Step-by-step explanation:
The above given expression "72t+8 " have to be factorized by the following methods.
<u>Step 1 : </u>
First we must check both numbers in order to obtain common factor for both ,for this equation "8" is the common factor for both .
<u>Step 2:</u>
After obtaining the common factor for the equation equation, we must now take the factor as common outside the bracket and form the equation as follows,
⇒ 8 * ( 9*t + 1 )
Here there are the two factors for the equation " 72 t+ 8 " that are <u>8 </u>and <u>9t+1.</u>
<u>Step 3 (optional) : </u>
Now check weather the factors are correct or not by multiplying factors with each other.
Multiplying ,
⇒ 8 * ( 9*t + 1 )
Gives -
⇒ 72 t+ 8
You must first attach the problems with your question.
Answer:
f(1) = 8
Step-by-step explanation:
Step 1: Define
f(x) = 7(x - 1) + 8
f(1) = x = 1
Step 2: Substitute and evaluate
f(1) = 7(1 - 1) + 8
f(1) = 7(0) + 8
f(1) = 8
ANSWER
EXPLANATION
The general term of the arithmetic sequence is
For the first term,we substitute
to get,
Similarly
The sum of the first n-terms is given by the formula,
where l is the last term.
In this case
We substitute these values to get,
We could have also used the formula,
The volume πr^2*height/3=1471
π*r^2=1471/9*3
π*r^2=490.33(I'm rounding all my numbers to the hundredths digit)
r^2=490.33/3.14(taking 3.14 for pi)=about 156.16
r= sqrt 156.16=about 12.5
Again this answer is not precise but I rounded everything to the hundredths digit because pi is never ending. I hope it helped!
