Answer:

y = 5/2 x

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

    = (5-0)/(2-0)

     = 5/2

We know the y intercept is 0 since it goes through the origin

y = mx+b

y = 5/2 x +0

y = 5/2 x

Answer:

V≈461.81in³ That is the answer!

V = pi*r^2*h

V = pi*(3.5)^2*12

V = pi*12.25*12

V = pi*147

V = 147pi  .... exact volume in terms of pi

V = 461.8141200777 is the approximate volume (use a calculator here)

The units for the volume are in cubic inches

Side note: If you use pi = 3.14, then you'll get an approximate volume of 147*pi = 147*3.14 = 461.58 which is a bit off from the other value we got earlier due to the fact pi = 3.14 is not as accurate as using the calculator's internal value of pi.

Answer:

I keep getting 141.421... so rounded it would be 141.4

Step-by-step explanation:

The length of the interior diagonal of the box is approximately 141.4 cm.

Suppose the base of the prism has length = l units, and width = w units.

Suppose that the height of the prism is of h units, then:

[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]

is the volume of that prism.

The base is a rectangle with length = L units, and width = W units, so its area is:

[tex]b = l \times w\: \rm unit^2[/tex]

We are given that;

Height= 100cm

Width=80cm

Length=60cm

Now,

Using the Pythagorean theorem, we can find the length of the interior diagonal as:

diagonal = sqrt(l^2 + w^2 + h^2)

diagonal = sqrt(100^2 + 80^2 + 60^2)

diagonal = sqrt(10000 + 6400 + 3600)

diagonal = sqrt(20000)

diagonal ≈ 141.4

Therefore, the length of the diagonal of prism will be 141.4

Answer:A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).

Step-by-step explanation:

Answer:

There can be more than one solution to a system of equations. A system of linear equations will have one point of intersection, or one solution. To graph a system of equations that are written in standard form, you must rewrite the equations in slope -intercept form.

Step-by-step explanation:

To find the total views a music video got over the first 5 days with a 20% daily increase, calculate the views for each day using a geometric sequence formula and sum them, resulting in approximately 13023 views.

To calculate the total views a music video got over the course of the first 5 days with a 20% daily increase starting at 1750 views, we use the geometric sequence formula V = V0 × (1 + r)n, where V0 is the initial number of views (1750), r is the daily increase rate (0.20), and n is the day number. The total views (TV) over 5 days is calculated by summing the individual daily views.

Day 1: 1750 views

Day 2: 1750 × (1 + 0.20) = 2100 views

Day 3: 1750 × (1 + 0.20)2 = 2520 views

Day 4: 1750 × (1 + 0.20)3 = 3024 views

Day 5: 1750 × (1 + 0.20)4 = 3628.8 views, rounded to 3629 views

The total views over the five days is the sum of daily views: 1750 + 2100 + 2520 + 3024 + 3629 = 13023 views.

Answer:

1. 21 represents the cost of manufacturing one handband.

3. The initial start up cost is $15000.

5. The company spends $57000 to manufacture 2000 handbands.

Step-by-step explanation:

We are given the cost function for manufacturing 'h' amount of handbands and it is provided that there was initial start up costs involved.

Now, as the cost function is given by, C(h) = 21h + 15000.

We can see that the initial start up cost is $15000.

As, 'h' is the number of handbands being made. So, 21h in C(h) is the cost of manufacturing 'h' handbands.

Therefore, 21 is the cost of manufacturing one handband.

Since, C(h) = 21h + 15000.

Substituting h = 2000, we get,

C(2000) = 21×2000 + 15000.

i.e. C(2000) = 42000 + 15000.

i.e. C(2000) = 57000.

The company spends $57000 to manufacture 2000 handbands.

Since, we are provided with only cost function, we can not talk about the profit.

Hence, option 1, 3 and 5 are correct.

Answer:

D)-5x = -10

Step-by-step explanation:

The equation results from adding the equations in this system is -5x = -10.

