Answer:
A. 11
Step-by-step explanation:
The average rate of change of the given function over the interval [2,6] is simply the slope of the secant line connecting the point (2,f(2)) and (6,f(6)).
This implies that, the average rate of change over [2,6]
From the table f(6)=71
Since we want the average rate of change to be 15, we have;
This implies that;
The correct choice is A.
Answer:
The radius of the circle is 9 in
Choice C is correct
Step-by-step explanation:
254.4696 square inches. Whats the radius of the circle (use pie=3.1416.
The area of a circle with radius r is given as;
We substitute the given area and the value of pi given to solve for the radius;
Answer:
26 + 22i
Step-by-step explanation:
Given
(2 + 4i)(7 - 3i) ← expand product using FOIL
= 14 - 6i + 28i - 12i² ← i² = - 1
= 14 + 22i + 12
= 26 + 22i ← in standard form
Answer:
x = sqrt(17)/8 - 1/8 or x = -1/8 - sqrt(17)/8
Step-by-step explanation using the quadratic formula:
Solve for x over the real numbers:
4 x^2 + x - 1 = 0
Divide both sides by 4:
x^2 + x/4 - 1/4 = 0
Add 1/4 to both sides:
x^2 + x/4 = 1/4
Add 1/64 to both sides:
x^2 + x/4 + 1/64 = 17/64
Write the left hand side as a square:
(x + 1/8)^2 = 17/64
Take the square root of both sides:
x + 1/8 = sqrt(17)/8 or x + 1/8 = -sqrt(17)/8
Subtract 1/8 from both sides:
x = sqrt(17)/8 - 1/8 or x + 1/8 = -sqrt(17)/8
Subtract 1/8 from both sides:
Answer: x = sqrt(17)/8 - 1/8 or x = -1/8 - sqrt(17)/8
Answer: C
