Alexi sells apples in her garden at a stand sell each 3. 00 apples what is her total cost how many should she produce
Alexi to consider these factors before deciding how many apples to produce depends on the demand for apples in her area, the size of her garden, and her ability to produce apples efficiently.
How to determine Alexi's total revenue?To determine Alexi's total revenue, we need to know how many apples she plans to sell. Let's assume that Alexi plans to sell X apples.
If Alexi sells each apple for $3, her total revenue will be:
Total revenue = Price per apple x Number of apples sold
Total revenue = $3 X X
Total revenue = $3X
To determine the cost of producing the apples, we need more information about Alexi's production costs. These costs can include expenses such as land, labor, water, and equipment.
Once we know the production costs, we can subtract them from the total revenue to determine Alexi's profit. If the profit is positive, then Alexi will earn money by selling the apples.
In terms of how many apples Alexi should produce, it depends on factors such as the demand for apples in her area, the size of her garden, and her ability to produce apples efficiently. It's important for Alexi to consider these factors before deciding how many apples to produce.

To gather information about the elk population, biologist marked 75 elk. later, they flew over the region and counted 250 elk, of
which 15 were marked. what is the best estimate for the elk population?
es -))
a)
1,200
b)
1,250
c)
1,300
d)
1,350
The best estimate for the elk population is b) 1,250.
To estimate the elk population, you can use the mark and recapture method. The proportion of marked elk to the total marked population should be equal to the proportion of marked elk observed in the sample to the total observed population.
So, (marked elk / total marked population) = (marked elk observed / total observed population)
In this case: (75 / total population) = (15 / 250)
Now, solve for the total population:
75 / total population = 15 / 250
Cross-multiply:
15 * total population = 75 * 250
total population = (75 * 250) / 15
total population = 18,750 / 15
total population = 1,250
The best estimate for the elk population is 1,250 (option b).

(Lesson 8.2) Which statement about the graph of the rational function given is true? (1/2 point)
4. f(x) = 3*-7
x+2
A. The graph has no asymptotes.
B.
The graph has a vertical asymptote at x = -2.
C. The graph has a horizontal asymptote at y =
+
Answer:
B. The graph has a vertical asymptote at
x = -2.
The statement about the graph of the given rational function that is true is: B. The graph has a vertical asymptote at x = -2.
To understand the graph of the rational function f(x) = (3x - 7) / (x + 2), we need to consider its behavior at various points. First, let's investigate the possibility of asymptotes. Asymptotes are lines that the graph approaches but never touches. There are two types of asymptotes: vertical and horizontal.
A vertical asymptote occurs when the denominator of the rational function becomes zero. In this case, the denominator is (x + 2), so we need to find the value of x that makes it zero. Setting x + 2 = 0 and solving for x, we get x = -2. Therefore, the rational function has a vertical asymptote at x = -2 (option B).
To determine if there is a horizontal asymptote, we need to compare the degrees of the numerator and the denominator. The degree of a term is the highest power of x in that term. In the given rational function, the degree of the numerator is 1 (3x) and the degree of the denominator is also 1 (x). When the degrees are the same, we look at the ratio of the leading coefficients, which are 3 (numerator) and 1 (denominator). The ratio of the leading coefficients is 3/1 = 3.
If the ratio of the leading coefficients is a finite value (not zero or infinity), then the rational function will have a horizontal asymptote. In this case, the horizontal asymptote is y = 3 (option C).
Hence the correct option is (b).

Use similar triangles to calculate the height, h cm, of triangle ABE. 10 cm 36 cm D B 20 cm E Optional working I h = Answ cm Search
Answer:
h=24
Step-by-step explanation:
Since the traingles are similar we can calculate the scale factor
20/10 = 2
So the Linear Scale Factor is 2
We can use that to figure out the ratio between the 2 triangles
Since DC = 10 and AE = 20
We cans say that the ratio between DBC and ABE is 2:1
Using this we can see that the ratio of the height is split into 2:1 and the total is 3
Knowing this we can calculate the the heights of both triangles
36 / 3 = 12
Height of small traingle = 1*12 = 12
Height of large triangle = 2*12 = 24

