Answer:

About $1,178,974

Step-by-step explanation:

Alright, the sequence we have right now is:

500,000       550,000      605,000

We want to find the common ratio, so let's divide 550,000 by 500,000 and see if we get the same value as 605,000 divided by 550,000:

550,000/500,000 = 1.1

605,000/550,000 = 1.1

Now, we know that r = 1.1. We also know the first term is: a_1 = 500,000.

We use the explicit rule of a geometric sequence:

a_n=a_1*r^{n-1}

Here, we want to find a_{10} , which means that n = 10. We know r and a_1, so we just plug in these values:

a_{10}=500,000*(1.1)^{10-1}=500,000*(1.1)^{9} ≈ 1,178,973.85 ≈ 1,178,974

Thus, the answer is about $1,178,974.

Hope this helps!

!!!The volume of the given figure is______!!!!
choli [55]

Answer:

284.837734 ft^3 rounded up to 284.84 ft^3

Step-by-step explanation:

Cylinder Volume: pi*r^2h

pi*4^2*4=201.06193

Cone Volume: pi*r^2*(h/3)

pi*4^2*(5/3)=83.7758041

201.06193+83.7758041=284.837734

284.837734 ft^3

What is the midpoint of the line segment -1, 2 and 9, 5
Effectus [21]

Answer:

So if I did my math right it should be (4,3.5)

Step-by-step explanation:

The formula for finding a midpoint of a segment is (x1+x2/2 , y1+y2/2)

So first you grab both x's out of (-1,2) and (9,5).

So -1 and 9.

Then you add them and divide them by 2 to get 4

Then you grab the y's out of (-1,2) and (9,5)

So 2 and 5.

Add 2 and 5 together and divide them by 2.

That's when you should get 3.5

So the midpoint should be (4,3.5)
