Answer: i dont know the answer right now but i know how to find it
Step-by-step explanation:
multiply 272.5 by 1,000
Answer:
C
Step-by-step explanation
This has a factor of 6% or 0.06. But, you are adding and not subtracting so it is 1.06. ( If you multiply by a number less than 1 then it is actually dividing) So C is the only on that is correct.
As far a domain, you only care about the denominator and radicals.
f(x) = 2 - √x is the denominator, so it can't be 0.
Also x is under a radical, so x can't be negative.
Set the denominator equal to 0 to find the excluded values.
2 - √x = 0
-√x = -2
√x = 2
x = 4, so 4 is an excluded value
The domain is all real numbers greater than or equal to 0, except 4.
[0, 4) U (4, ∞)
0 ≤ x < 4 U x > 4
Take any 2 points, so we'll us (2,16) and (4,32)
then do y2-y1/x2-x1
so 32-16=16
4-2×2
so then do rise(y) over run(x)
so the slope is 16/2 which simplifies to 8
so the rate of change is
y=8x
