Answer:
Step-by-step explanation:
sin2x = cosx + l
This can be written as:
2 sinxcosx = cosx + 1
One way would be to draw graphs of sin2x and cosx + 1 and see where they intersect.
Another way is to use y = tan(x/2), then sinx = 2y/(y^2+1) and cos x
= (-y^2 + 1) / (y^2 + 1) to substitute into the given equation and solve for y.
The algebra will be pretty challenging in this method.

Which point represents the ordered pair ( 1/4, -1/2)?
x = 0.25 , y= -0.5 , (x, y) represents the point (0.25,-0.5) in fourth quadrant of the cartesian plane as shown in the graph below attached.
What are cartesian coordinates in two dimensions ?
A Cartesian coordinate system in two dimensional is defined by x and y axes. Any point in the coordinate system is defined by a perpendicular distance from the x and y axes, (x, y). x and y axes intersect at the point where the value of x and y both is zero; this is called the origin (0,0)
Given ordered pair is ( 1/4, -1/2)
put (x,y) = ( 1/4, -1/2)
x= 1/4 =0.25 and y =(-1/2) = -0.5
This point lie in 4th quadrant
The point in the attached file represents the given point.

Given the definitions of f(x) and g(x) below, find the value of (fog)(-3).
f(x) = 3x² - 7x-3
g(x) = -4x - 10
The value of the composite function (f o g)(3) is 1603
How to evaluate the composite function?The functions are given as
f(x) = 3x² - 7x - 3
g(x) = -4x - 10
Next, calculate (f o g)(x) using
(f o g)(x) = f(g(x))
So, we have
(f o g)(x) = 3(-4x - 10)² - 7(-4x - 10) - 3
Substitute 3 for x.
So, we have
(f o g)(3) = 3(-4 x 3 - 10)² - 7(-4 x 3 - 10) - 3
Evaluate
(f o g)(3) = 1603
Hence, the value of the composite function (f o g)(3) is 1603

A circular arc has a measure of 2in and is intercepted by a central angle of 34. Find the radius of the circle
Answer:
68
Step-by-step explanation:
Answer:
For this particular problem (with units in mind), the formula for arc length is
Arc length
=
2
π
r
⋅
(
x
360
∘
)
,
Where
x
is the central angle measure and
r
is the radius of the circle.
You don't really have to work too hard to remember this formula. The arc length formula is easy to remember because it is just the circumference of the circle times the central angle over
360
∘
.
Anyway, let's continue with the problem. We are given that the central angle is
60
∘
, and that
r
, our radius, is
9
feet. So, let's plug that into our equation to find the arc length, in feet:
Arc length

Arc length
=

Now, you might be tempted to plug this in your calculator, but let's simplify it a little bit more.
