Answer:

See below...

Step-by-step explanation:

For a function whose formula is in this pattern:

$y=A\sin\left(B(x-C)\right)$

Amplitude: $|A|$

Period: $\frac{2\pi}{B}$

Phase Shift: C

In this question, $A=4,\,B=2,\,C=\frac{3\pi}{4}$

Amplitude: 4

Period: $\frac{2\pi}{2}=\pi$

Phase Shift: $\frac{3\pi}{4}$

There is no vertical shift, so the midline is the x-axis whose equation is y = 0.

Also, because there is no vertical shift, the maximum is 4 and the minimum is -4.

The graph is attached.

What is the length of side AC of the triangle?<br><br> Enter your answers in the boxes.

inessss [21]

Answer:

$AC=25$

Step-by-step explanation:

From the given figure, it can be seen that ${\angle}A={\angle}C$ , thus ΔABC is an isosceles triangle.

Therefore, $AB=BC$

⇒ $5x+5=7x-1$

Solving the above equation, we get

⇒ $5x-7x=-1-5$

⇒ $-2x=-6$

⇒ $x=3$

Now, substituting the value of x in AC, we have

⇒ $AC=6x+7$

⇒ $AC=6(3)+7$

⇒ $AC=18+7$

⇒ $AC=25$

Thus, the length of the side AC of the given triangle is 25 units.

Genrish500 [490]

N, N+2, and N + 4 are the ages

(N + 4) - (2N) = (N + 2) -24

4 - N = N - 22

2N = 26

N = 13

The brothers are 13, 15, and 17 years old.
