Step-by-step explanation:

Answer:

0.0000045

\(10^5 = 10 * 10 * 10 * 10 * 10 = 100,000\\\\0.45 / 100,000 = 0.0000045\)

When it comes to tiny floating numbers, that means multiply a number by itself the number of times the floating exponent says to.

Answer:

\(0.0000045\)

Step-by-step explanation:

Rewrite it as a fraction:

\( \frac{0.45}{ {10}^{5} } \)

Calculate it:

\( \frac{0.45}{100000} \)

Rewrite the fraction:

\( \frac{45}{10000000} \)

Simply:

\( \frac{9}{2000000} \)

Turn it into a decimal:

\(0.0000045\)

Q = 180 ( 1.474) ^ t

This in in the form

y = a e ^ (kt)

180 is the initial value

a = 180

1.474 ^t = e^k ^ (t)

This means that e^k = 1.474

Taking the ln of each side

ln (e^k) = ln ( 1.474)

k = ln ( 1.474)

b = 1.474 which is the growth factor

b =1+r

1.474 = 1+r

r = .474

If they want r as a percent

r = 47.4 %

To sketch the frequency spectrum representing the modulated carrier psi(t) = (A + B * cos(ωt)) * cos(Nωt), we need to analyze the components and their corresponding frequencies in the equation.

The carrier signal psi(t) is given by the product of two cosine functions:

The first term (A + B * cos(ωt)) represents the envelope or amplitude modulation.

The second term cos(Nωt) represents the carrier frequency modulation.

To determine the frequency spectrum, we need to consider the frequencies involved in the modulation.

Carrier Frequency,

The carrier frequency is determined by the term cos(Nωt), where N is a large integer. The frequency of the carrier is Nω, which is a multiple of the angular frequency ω.

Sideband Frequencies,

The term A + B * cos(ωt) represents the envelope modulation. Since B * cos(ωt) is a cosine function with frequency ω, it creates two sidebands around the carrier frequency.

Lower Sideband, The lower sideband is located at a frequency ω - Nω.

Upper Sideband, The upper sideband is located at a frequency ω + Nω.

The sketch of the frequency spectrum will show the carrier frequency and the sidebands around it.

In the sketch, we have the carrier frequency fcarrier located at Nω, and the sidebands fsb located at Nω ± ω.

Please note that the amplitudes and specific values of A, B, ω, and N will determine the exact shape and positions of the frequency components in the spectrum. The sketch represents a general visualization of the frequency components based on the given equation.

The problem involves finding the rate at which the population of bacteria is growing after 1 hour and after 2 hours, given initial population of 1000 bacteria and growth equation p(t) = 1000(1 + 4t + 12t^2 + 50t^3).

We need to calculate the growth rate at these specific time intervals.To find the rate at which the population is growing after a certain time, we need to calculate the derivative of the growth equation with respect to time.

Taking the derivative of p(t) = 1000(1 + 4t + 12t^2 + 50t^3) with respect to t gives us the growth rate function:

p'(t) = 400 + 24t + 150t^2

To find the growth rate after 1 hour, we substitute t = 1 into the growth rate function:

p'(1) = 400 + 24(1) + 150(1)^2

p'(1) = 400 + 24 + 150

p'(1) = 574

Therefore, after 1 hour, the population is growing at a rate of 574 bacteria per hour.Similarly, to find the growth rate after 2 hours, we substitute t = 2 into the growth rate function:

p'(2) = 400 + 24(2) + 150(2)^2

p'(2) = 400 + 48 + 600

p'(2) = 1048

Therefore, after 2 hours, the population is growing at a rate of 1048 bacteria per hour.

The determinant of the matrix a with 8's on the diagonal, 1's above the diagonal, and 0's below the diagonal is det(a) = 8ⁿ, where n is the dimension of the matrix.

To find the determinant of the n×n matrix a with 8's on the diagonal, 1's above the diagonal, and 0's below the diagonal, we can use the property that the determinant of a triangular matrix is equal to the product of its diagonal elements.

Since the matrix a is an upper triangular matrix, its determinant is the product of its diagonal elements.

The diagonal elements of matrix a are all 8's. Therefore, the determinant of matrix a can be computed as follows:

det(a) = 8 * 8 * 8 * ... * 8 (n times)

      = 8ⁿ

Hence, the determinant of the matrix a is 8 raised to the power of n (det(a) = 8ⁿ).

This means that the determinant of matrix a is simply 8 raised to the power of the dimension of the matrix (n).

