So for every hour bacteria grows 50. so what you need to do it multiply 50 by 19 then added it to 2400 because that's the amount it has currently.

Jeff invested $3000 in an account that earns 6.5% interest
goblinko [34]

Answer;

= $ 3623.85

Explanation;

To calculate compound interest we use the formula;

FV = OV( 1 + r/100)^n

FV=Future value which is what the value will be after the interest is calculated, this is what you are looking for.

OV=Original value, the amount of money you started with, in this case  

3000

r=interest rate, in this case its 6.5

n=years its being compounded annually, in this case 3

= 3000(1 + 6.5/100)^3

= 3623.848875

≈ 3623.85

How does the graph of the function g(x) = 5x + 1 differ from the graph of f(x) = 5*?
elena-14-01-66 [18.8K]

Answer:

C. It is translated up 1 unit.

Step-by-step explanation:

Translations of a function f(x)

To translate a function f(x) a units to the right, we have f(x-a)

To translate a function f(x) a units to the left, we have f(x+a)

To translate a function f(x) a units up, we have f(x) + a

To translate a function f(x) a units down, we have f(x) - a

In this question:

g(x) = 5x + 1

f(x) = 5x

This means that the function g(x) is 1 added to the function f(x), that is, it is translated up 1 units, and the correct answer is given by option c.
