Solve the equation for x.

1 answer:

6 0

You multiply 0.6 by 5x and 10 and you get 3x+6=-24. you then subtract 6 from both sides of the equation and you get 3x=-30. after that you divide both sides by 3 and you get x=-10. so the answer is B!

17. Identify the amplitude, period, and vertical shift for the

Stella [2.4K]

Answer:

$f(x)=2cos(x+\frac{\pi}{2})+3$

Step-by-step explanation:

Because the function is symmetric about the y-axis, using the cosine function is most appropriate.

Refer to the equation for a cosine function:

$f(x)=acos(bx+c)+d$

Amplitude: $|a|$

Period: $\frac{2\pi}{|b|}$

Phase shift: $-\frac{c}{b}$

Midline: $y=d$

The amplitude would be the average of the maximum and minimum y-values of the function, which would be $|a|=|\frac{5-1}{2}| =|\frac{4}{2}| =|2|=2$ .

The value of $b$ in $\frac{2\pi}{|b|}$ represents the length of the period, so since the length of the period is $2\pi$ , this means that $b=\frac{2\pi}{|2\pi|} =1$ .

The phase shift, $-\frac{c}{b}$ , describes the horizontal shift of a function. Because the phase shift is $-\frac{\pi}{2}$ , then we can set up the equation $-\frac{\pi}{2}=-\frac{c}{1}$ where we determine $c=\frac{\pi}{2}$ .

The midline (or vertical shift), $d$ , is the horizontal line that passes through between the maximum and minimum points, which the function oscillates. In this case, the midline would be located at the line $y=3$ , therefore, $d=3$ .
