You randomly choose a letter from a hat with the letters a through j.
without replacing the first letter, you choose a second letter. find the
probability of the events.
1.choosing an h and then a d
2.choosing a consonant and then an e or an i
3.choosing a vowel and then an f
4.choosing a vowel and then a consonant

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.

this is a tricky question, lol,   but i think the answer is 100,000.

if your equation is in the form ax2 + bx + c, you can find the maximum by using the equation:

max = c - (b2 / 4a).

the first step is to determine whether your equation gives a maximum or minimum.

-x2 + 4x - 2.     thats an example hope it
