Calculating
the value of f(x) for the given interval.
For x = -
4, f(x) = f(- 4) = (- 4)^2 + 2 (- 4) + 3 = 11
For x =
6, f(x) = f(6) = (6)^2 + 2 (6) + 3 = 51
Now using
formula for the calculation of average rate of change of f(x) over the given
interval of [- 4, 6];
(f(b) –
f(a)) / b – a = (f(6) – f(- 4)) / 6 – (- 4) = (51 -11) / 10 = 4
<span>So option “E” is
correct.</span>
Sally types faster than sue per minute by 10 words. If you divide 3000 by 60 because there are 60 minutes in an hour you will get how many words she types a minute which would be 50.
Number ten is 60 73+36=108
Answer:
7. 75.36 inches
8. 21 inches
9. 13 inches
Step-by-step explanation:
7. <em>Circumference = π × d</em>
The diameter would be two times the radius, or 2 × 12 = 24. So, circumference would be 3.14 × 24 = 75.36 inches.
8. <em>Circumference = π × d</em>
If we move variables around, <em>d = Circumference / π</em>
So, d = 65.94 / 3.14 = 21 inches.
9. To do this, let's figure out the diameter: <em>d = Circumference / π</em>
d = 81.64 / 3.14 = 26. Now the diameter is two times the radius, so to get the length of the radius, we must divide the diameter in half. 26 / 2 = 13 inches.
