Answer:
? = 32.20422
Step-by-step explanation:
We know the adjacent side and the hypotenuse
cos ? = adj / hyp
cos ? = 33/39
cos ? = 11/13
Taking the inverse cos of each side
cos ^ -1( cos ?) = cos^-1(11/13)
? = 32.20422
Answer:

Step-by-step explanation:
To find which one is prime, let's try to factor them all. We can use the factoring by grouping method.

and
and
So this one is not prime, since you can still factor it.

and
and
So this one is not prime, since you can still factor it.

and
and
So this one is not prime, since you can still factor it.

and
and -x+2 cannot be further factored.
Therefore,
is a prime.
Answer:
y= 5 + 0.9x
Step-by-step explanation:
Giving the following information:
NYCab company charges an initial rate of $5.00 for a ride, plus $0.90 for each mile driven.
<u>We need to structure the total cost formula:</u>
y= total cost
x= miles driven
fixed cost= $5
Unitary variable cost= $0.9
y= 5 + 0.9x
6a+15+5a-10
11a+5 this is the answer
Answer:
40%
Step-by-step explanation:
