Answers

Answer 1

Answer:

2n³ - 3n² - 7n + 3

Step-by-step explanation:

Given

(n² - 3n + 1)(2n + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) ← distribute the parenthesis

= 2n³ + 3n² - 6n² - 9n + 2n + 3 ← collect like terms

= 2n³ - 3n² - 7n + 3

Given :-

Sides of the polygon = 20

To Find :-

Exterior angle of the polygon

Formula :-

Exterior angle of the polygon = ( 360/ n )°

where,

n = number of sides of the polygon ( 20 sides)

Solution :-

By substituting values according to the formula

➙ ( 360/ 20 )°

➥ 18°

Hence, The exterior angle of the polygon is 18°

Answers

Answer:  x = 37

===================================================

Explanation:

The combination of angle x and the 93 degree angle forms x+93. This obtuse angle is congruent to 130 because these two angles are alternate interior angles and because line L is parallel to line M.

So,

x+93 = 130

x+93-93 = 130-93 .... subtracting 93 from both sides

x = 37

Polygon E’F’G’H’

is a dilation image of the polygon

EFGH

What is the scale factor of the dilation?

A.3

B.6

C.12

D.1/3

Answers

Answer:

The scale factor of the dilation is 3 A

Step-by-step explanation:

If a polygon dilated by a scale factor k, then the ratio between its sides and the corresponding sides of its image equals k The length of a vertical segment is the difference between the y-coordinates of its endpoints

In the given figure

∵ EFGH is a polygon

E = (-2, 1), H = (-2, -1)

∵ EH is a vertical side

→ By using the 2nd rule above

∴ The length of EH = 1 - (-1) = 1 + 1

The length of EH = 2

∵ E'F'G'H' is its image after dilation by scale factor k

E' = (-2, 5), and H' = (-2, -1)

∵ E'H' is a vertical side

∴ The length of E'H' = 5 - (-1) = 5 + 1

The length of E'H' = 6

→ By using the 1st rule above

∴  [tex]\frac{E'H'}{EH}[/tex] =  [tex]\frac{E'F'}{EF}[/tex] =  [tex]\frac{H'G'}{HG}[/tex] =  [tex]\frac{F'G'}{FG}[/tex] = k

∵  [tex]\frac{E'H'}{EH}[/tex] = k

∵ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{6}{2}[/tex]

∴  [tex]\frac{E'H'}{EH}[/tex] = 3

k = 3

The scale factor of the dilation is 3

What is the equation of the line that passes through the points 1/2/3 and (-1,-1

a.y=-6x+5

b.Y=5/6X-1/6

C.Y=2/3X+1/5

D.y=6/5x+1/5

Answers

Answer:

(1, 2/3) (-1, -1) are the points. use the slope formula to find the slope y2-y1/x2-x1

(-1 - 2/3) / (-1 -1) (answer both sides of the division side)

-5/3 / -2  (divide)

slope = 5/6  (the slope)

plug in values you know into point-slope form (y -y1) = m(x-x1)

y - (-1) = 5/6 (x - (-1) (i chose the easier point to plug in. two neg. make a pos. )

y +1 = 5/6 (x +1)  (use the distributive property)

y +1 = 5/6x+5/6  (subtract 1 from both sides)

y = 5/6x - 1/6  or B (this is the equation)

Lake Michigan is one of five great lakes in north america.In summertime, lake Michigan recedes about 1/4 foot per hour. Lake Michigan is about 279 ft. In depth.

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. However, a possible question is "calculate the depth of the lake after certain number of hours (say 2 hours)"

Given

[tex]Rate = \frac{1}{4}ft/hr[/tex]

[tex]Depth = 279ft[/tex]

First, we calculate the depth receded.

If the rate is 1/4ft per hour

Then

The Depth receded in 2 hours is:

[tex]Receded = \frac{1}{4} * 2[/tex]

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

[tex]Receded = 0.5ft[/tex]

The new depth is then calculated as:

[tex]New\ Depth = 279ft - 0.5ft[/tex]

[tex]New\ Depth = 278.5ft[/tex]

Step-by-step explanation:

The Pythagorean theorem tells you ...

  FB^2 = BC^2 +CF^2

  FA^2 = FB^2 +BA^2

Substituting for FB^2, we have ...

  FA^2 = BC^2 +CF^2 +BA^2 = x^2 +x^2 +x^2

  FA^2 = 3x^2

  FA = x√3 = 30 . . . . take the square root and substitute for FA

  x = 30/√3

Step-by-step explanation:

Median: First write in ascending order. If number of data's is odd, median is the middle data.

If number of data's is even, then median = average of n/2th and (n+2)/2th term.

1) 1 , 3 , 5 , 5 , 6

Median = 5

2) 3,4,10,2,1

Ascending order: 1,2,3,4,10

Median = 3

3) 4, 5,7,11

Median = (5+7)/2 = 12/2 = 6

4) 1,1,2,6

Median = (1+2)/2 = 3/2 = 1.5

5) 2,2,3,3,,5,7

Median = 3+3/2 = 6/2 = 3

6)1,2,4,6,7,7

Median = (4+6)/2 = 10/2 = 5

7) 2,2,3,6,7,8

Median = (3+6)/2 = 9/2 = 4.5

8)1,2,3,14,17,18

Median = (3+14)/2 = 17/2 = 8.5

3)Mean = (5+4+6+1)÷4 = 16÷4 = 4

4)Mean = (2+5+1+4+7+5)÷6 = 24÷6 = 4

5)Mean =(10+11+9+12+8)÷5=50÷5 = 10

6)Mean = (1 + 2 + (-2)+1+(-2) )÷5 = -2÷5 = -0.4

find the angle p (add a explanation too)​

Answers

Step 1: Find the sum of the interior angles

Use this formula: 180 x (n - 2)

n is the number of sides of the polygon

Work:

180 x (4 - 2)

180 x 2

360

Step 2: Find the angle right above the 94 degree angle

The entire angle (a circle) is equal to 360 degrees. To find the part we're looking for (inside of the polygon), we need to subtract the angle we already know from 360.

Work:

360 - 94

266

Step 3: Set up an equation to find the missing angle p

We now know every angle except p! And we know the sum of the interior angles. Knowing this information makes it really easy to set up an equation.

360 = 12 + 75 + 266 + p

360 = 353 + p

p = 7 degrees

Does this answer make sense?

Yes! Although the drawing may not be to scale, it is very possible that angle p could be 7 degrees because of how 12 degrees looks on this graph.

if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).

so your equation will look like this:

Solving For The Length Of BC

1. [tex]15^{2} + 36^{2} =c^{2}.[/tex]      (solve for [tex]15^{2} and 36 ^{2}[/tex])

2. C= 225+1296      (add)

3.  C= 1521               (find the square root of 1521)
