The equation in slope-intercept form for the line with slope (2)/(3) and y-intercept -6 is:

y = (2) / (3)x - 6.

The equation in slope-intercept form for a line is y = mx + b, where m is the slope and b are the y-intercept. Since the slope is (2)/(3) and the y-intercept is -6, we can substitute these values into the equation to get:

y = (2)/(3)x + (-6)

Simplifying this equation gives us:

y = (2)/(3)x - 6

Answer:

Let's call the first of the three consecutive integers "x".

According to the problem, the third integer (which is the one after the first two) is equal to twice the first increased by five. We can express this algebraically as:

third integer = 2x + 5

Since the three integers are consecutive, the second integer must be one more than the first, and the third must be one more than the second. So, the second integer can be expressed as:

second integer = x + 1

And the third integer is:

third integer = (x + 1) + 1 = x + 2

Now we can set these two expressions for the third integer equal to each other, since they both represent the same value:

2x + 5 = x + 2

Simplifying and solving for x, we get:

x = -3

So the first of the three consecutive integers is -3. The second is one more than the first, which is -3 + 1 = -2. And the third is one more than the second, which is -2 + 1 = -1. Therefore, the three consecutive integers are -3, -2, and -1.

Answer:

y = (-5/2)x - 3

Step-by-step explanation:

To find an equation of a line that is perpendicular to the given line and passes through the point (0, -3), we need to use the fact that perpendicular lines have opposite reciprocal slopes.

The given line has a slope of 2/5, so the slope of the line perpendicular to it is:

-1 / (2/5) = -5/2

This means that the equation of the perpendicular line has the form:

y = (-5/2)x + b

where b is the y-intercept we want to find.

Since the line passes through the point (0, -3), we can substitute these values into the equation and solve for b:

-3 = (-5/2)(0) + b

b = -3

Therefore, the equation of the line perpendicular to y = 2/5x + 4 with a y-intercept of -3 is:

y = (-5/2)x - 3

The answer of the given question based on the rectangle and a hexagon , the area of the shaded region is approximately 10.51 cm².

Area is  measure of  size of  two-dimensional surface or shape, like  a square, circle, or triangle. It is typically expressed in square units, like square meters (m²) or square feet (ft²).

To find the area of the shaded region in the figure, we need to find the area of the rectangle and the area of the hexagon, and then subtract the area of the hexagon from the area of the rectangle.

The rectangle has a length of 8 cm and a width of 2 cm, so its area is:

A(rectangle) = length x width = 8 cm x 2 cm = 16 cm²

The hexagon has a side length of 2 cm, so we can divide it into 6 equilateral triangles with side length 2 cm. Each of the  triangles has  area of an;

A(triangle) = (sqrt(3)/4) x side² = (sqrt(3)/4) x 2² = (2sqrt(3))/4 = sqrt(3)/2

The area of the hexagon is therefore:

A(hexagon) = 6 x A(triangle) = 6 x sqrt(3)/2 = 3sqrt(3)

A(shaded) = A(rectangle) - A(hexagon) = 16 cm² - 3sqrt(3) cm² ≈ 10.51 cm²

Therefore, the area of the shaded region is approximately 10.51 cm².

The rate at which the water level is rising when the water is 3m deep is 0.159 m/min.  The rate at which the tip of his shadow is moving when he is 40ft from the pole is 3ft/sec. The volume of a cone is given by V = 1/3πr^2h.

We are given that the base radius is 2m and the height is 4m. We are also given that the rate at which water is being pumped into the tank is 2 m^3/min. We need to find the rate at which the water level is rising when the water is 3m deep.

