solution for #18 is C and for #19 is D
Answer:
log base 10 of 40/9, log(40/9), or 0.6478
Step-by-step explanation:
Easiest and fastest way to do this is to plug it into the calc because the log base 10 of those numbers given will be nasty decimals.
(-2,-3) would make these two triangles congruent.
If you look at the slope of line DE, you see it has a -1 slope.
Line BA also has a -1 slope.
So line AC = line FE and line BC = line FD
The slope of AC is 3
The slope of BC is 1/3
Two possible points for F are (2,1) and (-2,-3)
Since (2,1) is not an option, C. (-2,-3) is your answer.
Eduardo is thinking of the number ' 16 '.
The factors of 16 are 1, 2, 4, 8, and 16.
Here's a cool little factoid:
Almost every number has an even number of factors. The
only ones that have an odd number are perfect squares.
(They still have an even number of factors, but two of the factors
are the same number, so the list looks like an odd number long.)
Hi hope I can help, so first you do 45÷3 which = 15 so 15 is your answer
