The height of one of the triangular faces of the pyramid is approximately 21.4 inches.

To find the height of one of the triangular faces of the pyramid, we need to use the formula for the surface area of a pyramid:
Surface Area = ½ × Perimeter of Base × Slant Height + Base Area
Since the base of the pyramid is a square with a side length of 10 inches, its perimeter is 4 times the length of one of its sides, which is 4 × 10 = 40 inches.
We know that the surface area of the pyramid is 540 square inches, and we know the base area is the area of a square with a side length of 10 inches, which is 10 × 10 = 100 square inches. So, we can substitute these values into the formula and simplify:
540 = ½ × 40 × Slant Height + 100
440 = 20 × Slant Height

Slant Height = 22 inches
Now we can use the Pythagorean theorem to find the height of one of the triangular faces. The slant height, the height of the pyramid, and half the length of the base form a right triangle. We know that the length of half the base is 5 inches, so:
(Height of Pyramid)² + (5 inches)² = (22 inches)²
(Height of Pyramid)² = 484 - 25
(Height of Pyramid)² = 459
Height of Pyramid ≈ 21.4 inches

The radius of the circle is approximately 10.17 units (rounded to two decimal places).

To find the radius of the circle, we need to use the formula that relates the central angle to the length of the arc and the radius of the circle. The formula is given as:

arc length = radius x central angle

In this case, the arc length is given as 24.4 and the central angle is given as 2.4 radians. Substituting these values in the formula, we get:

24.4 = r x 2.4

Solving for r, we get:

r = 24.4 / 2.4

r ≈ 10.17

The average rate of change of a function between two points is equal to the difference of the function values at those two points divided by the difference of the two x-coordinates. This can be written as:
Average rate of change = (f(b) - f(a))/(b - a)

where a and b are the endpoints of the interval.
The instantaneous rate of change at the endpoints of the interval is the derivative of the function evaluated at the two points. This can be written as:
Instantaneous rate of change at x = a: f'(a)
Instantaneous rate of change at x = b: f'(b)
The average rate of change is typically a good estimate of the instantaneous rate of change within the interval. However, the instantaneous rate of change at the endpoints of the interval is not necessarily the same as the average rate of change, as the function might be changing at a different rate near the endpoints. It is important to compare the average rate of change with the instantaneous rates of change at the endpoints of the interval in order to get an accurate understanding of the rate of change of the function over the entire interval.

Step-by-step explanation:

U add 4+5=9 so that is one lap

then take 9*5=45 and that would be 5 laps

Answer:

45

Step-by-step explanation: first we want to find out the time it takes to do one full lap of skiing. in order to do this you have to add 4 to 5. we do this because if we start at the bottom of the hill we have to ride 4 min up to the top then 5 min to get back to the bottom. so in all it will 9 min to do one full lap. because we want to find out how long it will take to do 5 laps we do 9x5=45

In a proportional relationship between two quantities, the constant of proportionality, often denoted by the letter "k," represents the value that relates the two quantities. The equation y = kx is the standard form for expressing a proportional relationship, where "y" and "x" are the variables representing the two quantities.

Here's a breakdown of the components in the equation:

y: Represents the dependent variable, which is the quantity that depends on the other variable. It is usually the output or the variable being measured.

x: Represents the independent variable, which is the quantity that determines or influences the other variable. It is typically the input or the variable being controlled.

k: Represents the constant of proportionality. It indicates the ratio between the values of y and x. For any given value of x, multiplying it by k will give you the corresponding value of y.

The constant of proportionality, k, is specific to the particular proportional relationship being considered. It remains constant as long as the relationship between x and y remains proportional. If the relationship is linear, k also represents the slope of the line.

For example, if we have a proportional relationship between the distance traveled, y, and the time taken, x, with a constant of proportionality, k = 60 (representing 60 miles per hour), the equation would be y = 60x. This equation implies that for each unit increase in x (in hours), y (in miles) will increase by 60 units.

