6. Classify the following functions as exponential growth or decay. (4 pts)

1 answer:

6 0

A) growth; B) decay; C) growth; D) decay

A is growth because the value of b raised to the exponent is larger than 1.
B is decay because the value of b raised to the exponent is smaller than 1.
C is growth because the value of b raised to the exponent is larger than 1.
D is decay because the value of b raised to the exponent is smaller than 1.

YA is the angle bisector of ZXYZ. If mZXYZ = 52°, what is mZZYA?

antoniya [11.8K]

Given:

$YA$ is the angle bisector of $\angle XYZ$ .

$m\angle XYZ=52^\circ$

To find:

The measure of $m\angle ZYA$ .

Solution:

It is given that $YA$ is the angle bisector of $\angle XYZ$ . It means

$m\angle XYA=m\angle ZYA$ ...(i)

Now,

$m\angle XYA+m\angle ZYA=m\angle XYZ$

$m\angle ZYA+m\angle ZYA=52^\circ$ [Using (i)]

$2m\angle ZYA=52^\circ$

Divide both sides by 2.

$m\angle ZYA=\dfrac{52^\circ}{2}$

$m\angle ZYA=26^\circ$

Therefore, the required value is $m\angle ZYA=26^\circ$ .

What is 15% of $32.50 and please explain how you got your answer please

Ann [662]

You can say : 15% ⇒ ? if 100% ⇒ 32.50 $
so next you can say : 15/100 = ?/32.50 ⇒ ? = (15/100) × 32.50 = 15 × 32.50 ÷ 100 = 4.875 ⇒ so the answer is 4.785 $ ;D i hope this will be helpful :))
