Answer:

(0,7)

Step-by-step explanation:

This equation you are given is in slope-intercept form, the form y=mx+b.

It is called slope-intercept from because it gives us the slope and the y-intercept.

The slope is m.

The y-intercept is b.

If we compare y=8x+7 to y=mx+b, we should make the conclusion that m=8 and b=7.

This tells the slope is 8 while the y-intercept is 7.

The y-intercept is 7 is sometimes required to be represented by a point.  Since it is the y-intercept, the x is 0 so the point that represents the y-intercept is (0,7).

Answer:

Jane drank 1 3/4 quarts of water.

Jane drank more water than Tom

Step-by-step explanation:

Tom drank  = 1 1/4 quarts of water

Jane drank = 1.75 quarts of water

We have to write the amount of water Jane drank in fraction.

There are some steps to convert decimal into fraction.

Step 1:

Value is 1.75:

Put the 1 aside and just work on 0.75

Write down the decimal value divided by 1

Like, 0.75/1

Step 2:

Now multiply both the numerator and denominator by 100.

We will multiply the numerator and denominator by 100 because 1.75 has two values after the decimal.

0.75 *100/1*100

75/100

Step 3:

Simplify the fraction.

divide the fraction by 5.

=15/20

=3/4

Now bring back the 1: and the fraction will become.

1 3/4

Jane drank 1 3/4 quarts of water.

Now who drank more water?

Jane drank more water than Tom

Reason:

Tom drank 1 1/4 = 5/4

Jane drank  1 3/4 = 7/4

Both the fractions have same denominator, so the value with the greater numerator drank more water than the other.

Therefore Jane drank more water than Tom....

Answer:

[tex]y=\frac{1}{2}x+\frac{5}{2}[/tex]

Step-by-step explanation:

We are going to find the slope by lining up the points vertically and subtract, then put 2nd difference over first.

Also you could just use [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].  It is the same thing.

(  5  ,   5)

-(  1  ,   3)

--------------

  4      2

So the slope is 2/4 or 1/2 after reducing.

The point-slope form a line is

[tex]y-y_1=m(x-x_1)[/tex] with a point on the line [tex](x_1,y_1)=(1,3)[/tex] given and with slope [tex]m=\frac{1}{2}[/tex] given.

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

We are going to solve this for y and simplify what we can because our goal is y=mx+b; this is slope-intercept form.  It is called that because it tells us the slope,m, and the y-intercept,b.

Distribute:

[tex]y-3=\frac{1}{2}x-\frac{1}{2}[/tex]

Add 3 on both sides:

[tex]y=\frac{1}{2}x-\frac{1}{2}+3[/tex]

Simplify:

[tex]y=\frac{1}{2}x+\frac{5}{2}[/tex]

For this case we must find the roots of the following equation:

[tex]3x ^ 2-4x + 2 = 0[/tex]

We have that the roots will come from:

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]

Where:

[tex]a = 3\\b = -4\\c = 2[/tex]

Substituting the values:

[tex]x = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (3) (2)}} {2 (3)}\\x = \frac {4 \pm \sqrt {16-24}} {6}\\x = \frac {4 \pm \sqrt {-8}} {6}\\x = \frac {4 \pm \sqrt {-1 * 8}} {6}\\x = \frac {4 \pmi \sqrt {2 ^ 2 * 2}} {6}\\x = \frac {4 \pm2i \sqrt {2}} {6}\\x = \frac {2 \pmi \sqrt {2}} {3}[/tex]

We have two complex roots:

[tex]x_ {1} = \frac {2 + i \sqrt {2}} {3}\\x_ {2} = \frac {2-i \sqrt {2}} {3}[/tex]

Answer:

[tex]x_ {1} = \frac {2 + i \sqrt {2}} {3}\\x_ {2} = \frac {2-i \sqrt {2}} {3}[/tex]

Answer:

r<280

Step by step explanation:

Subtract 28 from both sides of the equation r+28<308.

r+28 subtracted by 28 leaves us with r<.

