Answer:
<h2>Area in Hectares = 16.2 hectares</h2>
Step-by-step explanation:
Area of a rectangle: length × width
A = 600 × 270
A = 162,000 meters
162,000 meters ⇒ 16.2 hectares
Answer:
The answer you put is correct.
Step-by-step explanation:
It is B.
Answer:
all work is shown and pictured
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>
C
Expiation:
If x=6 and y=1, then 3y=3 and 1/2x=3. They are equal.
