Answer:
58
Step-by-step explanation:
The marked points on the graph show that the number of hot cocoas sold decreases by 6 when the temperature goes up by 6 degrees. That is, the line has a slope of -1. The y-intercept is 100, so the equation of the line can be written as ...
y = mx +b . . . . . line with slope m and y-intercept b
y = -x +100
Then for x = 42, the expected value of y is ...
y = -42 +100 = 58
Mei Mei can expect to sell 58 hot cocoas on a day when the high is 42°F.

π x 52^2 = 8494.866535
3 SF = 849
Answer: 3^2
Step-by-step explanation:
remember logb a=n <---> a=b^n
so therefor the answer is log3 9=2 ---> 9 = 3^2
