Hello,
if f(x)=y=x+3
x=y+3==>y=x-3
f^(-1) (x)=x-3 is the inverse function of f(x).
So first you want to convert both to have the same denominator.
5 1/2 - 3 3/4
To:
5 2/4 - 3 3/4
Now, to make it easier for me, I would convert both to an improper fraction.
5 2/4 -> 22/4
3 3/4 -> 15/4
So now you can just do,
22/4 - 15/4,
which is just 7/4.
This in mixed number form is 1 3/4.
Answer:9.072×10³
Step-by-step explanation:
A number is said to be written in a scientific notation or standard form if it is expressed in the form a×10n where 1 is less than or equal to a and a is less than 10 and n is an integer
9072 is more than 10
So 9072÷10=907.2
Still 907.2 is more than 10
So 907.2÷10=90.72
Still 90.72 is more than 10
So 90.72÷10=9.072
9.072 is less than 10
We divided 9072 by 1000 and 1000 as a power of ten is 10³
So the answer is 9.072×10³
Vcylinder=hpir^2
VA=hpi6^2
VB=hpi(6/2)^2=hpi3^2
A times ?=B
?= a fraction
hpi6^2 times ?=hpi3^2
divide both sides by hpi
6^2 times ?=3^2
36 times ?=9
divide both sides by 36
?=9/36
?=1/4
1/4 of A is B
