Which transformations are needed to change the parent sine function to

Mathematics

LenKa [72]3 years ago

Answer:

B

Step-by-step explanation:

The parent sine function is given by y=sin(x). For this function we have the following data

Period:2\pi

Phase Shift: 0 for Phase Shift is given by y=sen(x-k)=senx Then sin(x-0)=sinx

-k=0

When we transform this function, dilating it, we multiply the function by 1/4 or divide by 4, so we compress it. And Increase the phase shift by adding values to the x, like it was done in

y= 1/4 sin[4(x+pi/6)]

Period: \frac{\pi}{2}

Phase shift: - (\pi/6) For y=1/4 sin[4(x+pi/6)] as the sign of +\frac{\pi}{6} the phase shift is actually -\frac{\pi}{6} units, or \frac{\pi}{6} to the left.

What is the result when 3/8x + 2 1/5 is subtracted from 3 1/2x - 4 1/10?<br><br> Don’t put a link.
Umnica [9.8K]

Answer:

Option 3 3 1/8x - 6 3/10

Step-by-step explanation:

(3 1/2x - 4 1/10) - (3/8x + 2 1/5)

Divide it into parts:

(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)

3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x

-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10

So we get:

2 1/4x - 6 3/10

Answer:

21.6 or 22

Step-by-step explanation:

Triangles have same angles. This means that they are proportion.

50/27 = 40/x

when you cross multiply to solve x, 50x = 1080

so x = 21.6

If you have to nearest whole number, it will be 22
