Write the expression as the sine, cosine, or tangent of an angle.

Find the general solution for cos x = 0, where n is an integer.

First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2

Now, this is the answer for angles between 0 and 2pi

but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:

x = pi/2 + n*pi

here n is any integer.

Work out the circumference of the circle when the radius is 6mm and give the answer in terms of pie.

s344n2d4d5 [400]

_______________________________

Hey!!

Solution,

Radius(r)= 6 mm

Circumference of circle=?

Now,

Circumference of circle=2 pie r

 =2*pi*6

 =12 pie

So the answer is 12 pie.

Hope it helps...

Good luck on your assignment

Which graph shows the same end behavior as the graph of f(x) = 2x6 - 2x2 - 5?

aleksandrvk [35]

Step-by-step explanation:

End behavior of a polynomial function is the behavior of the graph of f(x) as x tends towards infinity in the positive or negative sense.

Given function:

f(x) = 2x⁶ - 2x² - 5

To find the end behavior of a function:

Find the degree of the function. it is the highest power of the variable.

Here the highest power is 6

Find the value of the leading coefficient. It is the number before the variable with the highest power.

Here it is +2

We observe that the degree of the function is even

Also the leading coefficient is positive.

For even degree and positive leading coefficient, the end behavior of a graph is:

x → ∞ , f(x) = +∞

x → -∞ , f(x) = +∞

The graph is similar to the attached image
