Answer:
1st= 2 1/2
2nd= ???
3rd= 1/3
4th= 1/7
5th= 5/144
Step-by-step explanation:
We need to see the "given system".
<em>Greetings from Brasil...</em>
In a trigonometric function
F(X) = ±UD ± A.COS(Px + LR)
UD - move the graph to Up or Down (+ = up | - = down)
A - amplitude
P - period (period = 2π/P)
LR - move the graph to Left or Right (+ = left | - = right)
So:
A) F(X) = COS(X + 1)
standard cosine graph with 1 unit shift to the left
B) F(X) = COS(X) - 1 = -1 + COS(X)
standard cosine graph with 1 unit down
C) F(X) = COS(X - 1)
standard cosine graph with shift 1 unit to the right
D) F(X) = SEN(X - 1)
standard Sine graph with shift 1 unit to the right
Observing the graph we notice the sine function shifted 1 unit to the right, then
<h3>Option D</h3>
<em>(cosine star the curve in X and Y = zero. sine start the curve in Y = 1)</em>
The square of a prime number is not prime.
a) let x ∈ R, If x ∈ {prime numbers}, then
∉{prime numbers}
there says that if x is a real and x is in the set of the prime numbers, then the square of x isn't in the set of prime numbers.
b) Prove or disprove the statement.
ok, if x is a prime number, then x only can be divided by himself. Now is easy to see that
= x*x can be divided by himself and x, then x*x is not a prime number, because can be divided by another number different than himself

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set
. In other words, we define the y-intercept (let's call it
as:

Setting
in our function we have:

So <em>in this context the y-intercept is -16</em>
