(4) is the y-intercept in the equation, and is where you plot it on the y-axis. (-3) is your slope. If you were to graph it, here is the link to how it looks like.
The slope is 5/4.
5²+4²=41
√41=6.4
EF=6.4 units.
Answer:
Step-by-step explanation:
x = number of rows
780=x(x+4)


there are 26 rows and 30 students in each row 26*30=780
We know that DO and OX have equal side lengths. Since DX's length is 13, we divide 13 by 2 to get 6.5 as our answer for length OX. We also know that DO's length is also 6.5 because when we add 6.5 by 6.5, we get 13 as our total length of DX.
6.5 rounded to is 7.
So, length OX is 7 when rounded and that would be your answer.
Answer:
$1080
Step-by-step explanation:

convert % to decimal by multiplying 3.2%x100=0.032
then multiply by initial amount 3000x0.032
then multiply by 2 because it's compounding semiannual
then multiply by 3 because it's over a 3 yr period
do the same for the quarterly compound but multiply by 4 because it's quarterly

over a 3 yr period the quarterly compounded amount will earn:

$504 more than the account compounded semiannual