308-28 is 280.

Hence the equation becomes r<280.

The expression or inequality is 28 > r < 308 which represents 28 greater than r is less than 308.

It is defined as the combination of constants and variables with mathematical operators.

The question is incomplete.

The complete question is:

Write the expression for the word expression "28 greater than r is less than 308"

It is given that:

The statement is:

28 greater than r is less than 308:

Here r is the real number.

Inequality can be defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

28 > r < 308

Thus, the expression or inequality is 28 > r < 308 which represents 28 greater than r is less than 308.

Answer:

Your slope of the line is -3/10.

Step-by-step explanation:

Use the following equation:

m (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-2 , 7)

(x₂ , y₂) = (18 , 1)

Plug in the corresponding numbers to the corresponding variables:

m = (1 - 7)/(18 - (-2))

Simplify. First solve the parenthesis, then divide:

m = (-6)/(18 + 2)

m = -6/20

Simplify.

m = (-6/20)/(2/2) = -3/10

Your slope of the line is -3/10.

Step-by-step explanation:

Slope formula:

[tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\displaystyle\frac{1-7}{18-(-2)}= \frac{-6}{20}=\frac{-6\div2}{20\div2}=\frac{-3}{10}=-\frac{3}{10}[/tex]

Therefore, the slope is -3/10, and the correct answer is -3/10.

In Mathematics, quadratic functions such as y=ax^2 and cubic functions such as y=ax^3, will have their vertex at the origin, represented by (0,0). These functions show this characteristic because there are no shifts involved in the equation.

In Mathematics, there are different functions that can have their vertex at the origin (0,0). For instance, when we speak of quadratic functions, a function in the form of y = ax^2 will have its vertex at the origin as it's a parabola that opens upward or downward.

Similarly, for the case of cubic functions, a function in the form of y = ax^3 will have the vertex at the origin.

Important to note is that, for all these cases, the vertex is at the origin because there are no horizontal or vertical shifts involved in the equation. That is, the h & k in (x-h)^2+k and (x-h)^3+k are both zero.

Answer:

[tex]574.62\ in^3[/tex]

Step-by-step explanation:

First we calculate the volume of the cylinder.

[tex]V=\pi r^2*l[/tex]

Where r is the radius and l is the length of the cylinder.

We know that:

[tex]r = \frac{diameter}{2}[/tex]

[tex]r = \frac{4}{2}[/tex]

[tex]r = 2\ in[/tex]

Then:

[tex]V=3.14* 2^2*48[/tex]

[tex]V=602.88\ in^3[/tex]

Assuming that the cannon balls are spherical then the volume of the 2 spheres is:

[tex]V=2*\frac{4}{3}\pi r^3[/tex]

[tex]V=2*\frac{4}{3}(3.14)(\frac{3}{2})^3[/tex]

[tex]V=2*\frac{4}{3}(3.14)(\frac{3}{2})^3[/tex]

[tex]V=28.26\ in^3[/tex]

So the space left inside the cannon is

[tex]V=602.88\ in^3 - 28.26\ in^3\\\\V=574.62\ in^3[/tex]

Answer:

m∠C = 55°

Step-by-step explanation:

A triangle's sum of all angles = 180°

Set the equation: m∠A + m∠B + m∠C = 180°

m∠A = 50° ; m∠B = 75°

Plug in the corresponding numbers to the corresponding variables:

50 + 75 + m∠C = 180

Simplify. Combine like terms:

(50 + 75) + m∠C = 180

125 + m∠C = 180

Isolate the variable. Note the equal sign, what you do to one side, you do to the other. Subtract 125 from both sides:

m∠C + 125 (-125) = 180 (-125)

m∠C = 180 - 125

m∠C = 55

m∠C = 55°

Check: All the angles added together must equal 180°:

50 + 75 + 55 = 180

125 + 55 = 180

180 = 180 (True)

Answer:

2[tex]w^{3}[/tex]-6[tex]w^{2}[/tex]+4w=240

Step-by-step explanation:

The length and height are given in terms of the width. Width =w; Length =(2w−4); Height =(w−1); and the Volume is equal to the product of the three. Therefore, we can set up the equation as follows:

w×(2w−4)×(w−1)=240

To finish, we distribute and combine like terms:

(2[tex]w^{2}[/tex]−4w)×(w−1)=240

2[tex]w^{3}[/tex]−2[tex]w^{2}[/tex]−4[tex]w^{2}[/tex]+4w=240

2[tex]w^{2}[/tex]−6[tex]w^{2}[/tex]+4w=240

Therefore, 2[tex]w^{3}[/tex]−6[tex]w^{2}[/tex]+4w=240 is our equation for the dimensions of the dumpster in terms of w.

To find the dimensions of the dumpster given its volume and relationships between dimensions, we express the length and height in terms of the width and substitute these into the volume equation to get 240 = (2W - 4)(W)(W - 1).

The student has been given a problem involving the volume of a rectangular prism, representative of a dumpster, which mathematically belongs to the subject of geometry. The volume is given as 240 cubic feet, and the relationships between the dimensions (length, width, and height) are provided. The length L is described as 4 feet less than twice the width W, and the height H is 1 foot less than the width (W). We can express this information in terms of equations:

L = 2W - 4

H = W - 1

The volume V of a rectangular prism is found using the formula V = LWH. Substituting the given expressions in terms of W into the volume equation, we get:

V = (2W - 4)(W)(W - 1)

Since the volume is given as 240 cubic feet, we can write the equation as:

240 = (2W - 4)(W)(W - 1)

This is the equation in terms of the width W that could be used to find the dimensions of the dumpster.

Step-by-step explanation:

To prove that two sides are parallel on a graph, we must show that their slopes are the same. Plotting this on Desmos, we get the first image attached.  Finding the slopes of each line, we get

[tex]TOP\\\frac{5-3}{6-1} =2/5\\BOTTOM\\\frac{-1-(-1)}{7-2} =2/5\\RIGHT\\-4\\LEFT\\-4[/tex]

As the top slope is the same as the bottom, and the right is the same as the left, this is a parallelogram.

To prove that two sides are congruent, we must find their lengths. The distance formula is

[tex]\sqrt(x_{1}+x_{2})^2+(y_{1}+y_{2})^2 } \\[/tex]

Finding the distances, we get

TOP: [tex]\sqrt{29}[/tex]

BOTTOM: [tex]\sqrt{29}[/tex]

RIGHT:[tex]\sqrt{17}[/tex]

LEFT:[tex]\sqrt{17}[/tex]

As the lengths are the same, the sides are congruent

Answer:x^2+2x+3

Step-by-step explanation:

I’m assuming you meant 2x^4+4x^3+6x^2...

So you can pull out 2x^2 from all of the polynomials...

And this equation isn’t able to be simplified anymore. Hope this helps!

The polynomial 2x^4 + 4x^3 + 6x^2 is factored by first finding the GCF 2x^2, resulting in 2x^2(x^2 + 2x + 3). The quadratic inside the parentheses cannot be factored further with real coefficients.

To factor the polynomial 2x^4 + 4x^3 + 6x^2, we first look for the greatest common factor (GCF) that can be factored out. In this case, each term has at least a factor of 2 and an x^2. Factoring out the GCF, we get:

2x^2(x^2 + 2x + 3)

Now, we look at the quadratic inside the parentheses to see if it can be factored further. However, the quadratic x^2 + 2x + 3 does not factor neatly over the integers because the discriminant, b^2 - 4ac, is negative (2^2 - 4(1)(3) = 4 - 12 = -8). Since we are only looking for real coefficients and not complex ones, we conclude that the quadratic cannot be factored further, and so the polynomial is fully factored as 2x^2(x^2 + 2x + 3).