Option D is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 7 is an equation.

We have,

-8x + 8y = 8 _____(1)

3x - 8y = -18 _____(2)

Now,

Adding (1) and (2) we get,

-8x + 8y + 3x - 8y = 8 - 18

-5x = -10

Thus,

-5x = -10 is the equation.

Answer:

The volume of the cube is D * D * D or D³ cm³

Step-by-step explanation:

The point-slope equation for the line passing through (-2, -20) and (9, 79), is y = 9x - 2.

To find the point-slope equation for the line that passes through the points (-2, -20) and (9, 79), we first need to calculate the slope (m). The formula for the slope is given by:

m = (Y2 - Y1) / (X2 - X1)

Using the given points, we get:

m = (79 - (-20)) / (9 - (-2)) = 99 / 11 = 9

Now, using the point-slope form of the equation y - y1 = m(x - x1), and the first point (-2, -20), we have:

y - (-20) = 9(x - (-2))

Simplifying this, we get:

y + 20 = 9(x + 2)

Or

y = 9x + 18 - 20

y = 9x - 2

This is the point-slope equation for the line that passes through the points.

use the formula for hypotenouse of a triangle to find the diangles as if they were the hypotenouse so 5 squared plus 10 squared is 25 plus 100 which is 125 which has the square root 11.2. so now you have the length (longer side) so for the width it's 1 squared plus 2 squared which is 1 plus 4 is 5 so the square root of 5 is about 2.2 so that's the width (shorter side) so now for the area it's 11.2 (length) times 2.2 (width) which is about 25. hope this hopes let me know if you have a question

Answer:

The length of the third side could be anywhere between [tex]7\; \rm in[/tex] and [tex]17\; \rm in[/tex], excluding the two endpoints.

Step-by-step explanation:

Let [tex]x[/tex] represent the length (in inches) of the third side.

In a triangle, the sum of the lengths of any two sides should be greater than the length of the third side. The lengths of the three sides of this triangle are:

The sum of the lengths of the first two sides is [tex]5 + 12 = 17\; \rm in[/tex]. This sum should be greater than (not equal to) the length of the third side: [tex]x\; \rm in[/tex]. That gives the first inequality:

Similarly, the sum of the lengths of the first and the third sides is [tex](5 + x)\; \rm in[/tex]. This sum should be greater than (not equal to) the length of the second side: [tex]12\; \rm in[/tex]. That gives the second inequality:

The sum of the lengths of the second and the third sides is [tex](12 + x)\; \rm in[/tex]. This sum should be greater than (not equal to) the length of the first side: [tex]5\; \rm in[/tex]. That gives the third inequality:

Solve the three inequalities for the range of [tex]x[/tex], the length of the third side:

[tex]\displaystyle \left\lbrace\begin{aligned}& 5 + 12 > x \\ & 5 + x > 12 \\ & 12 + x > 5\end{aligned}\right.[/tex].

The first inequality simplifies to [tex]x < 17[/tex]. The second inequalities gives [tex]x > 7[/tex], while the third gives [tex]x > -7[/tex].

Refer to the diagram attached. [tex]7 < x < 17[/tex] is the region that satisfies all three inequalities. Therefore, the length of the third side should be between [tex]7[/tex] and [tex]17[/tex], exclusive.

Final answer:

To solve the system of equations y = 4x and 3x + 2y = 55, you can substitute 4x for y in the second equation, simplify to find x = 5, and then calculate y = 20.

Explanation:

To solve for x and y using the equations y = 4x and 3x + 2y = 55, you can use substitution or elimination. Let's use substitution since we already have y expressed in terms of x.

Substitute 4x for y in the second equation: 3x + 2(4x) = 55.

Simplify and solve for x: 3x + 8x = 55 becomes 11x = 55, so x = 5.

Substitute x back into the first equation to find y: y = 4(5), so y = 20.

Therefore, the solution to the system of equations is x = 5 and y = 20.