solve quadratic equation 6x²-11x-35= 0 pls needed urgently
Answer:
Step-by-step explanation:To solve the quadratic equation 6x²-11x-35= 0, we can use the quadratic formula:
x = (-b ± sqrt(b² - 4ac)) / 2a
where a, b, and c are the coefficients of the quadratic equation.
In this case, we have:
a = 6
b = -11
c = -35
Substituting these values into the quadratic formula, we get:
x = (-(-11) ± sqrt((-11)² - 4(6)(-35))) / 2(6)
Simplifying this expression:
x = (11 ± sqrt(121 + 840)) / 12
x = (11 ± sqrt(961)) / 12
x = (11 ± 31) / 12
So, we have two solutions:
x = (11 + 31) / 12 = 3
and
x = (11 - 31) / 12 = -5/2
Therefore, the solutions to the equation 6x²-11x-35= 0 are x = 3 and x = -5/2.

A rectangle is changing in such a manner that its length is increasing 5 ft/sec and its width is decreasing 2 ft/sec. at what rate is the area changing at the instant when the length equals 10 feet and the width equals 8 feet
The area of the rectangle is changing at a rate of 20 ft²/sec when the length equals 10 feet and the width equals 8 feet.
How to find the length and width?Let L and W be the length and width of the rectangle, respectively, and let A be the area of the rectangle. Then we have:
L = 10 ft (given)W = 8 ft (given)dL/dt = 5 ft/sec (length is increasing)dW/dt = -2 ft/sec (width is decreasing)We want to find dA/dt, the rate of change of the area A with respect to time t, when L = 10 ft and W = 8 ft.
We know that:
A = L*W
Taking the derivative of both sides with respect to time t, we get:
dA/dt = d/dt (L*W)
Using the product rule of differentiation, we get:
dA/dt = dL/dt * W + L * dW/dt
Substituting the given values, we get:
dA/dt = 5 ft/sec * 8 ft + 10 ft * (-2 ft/sec)
Simplifying, we get:
dA/dt = 40 - 20 = 20 ft²/sec
Therefore, the area of the rectangle is changing at a rate of 20 ft^2/sec when the length equals 10 feet and the width equals 8 feet.

area = [ ? ] m2
The area of the shaded region is 422.8 m², rounded to the nearest tenth.
To find the area of the shaded region, we first need to determine the areas of the two shapes that make up the region. The first shape is a rectangle with dimensions of 18.6 m by 30 m, which has an area of:
Area of rectangle = length x width = 18.6 m x 30 m = 558 m²
The second shape is a semi-circle with a diameter of 18.6 m, which has a radius of 9.3 m. The area of a semi-circle is half the area of a full circle, so we can use the formula for the area of a circle to find the area of the semi-circle:
Area of semi-circle = (1/2) x π x r² = (1/2) x π x 9.3² = 135.2 m²
To find the area of the shaded region, we need to subtract the area of the semi-circle from the area of the rectangle:

An object moving vertically is at the given heights at the specified times. Find the position equation s = 1/2 at^2 + v0t + s0 for the object.
At t = 1 second, s = 136 feet
At t = 2 seconds, s = 104 feet
At t = 3 seconds, s = 40 feet
The position equation for the object is: s = -80t^2 + 208t + 88, where s is the position of the object (in feet) at time t (in seconds).
We can use the position equation s = 1/2 at^2 + v0t + s0 to solve for the unknowns a, v0, and s0.
At t = 1 second, s = 136 feet gives us the equation:
136 = 1/2 a(1)^2 + v0(1) + s0
136 = 1/2 a + v0 + s0 ----(1)
At t = 2 seconds, s = 104 feet gives us the equation:
104 = 1/2 a(2)^2 + v0(2) + s0
104 = 2a + 2v0 + s0 ----(2)
At t = 3 seconds, s = 40 feet gives us the equation:
40 = 1/2 a(3)^2 + v0(3) + s0
40 = 9/2 a + 3v0 + s0 ----(3)
We now have a system of three equations with three unknowns (a, v0, s0). We can solve this system by eliminating one of the variables. We will eliminate s0 by subtracting equation (1) from equation (2) and equation (3):
104 - 136 = 2a + 2v0 + s0 - (1/2 a + v0 + s0)
-32 = 3/2 a + v0 ----(4)
40 - 136 = 9/2 a + 3v0 + s0 - (1/2 a + v0 + s0)
-96 = 4a + 2v0 ----(5)
Now we can solve for one of the variables in terms of the others. Solving equation (4) for v0, we get:
v0 = -3/2 a - 32
Substituting this into equation (5), we get:
-96 = 4a + 2(-3/2 a - 32)
-96 = 4a - 3a - 64
a = -160
Substituting this value of a into equation (4), we get:
-32 = 3/2(-160) + v0
v0 = 208
Finally, substituting these values of a and v0 into equation (1), we get:
136 = 1/2(-160)(1)^2 + 208(1) + s0
s0 = 88
Therefore, the position equation for the object is:
s = -80t^2 + 208t + 88
where s is the position of the object (in feet) at time t (in seconds).

