The cost of producing hard drives has three parts: cost of materials, cost of labor, and cost of equipment. To produce x hard drives, the cost of materials is 30x dollars and the cost of labor is 10x cents. The cost of equipment is a one-time, fixed amount of $10,000. Which equation could represent the cost function for making x hard drives? Answer Choices f(x)=10,030.1x f(x)=10,000x+40 f(x)=30.1x+10,000 f(x)=40x−10,000

Answers

Answer 1

Let [tex]x[/tex] represent the number of hard drives produced.
The first thing we need to do is convert 10 cents to dollars:
[tex]10cents( \frac{1dollar}{100cents} )=0.1dollar[/tex]. Now, we know that the the cost of materials is 30 dollars and the cost of labor is 0.1 dollars, so the total coast to produce [tex]x[/tex] hard drives will be: [tex]30+0.1=30.1x[/tex].
Now the only thing left is add the cost of equipment to complete our function:
[tex]f(x)=30.1x+10000[/tex]

We can conclude that the equation that could represent the cost function for making x hard drives is f(x)=30.1x+10,000

[tex]\bf 4x^3+2x^2+2x\implies 2x(2x^2+x+1)[/tex]

so in short, the only factoring doable to it, without any complex factors, is that of taking the common factor of 2x.

now, the trinomial of 2x²+x+1, will not give us any "real roots", just complex or "imaginary" ones.

if you have already covered the quadratic formula, you could test with that, or you can also check that trinomial's discriminant, and notice that it will give you a negative value.

Answer:

[tex]2x(2x^2+x+1)[/tex]

Step-by-step explanation:

We have been given an expression and we are asked to find factor out our given expression.

[tex]4x^3+2x^2+2x[/tex]

To factor our given expression we need to factor out the greatest common factor of each term of our given expression.

When a number is divided by -3, the result is 12 more than the number what is the number?

Answers

Final answer:

To find the number that, when divided by -3, the result is 12 more than the number, we set up an equation and solve it to get the answer, which is -9.

Explanation:

When a number is divided by -3, and the result is 12 more than the number itself, we can set up the following equation to find the number: number / -3 = number + 12. Following division and multiplication rules for signs, and executing proper algebraic manipulations, we can solve this equation.

First, we multiply both sides by -3 to get rid of the fraction:
-3 * (number / -3) = -3 * (number + 12),
which simplifies to:
number = -3(number) - 36.
Next, we add 3(number) to both sides to get:
4(number) = -36.
Finally, we divide both sides by 4 to isolate the 'number':
number = -36 / 4
number = -9.

Therefore, the number in question is -9.

Answers

The area of a blade with rectangular shape = 1/2 * b * h where b is the base and h, the height. Here b = 7 and height = 4 So the area of the blade = 1/2 * 7 * 4 = 14ft^2 If the are four blades the total area is the summation of individual blade. So area = 14 + 14 + 14 + 14 = 56ft^2.

To find the total area of this figure, it would be easiest to find the area of the left part (rectangle) and then find the area of the right part (triangle), and then add the two area values together.

First, we will find the area of the rectangle, using the formula A = lw, where l is the length of the rectangle and w is the width of the rectangle.
The length of the rectangle is 13 cm and the width is 9 cm. If we substitute in these values into our equation, we get:
A = (13cm)(9cm)
A= 117 cm^2

Next, let’s find the area of the triangle, using the formula A=(1/2)bh, where b is the base of the triangle and h is the height.
The base of the triangle is 11 cm and the height of the triangle is 5 cm (found by subtracting 13-8 as seen in the figure). If we substitute in these values and simplify, we get:
A=1/2(11cm)(5cm)
A=1/2(55cm^2)
A=27.5 cm^2.

When we add together the area of the rectangle with the area of the triangle, we will get the total area of the figure.

117 cm^2 + 27.5 cm^2 = 144.5 cm^2
Your answer is 144.5 cm^2 or the first option.

Suppose that the center of the carousel is at the origin and that one of the animals on the circumference of the carousel has coordinates (24, 32). If one unit of the coordinate plane equals 1 foot, what is the diameter of the carousel

Answers

1. You have that the Standard form for the equation of a circle when its center is at the origin, is:

x²+y²=r²

2. You must calculate the radius. Then:

r=√(x²+y²)

x=24
y=32

3. When you substitute the values of "x" and "y" into the equation r=√(x²+y²), you obtain:

r=√(x²+y²)
r=√(24²+32²)
r=√(576+1024)
r=√1600
r=40 feet

4. Therefore, the diameter (D) of the circle, is:

D=2r
D=2(40 feet)

Write the equation, in slope-intercept form, of the line passing through the origin and the point $(-4,3)$.

