To grow 80000 bacteria, it will take 4.152 hours.

An exponential function is a Mathematical function in the form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

Given,

Initial number of bacteria = 4500

Number of bacteria get doubled each hour

Function for population growth of bacteria is given by

N = 4500(2ˣ)

x is time in hours

Future population is N = 80000

Then

80000 = 4500(2ˣ)

800 = 45 . 2ˣ

taking log on both sides

log 800 = log (45 . 2ˣ)

log(mn) = log m + log n and log mⁿ = nlogm

log800 = log45+ x log2

2.9030 = 1.653 + x . 0.3010

x = (2.9030 - 1.653)/0.3010

x = 4.152

Hence, it will take 4.152 hours to grow 80000 bacteria.

The question is incomplete:

The sum of the average amounts spent for veterinary expenses for​ dogs, cats, and birds in a recent year was ​$293 The average expenditure per dog exceeded the sum of the averages for cats and birds by ​$113. The amount spent per cat was 9 times the amount spent per bird. Find the average amount spent on each type of animal.

Answer:

The average amount spent in dogs is $203, in cats is $81 and in birds is $9.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y+z=293 (1)

x-y-z=113 (2)

y=9z (3)

You can replace (3) in (1) and (2):

x+9z+z=293

x+10z=293 (4)

x-9z-z=113

x-10z=113 (5)

Now, you have the following equations:

x+10z=293 (4)

x-10z=113 (5)

Then, you can isolate x in (4):

x=293-10z (6)

Next, you can replace (6) in (5):

293-10z-10z=113

293-20z=113

293-113=20z

180=20z

z=180/20

z=9

Now, you can replace the value of z in (6) to find x:

x=293-10z

x=293-10(9)

x=293-90

x=203

Finally, you can replace the value z in (3) to find y:

y=9*(9)

y=81

According to this, the answer is that the average amount spent in dogs is $203, in cats is $81 and in birds is $9.

Answer:

I seem to be late but I feel like the answer is X = 12.

Step-by-step explanation:

I will start out with my expression .

First step i take is adding 3 to both sides of the expression. \(\sqrt{x} +4 - 3+3 = 1 + 3\) . This leaves me with \(\sqrt{x}+4 = 4\).

My second step I will need to remove the check mark thingy away from the expression. In order for me to do that, I am going to have to square both sides of the expression giving me this!  \(\sqrt{x} +4^{2} = 4^{2} = x +4 = 16\) .

Now for my final step which will be to remove 4 from both sides of my expression. X + 4 – 4 =16 – 4 = x = 12.

Leaving me with my answer of X = 12

When we take a marble from the bag, the number of red marbles decreases by 1 and the total number of marbles decreases by 1 as well.

So after the first draw, the probability of getting a red marble on the second draw becomes 4/7 (since there are now 4 red marbles out of 7 total marbles).

To find the probability of getting 2 red marbles in a row, we multiply the individual probabilities of getting a red marble on each draw:

P(2 red marbles) = P(red marble on first draw) * P(red marble on second draw)

P(2 red marbles) = (5/8) * (4/7) = 20/56 = 5/14

So the probability of getting 2 red marbles in a row is 5/14.

When the cosine of an angle (0) is 3/5 and the angle lies in quadrant 4, the exact value of the sine of that angle is -4/5.

To find the exact value of sin(0), we can utilize the Pythagorean identity, which states that \(sin^2(x) + cos^2(x) = 1,\) where x is an angle in a right triangle. Since the terminal side of the angle (0) is in quadrant 4, we know that the cosine value will be positive, and the sine value will be negative.

Given that cos(0) = 3/5, we can determine the value of sin(0) using the Pythagorean identity as follows:

\(sin^2(0) + cos^2(0) = 1\\sin^2(0) + (3/5)^2 = 1\\sin^2(0) + 9/25 = 1\\sin^2(0) = 1 - 9/25\\sin^2(0) = 25/25 - 9/25\\sin^2(0) = 16/25\)

Taking the square root of both sides to find sin(0), we have:

sin(0) = ±√(16/25)

Since the terminal side of (0) is in quadrant 4, the y-coordinate, which represents sin(0), will be negative. Therefore, we can conclude:

sin(0) = -√(16/25)

Simplifying further, we get:

sin(0) = -4/5

Hence, the exact value of sin(0) when cos(0) = 3/5 and the terminal side of (0) is in quadrant 4 is -4/5.

