Answer:
5 = 15/3 = 5/1.
Step-by-step explanation:
Multiply 5 by 3 to give the first number then 5 by 1 to give the second.
5 = 15/3 = 5/1.
The question gives you the formula to use, but it's printed wrong.
The 'x' is an exponent after the (1 + r).
All you have to do is take the formula, and write the numbers into it
that are also given.
The key thing to spot is that the forest is <u><em>decreasing</em></u>, so the 'r' is <u>negative</u>,
just as if you had money in a savings account and every year the bank took
6% <u>out</u> of it.
So the formula to use is f(x) = P (1 + r) ^x
P = 2000
r = -0.06
f(x) = 2000 (1 - 0.06)^x
= <em>2000 (0.94)^x</em>
The amount left after 12 years is
2000 (0.94)¹² =
2000 (0.476) =<em> 951.8 square kilometers</em>.

Step-by-step explanation:
Simplify ——————
3x - 1
Equation at the end of step 1 :
(6x - 1)
y - ———————— = 0
3x - 1
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using (3x-1) as the denominator :
y y • (3x - 1)
y = — = ————————————
1 (3x - 1)
Answer:
10
Step-by-step explanation:
15 = 1/2 * b * 3
15 * 2 = 3 * b
b = 30/3
b = 10 m
