Answer:
Use properties:
cos(-θ) = cosθcos(θ + π) = - cosθsin²θ + cos²θ = 1Solution:
cosθ/(1 - sinθ) - (-cosθ)/(1 + sinθ) = cosθ([1/(a- sinθ) + 1/(1 + sinθ)] = cosθ[(1 + sinθ + 1 - sinθ)/(1 - sin²θ)] = cosθ(2/cos²θ) = 2/cosθProved

Critique Reasoning Jacob says that the surface
area of the cube is less than 1,000 cm2. Do you
agree with Jacob? Explain.
Answers
Answer: jacob is right
Step-by-step explanation:
each face in a cube is equal, and we know that there are six sides on a cube
this means that we need to find the surface area of one side and multiply it by six to see if jacob is correct
to find the area of one side you would do
a = Lw
a = 10 * 10
a = 100
so one face equals 100 cm^2 so 100 * 6 = 600
600 is less than 1000 so jacob is correct

Convert r = 8cos θ to rectangular form. A. x2 + y2 = 8y B. x2 + y2 = 64x C. x2 + y2 = 16x D. x2 + y2 = 8x
Answers
Given:
The given polar equation is:
[tex]r=8\cos\theta[/tex]
To find:
The rectangular form of the given polar equation.
Solution:
We know that,
[tex]r^2=x^2+y^2[/tex]
[tex]x=r\cos \theta[/tex]
We have,
[tex]r=8\cos\theta[/tex]
Multiply both sides by r.
[tex]r^2=8r\cos\theta[/tex]
[tex]x^2+y^2=8x[/tex]
Therefore, the correct option is D.

I need help to figure out the slope and y intercept of
3x + y = -2
Answers
Answer:
The slope is -3 and the y intercept is -2
Step-by-step explanation:
3x + y = -2
Solve for y
Subtract 3x from each side
3x-3x + y =-3x -2
y = -3x-2
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -3 and the y intercept is -2
Answer:
slope is up 3 over 1, and y int is y =3x + 2
Step-by-step explanation:
y = 3x + 2
