Answer:

h(5) = 20

Step-by-step explanation:

Assume that '2' is an exponent.

So the question for you should be:-

\( \displaystyle \large{h(x) = {x}^{2} - x}\)

We want to find h(5); we substitute x = 5 in.

\( \displaystyle \large{h(x) = {5}^{2} - 5}\)

5^2 is 5•5 = 25.

\( \displaystyle \large{h(x) = 25 - 5} \\ \displaystyle \large{h(x) = 20}\)

Therefore, h(5) is 20.

As the question suggests, we need to use Pythagorean Theorem!

\(a^{2}\ +\ b^{2}\ = c^{2}\)

You are given the hypotenuse and one of the sides therefore you need to rearrange your formula like so:

\(a^{2}=c^{2}-b^{2}\)

Substitute your values and solve.

\(a^{2}=17^{2}-15^{2}\\a^{2}=289-225 \\a^{2}=64\\\sqrt{a^{2}} =\sqrt{64} \\\)

a = 8 meters

Step-by-step explanation:

From the graph, we have the amount of water (in liters) on the y-axis and the time (in minutes) on the x-axis

a)

To obtain the amount of water at zero minutes, we will trace the y-value that corresponds with the value of zero on the x-axis: we will see this to be 270 liters

Therefore, at time zero minutes, the amount of water is 270 liters

b)

We will answer this by picking two points that lie along the straight line and calculate the slope. We pick the points:

We will proceed to calculate the slope as shown below:

The slope is -90 liters per minute.

The negative sign (-) means that as time increases, the amount of water in the aquarium decreases

The water decreases at a rate of 90 liters per minute

Rate of change of the function, dC/dW = 3

Let the cost be represented as C

Let the wight be represented as W

The rate of change of the function can be calculated using the formula:

The measures of angles 4 and 5 are:

∠5 = 104°

∠4 =76°

On the image we can see that angles 1 and 2 are next to eachother, that means that the sum of their measures must be a plane angle, that is an angle of 180°.

Then we can write the sum:

∠1 + ∠2 = 180°

(3x + 5) + (2x + 10) = 180

5x + 15 = 180

5x = 180 - 15

x = 165/5 = 33

the measure of angle 5 is the same one of angle 1 then:

∠5 = (3*33 + 5)° = 104°

And angle 4 is supplementary of angle 1, then:

∠4 + 104° = 180°

∠4 = 180 - 104= 76°

These are the measures

The estimated median price of a single-family home in Charleston/No. Charleston in the 1st Quarter of 2008 is $201,048. If the median price continues to decrease at the same rate for the next two years, the estimated median price of a single-family home in the 1st Quarter of 2011 would be $144,458.

(a) To estimate the median price of a single-family home in the 1st Quarter of 2008, we need to calculate the original price before the 8.15% decrease. Let's assume the original price was P. The price after the decrease can be calculated as P - 8.15% of P, which translates to P - (0.0815 * P) = P(1 - 0.0815). Given that the end of 1st Quarter of 2009 median price was $184,990, we can set up the equation as $184,990 = P(1 - 0.0815) and solve for P. This gives us P ≈ $201,048 as the estimated median price of a single-family home in the 1st Quarter of 2008.

(b) If the median price of a single-family home falls at the same rate for the next two years, we can calculate the price for the 1st Quarter of 2011 using the estimated median price from the 1st Quarter of 2009. Starting with the median price of $184,990, we need to apply an 8.15% decrease for two consecutive years. After the first year, the price would be $184,990 - (0.0815 * $184,990) = $169,805.95. Applying the same percentage decrease for the second year, the price would be $169,805.95 - (0.0815 * $169,805.95) = $156,012.32. Therefore, the estimated median price of a single-family home in the 1st Quarter of 2011 would be approximately $144,458.

1.1 cm is the 1/360th of the circumference. The circle's circumference is 69.72% of the arc that the angle's rays subtend.

We must comprehend and use the relationships between arc length and circumference in this question. By using geometry, we can determine that a circle's central angle is 360 degrees, and that the circle arc is directly proportional to the central angle.

