A state park uses a histogram to record the heights of various trees. Suppose three of the trees increase in height from 66 inches to 79 inches over a period of 2 years. Which bars will change on the histogram?

the square root of what number? if you add that, then someone will probably answer the question.

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

the radius is 2 times the diameter.