A businessman has 7 suits

A businessman has 8 ties.

He is planning to take 4 suits and 3 ties with him on his next business trip.

We have to determining possibilities of selection he have.

Number of possible selections = \(^{7}C_{4}\times ^{8}C_{3}\)

Simplify

Number of possible selections = \(\frac{7!}{4!(7-4)!}\times\frac{8!}{3!(8-3)!}\)

Number of possible selections = \(\frac{7!}{4!3!}\times\frac{8!}{3!5!}\)

Number of possible selections = \(\frac{7\times6\times5\times4!}{4!\times3\times2\times1}\times\frac{8\times7\times6\times5!}{3\times2\times1\times5!}\)

Jorge will receive 9 hours in time off from work.

How many hours will Jorge get to take time off?

It is given that, Jorge has done overtime for 6 hours in this week. As per the Fair Labor Standards Act, for 6 hours of overtime work, he must be paid one and a half times the pay he gets per hour.

Instead of receiving an overtime pay for working 6 hours extra, Jorge decides to receive paid leaves from work, that is, he will get one and a half of the total hours for which he worked overtime.

As a result, the time off he receives from work = \(1\frac{1}{2} (6)\) hours

\(=\frac{3}{2}(6) = 9 hours\)

Thus, Jorge gets 9 hours in time off from work in return. The time that he earns for the overtime is equivalent to the pay he was supposed to receive for the overtime work.

Step-by-step explanation:

The given fractions have equal value, so Liam is correct.

Equivalent fractions are defined as fractions that have different numerators and denominators but the same value. For example, 2/4 and 3/6 are equivalent fractions because they are both equal to 1/2. A fraction is part of a whole. Equivalent fractions represent the same part of a whole.  

Liam is claiming that the fraction -(5/12) is equivalent to 5/-12.

Thus, we can say that:

The fraction  -(5/12) can be described as the opposite of a positive number divided by a positive number. A positive number divided by a positive number always results in a positive quotient and its' opposite is always negative.

The fraction 5/-12 can be described as a positive number divided by a negative number which always results in a negative quotient

The given statement  "If A = [a, b, c, d] and ab - cd cannot equal 0, then A is invertible." is true because An invertible matrix, also known as a non-singular matrix, is a square matrix that has an inverse. In this case, A is a 2x2 matrix with elements [a, b, c, d].

To determine if A is invertible, we need to check its determinant. The determinant of a 2x2 matrix A is computed as:
det(A) = ad - bc
In the given question, it is stated that ab - cd cannot equal 0, which means the determinant of A is not equal to zero. When the determinant of a matrix is not zero, the matrix is considered invertible or non-singular.

Therefore, given the condition provided, matrix A is invertible. The inverse of A can be found using the formula:
A⁻¹ = (1/det(A)) * [d, -b, -c, a]
Since det(A) ≠ 0, A⁻¹ exists, and A is invertible.

To test the significance of the relationship, a 5% level of significance was adopted.

1.The alternative hypothesis used to test the statistical significance of the relationship is: ne (not equal to).

2.To determine the critical value of the test statistic, we need to refer to the appropriate distribution table. The critical value depends on the significance level and the degrees of freedom. Since the degrees of freedom are not provided in the given information, we cannot calculate the critical value.

3.The test statistic can be calculated using the formula:

test statistic = (estimated coefficient - hypothesized value) / standard error of the coefficient. In this case, the estimated coefficient is -0.0059 and the hypothesized value is 0 (since we want to test if the coefficient is significantly different from zero). The standard error of the coefficient is 0.0029.

Test statistic = (-0.0059 - 0) / 0.0029 = -2.034 to two decimal places.

4.To determine whether the null hypothesis is rejected, we compare the test statistic with the critical value. Since we don't have the critical value, we cannot determine if the null hypothesis is rejected or not.

5.Since we cannot determine the rejection of the null hypothesis in part 4, we cannot conclude whether there is a linear relationship between resource abundance and economic growth based on this test alone.

The rejection or acceptance of the null hypothesis only provides information about the statistical significance of the relationship, but it does not determine the presence or absence of a linear relationship. Other factors and analyses should be considered to make a conclusion about the presence of a linear relationship.
