The height of the tent is approximately 4.87 feet.

To find the height of the tent, we need to first determine the length of the altitude (perpendicular line) drawn from the apex (top point) of the triangle to the base. Let's call this length "h".

We can use the Pythagorean theorem to find "h". Let's draw a line from the apex of the triangle to the midpoint of the base, which will split the isosceles triangle into two congruent right triangles. Then we have

h^2 + (7/2)^2 = 6^2

h^2 + 49/4 = 36

h^2 = 36 - 49/4

h^2 = 95/4

h = sqrt(95)/2

h ≈ 4.87 ft

]]] explanation:

67 people can maximize the profit.

Let's aasume that x represent the number of people.

so, the number of people on the tour = x + 50

The cost function would be:

C = 6000 + 32x

and the revenue:

R = (200 - 2x)(50 + x)

R = 10000 - 100x + 200x - 2x^2

R = 10000 + 100x - 2x²

So, the profit would be:

P = R - C

P = 10000 + 100x - 2x² - 6000 - 32x

P = 4000 + 68x - 2x²

Now we take the derivative of profit function:

P' = 68 - 4x

Consider P'(x) = 0

68 - 4x = 0

4x = 68

x = 17

So, the number of people on tour: 50+17 = 67

This means that 67 people can maximize the profit.

and the profit would be:

P = 4000 + (68 × 17) - (2 × 17²)

P = $4578

In Linear equation, 5/8 golf balls per ounce are the number of golf balls per Ounce.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                          Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Equations with power 1 variables are known as linear equations. One example with only one variable is where ax+b = 0, where a and b are real values and x is the variable.

Number of golf balls (n) = 20

Total weight (w) = 32 ounces

total weight = number of balls (n) * weight of 1 golf ball

∴ weight of 1 golf ball = w/n =32/20 ounces

⇒ the weight distribution is 1.6 ounce per golf ball

Now, apply unitary method :

32 ounces is total weight of 20 golf balls

∴ 1 ounce amounts to 20/32 golf balls

The double integral of sin(xy) over the rectangle r equals 1 when a is approximately equal to 0.986, with 0 ≤ a ≤ π.

The iterated integral to compute the double integral over the rectangle r = {(x,y) : 0 ≤ x ≤ π, 0 ≤ y ≤ a} of sin(xy) is given by:

∫∫r sin(xy) dA = ∫₀^a ∫₀^π sin(xy) dx dy

Integrating with respect to x first, we have:

∫₀^a ∫₀^π sin(xy) dx dy = ∫₀^a [-cos(πy) + cos(0)] dy

= ∫₀^a (1 - (-1)^n) dy

= a - (a/π)sin(πa)

For what values of a is ∫∫r sin(xy) dA equal to 1?

We need to solve the equation:

a - (a/π)sin(πa) = 1

Multiplying both sides by π, we get:

aπ - a sin(πa) = π

Now, let f(a) = aπ - a sin(πa) - π. We need to find the values of a such that f(a) = 0.

Using numerical methods, we can find that there is only one solution in the interval [0,π], which is approximately a = 0.986.

Therefore, the double integral of sin(xy) over the rectangle r equals 1 when a is approximately equal to 0.986, with 0 ≤ a ≤ π.

Step-by-step explanation:

for the first one if the actual is 48 feet, and the image is 12.8, divide both by the image(12.8). The value you have for the image should then become one centimeter, therefore the value you have for the parking lot is the amount of feet/1cm. For the second image, its the same idea. In this case you want to know how tall the scale is, so divide by the amount of meters(just as 6/2=3 and 6/3=2 the real value/scale value=representation of 1 unit and real value/representation of 1 unit = scale value). You get 12.5, however that is per 1 unit, so multiply by five since(the value you get by simply dividing is the answer IF 30 meters were represented in the scale by 1centimeter, but its represented by 5 so you multiply by five)You get 63.5

The two sides of the triangle are equal the triangle is an isosceles triangle.

Triangles with two equal sides are known as isosceles triangles. Triangles are three-sided polygons that can be categorised as equilateral, isosceles, or scalene depending on how long their sides are.