Answers

If the equation is passing trough the origin, it will be passing trough the point (0,0). We now for our problem that the equations is also passing trough the point (-4,3). So, our line is passing trough the points (0,0) and (-4,3). To write the equation in slope-intercept form, first, we need to find its slope [tex]m[/tex]. To do that we are going to use the slope formula: [tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}} [/tex].
From our two points we can infer that [tex]x_{1}=0[/tex], [tex]y_{1}=0[/tex], [tex]x_{2}=-4[/tex], [tex]y_{2}=3[/tex]. Lets replace those values in the slope formula:
[tex]m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}} [/tex]
[tex]m= \frac{3-0}{-4-0} [/tex]
[tex]m= \frac{3}{-4} [/tex]
[tex]m=- \frac{3}{4} [/tex]

Now that we have our slope, we can use the slope-intercept formula:
[tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y-0=- \frac{3}{4} (x-0)[/tex]
[tex]y=- \frac{3}{4} x[/tex]

We can conclude that the equation of the line passing trough the points (0,0) and (-4,3) is [tex]y=- \frac{3}{4} x[/tex].

Answers

Based on the picture, we know that ED is equal to DB. Therefore:

2 times ED=EB
2(10)=20

EB is 20

Answer:
EB = 20 units

Explanation:
This question can be solved using two methods:
Method #1:
From the image, we can note that D is the midpoint of EB, therefore, ED = DB
This means that:
EB = 2*10 = 20 units

Method #2:
From the image, we know that ED = DB
We are given that ED = 10 units
Therefore:
DB = 3x - 8 = 10
3x = 18
x = 6
DB = 3(6) - 8 = 18 - 8 = 10 units
EB = EB + DB = 10 + 10 = 20 units

A little help pwease :o ? A group of 45 people attended a ball game. There were twice as many children as adults in the group. Set up a system of equations that represents the numbers of adults and children who attended the game and solve the system to find the number of children who were in the group. O.o

Answers

45= 2(a) + a
45= 2a + a
45= 3a
15= a

30. Since there are twice as many children as adults, let's say the number of adults is x. That means the amount of children is 2x. You know that in total there are 45 people. This means that the number of adults plus the number of children is 45. So we can set up x + 2x = 45. We can solve for x. 3x = 45 so x = 15. Remember, as we stated before, x is the number of adults. 2x is the number of children. Since x = 15, 2x = 30 so there are 30 children in the group.

The difference of two numbers is 44 1/2 . If the smaller of the two numbers increases 7 times then the difference will be 10 3/14 . Find the numbers.

The numbers are: ___ ,___ or ____,___

Answers

Answer: The smaller number is 9 and 5/42. The larger number is 53 and 13/21.

To find these answer you have to write the following two equations.

x - y = 44 and 1/2
7y - x = 10 and 3/14

Then, you can use the substitution method to solve them. Change the first equation to: x = 44 + y. Substitute that into the second equation and solve for y. Once you have that, plug it back into the first equation and solve for x.

The smaller number is 11 and the larger number is [tex]55 \frac{1}{2}[/tex].

Let's denote the two numbers as x and y, where x is the smaller number. We're given that [tex]y - x = 44 \frac{1}{2}[/tex] and [tex]7x - y = 10 \frac{3}{14}[/tex].

To solve this system of equations, we can use substitution or elimination. Let's use elimination:

1. Multiply the second equation by 2 to clear fractions: [tex]14x - 2y = 20 \frac{6}{14}[/tex].

2. Add the modified second equation to the first equation:

[tex](y - x) + (14x - 2y) = 44 \frac{1}{2} + 20 \frac{6}{14}[/tex]

[tex]13x - y = 64 \frac{11}{14}[/tex]

Now, we have a simpler equation: [tex]13x - y = 64 \frac{11}{14}[/tex].

3. Add this equation to the original second equation to find x:

[tex]7x - y + 13x - y = 10 \frac{3}{14} + 64 \frac{11}{14}[/tex]

[tex]20x - 2y = 75[/tex]

4. Now, we can solve this equation along with the first equation to find x and y.

After solving, we get x = 11 and [tex]y = 55 \frac{1}{2}[/tex].

The smaller number is 11 and the larger number is [tex]55 \frac{1}{2}[/tex].

Thus, the numbers are [tex]{11 \text{ and } 55 \frac{1}{2}}[/tex].

The amount of cups of flour needed to make 1/2 of the original recipe is 7/8 cups.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Recipe:

Amount of flour for muffins = [tex]1\frac{1}{2}[/tex] = 3/2 cups

Amount of flour for toppings = [tex]\frac{1}{4}[/tex] = 1/4 cups

The total amount of flour:

= 3/2 + 1/4

= (12 + 2) / 8

= 14 / 8

= 7/4 cups

We see that the total amount of flour needed to make one Cara muffin recipe is 7/4 cup of flour.

To make 1/2 of the original recipe.

The amount of flour needed:

1 recipe = 7/4 cups

Divide both sides by 2.

1/2 recipe = 1/2 x 7/4 cups

1/2 recipe = 7/8 cups

Thus,

The amount of cups of flour needed to make 1/2 of the original recipe is 7/8 cups.
