Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of
, so the snow melted in x hours will be
.
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:

To find the depth of snow after 3 hours we will substitute
in our expression.



Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.
Answer:
f(9)=54
Step-by-step explanation:
Subsitute 9 for x in f(x)=6x

Tan(angle) = opposite/adjacent
tan(x) = 90/51
x = arctan(90/51)
x = 60.461217740442
which rounds to 60 when rounding to the nearest whole number
Answer: 60
