The area of a trapezoid is 96 m. If the two bases measure 11m and 13m, solve for the height.

Step-by-step explanation:

Formula

Area = 1/2 (b1 + b2)*h

Givens

b1 = 11 m

b2 = 13 m

Area = 96

h = ?

Solution

96 = 1/2 (11 + 13) * h      Multiply by 2     Combine the bases as well.

96*2 = (24) * h              Divide by 24

96*2/24 = h                  Multiply by 2 and divide by 24

h = 8

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

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,
