By evaluating the quadratic function, we will see that the differential quotient is:
<h3>
How to get (f(2 + h) - f(2))/h?</h3>
Here we have the quadratic function:
Evaluating the quadratic equation we get:
So we need to replace the x-variable by "2 + h" and "2" respectively.
Replacing the function in the differential quotient:
If we simplify that last fraction, we get:
The third option is the correct one, the differential quotient is equal to 8 + 4.

Answer:
The area of the sector is 3pi/2
Step-by-step explanation:
A sector is that part of a circle bounded by 2 radii and an arc
The circle has an area of 9 pi with a central angle of 60 degrees.
Now the area of the sector is pretty much straight forward to calculate. Since it is a circle, the total angle we have is 360.
Now the sector subtends an angle of 60 degrees at the centre. What this means is that the sector is exactly 1/6 of the circle. meaning that cutting the circle into 6 slices will give the sector.
Thus, the area of the sector is one-sixth the area of the circle.
The area of the sector is thus 1/6 * 9pi = 9pi/6 = 3pi/2 or 3/2 pi
Answer:
1. 7
2. 48
Step-by-step explanation:
you have to <u>subtract</u> 49-42 because some got taken away then you should end up with 7, 63-15 is 48.
