Answer:
{x,y}={−3,−1}
Step-by-step explanation:
Answer: 23 ft
Step-by-step explanation:
Suppose
h=height of street light
x=distance of woman from pole, 20-x=distance of man from pole
tan 24=x/h=0.445
tan 28=(20-x)/h=0.532
re-arranging the above we get:
x=0.445h
20-x=0.532h
thus the value of h will be given by:
20=0.977h
hence
h=20.5 ft
substituting the values we get:
x=woman's position =9.1 ft from the pole and the man is 10.9 ft away.

Answer:
Part a) 
Part b) 
Step-by-step explanation:
we know that
The original area of rectangle is equal to

so
if the length is increased by 6% and the width is by 15%
then
the new area is equal to
![A=[1.06(14)][1.15(9.5)]\ cm^{2}](https://tex.z-dn.net/?f=A%3D%5B1.06%2814%29%5D%5B1.15%289.5%29%5D%5C%20cm%5E%7B2%7D)


The new area is (1.219) times the original area
Part a) Calculate the percentage change in area of the rectangle

convert to percentage

Part b) what is the original area as a percentage of the increased area of the rectangle?
Divide the original area by the increased area

Convert to percentage
