The answer I believe it’s A if not try C

The correct answer is c) C(4) = 398, which appropriately links the cost of manufacturing 4 pairs of sunglasses ($398) with the function C(x).

The function C(x) represents the cost to manufacture x pairs of sunglasses.

Given that it costs $398 to manufacture 4 pairs, we can substitute these values into the function to find which statement is accurate.

The logic behind this is simple: C(x) is typically understood to be the cost associated with producing x units.

Therefore, when x is the number of units produced, C(x) is the total cost to produce those units.

Substituting 4 into the function C(x) would give us the total cost for 4 pairs of sunglasses.

Thus, we can say C(4) = 398. This matches response option c), which states that C(4) = 398, and is therefore true.

Response options a), b), and d) all incorrectly mix up the inputs and outputs of the cost function and therefore can be disregarded.

Answer:

(3, 2)

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

3x + y = 11 → (2)

Substitute y = 2x - 4 into (2)

3x + 2x - 4 = 11

5x - 4 = 11 ( add 4 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Substitute x = 3 into (1) for corresponding value of y

y = (2 × 3) - 4 = 6 - 4 = 2

Solution is (3, 2)

Answer:

Step-by-step explanation:

this system not equation :

y=2x-4 ....(1)

3x+y=11​....(2)

put the value of y by (1)  in to (2) :

3x+2x-4 = 11

add4 : 3x+2x =15

5x=15

x=15/5 = 3

but: y = 2x-4

so :  y =  2(3) -4

y = 6-4=2

Answer:

1 fifteenth, or 1/15

Step-by-step explanation:

If there are 3 sons multiply the fraction by 3 and then you have 12/15 because 12/15 is equal to 4/5, so the remaining is 3 out of 15, so divide that between the 3 sons and boom, 1/15th per son.

Answer:

y= 1.67

Step-by-step explanation:

0.6y + 1.2 = 0.3y + 0.9 + 0.8y

0.3 = 0.5y

1.67 = y

Answer:

0.6y+1.2=0.3y-0.9+0.8y

       +0.9=        +0.9

0.6y+2.1=1.1y

-0.6y=-0.6y

2.1=0.5

y=4.2

Step-by-step explanation:

First you want to isolate the variable to one side which is exactly why I added 0.9 to both sides. Then you want to combine like terms. By combining like terms you can now distribute the variable by the value remaining, which led to me getting y=4.2

Answer:

25.

Step-by-step explanation:

Use the identity cos 2x = 2 cos^2 x - 1

So cos 50 = 2 cos^2 25 - 1

So the space  = 25.

Answer:

25°

Step-by-step explanation:

Using the double angle trigonometric identity for cosine

• cos2x = 2cos²x - 1

Here 2x = 50° ⇒ x = 25°, thus

cos50° = 2cos²25° - 1

Final answer:

The period of a sinusoidal function is the amount of time it takes for the function to complete one full cycle.

Explanation:

The period of a sinusoidal function is the amount of time it takes for the function to complete one full cycle. In this case, if the period of the sinusoidal function is 18, then the function will complete one full cycle every 18 units of time. This means that after 18 units of time, the function will have returned to its starting point.

For example, if we have a sinusoidal function f(x) = sin(x), then the period of this function is 2π, because it takes 2π units of time for the function to complete one full cycle. In general, the period of a sinusoidal function can be calculated using the formula T = 2π/ω, where T is the period and ω is the angular frequency.

The given range is comprised of cards with a value between 3 and 7, inclusive, and there are 4 of each from the available suits. So there are 20 cards that fit the bill.

The probability of drawing 1 such card is

[tex]\dfrac{\binom{20}1}{\binom{52}1}=\dfrac{20}{52}=\dfrac5{13}[/tex]

In a standard 52 card deck, there are 20 cards that are greater than 2 and less than 8. As such, the probability of being dealt one of these cards is 20/52, which is approximately 0.385 or 38.5%.

In a standard deck of 52 cards, there are four suits: hearts, diamonds, clubs, and spades. Each suit contains 13 cards: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, and King.

Answer:

14.75 :) please give me brainliest :)

Step-by-step explanation:

Hello There!

Mean: Average of numbers in a set of data.

STEP 1: Add the numbers up. In this case, we would add

12 + 17 + 16 + 10 + 20 + 13 + 14 + 14 + 12 + 12 + 19 + 18 = 177

STEP 2: Divide the sum of the number by the number of digits you added.

