Step-by-step explanation:

3cos2x +sinx=1

3(1-2sin²x)+sinx=1

3-6sin²x+sinx=1

sinx(-6sinx+1)=1

either

sinx=1

sinx=sin(90)

:.x=90

-6sinx+1=1

-6sinx=1-1

sinx=0/-6

sinx=sin0,sin180

:.x=0,180and90

<h3>The value of a is equal to 5.5</h3>

-22 = 11 - 6a

Add 6a to both sides.

6a - 22 = 11

Add 22 to both sides.

6a = 33

Divide both sides by 6.

a = 5.5

Question 19 What must be done to the graph of f(x) = |x| to obtain the graph of the function g(x) = 3/7 |x+4|-10?

Sergio [31]

Answer:

The graph of f is shifted left 4 units, vertically shrunk by a factor of $\frac{3}{7}$ and shifted down 10 units.

Step-by-step explanation:

The base graph is $f(x)=|x|$

The transformed graph is $g(x)=\frac{3}{7}|x+4|-10$

Let us rewrite $g(x)$ in terms of $f(x)$ to get:

$g(x)=\frac{3}{7}f(x+4)-10$

This means that $f(x)$ was vertically shrunk by a factor of $\frac{3}{7}$ and shifted 4 units to the left and 10 units down.
