Answer:
You are probably making this harder than it is. That's what I was doing. So it is asking for the hour when it is 
. So that would be 4. Then it is asking for the temperature at 2 hrs. so that would be 104
. so your answer would be 104, 4.
Hope this helps!
Answer:
Step-by-step explanation:
Domain= All real numbers. To get this answer i just plug the x-values into the quadratic formula to get the y-output.
Maximum area=1323/8
Range= y<= 1323/8
Area of a circle = πr²
Radius = 18/2 = 9
A = (3.14)(9)²
A = 254.34
Hope this helps :)
Answer:
Correct option is
B
1.x+0.y=7
x=7 can be written as, 1.x+0.y=7 as the coefficient of x is 1 and that of y is 0. Step-by-step explanation:
Combine like terms
-7y² + 6y² - 2y² = -3y²
4y + (-5y) - (-9y) = 4y - 5y + 9y = 8y
9 + 9 - (-2) = 9 + 9 + 2 = 20
-3y² + 8y + 20 is your answer
hope this helps
