Answer:

<u>f(x) = 50 + 25(x - 1)</u>

Step-by-step explanation:

Let's write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:

Lifetime membership fee = $ 50

First video game is free

Then any video game purchased after = $ 25.

Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:

<u>f(x) = 50 + 25(x - 1)</u>

  • If x = 1, then f(1) = 50 + 0 = 50
  • If x = 2, then f(2) = 50 + 25 = 75
  • If x = 5, then f(5) = 50 + 100 = 150

Cloud [144]

Answer:

(A) The number of bacteria is originally 300 and increases by 30% every hour

Step-by-step explanation:

I am assuming the function should actually read:

N(t)=300\cdot 1.30^t

(i.e., there should be a "t" in the exponent. if this is not the case please disregard my answer).

According to the above exponential function, the initial amount 300 grows as (1+0.3)*300=300+0.3*300. In other words it increases by 30% every hour (t).

Your answer choice (A) is likely a candidate, except I am missing "every hour" at the end (again, am assuming this was omitted by mistake)

Alexxandr [17]

Answer:

$2,400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year,

then, solving our equation

I = 10000 × 0.06 × 4 = 2400

I = $ 2,400.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 6% per year

for 4 years is $ 2,400.00.
