you operate a tour service that offers the following rates: $600 per person if 30 people (the minimum number to book the tour) go on the tour. for each additional person, up to a maximum of 130 people total, the rate per person is reduced by $3. it costs $7380 (a fixed cost) plus $390 per person to conduct the tour. how many people does it take to maximize your profit?
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

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

Answer:
3.75 and B
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
To explain how the formula for area, A=bh
, can be used to derive the formula for the area of a circle, start by taking a circle, dividing it into small pizza shaped slices, and laying the slices out as shown.
The smaller the slices are, the less curvature and the closer to a parallelogram the shape becomes.
The base of the parallelogram, in terms of the circle, is
, and the height of the parallelogram is
.
Area is base times height, so multiply the base and the height together.
Now we have the formula area =
.
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.

Part 1
Point B has coordinates (3,1). The x-coordinate of point A is -3. The distance between point A and point B is units. What are the possible coordinates of point A?
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)).

How to find the residual plot ?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

Therefore , the solution of the given problem of triangle comes out to be h/s = h/√(h² - s²)..
A triangle is exactly what?If a polygon has at least one additional segment, it is a hexagon. Its form is a straightforward rectangle. Something like this can only be distinguished from a regular triangular by edges A and B. Euclidean geometry only creates a portion of the cube, despite the precise collinearity of the borders. A triangular has three sides and three angles.
Here,
Triangle ABC and triangle ACD are both right triangles with a common hypotenuse, as shown by the given diagram.
Let's write the lengths of the sides AB or AD as s and the hypotenuse AC as h. (since both triangles have a common side with length s).
The Pythagorean formula can now be used to determine the length of each triangle's third side:
Triangle ABC's third side's length (BC) can be calculated using this formula:
=> BC = √(h² - s²).
The third side's (CD) length in the triangle ACD is also determined by:
=> CD = √(h² - s²).
By dividing each triangle's hypotenuse's (h) length by one of its sides' (s) lengths, the following result is obtained:
In the triangular ABC,
=> h/s = h/ √(h² - s²).
In the triangular ACD

an a-frame tent is in the shape of an isosceles triangle. the base of the triangle is 7 ft and the two congruent sides are each 6 ft. what is the height of the tent
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

The product of 2 and 1 3/6 can be expressed as either 18/6 or 3
The product of 2 and 1 3/6 can be found by multiplying 2 by the mixed number 1 3/6. To do this, we need to convert the mixed number to an improper fraction, then multiply it by 2. Here are two possible expressions that are equal to the product of 2 and 1 3/6
Improper fractions
2 x 1 3/6 = 2 x (1 + 3/6) = 2 x (6/6 + 3/6) = 2 x 9/6 = 18/6
Therefore, the product of 2 and 1 3/6 is equal to 18/6.
Decimals
We can also convert the mixed number 1 3/6 to a decimal and then multiply it by 2. To convert the mixed number to a decimal, we divide the numerator (3) by the denominator (6), which gives us 0.5. Then we add the whole number (1) to get 1.5.
2 x 1.5 = 3

= ∫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.
