<span>As we know
cos theta-1= 0
cos theta = 1
Now Look at a graph of the cosine function
, and you will observe that cos theta = 1
at the points X = 0, and X = 2pi
hope it helps</span>
The formula is (x1+x2)/2 will give you the x of the mid point.
(y1+y2)/2 will give you the y of the mid point.
So, (3+9)/2= 6
And (6+8)/2=7
The mid point is (6:7)
Answer:
(a) rate of change = 8
(b) Function: y = 8x
(c) Domain: 0 ≤ x ≤ 2
Range: 0 ≤ y ≤ 16
Explanation:
Looks like a inverse variation sequence.
Inverse Variation formula: y = k(x)
Take two points: (1, 8), (2, 16)
Find the value of k which is constant also considered as <u>rate of change</u>.
<u>Insert values</u>:
===========
Equation: y = 8x
Domain lies in the x axis, Range lies in the y axis.
The answer you are looking for is 8.3%.
To find this, you must find out how many students did not choose to voice their opinions. Simply add 17 and 5 to get 22, and subtract 22 from 24. This will give you 2 students who didn't voice their opinions. Then, divide 2 by 24. In doing so, you'll get 0.083333... which you multiply by 100 to get a percent. You'll be left with 8.3333... which rounded to the nearest tenth, is 8.3%.
I hope this helps!
