Answer: N(t) = (2^t)*1500

Step-by-step explanation:

Let's define the hour "zero" as the initial population.

So if N(t)  is the number of bacteria after t hours, then:

N(0) = 1500.

Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1

N(1) = 2*1500 = 3000

after two hours, at t = 2.

N(2) = 2*(2*1500) = (2^2)*1500

After three hours, at t = 3

N(3) = 2*(2^2)*1500 = (2^3)*1500

So we already can see the pattern, the number of bacteria after t hours will be:

N(t) = (2^t)*1500

Using translation concepts, it is found that the point (0, 0) on the graph of f(x) corresponds to point (4,-7) on g(x).

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

Considering the translations, the equivalent point is found as follows:

Hence the point (0, 0) on the graph of f(x) corresponds to point (4,-7) on g(x).

Step-by-step explanation:

Roselyn can drive a distance until she runs out of fuel for a time of 2.5 hours or until she spends all the fuel, whichever comes first.Roselyn can travel 120 km before running out

Distance travelled with 20 l of petrol in solution and final answer.

Roselyn's average speed is 60 kilometers per hour, and she needs to travel 150 kilometers to reach her family's place. Therefore, she will require a total of 150/60 = 2.5 hours to complete the journey.

The car's fuel efficiency is 6 kilometers per liter, meaning it consumes 1/6 liters of fuel per kilometer. To determine the total fuel required, we multiply the fuel consumption rate by the total distance: 150 * (1/6) = 25 liters of fuel.

Since the car's tank has 20 liters of fuel at the beginning of the drive, Roselyn will need an additional 25 - 20 = 5 liters of fuel to complete the journey.

As fuel costs 0.60 dollars per liter, Roselyn will need to spend a total of 5 * 0.60 = 3 dollars to purchase the necessary fuel.

Therefore, Roselyn can drive until she runs out of fuel for a time of 2.5 hours or until she spends all the fuel, whichever comes first.

1. Initial prediction for the data set with smaller Mean Absolute Deviation was Period A. Prediction was wrong.

2. The Mean Absolute Deviation for Period A is 1.8 and Period B, 1.1

This means that period B has a smaller Mean absolute deviation.

We start by finding the mean for each set;

Period A: Mean = (1×92 + 1×94 + 3×95 + 1×96 + 2×97 + 1×99 + 1×100)/10

= 960/10

= 96

Period B: Mean = (1×94 + 3×95 + 1×96 + 4×97 + 1×98)/10

= 961/10

= 96.1

Period A:

Mean Absolute Deviation = ((92-96) + (94-96) + 3(95-96) + (96-96) + 2(97-96) + (99-96) + (100-96))/10

Mean Absolute Deviation = (4 + 2 + 3 + 0 + 2 + 3 + 4)/10

Mean Absolute Deviation = 1.8

Period B:

Mean Absolute Deviation = ((94-96.1) + 3(95-96.1) + (96-96.1) + 4(97-96.1) + (98-96.1))/10

Mean Absolute Deviation = (2.1 + 3.3 + 0.1 + 3.6 + 1.9)/10

Mean Absolute Deviation = 1.1

Answer:

240 min

Step-by-step explanation:

if we convert it to minutes, one pool is drained in 360 min, while using another pump requires 720 min. the problem requires them working together, so we need to find the amount of pool drained in a unit pace, being one minute. using the first pump, in 1 minute 1/360 of the pool is drained, and 1/720 for the second pump. We can add them together, thus gaining 3/720 of the pool drained in 1 minute if they are applied together. then, you calculate 720/3 to find out how many minutes it takes for the whole pool to be drained, and you get 240

Step-by-step explanation:

rounding to the nearest ten, that is nearest to 1456 which would be 1460 (hope this helps! ) ♡

Answer:

1460

Step-by-step explanation:

Original number is 1 4 5 6

To round to the nearest ten, look at the digit in the 10's place and the digit immediately to the right of it

The digit in the tens place is 5

If the digit to the immediate right of this digit is 5 or greater, round the digit in the tens place up by one digit and set the immediate right digit to 0

So 5 rounds up to 6

The 6 to the immediate right(units place becomes 0)

1 4 5 6 rounded to nearest ten==> 1 4 6 0

The correct statement regarding the minimum value of the quadratic functions is given as follows:

D) The graphed function has a lower minimum value.

From the graph, the minimum value of the quadratic function is given as follows:

y = -8.

The algebraic function is defined as follows:

f(x) = 0.25x² - 2x.

Hence the coefficients are given as follows:

a = 0.25 and b = -2.

The x-coordinate of the vertex is given as follows:

x = -b/2a

x = 2/0.5

x = 4.

Then the y-coordinate of the vertex, representing the minimum value, is given as follows:

f(4) = 0.25(4)² - 2(4)

f(4) = -4 -> meaning that the graphed function has a lower minimum value.

The graph is given by the image presented at the end of the answer.

Answer: The answer will be 18

The number of years it will take the investment to amount to $6,000 is 8 years.

Simple interest is when the return on an investment grows at a linear rate. This means that the investment would grow at a constant value with the passage of time.

Time = Interest earned / (principal x interest rate)

Interest rate = value of the investment - amount deposited

$6,000 = $4,000 = $2,000

Time = $2,000 / ($4,000 x 0.0625)

Time = 8 years

Answer:

the restaurant will earn $406.25 in interest after 28 months.

Step-by-step explanation:

The first step is to calculate the annual interest rate. Since the account pays 3.5% simple interest on an annual basis, the annual interest rate is 0.035.

Next, we need to calculate the interest earned for 28 months. Since simple interest is being used, we can use the formula:

I = Prt

where I is the interest earned, P is the principal (the initial deposit), r is the annual interest rate, and t is the time in years.

Converting 28 months to years, we get:

t = 28/12 = 2.3333...

Rounding this to 2 decimal places, we get t ≈ 2.33 years.

Substituting the given values into the formula for simple interest, we get:

I = 50000.0352.33

Simplifying this expression, we get:

I ≈ $406.25

Therefore, the restaurant will earn $406.25 in interest after 28 months.

Answer:

To calculate the amount of interest the restaurant earned after 28 months, we need to use the formula I = Prt, where I is the interest, P is the principal amount (the amount initially deposited), r is the rate of interest (in decimal form), and t is the time period (in months).

Using this formula, we get: I = 5000*0.035*28 = 4200. Therefore, the restaurant will have earned $4200 in interest after 28 months.
