Karen wanted to measure the height of her school's flagpole. She placed a mirror on the ground 44 ft from the flagpole, and then

walked backward until she was able to see the top of the pole in the mirror. Her eyes were 5 ft above the ground and she was 12 ft from the mirror. Using similar triangles, find the height of the flagpole to the nearest hundredth of a foot.

What is the approximate distance between the points (-3,-4)(-8,1) on a coordinate grid?
Alex

\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-3}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{-8}~,~\stackrel{y_2}{1})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[-8-(-3)]^2+[1-(-4)]^2}\implies d=\sqrt{(-8+3)^2+(1+4)^2} \\\\\\ d=\sqrt{25+25}\implies d=\sqrt{50}\implies d\approx 7.071

Box A has a volume of 12 cubic meters. Box B is similar to box A. To create box B, box A's dimensions were multiplied by five. W
cestrela7 [59]

The formula for the volume of a box (assuming that it is in the shape of a cube) is <u>V=B^3</u>.

12=B^3

Now, do the cube root of 12 to find each dimension, all dimensions will be equal as it is a cube.

B= about 2.29 (when doing on a calculator keep full answer and do not round)

Now to find the volume of box B, multiply each dimension by 5

5(2.29...) times 5(2.29...) times 5(2.29...)

=1,500 m^3

Hope this helps!
