The profits of a company are found by subtracting the company's costs from its revenue. If a company's cost can be modeled by 14x-0.0002xsquared, what is an expression for the profit
An expression for the profit of the company is 26x - 0.0002x^2 - 120,000.
To find the expression for the profit of a company, we need to subtract the cost from the revenue.
The cost of the company is given by the expression 14x + 120,000, where x represents the quantity of the product being produced or sold.
The revenue of the company is given by the expression 40x - 0.0002x^2, where x represents the quantity of the product being produced or sold.
To find the profit, we subtract the cost from the revenue:
Profit = Revenue - Cost
Profit = (40x - 0.0002x^2) - (14x + 120,000)
To simplify the expression, we distribute the negative sign:
Profit = 40x - 0.0002x^2 - 14x - 120,000
Combining like terms:
Profit = (40x - 14x) - 0.0002x^2 - 120,000
Simplifying further:
Profit = 26x - 0.0002x^2 - 120,000
Therefore, an expression for the profit of the company is 26x - 0.0002x^2 - 120,000.
Final answer:
The profit of a company is the difference between its total revenue and costs, and can be calculated using the formula P = R - (14x - 0.0002x²), where P is profit, R is revenue, and x is the number of units.
Explanation:
To calculate the expression for the profit of the company, we need to find the difference between the total revenue and the total cost.
Given the cost can be modeled by 14x - 0.0002x2, and assuming the revenue is R, the profit P can be represented as:
P = R - (14x - 0.0002x²)
If we are given a specific value for the revenue, we would substitute it in place of R to find an explicit expression for P. For instance, if the revenue is $200,000, the profit formula would be:
P = $200,000 - (14x - 0.0002x²)
It's important to note that the profit decreases as the cost increases, and when costs exceed revenue, the company experiences a loss.

AB is a diameter of a circle, center O. C is a point on the circumference of the circle, such that
CAB = 26°
What is the size of CBA?
A. 26
B. 45
C. 64
D. 74
Given:
AB is the diameter of a circle.
m∠CAB = 26°
To find:
The measure of m∠CBA.
Solution:
Angle formed in the diameter of a circle is always 90°.
⇒ m∠ACB = 90°
In triangle ACB,
Sum of the angles in the triangle = 180°
m∠CAB + m∠ACB + m∠CBA = 180°
26° + 90° + m∠CBA = 180°
116° + m∠CBA = 180°
Subtract 116° from both sides.
116° + m∠CBA - 116° = 180° - 116°
m∠CBA = 64°
The measure of m∠CBA is 64°.
The size of angle CBA is 128 degrees.
Explanation:To find the size of CBA, we can use the fact that angles in a triangle add up to 180 degrees. Since AB is a diameter, it divides the circle into two semicircles, and angle CAB is an inscribed angle that is half the measure of the central angle.
Therefore, m(CAB) = 26 degrees, and m(CBO) = 2 * 26 = 52 degrees. Since angle CBA is an exterior angle of triangle CBO, it is equal to the sum of the remote interior angles, which is 180 - 52 = 128 degrees.
So, the size of CBA is 128 degrees. The answer is option D. 74.

Answer: 205 buttons
Step-by-step explanation:
Garcia has 2 button collections. One has 321 buttons in it. The other has 704 buttons. The total button collection will be:
= 321 + 704 = 1025
Since she wants to divide it equally among 5 friends, we divide 1025 by 5. This will be:
= 1025 ÷ 5
= 205
Each friend will get 205 buttons.
Answer:
Each friend will receive 205 buttons
Step-by-step explanation:
In this question, we are tasked with calculating the number of buttons each of 5 Garcia's friend will receive
Firstly, we will need to find the total number of buttons available
That would be 321 + 704 = 1025 buttons
Now to find the distribution per friend, we simply divider the total by 5
That would be 1025 buttons ÷ 5 = 205 buttons
This means that each of the five friends will receive 205 buttons each

