ZanzabumX [31]3 years ago

Answer:

1. False 2. True

Step-by-step explanation:

For a geometric sequence,

\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}

1. The sequence is :

3, 13, 23, 33,...

\dfrac{13}{3}\ne \dfrac{23}{13}

It is not geometric. It is false

2. The sequence is :

5, -25, 125, -625

\dfrac{-25}{5}=\dfrac{125}{-25}\\\\-5=-5

So, the sequence is geometric as the common ratio is same. It is true.

VARVARA [1.3K]

Answer:

Again every triangle is 180° and so is every straight line, so 180-105 is 75° so 75°+85° is 160 and 180-160 is 20° so your missing angle is 20°

Answer:

I believe the correct answer would be A.) Profit.

Step-by-step explanation:

This is because <em>revenue</em> is the amount earned, which, in this case is $100,000. Loss is not a proper term. The proper term would be <em>expense. </em>This is the amount spent or lost. The correct answer would be <em>profit. </em>Profit just means the amount left after the expenses have been deducted from the revenue.

Hope this helps,

♥<em>A.W.E.</em><u><em>S.W.A.N.</em></u>♥

Determine the equation of the circle with radius 99 and center (-1,-8)(−1,−8).
kumpel [21]
<h2>Equations of Circles</h2>

Generally, you'd see the equation of a circle organized in the following format:

(x-h)^2+(y-k)^2=r^2

  • (h,k) is the center
  • r is the radius

To determine the equation given the center and the radius:

  1. Plug both pieces of information into the general equation
  2. Simplify

<h2>Solving the Question</h2>

We're given:

  • Radius: 99
  • Center: (-1,-8)

Plug the radius and center into the equation as r and (h,k):

(x-(-1))^2+(y-(-8))^2=99^2\\(x+1)^2+(y+8)^2=9801

<h2>Answer</h2>

(x+1)^2+(y+8)^2=9801
