A scuba diver dove down from a surface of the ocean to an elevation of -59 9/10 feet to a rate of -16 feet per minute. After spending 11.75 minutes at that elevation the diver ascended to an elevation of -28 9/10 feet . The total time for the dive so far was 18 1/8 minutes. What was the rate of change in the divers elevation during ascent? Round your answer to the nearest hundredth. The rate changed of the divers elevation was ft/min

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

a. she will receive a refund of $278.

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
