To find the area of the coin/a circle we use this equation:
(a = area, r = radius, d = diameter)

a = r²

So we need to do for the radius.
r = d/2
r = 18/2
r = 9

Then solve
a = 9²
a = 81

The correct answer is 81.

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

Which pair of statements describes the end behavior of the graph of the function f(x) = x3 + 2x2 − 5x − 6?
notka56 [123]

A function assigns the values. The correct option is D.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.


The complete question is:

Which pair of statements describe the end behavior of the graph of the function f(x) = x³ + 2x² − 5x − 6?

A.) As x approaches negative infinity, f(x) approaches infinity. As x approaches infinity, f(x) approaches infinity.

B.) As x approaches negative infinity, f(x) approaches infinity. As x approaches infinity, f(x) approaches negative infinity.

C.) As x approaches negative infinity, f(x) approaches negative infinity. As x approaches infinity, f(x) approaches negative infinity.

D.) As x approaches negative infinity, f(x) approaches negative infinity. As x approaches infinity, f(x) approaches infinity.

If we draw the graph of the given function f(x) = x³ + 2x² − 5x − 6, then it can be observed that as x approaches -∞, f(x) approaches -∞. As x approaches ∞, f(x) approaches infinity.

Hence, the correct option is D.

Why is the graph wrong ​<br>and how would a fixed one look like
arlik [135]

Answer:

It's wrong because they are being paying $3 each day so it would be $3, $6, $9, $12, $15, $18 and so on. Not $5, $8, $11, and $14.

using the pythagorean theorem find the area of an equilateral triangle whose side measures 7 units find the area to the nearest
Molodets [167]
 <span>If you have an equilateral triangle, the median is also the altitude so - That means that if you draw altitude, it will bisect the base of the triangle and meet at two right angles. That gives you two of the measurements for the right triangle - the side (6) hypotenuse, and the base (3). You can then figure out the height using the Pythagorean as you have the a and the c for the theorem. Then you can use 1/2 base times height to find the area.
