f(x) = 2x^2 - x - 10
Part A:
x-intercepts: (-2,0), (5/2,0)
Part B:
The vertex is the minimum
vertex: (1/4, -81/8)
Part C:
A:
x: -2, -1, 1/4, 1, 2
y: 0, -7, -81/8, -9, -4
B:
The answer would be that Mario finished his homework at 3:55
10/16 because you multiply 8x2 to get sixteen, the denominator you need. So whatever you do to the denominator, you do to the numerator. So 5x2 is 10. 10/16
This is the concept of geometry, the total sum of angles in a hexagon is given by:
(n-2)*180
=(6-2)*180
=720
the size of each interior angle will be:
120°
N/B
the exterior and interior angles are supplementary to each other.
Therefore the size of the exterior angle will be:
180-120
=60°
the answer is A
For this case we have the following expression:

We must find the value of the expression when:

Substituting we have:

Finally, the value of the expression is:
