Answer:
2258 cu. units
Step-by-step explanation:
you take 22/7 multiply by radius squared and multiply that by 5
If u and v are indeed vectors,
,
PEMDAS is important
Parentheses
Exponents
Multiplication
Division
Adding
Subtracting
There's no parentheses or exponents, so the first is multiplication. 9*3 is 27. Next is division, 6/2 is 3. Next is adding.
15+3+27=45
Answer:
2b. 3(2-x)
2c. add the 5x-10
5(x-2)
3.its suppose to be 12x+3=3(4x+1)
3(4x+1)=12x+3
Step-by-step explanation:
<u>Step-by-step explanation:</u>
We have , to simplify a complex expression . Basically a complex expression in the form a + ib , where i = 
and is called iota.
Expression:

We know that the mod or modulus of a complex number in the form of 
is represented by Z and Z = 
. Computing mod of 
as :
⇒
