Answer:
See the attachment. (All results are integers, so are correct to 6 decimal places.)
Step-by-step explanation:
The function simplifies to ...
... f(x) = x(x-9)/((x+1)(x-9))
... f(x) = x/(x+1) . . . for x ≠ 9
Answer:
25,886.01 in²
Step-by-step explanation:
The area of shaded region = Area of the outter circle (the larger circle) - area of the inner circle (the smaller circle)
Area of a circle = πr²
Radius of larger circle = PO = 93.4 in
Area of the larger circle = 3.14*93.4² = 27,391.98 in²
Radius of smaller circle = PO - RQ = 93.4 - 71.5 = 21.9
Area of smaller circle = 3.14*21.9² = 1,505.97 in²
Area of shaded region = 27,391.98 - 1,505.97 = 25,886.01 in²
Answer
26√2
Step-by-step explanation:
The trick here lies in recognizing that both 18 and 32 have factors that are perfect squares: 18 = 2*9 and 32 = 2*16. Therefore, we can write
2sqrt18 as 2√2√9, or 6√2, and 5sqrt32 as 5√2√16, or 20√2.
Then the original expression, in simplest form, is 6√2 + 20√2, or 26√2
The answer is a . hope it helps
