Answer:
c. 8 units
Step-by-step explanation:
You are to find the y-intercepts of the two functions given, then report the difference between them. The y-intercept is the y-value when x=0.
For f(x), we have ...
f(0) = 3·2^0 = 3·1 = 3
__
For the table, we can see that x=0 is halfway between x=-2 and x=2, so the y-intercept can be expected to be halfway between y=3 and y=-13. That value for y is ...
g(0) = (3 + (-13))/2 = -10/2 = -5
That is, the y-intercept of g(x) is -5.
__
The difference between f(0) and g(0) is ...
f(0) -g(0) = 3 -(-5) = 8 . . . . units
Answer:
The question mark is just there in place of a number it is telling you that it does not have a number there and you have to solve for it. I hope this helps if not i can explain it more
Step-by-step explanation:
Answer:
20π
Step-by-step explanation:
Area = πr^2
100π = πr^2
solve for r and r = 10
circumference of a circle is 2πr
therefore 2π×10=20π in
Answer:
8 units because the diameter is the side to side length of the circle so when you count it you get 8 units.
