The answer to this is 229.183°
Answer:
f(12) = - 20
Step-by-step explanation:
To evaluate f(12), substitute x = 12 into f(x), that is
f(12) = - 2(12) + 4 = - 24 + 4 = - 20
Step-by-step explanation:
as a whole number = 5
You will need to work left to right.
p - 10p + -5p +14p - -9p - 2 = -20
-9p + -5p +14p - -9p - 2 = -20
-14p +14p - -9p - 2 = -20
0p- -9p - 2 = -20
9p - 2 = -20
Then you will want to eliminate 2 by adding it to both sides
9p = -18
Then divide by 9 to isolate P
p=-2
Answer:
Step-by-step explanation:
Radius of outer circle = R = 9 cm
Radius of inner circle = r = 5 cm
Area of the shaded region = area of the outer circle - area of the inner circle.
= πR² - πr²
= π(R² - r²) = 3.14*(9² - 5²)
= 3.14 * (81- 25) = 3.14 * 56
= 175.84 cm²
