Hello!
A(r) is a function. It takes a value of r, and from that calculates the value A. In this case, it takes the value of a radius, and <u>depending on what that value is</u>, it calculates the area.
A(3) would therefore represent the area based off of a radius of 3.
Hope this helps!
Answer:
Step-by-step explanation:
Using the rule of exponents
× = , then
× = =
Answer:
Equation of a line is y = mx + c
where m is the slope
c is the y intercept
From the graph using points ( 5 , - 4) and
( -5 , 2)
Slope = 2+4/ -5 - 5= 6/-10 = - 3/5
Equation of the line using point (5,-4) is
y + 4 = -3/5(x - 5)
y = -3/5x + 3 - 4
y = -3/5x - 1
Hope this helps