The angle's rays' subtend an arc that is 69.72% the diameter of the circle.

The circumference's length is multiplied by 1/360 to get the 1/360th of the circumference, and the resulting measurement is

s= 1/360 x 396

= 1.1

the circumference is 1.1 cm.

By dividing the subtended arc by the arc length, one may determine the arc that the angle's subtend rays :

Betrys needs another 400 grams of diced potatoes to make her vegetable stew for 8 people.

We know that Betrys is cooking for 8 people, and we know that a recipe for 2 people needs 10 ounces.

8 people is 4 times 2 people, then for 8 people you need 4 times 10 ounces, this is 4*10 oz = 40 ounces.

Now we can apply a change of units, remember that:

1 oz = 28 grams

Then the total amount she needs is:

40 oz = 40*28 g = 1,120 g

So she needs in total 1,120 grams, and in the balance, she already has 720 grams, so the amount that she needs is given by the subtraction:

1,120 g - 720g = 400

To solve the heat equation with non-homogeneous boundary conditions, we transform the non-homogeneous boundary conditions into homogeneous boundary conditions by subtracting the steady-state solution of the heat equation with non-homogeneous boundary conditions.

1. Identify the non-homogeneous boundary conditions in the given heat equation problem.
2. Find the steady-state solution of the heat equation with the given non-homogeneous boundary conditions. The steady-state solution represents the long-term behavior of the system when time approaches infinity.
3. Subtract the steady-state solution from the original heat equation. This transforms the non-homogeneous boundary conditions into homogeneous boundary conditions.
4. Solve the modified heat equation with homogeneous boundary conditions.
5. Add the steady-state solution back to the solution obtained in step 4 to obtain the final solution of the original heat equation with non-homogeneous boundary conditions.

By performing this transformation, we simplify the problem and make it easier to solve, while still maintaining the necessary information to obtain the correct solution.

The speed of the object is 12121 m per week.

What does it mean to do speed?

The object is moving at a speed of 2 centimeters every 7 seconds.

We need to find the speed in m per week.

2 cm = 0.02 m

1 week = 604800 s

7 s =  \(1.65 * 10^{-6} week\)

Speed = distance/time

So,

\(v = \frac{0.02 m}{1.65 * 10^{-6 } week}\)

\(v = 12121.21 m/ week\)

or v = 12121 m/ week

So, the speed of the object is 12121 m per week.

a) Regression equation: y(t) = 19.143t + 70.571

b) The number of social science doctorates has been increasing at a rate of about 19.143 per year since 1990.

c) The slope of the regression line (19.143) is positive but not constant, indicating a decreasing rate of growth.

d) The points would lie exactly on the regression line, indicating a constant rate of growth rather than a slower and slower rate.

(a) To obtain the regression equation and the coefficient of correlation for the number of social science doctorates as a function of time, we can use technology such as a statistical software or calculator.

The coefficient of correlation (r) measures the strength and direction of the linear relationship between the variables.

Using technology, the regression equation and coefficient of correlation (rounded to three decimal places) can be calculated as follows:

Regression equation: y(t) = 19.143t + 70.571

Coefficient of correlation: r = 0.982

To graph the associated points and regression line, plot the given data points for the number of social science doctorates on a scatter plot, with the years (t) on the x-axis and the number of doctorates (y) on the y-axis. Then plot the regression line y(t) = 19.143t + 70.571 on the same graph.

(b) The slope of the regression equation, 19.143, tells us that the number of social science doctorates has been increasing at a rate of about 19.143 per year since 1990.

(c) Judging from the graph, if the points exhibit a concave-up curve rather than a straight line, it suggests that the number of social science doctorates is increasing at a slower and slower rate over time. This is because the slope of the regression line (19.143) is positive but not constant, indicating a decreasing rate of growth.

(d) If the coefficient of correlation (r) had been equal to 1, indicating a perfect positive linear relationship, we could not draw the same conclusion as in part (c).

In that case, the points would lie exactly on the regression line, indicating a constant rate of growth rather than a slower and slower rate.

A correlation coefficient of 1 implies a strong linear relationship, but it does not provide information about the curvature or changing rate of growth.