Antonio's weight after 5 weeks was 202.34 pounds, and it took him 19 weeks to weigh in at 161.05 pounds.
To find Antonio's weight after 5 weeks, we can simply substitute t = 5 into the given exponential function:
W(5) = 235(0.985)⁵
W(5) ≈ 209.88 pounds
So his weight after 5 weeks was approximately 209.88 pounds. To find how long it took him to weigh in at 161.05 pounds, we can set the function equal to 161.05 and solve for t:
161.05 = 235(0.985)ᵗ

Use the given terms to generate a recursive rule. Sequence:13,15,23,55,183
To generate a recursive rule for the sequence 13, 15, 23, 55, 183, we need to identify the pattern in the sequence.
Looking at the differences between each term, we can see that:
15 - 13 = 2
23 - 15 = 8
55 - 23 = 32
183 - 55 = 128
So the differences are increasing by a factor of 4 each time.
Using this pattern, we can create a recursive rule:
a(1) = 13
a(n) = a(n-1) + 4^(n-2)
So for example,
a(2) = a(1) + 4^(2-2) = 13 + 1 = 14
a(3) = a(2) + 4^(3-2) = 14 + 4 = 18
a(4) = a(3) + 4^(4-2) = 18 + 16 = 34
a(5) = a(4) + 4^(5-2) = 34 + 64 = 98
a(6) = a(5) + 4^(6-2) = 98 + 256 = 354

Answer:
250 people like the summer season, 200 people like the winter season, and 50 people like both seasons.
Step-by-step explanation:
Let's assume that the number of people who like both summer and winter is "x". We know that:
- 200 people like summer only
- 150 people like winter only
- The number of people who don't like either season is twice the number of people who like both seasons
To find the value of "x", we can use the fact that the total number of people who don't like either season is twice the number of people who like both seasons:
150 - 2x = 2x
Solving for "x", we get:
x = 50
150 people like the winter season, 200 people like the summer season.
The number of people who don't like summer and winter is twice the number of people who like both seasons.
The number of people who like both the seasons= x
The number of people like summer 200
The number of people who like winter 150
The number of people who don't like summer and winter is twice the number of people who like both seasons.
To find the value of x, we can use the equation:
150-x= 2x
150= 3x
x= 50

What is division?
A division is one of the fundamental mathematical operations that divides a larger number into smaller groups with the same number of components. How many total groups will be established, for instance, if 20 students need to be separated into groups of five for a sporting event? The division operation makes it simple to tackle such issues. Divide 20 by 5 in this case. 20 x 5 = 4 will be the outcome. There will therefore be 4 groups with 5 students each. By multiplying 4 by 5 and receiving the result 20, you may confirm this value.
Let's start by finding out the weight of pears the farmer sold.
Weight of pears = 3/5 x 7.9 kg = 4.74 kg
To find the weight of apples, we can subtract the weight of pears from the total weight:
Weight of apples = Total weight - Weight of pears
Weight of apples = 7.9 kg - 4.74 kg
Weight of apples = 3.16 kg
Therefore, the farmer sold 3.16 kilograms of apples at the farmers market.