To find the rate at which the water level is rising, we need to take the derivative of the volume with respect to time. This gives us:

dV/dt = (1/3)π(2r)(dr/dt)(4) + (1/3)π(2^2)(dh/dt)

We know that dV/dt = 2 and r = 2, so we can plug these values into the equation and solve for dh/dt:

2 = (1/3)π(2)(2)(dr/dt)(4) + (1/3)π(2^2)(dh/dt)

Solving for dh/dt gives us:

dh/dt = (6 - 4π(dr/dt))/(4π)

We are given that the water level is 3m deep, so we can plug this value into the equation for the volume of a cone and solve for r:

V = (1/3)πr^2h

3 = (1/3)πr^2(3)

r = √(3/π)

We can now plug this value of r into the equation for dh/dt and solve for dr/dt:

dh/dt = (6 - 4π(√(3/π))(dr/dt))/(4π)

Solving for dr/dt gives us:

dr/dt = (6 - 4π(dh/dt))/(4π√(3/π))

We can now plug this value of dr/dt back into the equation for dh/dt and solve for dh/dt:

dh/dt = (6 - 4π((6 - 4π(dh/dt))/(4π√(3/π))))/(4π)

Solving for dh/dt gives us:

dh/dt = 0.159 m/min

The street light is mounted at the top of a 15ft tall pole and the man is 6ft tall. The man is walking away from the pole with a speed of 5ft/sec along a straight path. We need to find the rate at which the tip of his shadow is moving when he is 40ft from the pole.

We can use the properties of similar triangles to relate the height of the pole, the height of the man, the distance of the man from the pole, and the length of the shadow. Let x be the distance of the man from the pole and y be the length of the shadow. Then we have:

15/x = 6/(x + y)

Cross-multiplying gives us:

15(x + y) = 6x

Simplifying gives us:

9x = 15y

Taking the derivative of both sides with respect to time gives us:

9(dx/dt) = 15(dy/dt)

We are given that dx/dt = 5ft/sec, so we can plug this value into the equation and solve for dy/dt:

9(5) = 15(dy/dt)

The total distance traveled by the taxi driver is 7 1/2 miles.

To find out how many miles the taxi driver travels for the two stops, we need to add up the distance to the first stop and the distance to the second stop.

The distance to the first stop is 4 5/8 miles.

To find the distance to the second stop, we need to subtract 1 3/4 miles from the distance to the first stop:

4 5/8 miles - 1 3/4 miles = 2 7/8 miles

Now we can add the distance to the first stop and the distance to the second stop to find the total distance traveled:

4 5/8 miles + 2 7/8 miles

The monthly mortgage payment for a 30-year mortgage loan of $250,000 with an annual interest rate of 3% is about $1,054.63.

A monthly mortgage payment is the amount of money paid each month to repay a mortgage loan. The payment is typically made up of principal the amount borrowed and interest the cost of borrowing the money and may also include additional amounts for taxes and insurance.

We can use the formula for the monthly mortgage payment, which is:

M = P * r * (1 + r)^n / ((1 + r)^n - 1)

Where

First, we need to convert the annual interest rate to a monthly interest rate:

r = 3% / 12 = 0.0025

Next, we can plug in the values:

M = 250000 * 0.0025 * (1 + 0.0025)^360 / ((1 + 0.0025)^360 - 1)

We can simplify this expression and find that the monthly mortgage payment is approximately $1,054.63.

Therefore, the monthly mortgage payment for a 30-year mortgage loan of $250,000 with an annual interest rate of 3% is about $1,054.63.

The answer is no, these data do not indicate that the percentage of wheat crop lost to hail in that county is different (either way) from the national mean of 11%.

The sample mean is x = 12.1% and the population mean is μ = 11%. We want to test if there is a significant difference between the sample mean and the population mean. We can use a t-test to compare the means.

The null hypothesis is H0: μ = 11%, and the alternative hypothesis is Ha: μ ≠ 11%.

The t-statistic is calculated as:

t = (x - μ) / (σ / √n)

where x is the sample mean, μ is the population mean, σ is the standard deviation, and n is the sample size.

