A bacterial culture starts with 500 bacteria and doubles in size every half-hour.
tekilochka [14]

Answer:

a). 32000

b). T_{t}=500\times 4^{t}

c). 1259

Step-by-step explanation:

Growth of a bacteria is always exponential. Therefore, population of the bacteria is represented by the the geometric sequence.

Sum of the bacterial population after t hours will be represented by

T_{n}=ar^{n}

Where a = population at the start

r = ratio with the population is growing

n = time or duration of the growth in one hour

a). Population of 500 bacteria gets doubled after half an hour.

Or gets 4 times after an hour

This sequence will have a common ratio r = 4

and initial population a = 500

Therefore, population of the bacteria after 3 hours will be

T_{3}=500\times 4^{3}

T_{3}=32000  

b). After t hours number of bacteria will be represented by

T_{t}=500\times 4^{t}

c). We have to calculate the population after 40 minutes.

That means duration 't' = 40 minutes of \frac{2}{3} hours

By the formula,

T_{\frac{2}{3}}=500\times 4^{\frac{2}{3}}

T_{\frac{2}{3}}=1259.92 ≈ 1259

Therefore, number of bacteria after 40 minutes will be 1259.

I NEED HELP ON THIS CONSTRUCTED RESPONSE QUESTION! :(
zavuch27 [327]

Answer:


Step-by-step explanation:

She bought 18 ride tickets at $0.75 per ticket, so she spent 18 * $0.75 = $13.50 on rides. She spent a total of $33.50 for only admission and rides.

$33.50 - $13.50 = $20

Admission is $20.

(a) Let y represent total cost. Let x represent the number of ride tickets.

(b) y = 0.75x + 20

(c) The total cost is the cost of x ride tickets plus the admission.

x ride tickets cost 0.75x.

Admission is a fixed 20.

Adding the cost of ride tickets, 0.75x, to the admission cost, 20, gives you the total cost, y.
