I need help, please and thank you. I know that you have to multiply the diameter by 2 to find the radius, but with the 9 pi, it
andrew11 [14]

Answer:

r=6

Step-by-step explanation:

The area of a circle is given by πr². Note that this uses the radius, not the diameter.

Now, one quarter of this area (ABC) is given to be 9π.

So apparently:

\frac14 \pi r^2 = 9\pi

If you solve this:

\frac14 r^2 = 9 (divide both sides by π)

r^2 = 9\cdot4 (multiply both sides by 4)

so

r = √36 = 6

so the radius is 6.

Part V: If −1 is one of the roots of H(x) = x3 − 7x2 − x + 7, use synthetic division to find the resulting quadratic expression.
Alekssandra [29.7K]
Solve for x over the real numbers:
x^3 - 7 x^2 - x + 7 = 0
The left hand side factors into a product with three terms:
(x - 7) (x - 1) (x + 1) = 0
Split into three equations:
x - 7 = 0 or x - 1 = 0 or x + 1 = 0
Add 7 to both sides:
x = 7 or x - 1 = 0 or x + 1 = 0
Add 1 to both sides:
x = 7 or x = 1 or x + 1 = 0
Subtract 1 from both sides:
Answer:  x = 7 or x = 1 or x = -1

Determine the larger of two consecutive integers whose sum add to 85
Vesnalui [34]
N+(n+1) = 85. 2n+1=85, 2n=84. n=42. So the consecutive integers are 42 and 43, and the larger one is 43.
