Answer:
height of the tree is 30 feet
Step-by-step explanation:
a tree casts a shadow 42 feet long . at the same time, a person 5 feet tall casts a shadow 7 feet long.
shadow of a 5 feet tall person is 7 feet long
Let x be the height of the tree
shadow of a 42 feet tree is x feet long
Make a proportion
![\frac{x}{42} =\frac{5}{7}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B42%7D%20%3D%5Cfrac%7B5%7D%7B7%7D)
cross multiply
![7x=(42)(5)](https://tex.z-dn.net/?f=7x%3D%2842%29%285%29)
![7x=210](https://tex.z-dn.net/?f=7x%3D210)
divide by 7 on both sides
x=30
So height of the tree is 30 feet
Answer:
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
Step-by-step explanation:
Parallel lines have same slopes.
Line 1, L1: 5x-2y=20 is in standard form Ax+By=C therefore slope m1= -A/B = -5/-2 = 5/2 or you can solve it for y so you will have the equation in slope-intercept form.
5x-2y = 20
-2y = -5x+20
y = (-5/-2)x+20/(-2)
y = (5/2)x-10 hence m1=5/2 and y-intercept is -10
Line 2 , L2: y-y1 = m (x-x1), m=m2=m1=5/2
Point p(5,0) or p(x1,y1) therefore x1=5 , y1=0 and m=5/2
L2: y-0 = 5/2(x-5)
y = 5/2x-25/2
8 x 1.25 = 10
10 x 10 = 100