Plugging in the values, we get:

t = (12.1 - 11) / (5.0 / √16)
t = 1.1 / (5.0 / 4)
t = 0.88

Using a t-table with degrees of freedom (df) = 16 - 1 = 15 and α = 0.01, we find the critical value to be 2.947. Since the absolute value of the t-statistic (0.88) is less than the critical value (2.947), we fail to reject the null hypothesis. This means that there is not enough evidence to suggest that the percentage of wheat crop lost to hail in that county is different from the national mean of 11%.

Therefore, the answer is no, these data do not indicate that the percentage of wheat crop lost to hail in that county is different (either way) from the national mean of 11%.

Based on the probability distribution, the probability of a randomly selected account having 4 devices is 0.08. The probability of a randomly selected account having at least 3 devices is 0.44. The probability of a randomly selected account having 2 or 4 devices is 0.51. The mean number of devices per account is 2.39. The standard deviation of the distribution is 1.108. The probability that the number of devices in a randomly selected account lies within one standard deviation of the mean (inclusive) is 0.80.

For the given probability distribution, the probability of a randomly selected account having 4 devices is 0.08. This is because the total probability of all possible outcomes must equal 1. So, we can find the missing probability by subtracting the probabilities of the other outcomes from 1:

1 - 0.13 - 0.43 - 0.29 - 0.07 = 0.08

The probability of a randomly selected account having at least 3 devices is the sum of the probabilities of having 3, 4, or 5 devices:

0.29 + 0.08 + 0.07 = 0.44

The probability of a randomly selected account having 2 or 4 devices is the sum of the probabilities of having 2 and 4 devices:

0.43 + 0.08 = 0.51

The mean number of devices per account can be found by multiplying each possible outcome by its probability and summing the results:

(1)(0.13) + (2)(0.43) + (3)(0.29) + (4)(0.08) + (5)(0.07) = 2.39

The standard deviation of the distribution can be found by first calculating the variance and then taking the square root:

Variance = (1-2.39)^2(0.13) + (2-2.39)^2(0.43) + (3-2.39)^2(0.29) + (4-2.39)^2(0.08) + (5-2.39)^2(0.07) = 1.2279

Standard deviation = √1.2279 = 1.108

The probability that the number of devices in a randomly selected account lies within one standard deviation of the mean (inclusive) is the sum of the probabilities of the outcomes that fall within this range:

The correct answer is f^-1(x) = (8-√x)/2; f^-1 is a function.

To find the inverse of the function f(x) = (8-2x)^2, we need to switch the x and y variables and solve for y. This will give us f^-1(x).

So, we start with:

x = (8-2y)^2

Next, we take the square root of both sides:

√x = 8-2y

Then, we isolate the y variable:

2y = 8-√x

y = (8-√x)/2

So, the inverse of the function is:

f^-1(x) = (8-√x)/2

Now, we need to determine whether f^-1(x) is a function. To do this, we can use the horizontal line test. If a horizontal line intersects the graph of f^-1(x) at more than one point, then f^-1(x) is not a function.

In this case, a horizontal line will only intersect the graph of f^-1(x) at one point, so f^-1(x) is a function.

There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.

If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.

Given, Concrete tiles are made using buckets of cement, sand, and gravel mixed into the ratio of 1 : 4 : 6.

Now, 4×1 : 4×4 : 4×6, when it is 4 bucket of cement.

4 : 16 : 24.

Therefore, 24 buckets of gravel needed.

The exponential function showing the relationship between y and t is y = 16,000(0.78)^t

From the question, we have the following parameters that can be used in our computation:

Initial value, a = 16000

Rate = 22% decrement

The exponential function for the resale value y of the car, in dollars, after t years since the purchase can be expressed as:

y = a(1 - r)^t

Substitute the known values in the above equation, so, we have the following representation

y = $16,000 x (1 - 0.22)^t

Evaluate

y = 16,000(0.78)^t

Where 0.78 is the factor by which the resale value decreases each year, calculated as (100% - 22%) / 100% = 0.78.

Hence, the function is y = 16,000(0.78)^t
