Answer:

[tex] y = 2x-19 [/tex]

Step-by-step explanation:

Line passes through the point [tex] (12,\: 5) =(x_1,\: y_1) [/tex] and has a slope (m) = 2

Equation of line in point slope form is given as:

[tex] y - y_1 = m(x-x_1) [/tex]

[tex]\therefore y - 5 = 2(x-12) [/tex]

[tex]\therefore y = 2x-24+5 [/tex]

[tex]\therefore y = 2x-19 [/tex]

Answer:

-12 = p

Step-by-step explanation:

Isolate the p terms on one side and the constants on the other side.  Subtract 5p from both sides:  10 = p + 22.  Next, subtract 22 from both sides, obtaining

-12 = p

Answer:

p+12

Answer:

  9600

Step-by-step explanation:

392 years is enough time for 392/98 = 4 doublings of the population. If the population doubles 4 times, it will be 2^4 = 16 times its present value

  16 · 600 people = 9600 people . . . in 392 years

Answer:

No.

Step-by-step explanation:

If it is a regular polygon then the sum of its exterior angles add up to 360 degrees. The number of sides in such a polygon  = 360 / exterior angle.

Here each exterior angle = 180-169 = 11 degrees,

Now 11 is not a factor of 360 and if we try to find the number of sides we don't get a whole number, so the answer is NO.

An interior angle 169° cannot form an regular polygon.

The polygons are the closed shape that has sides and vertices. A regular polygon has all its interior angles equal to each other.  An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon.

For the given situation,

An interior angle of the polygon = 169

The angle of the sum of all the types of interior angles is always equal to 180 degrees.

⇒ [tex]180-169=11[/tex]

Number of sides can be found by dividing the angle by 360°.

We cannot divide 360 by 11, because 11 is not the factor of 360.

Hence we can conclude that an interior angle 169° cannot form an regular polygon.

Answer:

(0, -5)

Step-by-step explanation:

The y-intercept of a graph is where the graph of the function intersects the y-axis. This means that the x-coordinate of the point is zero. To find the y-intercept of a line, when given the equation of the line, substitute (0) in for (x) and solve the equation,

y = x - 5

x = 0

y = 0 - 5

y = -5

This gives the resulting point of (0, -5) for the y-intercept of the line.

Answer:

1260

Step-by-step explanation:

12/72 is 1/6 of the students going to the play

210 students go to play

210 times 6 is 1260

Answer:

1260 students

Step-by-step explanation:

Let x be the number of students in the school.

12 of the 72 students surveyed said they would attend the school pay so  

 (12/72)x=(1/6)x gives the predicted number of ticket sales.  (Here  12*6=72 so it becomes 1/6)

The table shows 210 students purchased tickets so( 1/6)x=210  

x=6*210

x=1260 students attend the school.

Answer:

1. $21

2. $56

Step-by-step explanation:

1.

100% - 30% = 70%

70% * $30 = 0.7 * $30 = $21

2.

100% - 20% = 80%

80% * $70 = 0.8 * $70 = $56

Step-by-step explanation:

The equation for percentages is (percent over 100) times (x over total)  

So for the table the equation is 30/100 * x/30

You cross multiply your total x percent and divide by 100.

So 30 * 30 = 900

900 / 100 = 9

30% of 30 is 9.

Now subtract your answer from the original total (30 - 9 = 21)

So the sale price of the tennis table is $21.

Now repeat for your other equation

Your equation is 20/100 * x/70

So 20 * 70 = 1400

1400 / 100 = 14

20% of 70 is 14.

Now subtract your answer from the original total (70 - 14 = 56)

So the sale price of the easel is $56.

Answer:

slope = [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (2, 4) ← 2 points on the line

m = [tex]\frac{4-0}{2-(-3)}[/tex] = [tex]\frac{4}{5}[/tex]

Answer:

so the answer is 95°

Step-by-step explanation:

The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.

Answer:

Step-by-step explanation:

Solution by completing the square for:

x2−12x+9=0

Keep x terms on the left and move

the constant to the right side

by subtracting it on both sides

x2−12x=−9

Take half of the x term and square it

[−12⋅1/2]^2=36

then add the result to both sides

x^2−12x+36=−9+36

Rewrite the perfect square on the left

(x−6)^2=−9+36

and combine terms on the right

(x−6)^2=27

Take the square root of both sides

x−6=±27−−√

Simplify the Radical term (1):

x−6=±3–√3

Isolate the x on the left side and

solve for x (1)

x=6±3–√3

therefore (2)

x=6+3–√3

x=6−3–√3

which becomes

x=11.1962

x=0.803848

The resulting three-dimensional object is a cone.

We have given that,

A triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1) is rotated about the line x = 1.

We have to determine what will be the resulting three-dimensional object.

A cone is a three-dimensional solid geometric shape having a circular base and a pointed edge at the top called the top.

A cone has one face and a vertex.

Therefore the first option is correct.

Answer:

If we want the greatest portion of pie, then you must choose the section with the greatest angle. Therefore, we must choose Section 2. But if we want the smallest portion of pie, then we must choose Section 1.

Step-by-step explanation:

From statement, we know that measure of the angle ABC is equal to the sum of measures of angles ABD (section 1) and DBC (section 2), that is to say:

[tex]m \angle ABC = m\angle ABD + m\angle DBC[/tex] (1)

If we know that [tex]m\angle ABC = 40^{\circ}[/tex], [tex]m\angle ABD = 2\cdot x + 3[/tex] and [tex]m\angle DBC = 4\cdot x + 7[/tex], then the value of [tex]x[/tex] is:

[tex](2\cdot x + 3)+(4\cdot x + 7) = 40^{\circ}[/tex]

[tex]6\cdot x +10^{\circ} = 40^{\circ}[/tex]

[tex]6\cdot x = 30^{\circ}[/tex]

[tex]x = 5[/tex]

Then, we check the angles of each section:

Section 1

[tex]m\angle ABD = 2\cdot x + 3[/tex]

[tex]m\angle ABD = 13^{\circ}[/tex]

Section 2

[tex]m\angle DBC = 4\cdot x + 7[/tex]

[tex]m\angle DBC = 27^{\circ}[/tex]

If we want the greatest portion of pie, then you must choose the section with the greatest angle. Therefore, we must choose Section 2. But if we want the smallest portion of pie, then we must choose Section 1.

Formula

Area = (central angle divided by 360 ) * pi r^2

Solution

Area = (40 /360) * 3.14 * 6^2
