Answer:
34.45
Step-by-step explanation:
11÷2 = 5.5
so 5.5x5.30 = 29.15 + 5.30 = 34.45
Y=5x
Explanation:
You would take two points and use the slope formula
Y2-y1/x2-x1
So I took the points (0,0) and (1,5)
5-0/1-0
5/1
5= the slope
So now we know y=5x+b and since it shows us on the graph where the line crosses the y axis we know the y intercept will be zero because it crosses at 0. When the y-intercept is 0 we don’t even need to list it.
Area (a) as a function of radius (r) might be written
a(r) = πr²
