Answer:
1) 18 inches
Step-by-step explanation:
By the Midsegment Theorem: A midsegment connecting two sides of a triangle is parallel to the third side and is half as long the third side.
ans: 36/2 = 18
- Question -
Bananas are $0.59 a pound. How much will 25 pounds of bananas cost?
- Answer -
$2.95
- Explanation -
$0.59 * 5 = $2.95
The general form of sine curve is f(x) = a sin (nx)
Where: a is the amplitude and n = 2π/period
Given the points of the sine curve which is
(0, 0) and (160, 1) and (320, 0) and (480, -1) and (640, 0)
the maximum value of f(x) = 1 , and the minimum value of f(x) = -1
∴ amplitude = a =1
And the function complates one cycle from 0 to 640
∴ period = 640 ⇒⇒⇒ n = 2π/640 = π/320
∴ f(x) = 1 * sin (π/320)x = sin (π/320)x
∴ The correct answer is option d
<span>d) f(x) = sin pi over 320x</span>