We would divide 177 "sum of numbers" by 12 "number of digits" and would

get a quotient of 14.75

The mean for this set of data is 14.75

For this case we have that the point-slope equation of a line is given by:

[tex]y-y_ {0} = m (x-x_ {0})[/tex]

Answer:

He can make 9 Muffins

Step-by-step explanation:

16*2.25=36

51.75 - 36=15.75  Subtract the total number of selling he made by how much he made with the brownies

15.75/1.75=9 Divide the number you got after subtracting by by how many he  is going to sell each of then

Omar made $36 from selling brownies. He made $15.75 from selling muffins, and since each muffin cost $1.75, he therefore sold 9 muffins at the bake sale.

To solve this problem, we must first find the total money Omar made from selling brownies. We do this by multiplying the price of each brownie ($2.25) by the number of brownies sold (16), which gives $36. Then we subtract this total from the total money Omar made ($51.75) to find out how much money he made from selling muffins, which is $51.75 - $36 = $15.75.

Next, we divide this amount by the price of each muffin ($1.75) to find out the number of muffins sold, as follows: $15.75 ÷ $1.75 = 9.

So, Omar sold 9 muffins at the bake sale.

Answer: the answer is 2

Step-by-step explanation:

12 x 2 is 24

12 x 3 is 36

so it goes into 32, 2 times.

Final answer:

12 goes into 32 a total of 2 full times with a remainder of 8, which can also be expressed as 2 and 2/3 times. The calculation is done using long division.

Explanation:

The question asks how many times does 12 go into 32. This is a division problem where you need to divide 32 by 12. To calculate this, you can use long division. Dividing 32 by 12 gives you 2 with a remainder of 8, since 12 times 2 is 24 and 32 minus 24 leaves 8. Therefore, 12 goes into 32 2 full times with 8 left over, or 2 remainder 8.

Another way to express this is in terms of decimal or fractions. Since 8 is 2/3 of 12, you can also say that 12 goes into 32 2 and 2/3 times. However, if you are strictly looking for how many full times 12 can divide into 32 without considering fractions, the answer is simply 2.

Area: 4069.44

Circumference: 226.08

Step-by-step explanation:

The equation for the area of a circle is:

pi(r^2)

So they told us to use 3.14 for pi, the r (radius)is found by dividing the diameter (72) by 2 since

r = d/2

r = 72/2 = 36

plug this into the equation for the area of a circle:

3.14(36^2) = 4069.44

——————————————————————————————————

To find the circumference, use the equation for it:

2 x pi x r or pi x d

Let’s use the second equation, since the diameter is already given

2(3.14)(72) = 226.08

Answer:

Area is 4069.44 m². Circumference is 226.08 m.

Step-by-step explanation:

Area:

The Pythagorean theorem is used in a similar manner to compute the diagonal of a rectangle and a rectangular prism. In both cases, the theorem is utilized to find the length of a line connecting two opposite corners across the shape or space.

In the field of Mathematics, the Pythagorean theorem presents a fundamental relationship within a right triangle which expresses that the square of the hypotenuse (the side opposite the right angle) is equivalent to the sum of the squares of the other two sides. This theorem is represented mathematically as a² + b² = c².

When applying this theorem in a rectangle, consider a diagonal drawn from one corner to the opposite corner, which gives us a right triangle. To find the length of this diagonal (hypotenuse), we use the Pythagorean theorem, considering the two sides of the rectangle as the other two sides of the triangle.

In a rectangular prism, the same principle applies. However, instead of two sides (as in a rectangle), we now have three dimensions (length, width, and height) to consider. When one wishes to find the distance from one corner to the opposite corner (a diagonal cutting through the prism), the Pythagorean theorem can be employed. First, a right triangle is considered in the base of the prism, and the Pythagorean theorem is used to find the length of the diagonal of the base. Next, a second right triangle is constructed using the height of the prism and the diagonal of the base. Once again, the Pythagorean theorem can be implemented to calculate the length of the longest diagonal of the prism.

#SPJ12

The Pythagorean theorem applies similarly in both rectangular prisms and rectangles, using right triangles to calculate distances.

The Pythagorean theorem is fundamentally the same in both a rectangular prism and a rectangle, as it relies on the properties of right triangles. For a rectangle, the theorem states that the sum of the squares of the two shorter sides (a and b) equals the square of the hypotenuse (c), or a² + b² = c².

When applied to a rectangular prism, the theorem is used in three dimensions to find the length of the diagonal (d) stretching between opposite corners. In a rectangular prism, by applying the Pythagorean theorem successively across two-dimensional planes, we first calculate the diagonal of one face of the prism (b² = x² + y²).

Then, we incorporate the third dimension z to find the space diagonal: d² = x² + y² + z². This sequential application of the Pythagorean theorem leverages its two-dimensional principle to solve for three-dimensional distances.

Steps to Apply Pythagorean Theorem in a Rectangular Prism:

This demonstrates how the Pythagorean theorem's consistent application in both two and three dimensions allows calculation of diagonals and distances in various geometric contexts.
