Solve x2 − 3x = −8.

1 answer:

8 0

Do you mean x^2. If so we make the equation equal to zero. x^2-3x+8=0. Now solve using the quadratic formula to get (3 ±i√23)/2

Find the probability of drawing an 8 and then a queen (with replacement) from a standard deck of cards

murzikaleks [220]

Prob (8) = 4/52 = 1/13

Prob(Queen) = 4/52 = 1/13

Prob ( 8 then a queen) = 1/13 * 1/13 = 1/169 answer

The probabilities are multiplied beause the 2 events are independent

In properties of logarithms, what is log2 25?

spayn [35]

$log_a(b)=c$ $log_a(b)=c$ translates to

$a^c=b$ $a^c=b$
let's say it equals y

$log_2(25)=y$ $log_2(25)=y$
trsnaltes to
$2^y=25$ $2^y=25$
doesn't help us
we can also translate it to
$log_2(5^2)$ $log_2(5^2)$ or $2log_2(5)$ $log_2(5^2)$