The worth of the computer after depreciating for 3 years is $749.77, under the condition that a rate of 16% per year was applied.
Then the derived formula for evaluating depreciation
Depreciation = (Asset Cost – Residual Value) / Life-Time Production × Units Produced
Then,
Asset Cost = $1,495
Residual Value = 0 (assuming the computer has no resale value after 3 years)
Life-Time Production = 3 years
Units Produced = 1
Hence, the depreciation rate
[tex]Depreciation Rate = (1 - (Residual Value / Asset Cost)) ^{ (1 / Life-Time Production) - 1}[/tex]
[tex]Depreciation Rate = (1 - (0 / 1495))^{(1/3-1)}[/tex]
Depreciation Rate = 16%
Now to evaluate the value of the computer after three years of depreciation at a rate of 16% per year, we can apply the derived formula
Value of Asset After Depreciation = Asset Cost × (1 - Depreciation Rate) ^ Life-Time Production
Value of Asset After Depreciation = $1,495 × (1 - 0.16)³

To find the volume of the rectangular prism, we can use the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.
Since there are three pairs of congruent faces, we can deduce that the areas of the three pairs of faces represent the three dimensions of the rectangular prism. The areas are 9, 25, and 49 square meters, which are the squares of the sides' lengths.
Take the square root of each area to find the corresponding side lengths:
√9 = 3 meters
√25 = 5 meters
√49 = 7 meters
Now, apply the formula to find the volume:
V = lwh = 3 × 5 × 7 = 105 cubic meters.
The volume of the rectangular prism is 105 cubic meters.

The smaller of two similar rectangles has dimensions 4 and 6. Find the dimensions of the larger rectangle if the ratio of
the perimeters is 2 to 3.
O 6 by 9
2/3
by 4
12 by 12
O8 by 18
Answer:
The smaller rectangle has perimeter
2(4 + 6) = 2(10) = 20, so the larger rectangle will have perimeter 30. The dimensions of the larger rectangle are 6 by 9 since 2(6 + 9) = 2(15) = 30.
How do I do this step by step
Answer:
Step-by-step explanation:
Let's call the total volume of the container "V".
We know that the container was originally 15% full, so the amount of water in the container was 0.15V.
When 48 litres of water was added, the new volume of water in the container became 0.15V + 48.
We also know that the container is now 75% full, so the new volume of water in the container must be 0.75V.
We can set up an equation to solve for V:
0.15V + 48 = 0.75V
Subtracting 0.15V from both sides:
48 = 0.6V
Dividing both sides by 0.6:
V = 80
So the container can hold 80 litres of water when it is full.

the perimeter of an isosceles triangle is 12x^2-5x +4 cm find the length of one of its equal sides
Answer:
4x² - x + 2--------------------------
Let the equal sides be both marked as ?
Use the perimeter formula to determine one of the equal sides.
P = 2(?) + x(4x - 3)Substitute the expression for the perimeter and find the value of ?
12x² - 5x + 4 = 2(?) + x(4x - 3)12x² - 5x + 4 = 2(?) + 4x² - 3x2(?) = 12x² - 5x + 4 - 4x² + 3x2(?) = 8x² - 2x + 4? = 4x² - x + 2Hence the length of each of equal sides is 4x² - x + 2.
Find the product. Assume that no denominator has a value of 0.
6r+3/r+6 • r^2 + 9r +18/2r+1
Answer:
Step-by-step explanation:
We can simplify the fractions first:
(3r + 9)(r+6) / (r+6) = 3r + 9
6r + 3 / (r + 6) = 3(2r + 1) / (r + 6)
(r^2 + 9r + 18) / (2r + 1) = (r^2 + 6r + 3r + 18) / (2r + 1) = [(r+3)(r+6)] / (2r + 1)
So the expression becomes:
[3(2r + 1) / (r + 6)] * [(r+3)(r+6) / (2r + 1)]
We can now cancel out the common factors:
[3 * (r+3)] = 3r + 9
Therefore, the simplified product is:
(3r + 9)(r+6) / (r+6) = 3r + 9
