The slope formula:
m - a slopeb - y-intercept
We have:
and point
Substitute:
Answer: A.
Answer:
729
Step-by-step explanation:
1/3^-2×3^-4×(-1)^2
=3^2×3^4/1
=9×81
=729
The functions in part A are correct, we will now use them to solve for part B.
We equate the numbers of the trees in order to find x, which the number of years after which they will be equal.
800(0.95)ˣ = 50(1.15)ˣ
40 = (1.15 / .95)ˣ
Taking log₁₀ on both sides,
log(40) = x*log(1.15/0.95)
x = 19.31 years
Answer:
Your answer is C.
Step-by-step explanation:
take 2/5 x 240 = 96 which is two fifths of 240
Hope this helps. :)
Have a good day!
