Answer:

PY = 8

Step-by-step explanation:

Lets run down the other three to show why they're wrong

By P.T, that's wrong (PERPENDICULAR)

We can't prove that with the given

XY=42

Again, by P.T., this is false

BTW: You can prove PY=8 by proving XMP congruent to YMP by SAS

Well, you already have the decay model, so just plug that in

$\bf A=96e^{-0.000121\cdot 17000}\implies A=96e^{-2.057}$

The number of radians in a 540540540-degree angle can be written as a\piaπa, pi, where aaa is a constant, what is the value of a

Art [367]

Using proportions, it is found that the value of a is of 3.

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

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, a 180º angle has a measure of $\pi$ radians. What is the measure of a 540º angle? The <em>rule of three</em> is given by:

180º - $\pi$ rad.

540º - x $\pi$ rad.

Applying cross multiplication:

180x = 540.

x = 540/180 = 3.

The value of a is of 3.

What is the value of this expression when a = 3 and b = -2?

weqwewe [10]

The first step: Simplify the expression with:

$\dfrac{x^n}{x^m}=x^{n-m}\\\\(xy)^n=x^ny^n\\\\(x^n)^m=x^{nm}\\\\x^{-n}=\dfrac{1}{x^n}$

$\left(\dfrac{3a^{-2}b^6}{2a^{-1}b^5}\right)^2=\left(\dfrac{3}{2}a^{-2-(-1)}b^{6-5}\right)^2=\left(\dfrac{3}{2}a^{-1}b^1\right)^2\\\\=\left(\dfrac{3}{2}\right)^2(a^{-1})^2b^2=\dfrac{9}{4}a^{-2}b^2=\dfrac{9b^2}{4a^2}$

The second step: Put the values of a = 3 and b = -2 to the expression:

$\dfrac{9(-2)^2}{4(3)^2}=\dfrac{(9)(4)}{(4)(9)}=1$
