Can you check my question please? thanks for your help.
SVETLANKA909090 [29]

The correct option will be the last one: f(x)= 9sin(6 \pi x)+6

<em><u>Explanation</u></em>

The general equation for sinusoidal function is: f(x)= Asin(2\pi fx)+b, where A=Amplitude, f= frequency and b= y-intercept

Here the maximum value is 15 and the minimum value is -3. So, the distance between maximum and minimum values is 18. That means, the Amplitude, A= \frac{18}{2}=9

Frequency (f) is given as 3 and y-intercept(b) is 6

So, the required function will be:

f(x)= 9sin(2\pi*3x) +6\\ \\ f(x)= 9sin(6\pi x) +6

Select the fraction that is equivalent to 0.0368.
defon
Since the last number past the decimal is in the ten thousands place, the faction would then be 368/10,000 which can then be reduced to lowest terms to 23/625.

Determine the equation of the plane in the form
Bond [772]
A plane parallel to vectors <9, 6, 2> and <-8, -4, -5> is given by
\left|\begin{array}{ccc}x&y&z\\9&6&2\\-8&-4&-5\end{array}\right| =0\\ (-30 + 8)x - (-45 + 16)y + (-36 + 48)z = 0\\-22x+29y+12z=0

Since the plane passes through point (5, -5, 8), then
-22(5) + 29(-5) + 12(8) = -110 - 145 + 96 = -159

The required plane is -22x + 29y + 12z = -159
z = 11/6x - 29/12y - 53/4
