Answer:

$2.10x + 5= $49.10

x=21

Step-by-step explanation:

the x is used for a variable that changes and in this case the mph changes which lead x being the amount of miles that they had drove which at the end ends up multi. with the $2.10 . as for the 5 it was an initial as in it doesn't change.

for the second part

you subtract 5 from each side so you have the total of 2.10x= 44.10 then u divide 2.10 from each side and that will give you x = 21

Answer: 1.45 million is your answer

Step-by-step explanation:

The number of accessories produced that yields approximately the same profit as 2 million is 3.45 million. The correct option is B.

Revenue is defined as the money generated by normal business operations and is calculated by multiplying the average sales price by the number of items sold.

The profit (P) made by the company can be calculated as follows:

P = (Revenue) - (Costs)

Where Revenue = (Price per accessory) × (Number of accessories produced), and Costs = (Cost per accessory) × (Number of accessories produced).

So, using the given information, we can write:

P = (100-10x^2) x - (10x)

where x is the number of accessories produced in millions.

We know that the company makes a profit of 100 million dollars when it produces 2 million accessories, so we can set P = 100 and x = 2, and solve for the constant of proportionality k:

100 = (100-10(2)^2)(2) - (10)(2) + k

k = 200

Now, we can set P ≈ 100 again and solve for x, using k = 200:

100 = (100-10x^2)x - (10x) + 200

0 = -10x^3 + 10x^2 + 10x + 100

0 = -x^3 + x^2 + x + 10

We can solve this equation using synthetic division or by using a graphing calculator, and we find that there is a root between x = 3 and x = 4.

Therefore, the number of accessories produced that yields approximately the same profit as 2 million is 3.45 million, which is option B.

The solution set for the given expression is {0,  π/2,  π}.

Here we have the expression:

[tex]tan(\frac{3\pi}{4} -2x) = -1[/tex]

First, we know that:

[tex]tan(\frac{3\pi}{4}) = -1[/tex]

So, if x = 0, the equation is true, which means that x = 0 is a solution.

And the tangent function as a period of pi.

This means that:

tan(x) = tan(x -  π) = tan(x - 2*π) etc.

Then if x = π/2 and x = π also are solutions, so we conclude that the solution set is:

{0,  π/2,  π}

Step-by-step explanation:

Linear equation systems can consist of two or three equations with two or three unknowns respectively.

A system of linear equations in two variables has infinite solutions when the lines made by them overlap each other and similarly a system with three variables has infinite solutions when two lines overlap each other and third plane is parallel to them

Hence,

Step-by-step explanation:

Answer:

Ok, so this tire is 2 feet which is represented by 3 inches.

So, since the tire has a diameter of 33 inches, we multiply 33 by 3

33 times 3 is 99.

Answer:

use the distance formula you can find it on the net

The distance between (-6,8) and (10,-4) is 20 units.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]

We are given that;

The points (-6,8) and (10,-4)

Now,

To use the formula, you need to plug in the values of x1, y1, x2 and y2 into the formula and simplify. For example, to find the distance between (-6,8) and (10,-4), you can do:

d = (10 - (-6))^2 + (-4 - 8)^2

d = (16)^2 + (-12)^2

d = 256 + 144

d = 400

d = sqrt(400)

d = 20

Therefore, the distance formula the answer will be 20 units.

The equation of a line is given by:

y = mx + c

Where m is the slope.

Slope = (d - b) / (c - a)

Where (a, b) and (c, d) are the two points.

The slope of the linear function is 3.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example: y = -3x - 4

Slope = -3 and y-intercept is -4.

We have,

A table that represents a linear function.

x  y

2  7

5  16

7  22

9  28

We can have points such as:

(x, y) = (2, 7), (5, 16), (7, 22), and (9, 28)

We can select any two points and find the slope.

(2, 7) = (a, b)

(5, 16) = (c, d)

Slope:

= (d - b) / (c - a)

= 16 - 7 / 5 - 2

= 9 / 3

= 3

Slope = 3

Thus,

The slope of the linear function is 3.

1.3°F * 10 = 13°F

10.2°F

Step-by-step explanation:

Given that:

Temperature on the ground = - 2.8°F

Change in temperature per 1000 ft rise = 1.3°F

Change in temperature after the plane ascends 10000 ft

Change in temperature per 1000ft rise * (10000/1000)

1.3°F * 10 = 13°F

B.) Temperature at 10,000 feets

Temperature on ground + change in temperature at 10,000ft

-2.8°F + 13°F

= 10.2°F
