Answer:
A.
Step-by-step explanation:
For starters, we can combine like terms. we can combine -3 with -2 to get -5, and with
to get
. Now, we have
as our final answer, or answer A. Also, brainliest is not necessary. Hope this helps!
To find this, we need to find the Surface area of the lateral surface of the cone (without the circle base).
Now we just need to plug what we know into the equation
Wither you can keep your answer in pi or take it out of pi, depending on what the requirements are.
To take it out of pi you need to multiply 6 by pi (remembering to use 3.14 as pi in most cases since that is what is generally accepted on tests and exams).
Then rounding to the nearest square inch which would mean that the amount of paper needed is =19in²

very interesting
the equation we are given is for when the units of t are in years
I do know that you want to have the variable as time, but I'm not sure if you want it in years or months
I will solve for in months because that makes more sense
in that case, it will be 2250(1+r)^m where r=monthly interest rate and m=time in months
to compare, we can do
when 1 year has elapsed, t=1 and m=12
and the amount earned should be the same
so therfor we can say
divide both sides by 2250 to make it easier
take 12th root of both sides
minus 1 both sides
using a calculator
-1+1.01316961=r
<span>0.01316961=r</span>
<span>not sure if yu want percent to thousandth or decimal to thousandth</span>
<span>if decimal then 0.013 is interest rate</span>
<span>if percent then it is 1.317% interest rate</span>
