how do you solve these problems?? (i already know the answers, i just dont understand how to solve it)
The function f is given by f(x)= x^2 - 6x + 13, for x is greater than and equal to 3.
1. write f
Adding in some number might help. Use 600 for example. Martha can rake 600 leaves in 4 hrs while her brother rakes 600/6 hrs. So martha is 150 leaves/hr while brother is 100leaves/hr. Together, they a
Please explain/show how to approach this problem!
Thanks!-Assuming addition as the operation, we want to find all elements b in Z_15 where
5b = 0 (mod 15).
[Since 5 is prime, no smaller positive in
1. 1/2 + 1/5 + 1/10 + 1/17 + 1/26
Are you supposed to find a formula and then integrate that?-Im assuming that goes on forever, rather than just stopping at 1/26.
Probably...its 1/(n^2 + 1). That in
Pls, I really need help on this:
1. If and H and K are subgroups of G, show that if G is finite, then [G:H] = [K:H] [G:K].

Without a calculator-since 2 feet= 24 inches,
so 23=24+3=27 inches,
and yard =36 inches,
so 27/36 yard=

divide total by inches in a yard
convert answer to percent of

1. If (1-2k)x^2 + 8kx - (2+8k) = 0 has equal roots, find the value of k.
2. If x^2 + kx + 2x + 2k = 0has real and equal roots, find the value of k.
