A window is in a shape of an isosceles trapezoid and has an area of 24 square feet. It is 4 feet high and 8 feet wide at the bottom. How wide is the window on top?

4feet

Step-by-step explanation:

Area of the trapezoid = 1/2(a+b)h

a and b are the sides

h is the height

Substitute the given values

Area of the trapezoid = 1/2(8+b)*4

24 = 1/2(8+b)*4

2(24) = (8+b) * 4

48 = 32 + 4b

4b = 48-32

4b = 16

b = 16/4

b = 4feet

Hence the window on top is 4feet wide

If we let x as the number of years of service in the company and f(x) as the increase in the wage, the step wise function that describes the scenario isf(x) = { 0.5,   x < 3          { 1.0,   3  ≤ x < 6          { 1.5,   6  ≤ x < 9          { 2.0,   9  ≤ x < 12the point (2, 12) represents the wage increase of x < 12im not sure thobut hope this ☺
