Trina and Jessie went on a vacation to Hawaii. Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level. Jessie went hang-gliding and reached an altitude of 87.9 meters, which is above sea level. Who is closer to the surface of the ocean?

Step-by-step explanation:

LEt the surface of the ocean be at the zero level i.e at 0metres

If Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level, the distance between Trina and the sea level will be:

D = 0-(-85.6)

D = 0+85.6

D = 85.6m

If Jessie went hang-gliding and reached an altitude of 87.9 meters, the distance between Jessie and the sea level will be:

D = 87.9-0

D = 87.9m

Since the distance of Trina is less than that of Jessie, this means that Trina is closer to the surface of the ocean

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
