r is worth - 0.542 mathematically if 1 2 r plus 6.5.
What is -2(-r -1) plus 1?
It is: 1+9+2 = 12
How do you simplify a plus ar?
( a + ar ) = a ( 1 + r )
What is the smallest possible value of 20P plus 10Q plus R when P and Q and R are different positive integers?
1
What is the formula for a geometric sequence?
a+a*r+a*r^2+...+a*r^n a = first number r = ratio n = "number of terms"-1
What is the r worth in f 1 2 r plus 6.5?
r is worth - 0.542 mathematically if 1 2 r plus 6.5.
Prove that nCr plus nCr minus 1 equals n plus 1Cr?
nCr + nCr-1 = n!/[r!(n-r)!] + n!/[(r-1)!(n-r+1)!] = n!/[(r-1)!(n-r)!]*{1/r + 1/n-r+1} = n!/[(r-1)!(n-r)!]*{[(n-r+1) + r]/[r*(n-r+1)]} = n!/[(r-1)!(n-r)!]*{(n+1)/r*(n-r+1)]} = (n+1)!/[r!(n+1-r)!] = n+1Cr
What is the answer to 1 over R plus 1 over T?
(r+t)/rt
What is the factor of m plus r-rm-1?
There is not the factor: there are two factors: (m - 1) and (1 - r)
Why 1 plus r in NPV calculation?
NPV=NFV/(1+r)^n The role of the "(1+r)^n" is to discount the future money to what it is worth in todays dollars. The 1 accounts to the sum itself and the plus r takes into account the interest rate.

Can rxr plus 7r plus 6 be factored?
I think so.r2 + 7r + 6 = [ (r+6) (r+1) ]
What is -2(-r -1) plus 1?
It is: 1+9+2 = 12

( a + ar ) = a ( 1 + r )
What does the 22nd row of Pascal triangle look like?
The terms in row 22 are 22Cr where r = 0, 1, 2, ..., 22. 22Cr = 22!/[r!*(22-r)!] where r! = r*(r-1)*...*3*2*1 and 0! = 1
What is the 29TH row of pascals triangle?
The terms in row 29 are: 29Cr = 29!/[r!*(29-r)!] for r = 0, 1, 2, ... 29 where r! denotes 1*2*3*...*r and 0! = 1
