Let x be the width , then the height = 4x
Area of this right triangle is x(4x)/2
Area = 4x²/2 = 32 m²
x² = 16
x = 4 m. If the width is 4 m, the height = 4 x 4 = 16 m
Answer: |√9/16| = ¾ or .75

Answer:
$17.14
Step-by-step explanation:
Given : 
To Find : Using the quadratic regression equation, what was the predicted profit in year 8
Solution :

Where y is profit and x is year
Substitute x = 8


So, Option D is true
Hence the predicted profit in year 8 is $17.14
Answer:
Step-by-step explanation:
let : x The length and y the width you have this system :
xy =60....(1)
x = y+10...(2)
put the value for x in (1): (y+10)y =60
the quadratic equation is : y² +10y - 60 = 0
Δ =b² - 4ac a = 1 b= 10 c= - 60
Δ =10² - 4(1)(-60) = 324 =18²
y 1 = (-10-18)/2 negatif...... refused
y 2 = (-10+18)/2 =4
the width is 4
Answer:
Average weight
