The function h is defined as follows.

JulsSmile [24]

Answer:

The equation you are given is a quadratic. The standard form of a quadratic is y = a(x-h)2 + k where (h,k) is the vertex of the graph, which is a parabola. Vertically moving the graph 4 units upward means that you are moving k +4 units.

y = a(x-h)2 + k standard form

y = 5x2 - 4 original equation

y = 5(x-0)2 - 4 re-written in standard form

h = 0 k = -4

Four (4) units up is k + 4--->-4 + 4 = 0.

Therefore, f(x) = 5x2 + 0--->f(x) = 5x2.

In Class 1, what is the median score? A) 70 B) 70.5 C) 71.5 D) 72

evablogger [386]

Answer:

B) 70.5

Step-by-step explanation:

Median = middle value when the values are placed in order.

If there are two middle values, the median is the mean of those two values.

Class 1

45 46 51 52 53 53 61 63 64 65 66 68 70 70 71 73 76 77 79 81 82 83 84 87 90 92 93 95

There are 28 values in Class 1.

Therefore, there are two middle values: 14th and 15th values

14th value = 70

15th value = 71

$\implies \textsf{Median}=\dfrac{70+71}{2}=70.5$
