Answer: 55 degrees

Step-by-step explanation:

this is a big one. so, first, we need to find the angle that we have enough information to solve, and that is angle 3. we can solve that because we know angle 4, and they are on the same line. a line is 180 degrees, so we just subtract angle 4 from 180. that way, we find angle 3. angle 3 ends up being 70. we also know that a triangle is 180 degrees total. so, we subtract 70 degrees from the inside, in order to find the other two angles. that leaves us with 110 degrees between the 2 other angles. and, since they are the same, we can just divide 110 by 2. that leaves us with each angle being 55 degrees.

Find vertex of: <br><br> y=(x-4)(x+8)

ki77a [65]

Answer:

(-2,-36)

Step-by-step explanation:

$y=(x-4)(x+8)$

<u>1) Find the zeros of the parabola</u>

The zero-product property states that any value, when multiplied by 0 will equal 0. Therefore, to make y=0, either (x-4)=0 OR (x+8)=0.

Therefore, x=4 and x=-8.

<u>2) Find the x-coordinate of the vertex</u>

To do this, we take the average of our zeros.

$\frac{4+(-8)}{2} \\=\frac{-4}{2} \\=-2$

Therefore, the x-coordinate of the vertex is -2.

<u>3) Find the y-coordinate of the vertex</u>

Plug the x-coordinate back into the original equation

$y=(-2-4)(-2+8)\\y=(-6)(6)\\y=-36$

Therefore, the y-coordinate of the vertex is -36.

Therefore, the vertex of the parabola is (-2,-36).

I hope this helps!

Which of the following functions represents an exponential decay with a 15% rate of change where A represents the initial value

melisa1 [442]

The function that represent this exponential decay is given as y = A(0.85)ˣ

<h3>What is an exponential function?</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

Given that A is the initial value, there is a decay of 15%, hence:

b = 100% - 15% = 0.85

The function that represent this exponential decay is given as y = A(0.85)ˣ
