Answer:
and
Step-by-step explanation:
We are given that sin x+cos x=cos 2x
We have to solve the given equation for
Because
Tan x is positive in I and III quadrant
In III quadrant angle replace by
Therefore,
Answer:
y= 5x+20
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
The slope is 5 and a point on the line is (-4,0)
Substituting this information into the equation, we can solve for b
0 = 5(-4) +b
0 = -20+b
Add 20 to each side
0+20 = -20+20+b
20 = b
y = 5x+20
F(x)=x^2+1
f(10)=(10)^2+1=100+1=101
