Answer:
r= 20.48
Step-by-step explanation:
To find the radius of you know the volume, divide both sides of the equation and then evaluate the right side, then take the cube root to find r
(pleaseee tell me if I'm wrong)
It’s already written in the appropriate format.
The quadratic function given to us is:
We are asked to find the vertex form of the function.
The general formula for the vertex form of a quadratic equation is:
In order to write the function in its vertex form, we need to perform a couple of operations on the function.
1. Add and subtract the square of the half of the coefficient of x to the function.
2. Factor out the function with its repeated roots and re-write the equation.
Now, let us solve.
1. Add and subtract the square of the half of the coefficient of x to the function.
2. Factor out the function with its repeated roots and re-write the equation.
Therefore, we can conclude that the Equation and vertex of the equation is:
Answer:
C
Step-by-step explanation:
To determine which point is a solution substitute the coordinates into both inequalities and check validity
A (2, 0 )
2 + 0 = 2 ← not greater than 2
(4 × 2) + 0 = 8 > - 1
The point (2, 0) is not a solution as it does not satisfy the first inequality
B (0, 2 )
0 + 2 = 2 ← not greater than 2
0 + 2 = 2 > - 1
The point (0, 2) is not a solution as it does not satisfy the first inequality
C (0, 3 )
0 + 3 = 3 > 2
0 + 3 = 3 > - 1
The point (0, 3) satisfies both inequalities and is therefore a solution
Answer:
Step-by-step explanation:
Simplify -12\ 4−12÷4 to -3−3.
-3=-3-8-48,3
−3=−3−8−48,3
2 Simplify -3-8−3−8 to -11−11.
-3=-11-48,3
−3=−11−48,3
3 Simplify -11-48−11−48 to -59−59.
-3=-59,3
−3=−59,3
4 Since -3=-59,3−3=−59,3 is false, there is no solution.
