Answer:

$f(x)=2e^{-kx}$

in a graph the x value at the y intercept is 0

$f(x)=Ae^{-kx}$ is a typical decay function

if x = 0 thus $e^{-kx}$ = 1

so at 0 the function value would be A

$f(x)=2e^{-kx}$

There is a bag filled with 5 blue, 6 red and 2 green marbles.

vodka [1.7K]

The probability of getting exactly 1 green will be 1/13.

<h3>What is probability?</h3>

The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,

Given data;

No of blue marbles= 5,

No of red marbles=6

No of green marbles=2

Total no of ball = 5+6+2

Total no of ball = 13

The probability of getting one green marble is;

P(G)=1/13

Hence, the probability of getting exactly 1 green will be 1/13.

C. Assume someone has an average balance account with a bank that costs $35 a month but earns

Elodia [21]

Answer:

The total interest earned after subtracting the monthly $35

service fee = $975 - $35 = $940

Step-by-step explanation:

Bank fee cost per month = $35

Interest rate per month = 1%

The total amount in the account until the 15th = $100,000

The total amount in the account from the 15th to the 30th = $95,000

Interest Earned?

Interest earned for first 15 days:

= $100,000 times 1%/2

= $100,000 times 0.001/2

= $500

Interest earned from 15th to the 30th:

= $95,000 times 1%/2

= $95,000 times 0.001/2

= $475

Interest earned for first 15 days + Interest earned from 15th

to the 30th = $500 + $475 = $975

So, the total interest earned after subtracting the monthly $35

service fee = $975 - $35 = $940

I don’t get how you do this please help

vladimir2022 [97]

This is just a reflection. Not sure what your question is so I’ll just explain reflections. Reflections are flipping a shape across that certain line. Here, it is the X axis. What I usually do is see how far away each point is away from the (line of reflection) x axis. For example, G is 5 points away from the x axis, so the reflection of G is also 5 points away from the x axis. This works with any point of the shape. Hope this helped!
