The value of a collectible coin can be represented by the equation y = 2 x + 15, where x represents its age in years and y repre

Masteriza [31]

Answer:

53$

Step-by-step explanation:

They tell you the equation of how much the coin is worth after x amount of years

Step 1: Substitute x=19 into the equation y=2x+15

y = 2(19) + 15

Step 2: Solve for y

y = 2(19) + 15

y = 38 + 15

y = 53

Therefore the coin is worth 53 dollars after 19 years

Andre is working from home to a festival that is 1 5/8 km away. He takes a quick rest after walking 1/3 km what fraction of the

Anton [14]

Answer:

The fraction of trip completed by Andre is $\frac{31}{24}$ km

Step-by-step explanation:

Given as :

The Total distance between the home to a festival = 1 $\frac{5}{8}$ km

I.e The total distance between the home to a festival = $\frac{13}{8}$ km

The distance cover by Andre before taking rest = $\frac{1}{3}$ km

Let The fraction of trip completed by Andre = x km

So, <u>According to question</u>

The fraction of trip completed by Andre = The Total distance between the home to a festival - The distance cover by Andre before taking rest

or, x = $\frac{13}{8}$ km - $\frac{1}{3}$ km

or, x = $\frac{39 - 8}{24}$ km

∴ x = $\frac{31}{24}$ km

Or, The fraction of trip completed by Andre = x = $\frac{31}{24}$ km

Hence , The fraction of trip completed by Andre is $\frac{31}{24}$ km Answer

Find the sum of this infinite geometric series: 4 - 2.88 + 2.0736- 1.492992+...

kirza4 [7]

Let $r$ be the common ratio between terms. Then

$-2.88=4r\implies r=-0.72$

Now denote the $n$ th partial sum of the series by

$S_n=4-2.88+2.0736-1.492992+\cdots+4(-0.72)^{n-1}+4(-0.72)^n$

Multiply both sides by $-0.72$ , then subtract from the above to get

$S_n-(-0.72S_n)=4-4(-0.72)^{n+1}$
$1.72S_n=4(1-(-0.72)^{n+1})$
$S_n=2.32558(1-(-0.72)^{n+1})$

As $n\to\infty$ , you're left with

$S_\infty=2.32558$
