M and N are equilateral triangles. The scale factor of M to N is 8 : 4.1 and the area of triangle M is 320 square inche. find the area of triangle N

84.05 square inches

Step-by-step explanation:

Given;

Area of M = 320 square inches

Scale factor of M to N = 8 : 4.1

Since M and N are equilateral, it means all 3 sides in triangle M are equal and all 3 sides in triangle N are equal

To find the area of triangle N, we have:

= 84.05 square inches

Therefore area of triangle N =

84.05 square inches

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