The uneven side of this triangle is referred to as the base since the other two sides are equal in it. The triangle's two equal sides are always opposing equal angles. An isosceles triangle's height is calculated from its base to its vertex (topmost point). The third angle of a right isosceles triangle is 90 degrees.

The coordinates of the triangle are J(-2, 4), K(8, 4) and L (6, -2).

Using the distance formula we have:

The distance between J and K: √((8 - (-2))² + (4 - 4)²) = 10

The distance between K and L: √((6 - 8)² + (-2 - 4)²) = 6.324

The distance between L and J: √((-2 - 6)² + (4 - (-2))²) = 10

The graph that shows the residual plot for the height and weight of the 10 players is B. Graph B.

To find the residual plot, you need to use the data on height and weight of 10 players shown on the table, and compare it to figures you get from the formula given of y = -146.7 + 4.76 x.

Doing this, we find two residuals being:

x = 68

Predicted y = -146.7 + 4.76(68) = 175.88

Actual y = 170

Residual = Actual y - Predicted y = 170 - 175.88 = -5.88

x = 70

Predicted y = -146.7 + 4.76(70) = 185.3

Actual y = 185

Residual = Actual y - Predicted y = 185 - 185.3 = -0.3

These points of (68, - 5.88) and ( 70, - 0.3) tally with Graph B so this is the residual plot.

We have two possible values for y, we have two possible Coordinates for point A: (-3, 1 + √((units)² - (3 - (-3))²)) and (-3, 1 - √((units)² - (3 - (-3))²)).

Here are the terms and steps we'll use in the solution:

1. Point B coordinates: (3, 1)
2. Point A x-coordinate: -3
3. Distance formula: √((x2 - x1)² + (y2 - y1)²)

Let's find the possible coordinates of point A:

Step 1: We know the x-coordinate of point A is -3, so its coordinates will be in the form (-3, y).

Step 2: Apply the distance formula to find the distance between point A (-3, y) and point B (3, 1):

Distance = √((3 - (-3))² + (1 - y)²)

Step 3: Square the distance equation to eliminate the square root:

Distance² = (3 - (-3))² + (1 - y)²

Step 4: Plug in the given distance value and solve for y:

(units)² = (3 - (-3))² + (1 - y)²

Step 5: Solve for (1 - y)²:

(1 - y)² = (units)² - (3 - (-3))²

Step 6: Take the square root of both sides:

1 - y = ±√((units)² - (3 - (-3))²)

Step 7: Solve for y:

y = 1 ±√((units)² - (3 - (-3))²)

Since we have two possible values for y, we have two possible coordinates for point A: (-3, 1 + √((units)² - (3 - (-3))²)) and (-3, 1 - √((units)² - (3 - (-3))²)).

bh, where b is the base and h is the height of the parallelogram.

In the case of the circle, the base of the parallelogram is the circumference of the circle, which is equal to 2πr, where r is the radius of the circle. The height of the parallelogram is the distance from the center of the circle to the edge of the circle, which is also the radius r. Therefore, we have:

b = 2πr

h = r

Substituting these values into the formula for the area of a parallelogram, we get:

Area = bh = (2πr)(r) = 2πr^2

So the formula for the area of a circle is derived from the formula for the area of a parallelogram by using the circumference of the circle as the base and the radius of the circle as the height.

The volume of 11 gallons is 50 litres.

The volume of 40 litres is 8.8 litres.

The capacity of the tank in gallons is 26.7 gallons

The graph of a proportional relationship is always a straight line through the origin.

Therefore, the graph is a relationship between the variables volumes in litres and gallons. The litres is on the y axis while the gallons is on the x axis.

Hence, let's use the graph to convert the volumes.

11 gallons = 50 litres

40 litres = 8.8 litres

A tank has a volume of 120, 000 cm cube.

1 litre  = 1000 cm³

The capacity of the tank in gallons can be found as follows:

1000 cm³ = 1 litres

120,000 cm³= ?

volume in litres = 120,000 / 1000

volume in litres = 120 litres

From the graph,

36 litres = 8 gallons

120 litres = ?

cross multiply

volume in gallons = 120 × 8  / 36
