The number of people playing a new phone app game triples every month. When the app first launched, 800 people started playing t

NeTakaya

Answer:

$a_t=ar^{t-1}$

t=6 months

Step-by-step explanation:

We are given that the number of people playing a new phone app game triples every month

When the app first launch , the number of people started playing the game right away=800

According to question

The number of peoples are currently playing the game=194,400

We solve by using the formula of geometric series because we get a geometric series pattern

The number of people playing the game when app game launch=800

The number of people playing game after one month=2400

800,2400,7200,........,194,400

$a_1=800,a_2=2400,a_3=7200,a_t=194,400$

We are finding common ratio

$\frac{a_2}{a_1}=\frac{2400}{800}=3$

$\frac{a_3}{a_2}=\frac{7200}{2400}=3$

Hence, the common ratio is 3 therefor nth term of G.P

$a_t=ar^{t-1}$

a=800,r=3, $a_t=194,400$

Substitute the values then we get

$194,400=800(3)^{t-1}$

$\frac[194400}{800}=(3)^{t-1}$

$243=3^{t-1}$

$3^5=3^{t-1}$

When base are same on both side then the power are equals

Therefore, t-1=5

t=5+1=6

Hence, when there are 194,400 people currently playing the game then

the number of months ,t=6 that have passed since the app launched.

Find the measure of z <br><br> 144<br> 120<br> 135<br> 108

SSSSS [86.1K]

The sum of interior angles in a regular octagon equals 1080 degrees.

So 1080 / 8 = 135

z = 135

Can you help me find the answer and explain it to me?

To find the area of a RIGHT ANGLE triangle, you do base x height then divide it by two.

(we divide by two because a parallelogram can be split into two triangles so we’re basically finding the area of that triangle twice to make an imaginary parallelogram then halving it to get the area of just the triangle).

because you didn’t attach a photo, im not entirely sure which length you gave is the height and base but because a rule for right angle triangles is that the longest length (called the hypotenuse) is always opposite the angle so we’re gonna assume that 32. 5cm is the hypotenuse for this triangle.

this means that 31.2cm and 9.1cm are our base and height length (interchangeable).

so we do
— 31.2 x 9.1 = 283.92
— 283.92 / 2 = 141.96cm squared (because it’s an area!)

hope this helped~ :)