Step-by-step explanation:
Sue makes 50 litres of green paint by mixing litres of yellow paint and litres of blue paint in the ratio 1:4. Yellow paint is sold in 5 litre tins and each tin of yellow paint costs £38. Blue paint is sold in 10 litre tins and each tin of blue paint costs £58. Sue sells all the green paint she makes in 10 litre tins at £89.32 per tin. Work out Sue's percentage profit on each tin of green paint she sells.
Answer:
Sue's percentage profit = 9% on each tin of green paint she sells.
Step-by-step explanation:
Litres of green paints mixed = 50 litres
Ratio of litres of yellow paint and litres of blue paint = 1:4.
To determine the litres of yellow paint, we say:
[tex]yellow \: paint = \frac{1}{4} \times 50 = 10 \: litres[/tex]
To determine the litres of blue paint, we say:
[tex]blue \: paint = \frac{4}{5} \times 50 = 40 \: litres[/tex]
Since yellow paint is sold in 5 litres per tin and each tin cost £38; she has 10 litres of yellow paint in all. That implies that she has 10/5 = 2 tin of yellow paint. If one tin cost £38; 2 tin cost 2 × £38 = £76
Similarly,
Since blue paint is sold in 10 litres per tin and each tin cost £58; she has 40 litres of blue paint in all. That implies that she has 40/10 = 4 tin of blue paint. If one tin cost £58; 4 tin cost 4 × £58 = £232
Total cost of yellow and blue paints = £232 + £76
= £308
Since Sue sells all the green paint she makes in 10 litre tins at £89.32 per tin and she has 50 litres in all; we say: 50/10 litres = 5 tins = 5 × £89.32 = £446.60.
Thus, selling price of the green paint = £446.60
[tex]profit \: \% = \frac{selling \: price - cost \: price}{cost \: price} \times \frac{100}{1} [/tex]
[tex]profit \: \% = \frac{446.60 - 308}{308} \times \frac{100}{1} [/tex]
[tex]profit \: \% = \frac{138.60}{308} \times \frac{100}{1} [/tex]
[tex]profit \: \% = 0.45 \times 100[/tex]
[tex]profit \: \% = 45\%[/tex]
Sue's percentage profit for selling all the tins of green paint is 45%, having sold 5 tins. Therefore, Sue's percentage profit for selling each of the paint will be:
[tex]profit \: \% \: on \: each \: green \: tin = \frac{45}{5} = 9\%[/tex]
Hence, Sue's percentage profit for selling each tin of green paint is 9%.
Proof
9% × 5 tins of green paint = 45%
Final answer:
Sue's percentage profit on each tin of green paint she sells is approximately 44.94%. This is calculated by finding the total cost of inputs, subtracting from the total sales revenue, and then finding the profit ratio to the cost.
Explanation:
To calculate Sue's percentage profit on each tin of green paint she sells, we need to first determine the cost of producing the green paint and then subtract that cost from the selling price. The green paint is produced in a ratio of 1:4 yellow to blue paint, making 50 litres total. Therefore, Sue uses 10 litres of yellow paint and 40 litres of blue paint to make 50 litres of green paint.
Yellow paint costs £38 for a 5-litre tin, so two tins are needed (costing £76 total) to get the required 10 litres. Blue paint costs £58 for a 10-litre tin, so four tins are needed (costing £232 total) to get 40 litres. This brings the total cost to £308 for 50 litres of green paint.
Sue sells her green paint at £89.32 per 10-litre tin. Therefore, for 50 litres, she gets 5 tins x £89.32 = £446.60.
The profit Sue makes is the selling price minus the cost price, which is £446.60 - £308 = £138.60. To find the percentage profit per tin, divide the profit by the cost and multiply by 100:
(£138.60 / £308) x 100 = 44.94%
Therefore, Sue's percentage profit on each tin of green paint she sells is approximately 44.94%.
About 1/4 of all adults in the United States have type O+ blood. If three randomly selected adults donate blood, find the probability of each of the following events. (Round your answers to four decimal places.) (a) All three are type O+. 0.0156 Correct: Your answer is correct. (b) None of them is type O+. 0.4219 Correct: Your answer is correct. (c) Two out of the three are type O+.
Answer:
a) 0.0156
b) 0.4219
c) 0.1406
Step-by-step explanation:
We are given the following information:
We treat adult having type O+ blood as a success.
P(Adult have type O+ blood) = 0.25
Then the number of adults follows a binomial distribution, where
[tex]P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}[/tex]
where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 3
a) All three are type O+
[tex]P(x =3)\\= \binom{3}{3}(0.25)^3(1-0.25)^0\\= 0.0156[/tex]
b) None of them is type O+
[tex]P(x =0)\\= \binom{3}{0}(0.25)^0(1-0.25)^3\\= 0.4219[/tex]
c) Two out of the three are type O
[tex]P(x =2)\\= \binom{3}{2}(0.25)^2(1-0.25)^1\\= 0.1406[/tex]
Using the principle of binomial probability, the probability o the required events are :
All three O positive = 0.0156None O positive = 0.42192 O positive = 0.1406Recall :
P(x = x) = nCx * p^x * q^(n-x) p = probability of success = 1/4 = 0.25q = 1 - p = 1 - 0.25 = 0.75n = number of trials = 3
A.) Probability that all 3 are O+ :
x = 3
P(x = 3) = 3C3 × 0.25³ × 1 = 0.0156
B.) Probability that none 3 are O+
x = 0
P(x = 3) = 3C0 × 1 × 0.75³= 0.4219
C.) Probability that 2 out of the three are O+
x = 2
P(x = 2) = 3C2 × 0.25² × 0.75¹ = 0.1406
Therefore, the required probabilities are : 0.0156, 0.4219 and 0.1406 respectively.

