Answer: 32082.2

Step-by-step explanation:

Based on the given conditions, formulate:: 341300 * (2.3% + 4.4% + 2.7%)

Calculate the sum or difference: 341300 * 0.094

Calculate the product or quotient: 32082.2

Step-by-step explanation:

The time it takes for the wave to travel from point A to point B is 0.0086 seconds.

Assuming the question is referring to a sinusoidal wave with a frequency of 50 Hz, we can use the wave speed formula to calculate the time it takes for the wave to travel from point A to point B.

Wave speed (v) = frequency (f) x wavelength (λ)

Since the frequency is given as 50 Hz, we need to determine the wavelength to find the wave speed.

To calculate the wavelength, we can use the distance between two consecutive points on the wave that is in phase, such as points A and D or B and C. From the given information, we know that the distance between A and D or B and C is one wavelength. Therefore, we can calculate the wavelength as follows:

wavelength (λ) = distance between A and D or B and C = 10 m - 3 m = 7 m

Using the wave speed formula and the calculated wavelength, we can find the wave speed:

v = f x λ = 50 Hz x 7 m = 350 m/s

Now we can use the wave speed formula to find the time it takes for the wave to travel from point A to point B:

v = d / t

where d is the distance between A and B (which is 3 m) and t is the time it takes for the wave to travel that distance.

Rearranging the formula, we get:

t = d / v = 3 m / 350 m/s = 0.0086 s

Therefore, the time it takes for the wave to travel from point A to point B is 0.0086 seconds.

To find the amplitude of the wave, we would need additional information, as the amplitude is the maximum displacement of the wave from its equilibrium position.

As for whether points A and B are in phase, we need to compare the phase difference between the two points to the wave period. The period of a wave is the time it takes for one complete oscillation, and it is given by:

period (T) = 1 / frequency (f) = 1 / 50 Hz = 0.02 s

Answer:

In a rhombus, all sides are equal. Therefore, you can set WV (s+12) and UV (3s) equal to each other.

s+12 = 3s

Subtract s from both sides, so the variables are all on one side.

12 = 2s

Divide both sides by 2 to isolate the variable.

6 = s

UV = 3s

UV = 3(6)

UV = 18

To solve the triangle, or identify unknown portions in terms of known portions, we can apply the Pythagorean theorem and the properties of sines, cosines, and tangents.

She earned $12 at 4% interest rate. The solution has been obtained by using simple interest.

What is simple interest?

Simple interest is the cost of borrowing that is computed using the original principal amount alone and a constant interest rate.

We are given that Lauren deposited $300 to start her savings account and after one year, she had $312 in her account.

This means that the difference between both the amounts is the interest because it is mentioned that she did not deposit or withdraw any money that year.

So, the interest is $12.

The rate of interest is found using simple interest

⇒S = p*r*t

⇒12 = 300*r*1

⇒0.04 = r

This means that interest rate is 4%.

Step-by-step explanation:

If there is 200 feet of fencing available, the maximum possible area of the corral is 5000 Feet.

In the question, if there is 200 feet of fencing available, then we have to find the maximum possible area of the corral.

The formula of area of rectangle is:

A = L × B, where L is the length of the rectangle and B is the breadth of the rectangle.

The A = 200 feet and rectangular area is enclosed using the creek as one side and fencing for the other three sides, to create a corral.

So, L + 2B = 200

Subtract L on both side, we get

2B = 200 - L

Divide by 2 on both side, we get

B = 100 - L/2

A = f(L)

A = L·(100 - L/2)

A = 100L - [tex]L^2[/tex]/2

Now finding the derivative.

A' = [tex]\frac{df(L)}{dL}[/tex]

A' = -L + 100

Let A' = 0

-L + 100 = 0

Subtract 100 on both side, we get

-L = -100

L = 100 feet

Now putting the value of L in B = 100 - L/2.

B = 100 - 100/2

B = 100 - 50

B = 50 feet

The maximum possible area of the corral = 100 × 50

The maximum possible area of the corral = 5000 Feet

The initial battery charge was of:

19%.

The time it takes for the battery to be full is of:

32.4 minutes.

The linear function in slope-intercept format is given as follows:

y = mx + b

In which:

Each minute , the percentage of battery’s capacity that was charged increased by 2.5 percent, hence the slope m is given as follows:

m = 2.5.

Hence:

y = 2.5x + b.

After 17 minutes of charging the battery was 61.5 percent full, hence when x = 17, y = 61.5, and the intercept b is obtained as follows:

61.5 = 2.5(17) + b

b = 61.5 - 2.5 x 17

b = 19.

The battery is fully charged when y = 100, hence the time is obtained as follows:

2.5x + 19 = 100

2.5x = 81

x = 81/2.5

x = 32.4 minutes.

Answer: To find the time it takes for the toy boat to bob down from its peak to a height of -35 cm, we need to find the value of t when H(t) = -35.

So, we can substitute -35 for H(t) in the given equation:

5 cos (2π/3t) - 35.5 = -35

Now we can solve for t by isolating it on one side of the equation:

5 cos (2π/3t) = 0.5

cos (2π/3t) = 0.1

2π/3t = cos^-1(0.1)

3t = 2π * cos^-1(0.1)/π

t = 2 * cos^-1(0.1)

The time it takes for the toy boat to bob down from its peak to a height of -35 cm is approximately 2 * cos^-1(0.1) seconds.

The inequality that is modeled by the graph is 2x + 5y ≥ 14; x ≥ 0

This inequality corresponds to the solid line that passes through the ordered pairs (0,3) and (7,0). The line has a slope of -2/5, and it can be written in the form y = (-2/5)x + b, where b is the y-intercept, and it can be calculated as b = (5/2)x + 14. The shading is below the line and in the first and fourth quadrants, which corresponds to the inequality 2x + 5y ≥ 14; x ≥ 0.

The other inequalities provided in the options do not correspond to the graph:

   2x + 5y ≤ 14; x ≥ 0, the shading is above the line

   2x − 5y ≤ 14; x ≥ 0, the slope is positive and the shading is above the line

   −2x − 5y ≤ 14; x ≥ 0, the slope is positive and the shading is above the line

So, the inequality that is modeled by the graph is 2x + 5y ≥ 14; x ≥ 0

The number of algae after 7 days is approximately 70.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Given that,

Initial population of algae = 50

Percentage increase = 5%

To calculate the number of algae at any day, we need to find a formula.

Initial population = 50

After 1 day, population = 50 + (5% × 50) = 50 + (0.05 × 50) = 50 (1 + 0.05)

After 2 days, population = 50 (1 + 0.05)²

So, population after n days = 50 (1 + 0.05)ⁿ

Population of algae after 7 days = 50 (1 + 0.05)⁷

                                                      = 50 (1.05)⁷

                                                      = 70.355 ≈ 70

Hence there will be approximately 70 algae after 7 days.
