The equation that matches the number of bacteria in the population after 3 hours is y = 100(2)³.

What is an exponential function?

A mathematical function with the form f (x) = aˣ is an exponential function. "x" is a variable, while "a" is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.

Here, we have

Given: In a lab experiment, a population of 100 bacteria is able to double every hour.

We have to find the equation that matches the number of bacteria in the population after 3 years.

The equation for the number of bacteria after 2 hours is y = 100(2)³, where y is the number of bacteria and 300 is the initial number of bacteria.

This equation calculates the number of bacteria in the population after 2 hours by multiplying the initial number of bacteria by 2 raised to the power of the number of hours the bacteria has been doubling, or 2³ in this case.

Hence, The equation that matches the number of bacteria in the population after 3 hours is y = 100(2)³.

The result of (7 - 8i)(6 + 8i) is -22 + 8i, which is a simplified complex number.

A complex number is a number of the form a + bi, where a and b are real numbers and i is the imaginary unit (√(-1)). The real part of the complex number is a, and the imaginary part is bi. Complex numbers can be added, subtracted, multiplied, and divided, just like real numbers.

To perform the indicated operation (7 - 8i)(6 + 8i), we will use the FOIL method (First, Outer, Inner, Last). Let's multiply the real and imaginary parts separately and then combine them:

First: 7 * 6 = 42

Outer: 7 * 8i = 56i

Inner: -8i * 6 = -48i

Last: -8i * 8i = -64

Now, let's combine the results:

42 + 56i - 48i - 64

Simplifying further:

42 - 64 + 56i - 48i

Combining like terms:

-22 + 8i

Therefore, the result of (7 - 8i)(6 + 8i) is -22 + 8i, which is a simplified complex number.

Answer:

6.3 doesn't require scientific notation.  

Step-by-step explanation:

If one forced the scientific notation format, it would be:  6.3x10^0   10^0 = 1, so the result is 6.3.  No need to waste 10^x's when the number is already expressed as a single digit followed by a decimal point and additional digits.

It can be concluded that the cost to manufacture a pair of athletic shoes is $37.5 and the cost to manufacture a pair of casual shoes is $0. This indicates that there is a possibility  system of equations of an error in the information provided.

It is reasonable to assume that the cost to manufacture a pair of casual shoes is not $0.

Let x be the cost of manufacturing a pair of athletic shoes, and y be the cost of manufacturing a pair of casual shoes.

Therefore, The cost of manufacturing 20 pairs of athletic shoes is 20x The cost of manufacturing 10 pairs of casual shoes is 10y

The cost of manufacturing 25 pairs of athletic shoes is 25x The cost of manufacturing 20 pairs of casual shoes is 20y .

From the given information, the cost of manufacturing 20 pairs of athletic shoes and 10 pairs of casual shoes is $750.

Thus, the first equation is:20x + 10y = 750....(1)

The cost of manufacturing 25 pairs of athletic shoes and 20 pairs of casual shoes is $1200.Thus, the second equation is:

25x + 20y = 1200....(2)

To solve for x and y, multiply equation (1) by 2.40x + 20y = 1500....(3)Subtract equation (1) from equation (3) to eliminate y.20x

= 750x

= 750/20x

= 37.

Substitute the value of x into equation (1) and solve for y.20(37.5) + 10y

= 750750 + 10y = 750y = 0

Therefore, the cost to manufacture a pair of athletic shoes is $37.5 and the cost to manufacture a pair of casual shoes is $0.

It can be concluded that the cost to manufacture a pair of athletic shoes is $37.5 and the cost to manufacture a pair of casual shoes is $0.

This indicates that there is a possibility of an error in the information provided.

Step-by-step explanation:

Referring to Table 3.1, if the government imposes a price of $3, a shortage will result.

To determine the outcome when the government imposes a price of $3, we need to compare the quantity demanded and quantity supplied at this price level.
According to Table 3.1, at a price of $3, the quantity demanded is 30 units, while the quantity supplied is 40 units. The quantity demanded (30 units) is less than the quantity supplied (40 units), resulting in a situation known as a shortage.
A shortage occurs when the quantity demanded exceeds the quantity supplied at a given price. In this case, a shortage of 10 units occurs because consumers are willing to buy more than what producers are offering at the price of $3.
To summarize, if the government imposes a price of $3 based on Table 3.1, a shortage will result. This means that the quantity demanded exceeds the quantity supplied at the given price, indicating that consumers are unable to purchase all the units they desire.

The probability that Stella will score higher than 185 in her next bowling game is approximately 0.5 (or 50%) based on the normal distribution with a mean of 185 and a standard deviation of 14.

To calculate the probability that Stella's score will be higher than 185, we need to find the area under the normal distribution curve to the right of the mean.

First, we need to standardize the score using the z-score formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

In this case, x = 185, μ = 185, and σ = 14.

z = (185 - 185) / 14 = 0

Next, we need to find the probability associated with the z-score using a standard normal distribution table or a statistical calculator.

Since the z-score is 0, the probability of getting a score higher than 185 is equal to the probability of getting a score below 185, which is 0.5.

Therefore, the probability that Stella will score higher than 185 in her next game is approximately 0.5 (or 50%).
