Answer:
( 8 , - 8) => x² - 55 = 9
( 4 , - 4) => 2x² - 32 = 0
(5 , - 5) => 4x² - 100 = 0
(11 , - 11) => x² - 140 = -19
( 3, - 3) => 2x² - 18 = 0
Step-by-step explanation:
1)
x = ( 4 , - 4)
2)
x = ( 5 , - 5 )
3)
x= ( 8 , - 8)
4)
x = ( 11 , -11)
5)
x = ( 3 , - 3)
The area means to multiply the length by the width.
let's solve.
14 1/2 x 13 1/4.
convert our fractions into decimals.
14 1/2 = 14.50
13 1/4 = 13.25
Now we can multiply properly.
14.50 x 13.25 = 192.125
since our shape is 2-Dimensional, our units are ^2.
Your area is:
192.25 ft^2

Using similarity principle, the height of the tree is 1.97 meters
<h3>How to find height of the tree?</h3>
He is 1.75 meters tall.
His shadow = 33.7 meters
The length of the tree shadows = 37.95 meters
Using similarity principles where the corresponding length are a ratio of each other.
Therefore,
1.75 / x = 33.7 / 37.95
cross multiply
37.95 × 1.75 = 33.7x
66.4125 = 33.7x
divide both sides by 33.7
x = 66.4125 / 33.7
x = 1.97069732938
x = 1.97 meters
