In the figure below, ABC is dilated by factor of 7.5 resulting in DEF. if the area of ABC is 38 cm2, what is the area of DEF? ( figures are not drawn to scale.) Show your work.

Area of DEF=

The area of triangle DEF is 2137.5 cm²

Solution:

Given data:

Area of ABC = 38 cm²

Scale factor = 7.5

To find the area of DEF:

Area of dilated image = Area of original image × (scale factor)²

Area of DEF = 38 × (7.5)²

                    = 2137.5 cm²

Area of DEF = 2137.5 cm²

The area of triangle DEF is 2137.5 cm²

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
