Answer:
The answer is C) 4x + 8y +27.
Trial and error aren't necessary.
Increasing 12% per month means that at any time,
there are (1.12) x (the number there were a month earlier).
After, say, 'M' months, the number has grown by (1.12)^M power.
We want to know what 'M' has to be so that 50(1.12)^M = 1,000
Divide each side by 50 : (1.12)^M = 20
Take the log of each side: M log(1.12) = log(20)
Divide each side by log(1.12): M = log(20) / log(1.12)
<em> M =</em> 1.301 / 0.0492 = <em>26.44 months</em>
Answer:
4/9
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
4xy(y^2 + 2x) Remove the brackets (distributive law)
4xy^3 + 8x^2y
You have to turn the two terms around to see the correct answer. That's perfectly alright when dealing with addition of pluses.
8x^2y + 4xy^3
Answer:
0,1
Step-by-step explanation:
Let n represent the first interger. and n+1 represent the next interger.
Complete the square.
Take the square root.
Plug 0 in for 0+1.
So the consective intergers are 0,1.
