during a 7 hour snowstorm it snows at a rate of 1 inch per hour for the first 2 hours, at a rate of 2 inches per hour four the next four hours and at rate of 1 inch per hour for the final hour. Write a piece wise function that gives the depth of the snow during the snowstorm.

9 inches of snow fell in the 7-hour snowstorm.

Step-by-step explanation:

To find your answer write an equation to find your answer.

1 inch per hour for two hours 1(2)

2 inches per hour for four hours 4(2)

and 1 inch in the last hour

so add those up

1(2)+4(2)+1

2+8+1

9

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
