts you need. The expected number is E(X) = np, so multiply them together:
E(X) = np
E(X) = 250 * 9/12 = 187.5 doughnuts
Let Y represent the number of candy bars you need. The expected number is E(Y) = np, so multiply them together:
E(Y) = np
E(Y) = 250 * 3/12 = 62.5 candy bars
