Answer:

This question is incomplete since you did not provide the options needed. Anyway, I will give you an explanation that will be useful for you to understand this.

Step-by-step explanation:

Understanding what a function is will allow you to have more clarity when solving the functions exercises and you will be prepared to understand more concepts that surround functions such as domain, image, relative extremes, their representation on the axes, etc.

A function is a relationship between two variables, one independent (x) and the other dependent (y) and for each value of x there corresponds ONE SINGLE VALUE OF <em>y</em>.

For example :

f(x) = 3x2 + 1

Calculate the circumference of the inscribed circle. [Use π = 3]

kiruha [24]

Answer:

To answer the question, we need a radius or diameter. For know, I hope this equation helps.

Step-by-step explanation:

C=2π<em>r</em>

Circumference = 2 (pi) radius

For your problem, it says to use 3 for pi.

C=2(3)<em>r</em>

*If you have the diameter, but not the radius, divide that number by 2. Your radius is half the diameter.

Find y. Please help!

Answer:

$y\approx 11.9$

Step-by-step explanation:

Here, we have the known angle sandwiched between two known sides.

So, we have SAS.

And we want to find the side opposite to the angle.

Therefore, we can use the Law of Cosines:

$c^2=a^2+b^2-2ab\cos(C)\\$

Again, it is important what we substitute.

a and b are the two side lengths. So, we will substitute 8 for a and 13 for b.

C is our angle. So, substitute 64 for C.

And c is what we’re trying to solve.

Therefore:

$c^2=(8)^2+(13)^2-2(8)(13)\cos(64)$

Simplify:

$c^2=64+169-208\cos(64)$

Add:

$c^2=233-208\cos(64)$

Take the square root of both sides:

$c=\sqrt{233-\cos(64})$

Use a calculator. So, c is approximately:

$c\approx11.9$

The c is our y. So, y is approximately 11.9 units.
