Consider the graph and the equation of function f. F(x)=2sin(1/2x) + 1
What is the midline of the function?

A. Y=4pi
B. Y=2
C. Y=0
D. Y=1

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Ascatter plot with a trend line is shown below. which equation best represents the given data? y = x + 2 y = x + 5 y = 2x + 5

Compare the following pair of numbers a and b in three ways. a. find the ratio of a to b. b. find the ratio of b to a. c. complete the sentence: a is percent of b. a=120 and b=340 a. the ratio of a to b is . b. the ratio of b to a is . c. a is nothing percent of b.
