Answer:
13x-4
Step-by-step explanation:
MO=7x-4
NO=6x
MO+NO=?
7x-4+6x=13x-4
Answer:
3.95 and -3.95
Step-by-step explanation:
To graph a circle you can use the formula or (x – h)^2 + (y – k)^2 = r^2. So substituting in the given, we get x^2+y^2=49/pi. The x intercept is when y=0. So x^2=49/pi and so
x = sqrt(49/pi) and rounding to the nearest tenth, we get 3.95 and -3.95 because it isn’t a principal square root.
3.4 inches per hour. because to solve ypu would dive 48 by 14 to get your answer.
20 because 19 16/33 is the exact answer. Since they ask about how much that can be rounded up to 20
You want to end up with 
. Expand this using the angle sum identity for sine:
We want this to line up with 
. Right away, we know 
.
We also need to have
Recall that 
for all 
; this means
Then
So we end up with
