Answer:
132
Step-by-step explanation:
We use the volume formula for a cylinder which is V=πr2h, divide the diameter by 2 to get the radius and fill in our formula to get 131.88, finally round to 132.
Answer:
a)
Completing the square
b)
You can prove that is always positive, stating;
The sum of two squared numbers can't be negative. Hence is always positive.
Also, if we take the discriminant of
Once the discriminant is negative, the quadratic has no real root. So, the function never touches the real axis and the function lies above or below the real axis. If we take x as 0, y = 20, therefore, the function lies above the real axis. It is always positive.
Answer:
3x+3=-36 is the equation
The answer is -13,-12,-11
Step-by-step explanation:
So consecutive integers, so lets say it’s x, if it’s consective it means the next number after, (Ex: 1,2,3,4,5) so the pattern is x+x+1+x+2 and so on. In this a
cade it’s 3 numbers so x+x+1+x+2 which is 3x+3.
Were trying to find -36 so 3x+3=-36
Solve the equation and you’ll get -13.
Add 1 to -13 and add 2 to -13 and you have your 3 consecutive numbers!
-13+1=-12 -13+2=-11. The original is -13
check: -13+-12+-11=-36 is correct
The equation is
3x+3=-36