Answer:

$4,420.00 ≤ t ≤ $4,834.38

Step-by-step explanation:

Since yearly employee wages range from 32 to 35%, lets calculate what those percentages are in dollars:

32%:  ($165,750)*(0.32) = $53,040/year

35%:  ($165,750)*(0.35) = $58,012.5/year

To find the average monthly budget, divide the yearly budget by 12 months

32%:   $53,040/year*(1 year/12 months) = $4,420/month

35%:  ($58,012.5/year*(1 year/12 months) = $4,834.4/month

t ranges from $4,420/month to $4,834.4/month

Step-by-step explanation:

The distance between the two towers is 30 meters, and the height of the second tower (Tower B) is 90 meters.

We have two towers. Let's call the first tower Tower A, and the second tower Tower B. The height of Tower A is given as 30 meters. The angle of elevation of the top of Tower A from the foot of Tower B is 60 degrees. The angle of elevation of the top of Tower B from the foot of Tower A is 30 degrees. Our goal is to find the distance between the two towers and the height of Tower B.

In triangle ABC, where A is the foot of Tower A, B is the top of Tower B, and C is the top of Tower A:

tan(30 degrees) = AB / BC

Since tan(30 degrees) = 1 / √3, we can rewrite the equation as:

1 / √3 = AB / BC

Cross-multiplying, we get:

BC = AB * √3

In triangle ABC:

tan(60 degrees) = AC / BC

Since tan(60 degrees) = √3, we can rewrite the equation as:

√3 = AC / BC

Substituting the value of BC from Step 3:

√3 = AC / (AB * √3)

Cross-multiplying, we get:

AC = AB * 3

We have two equations:

BC = AB * √3

AC = AB * 3

Dividing equation 2 by equation 1:

AC / BC = 3 / √3

Simplifying, we get:

√3 = 3 / √3

Cross-multiplying, we get:

3 = 3

Since 3 = 3 is a true statement, we can conclude that the two towers are at the same distance as their heights. Therefore, the distance between the two towers is 30 meters.

Using the value of the distance between the towers (30 meters), we can substitute this value into one of the previous equations to find the height of Tower B. Let's use equation 2:

AC = AB * 3

Substituting AB with the distance (30 meters):

AC = 30 * 3

Simplifying, we find:

AC = 90 meters

Therefore, the height of Tower B is 90 meters.

Answer:

1684.8 cubic units

Step-by-step explanation:

In oblique cylinder the height (altitude) is measured from the opposite base to the base of the cylinder, but it lies outside. We can find the height using Pythagoras theorem.

       h + 7² = 13²

              h²= 169 - 49

              h² = 120

               h = √120

                h = 10.95 units

radius = r = 7 units

\(\boxed{\text{\bf Volume of oblique cylinder = $\bf\pi r^2h$} }\)

                                                    = 3.14 * 7 * 7 * 10.95

Using the law of sines, supposing C = 30º, the angle of each observer with the sailboat is:

Suppose we have a triangle in which:

The lengths and the sine of the angles are related according to the following rule:

\(\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}\)

The measure of angle B is found as follows:

sin(B)/10 = sin(C)/20

sin(B)/10 = 0.5/20 (sin(C) = 0.5)

sin(B) = 5/20

sin(B) = 0.25

B = arcsin(0.25)

B = 14º.

The measure of angle A is found as follows:

sin(A)/25 = sin(C)/20

sin(A)/25 = 0.5/20 (sin(C) = 0.5)

sin(A) = 12.5/20

sin(A) = 0.625

A = arcsin(0.625)

A = 136º.

The problem is incomplete, hence we suppose that the angle C is of 30º and problem asks for the angle measure of each angle.

Answer:

156,000

Step-by-step explanation:

291 divided by 97 is 3. 52,000 x 3 = 156,000.

Population will be 6 times of present population in 291 years.

The number of people in the city at a particular time is called population of the city.

Present population of the city = 52000

According to the problem, Population doubles in size in every 97 years.

After 97 years, the population = Double of present population

                                                  = 2 × 52000 = 104000

Population in 97 years = 104000

Population in 1 year = \(\frac{104000}{97}\)

So, population in 291 years =  \(\frac{104000}{97}\)× 291 = 104000×3 = 312000

Population in 291 years from now = \(\frac{312000}{52000}\) = 6 times
