Answer:
y = 1/5x - 7/5
Step-by-step explanation:
y = 1/5x + b
-1 = 1/5(2) + b
-1 = 2/5 + b
-7/5 = b
Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29
Answer: 408.2 ft^2
Step-by-step explanation:
A=2πrh+2πr2
A=2(3.14)(5)(8)+2(3.14)(5)^2
A=6.28*40+6.28*25
A=251.2+157
A=408.2 ft^2
First, we know the formula to find the area of a square is A=s^2 where s= side length. Since we have the area, we can solve for s: 81=s^2. To solve for s, you would take the square root of both sides to get s=9. Then, we know the formula for the perimeter of a square is P=s*4. Since we now have s, we can solve for P: P=9*4 or P=36 feet which is the final answer.