Step-by-step explanation:
1. We have the opposite and adjacent sides here for angle 31 degrees. So we need to use tangent, which is opposite / adjacent:
[tex]tan(31)=16/x[/tex]
[tex]x=16/(tan(31))[/tex] ≈ 26.6 units
2. We have the opposite and hypotenuse sides here for angle 43 degrees. So we need to use sine, which is opposite / hypotenuse:
[tex]sin(43)=x/18[/tex]
[tex]x=18*sin(43)[/tex] ≈ 12.3 units
3. We have the adjacent and hypotenuse sides here for angle 53 degrees. So we need to use cosine, which is adjacent / hypotenuse:
[tex]cos(53)=14/x[/tex]
[tex]x=14/(cos(53))[/tex] ≈ 23.3 units
4. We have the adjacent and hypotenuse sides here for angle 33 degrees. So we need to use cosine, which is adjacent / hypotenuse:

Spencer made a quilt for his cousin's doll. The quilt had a 7x7 array of different color square patches. If each patch is 1 3/4 in long, what is the area of the whole quilt?
To calculate the area of Spencer's 7x7 quilt, each square patch measuring 1 3/4 inches is calculated for area (3.0625 sq. in.) and then multiplied by the total number of patches (49), resulting in a total quilt area of 150.0625 square inches.
Explanation:Spencer made a quilt for his cousin's doll with a 7x7 array of square patches. To find the area of the whole quilt, we need to calculate the area of one patch and then multiply by the total number of patches. The length of each patch is 1 3/4 inches, which can also be represented as 1.75 inches.
First, we find the area of one patch:
Area of one patch = side length × side lengthArea of one patch = 1.75 inches × 1.75 inchesArea of one patch = 3.0625 square inchesSince there are 49 patches in total (7 patches per row × 7 rows), we then find the total area:
Total area = area of one patch × total number of patchesTotal area = 3.0625 square inches × 49Total area = 150.0625 square inchesTherefore, the area of Spencer's quilt is 150.0625 square inches.
Final answer:
The area of Spencer's quilt is 150.0625 square inches.
Explanation:
Spencer made a quilt for his cousin's doll that had a 7x7 array of square patches, each measuring 1 3/4 inches in length. To find the area of the quilt, you would calculate the area of one patch and then multiply it by the total number of patches in the quilt.
First, convert the inches to a decimal to make the calculation easier:
1 3/4 inches = 1.75 inchesArea of one square patch = length × width
Since the patches are square, the length and width are the same:
Area of one patch = 1.75 inches × 1.75 inches = 3.0625 square inches
To find the total area of the quilt:
Total area of quilt = area of one patch × number of patches
There are 7 rows and 7 columns in the quilt:
Total patches = 7 × 7 = 49
Total area of quilt = 3.0625 square inches × 49 = 150.0625 square inches
Therefore, the area of the whole quilt is 150.0625 square inches.

Plz help! Question in picture. What is the slope?
Answer:
7
Step-by-step explanation:
To find the slop, use (rise/run)
The y goes from 0 to 7/3
The x goes from 0 to 1/3
This means it would be (7/3)/(1/3)
This equals 7 as when you divide fractions, the second fraction goes to its reciprocal and you multiply
7/3 * 3/1
You can eliminate both 3 leaving you with 7/1 which is 7
A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet.
What is the height of the tank if its radius is 16 feet?
Use pi = 3. 14 and round to the nearest foot.
Answer: The height of the tank is 9.02 feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder = π radius² x height
Replacing with values given:
7252 = 3.14 ( 16 )² h
Solving for h (height)
7252 / 3.14(16)² =h
7252 /3.14 (256) =h
7252 / 803.84 = h
9.02 =h
The height of the tank is 9.02 feet
