1) Since an increase of 25% represents an increase of 1/4 of the whole.
2) And we have 4/5, increasing 1/4 we'll write:

3) So representing in the diagram an increase of 25% would be:
x =4/5
x(1.25) =y
4/5(1.25) =1
what is shown on the graph is a function
Answer:
I cant see the pic
Step-by-step explanation:
Two of the given points have the same y-value. The midpoint of those two will be on the line of symmetry, as is the vertex. The x-value there is (-1+5)/2 = 2.
<span>A = 2 * (0.5ab) + b (10 - a) = ab + 10b - ab = 10b
10b = 30√2; b = 3√2
sin α = 3√2 / 6; α = 45 degrees
Small angle: 45°; Large angle: 135°</span><span>