The specific values of the elements above and below the diagonal (1's and 0's, respectively) do not affect the determinant, as they do not contribute to the product when computing the determinant of an upper triangular matrix.

In summary, the determinant of matrix a is det(a) = 8ⁿ, where n represents the dimension of the matrix.

Answer:

The length of the shadow of a 6ft tall man at 5pm would be approximately 7.2ft.

Step-by-step explanation:

We can use the ratio of the heights to the lengths of the shadows to find the length of the shadow of a 6ft tall man. Here are the steps:

Write the ratio of the height to the length of Cindy's shadow:

5/6

Set up a proportion with the ratio of the height to the length of the shadow for the 6ft tall man:

5/6 = 6/x

Cross-multiply to solve for x:

5x = 36

Divide both sides by 5:

x = 7.2

and find that\[

\frac{4}{7}\cdot \frac{13}{13} = \frac{4\cdot 13}{91}=\frac{52}{91}, \text{and}

\]\[

\frac{8}{13}\cdot \frac{7}{7} = \frac{8\cdot 7}{91} = \frac{56}{91}.

\]Thus $\frac{8}{13}$ is larger than $\frac{4}{7}$, which tells us that $-\frac{8}{13}$ is smaller than $-\frac{4}{7}$. Thus, $x=-22$, $y=-\frac{8}{13}$, and\begin{align*}

\frac{x-y}{y}&=\frac{-22-\left(-\frac{8}{13}\right)}{-\frac{8}{13}}\\

&=\left(-22\cdot \frac{13}{13}+\left(\frac{8}{13}\right)\right)\cdot \left(-\frac{13}{8}\right)\\

&=\left(\frac{-286+8}{13}\right)\cdot \left(-\frac{13}{8}\right)\\

&=\left(-\frac{278}{13}\right)\cdot \left(-\frac{13}{8}\right)\\

&=\boxed{\frac{139}{4}}.

L * b = A

15 * b = 243.9

b = 243.9/ 15

b = 16.26 m

Now

Perimeter (p)

= 2 ( L + b)

= 2 ( 15 + 16.29)

= 62.58 m

Hope it will help

If area of a rectangle is 243.9 m2. If the length is 15 m, then  perimeter of the rectangle is 62.58 m.

The area of Rectangle is length times of width.

Given,

Area of rectangle (A) = 243.9 m²

Length (L) = 15 m

To find the  perimeter we need to know the breadth

Calculate the breadth (b)

Area=Length×Breatdth

243.9=15 × b

Divide both sides by 15

b = 243.9/ 15

b = 16.26 m

Perimeter= 2 ( Length + breadth)

= 2 ( 15 + 16.29)

= 62.58 m

Answer: 5

Step-by-step explanation:

If you received a gift of $10,000 3 years ago and you want to spend it in 3 years with interest rate is 4%, it will be worth $12,653.19. Option b is correct.

To calculate the future value of a present sum after a specified period, we can use the formula for compound interest:

Future Value = Present Value * (1 + Interest Rate)ᴺ

In this case, the present value is $10,000, the interest rate is 4% or 0.04, and the number of periods is 6 years because you received the gift 3 years ago and want to spend it in 3 years.

Using the formula:

Future Value = \(\$10,000 * (1 + 0.04)^6\)

Future Value = \(\$10,000 * (1.04)^6\)

Future Value = $10,000 * 1.1265319

Future Value ≈ $12,653.19

Therefore, the amount will be approximately $12,653.19. Option b is correct.

The probability that a mother is a carrier is approximately 0.018.

The Hardy-Weinberg equilibrium formula can be used to determine the frequency of alleles in a population, as well as to make predictions about the probability of certain traits occurring in the next generation. In this case, we are interested in determining the probability that a mother is a carrier of a particular disease, given that the frequency of the disease is 1/4300.

To use the Hardy-Weinberg formula, we need to know the frequency of both the dominant and recessive alleles in the population. Assuming that the disease allele is recessive (i.e., carriers are heterozygous), we can represent the frequency of the disease allele (q) as

\(q = \sqrt{(1/4300)} = 0.004644.\)

To determine the frequency of carriers (heterozygotes), we can use the formula p * q * 2,

where p represents the frequency of the dominant allele (which is equal to 1 - q in this case).

Therefore:

\(p = 1 - q \\ = 1 - 0.004644 = 0.995356\\q = \sqrt{(1/4300} = 0.004644\\p * q * 2 =0.018\)

Approximately 1.8% of the population will be carriers of the disease allele. This means that the probability that a mother is a carrier is approximately 0.018.
