A equals 3
Equation is g(x)=3f(x)
What i did is notice the y intercept is at 3 so I plugged in x=0 into the parent equation and got f(0)=1
So to get this equation to the y=3 intercept which is the g function, you have to multiply it by 3
Option C:
x = 90°
Solution:
Given equation:

<u>To find the degree:</u>

Subtract 1 + cos²x from both sides.

Using the trigonometric identity:




Let sin x = u

Factor the quadratic equation.

u + 2 = 0, u – 1 = 0
u = –2, u = 1
That is sin x = –2, sin x = 1
sin x can't be smaller than –1 for real solutions. So ignore sin x = –2.
sin x = 1
The value of sin is 1 for 90°.
x = 90°.
Option C is the correct answer.
Answer:
x = 
I'm not great at explaining answers like this. Please ask a teacher etc. for a better explanation!

Answer:
The y intercept is -2
Step-by-step explanation:
When looking for the y intercept you are looking for the point that is on the y axis and for this problem it is -2.
To find the perimeter you do length + width so you do 12.4 + 5.9 to get the perimeter.
