Answer: x=5

Step-by-step explanation:

lol ill do this one too :))

bc i answered the other one with a step by step explanation and this one is the same other than numbers ill just leave that out

slope = y2 - y1 / x2 - x1

-8 - 5 / 5 - 5

-13 / 0

nothing can be divided by zero, so the slope is undefined

this means that the line will be vertical and not have the usual y = mx+b form

it'll be x = a formula

so bc the x value in both points is 5, we know that x = 5 is the equation of the line :))

Find the sum of a finite geometric series. A ball is dropped from a height of 10 meters. Each time it bounces, it reaches 50 per

Sedaia [141]

Answer:

19.375 m.

Step-by-step explanation:

Before the first bounce it has travelled 10 meters.

Then after just hitting the ground the second time it has travelled 10 +1/2(10) = 15 m.

The common ratio is 0.5 and we want the sum of 5 terms

= a1 (1 - r^n) / (1 - r)

= 10 * (1 - 0.5^5) / (1 - 0.5)

= 19.375 m.

Sara is moving into a new apartment. The Resort complex charges a $600 security

vazorg [7]

Answer:

The rent is the same when 2 months have passed.

If she'd live in them for 6 months, I'd recommend the resort complex, since it'd be cheaper.

Step-by-step explanation:

Sara has two options, the resort complex and the uptown suites duplex, which can be represented by functions where "c" is the cost and "t" is the number of months Sara lives on each apartment.

The Resort complex:

$c_{resort}(t) = 600 + 950*t$

The Uptown Suites Duplex:

$c_{uptown}(t) = 300 + 1100*t$

To find the number of months she has to live in them in a way that they have the same cost, we need to find the value of t that makes both equations equal, this is done below:

$600 + 950*t = 300 + 1100*t\\1100t - 950t = 600 - 300\\150t = 300\\t = \frac{300}{150} = 2\\$

The rent is the same when 2 months have passed.

If she intends to live in them for 6 months, the cost of each are:

$c_{resort}(t) = 600 + 950*6 = 6300$

$c_{uptown}(t) = 300 + 1100*6 = 6900$

If she'd live in them for 6 months, I'd recommend the resort complex, since it'd be cheaper.
