"Have only 1 and itself as a factor" is definition of prime
so each factor must be prime
let ssay 2
2 is prime
2^4=16
a number is 16
Answer:
The new price of sneakers is the sum of the increase in the purchase price and the initial price. Hence, the new price is $138
The initial price of sneakers = $120
Percentage increase in price of sneakers = 15%
The new price of the sneakers can be calculated thus :
Initial price + price increase
Price increase = 15% × initial price
Price increase = 0.15 × $120 = $18
The new price of sneakers = $120 + $18 = $138
Therefore, the new price of sneakers is $138.
Answer:
f(-2) = 1
Step-by-step explanation:
The unknown terms are of even degree, so will have the same value for x=2 and x=-2. If we call those terms Q, then ...
... f(2) = Q +2 -1 = 5
... Q = 4
... f(-2) = Q -2 -1 = 4 -3
... f(-2) = 1
The first thing we are going to do for this case is to define the cosine and the tangent:
For the cosine we have:
Where,
C.A: adjacent leg
h: hypotenuse
On the other hand we have that the tangent is given by:
Where,
Where,
C.O: opposite leg
C.A: adjacent leg
We have then:
Part A
Simplifying:
Part B
