Answer:

Y=3/7x+8 and y=-7/3x-34/3(11 1/3)

Step-by-step explanation:

for the perpendicular line, the slope is the opposite inverse (3/7) and since 3/7×-7=-3, -3+8=5, hence, y=3/7x+8.

for the parallel line the slope is the same, and since -7/3×-7=49/3,

and 49/3-15/3(5)=34/3, the equation is y=-7/3-34/3

Answer:

n = -4, -1/3.

Step-by-step explanation:

3n^2 + 13n+4= 0

3n^2 + 12n + n + 4 = 0

3n(n + 4) + 1(n + 4) = 0

(3n + 1)(n + 4) = 0

n = -4, -1/3.

Answer:

36.5

Step-by-step explanation:

To find the median, list the ages in order from smallest to largest

23, 26 , 26,  35, 38 , 45, 50 ,63

Then find the middle

23, 26 , 26,  35,    38 , 45, 50 ,63

It is halfway between 35 and 38

(35+38)/2 = 36.5

The median is 36.5

Answer:

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. Gravity pulls denser air and water downward, forcing less dense air and water to move upward.

Interior angles of a polygon = (sides - 2) × 180

Exterior angles are always 360

Please Mark as Brainliest if you found it helpful!

The measures of an exterior angle are 2520°, and an interior angle is 360° in the given regular polygon with 16 sides.

An interior angle is defined as an angle produced on the inside of a polygon by extending the sides of the polygon.

Interior angles of a polygon = (sides - 2) × 180°

To determine the measures of an exterior angle and an interior angle given a regular polygon with 16 sides.

Interior angles of a polygon = (sides - 2) × 180°

In this case, the number of sides is 16

Interior angles of a polygon = (16 - 2) × 180

Interior angles of a polygon = (14) × 180

Interior angles of a polygon = 2520

And, Exterior angles are always 360° in the regular polygon.

Similarly, the other regular polygons :

A regular polygon with 24 sides: Int 3960, Ext 360

A regular polygon with 30 sides: Int 5040, Ext 360

A regular polygon with 14 sides: Int 2160, Ext 360

A regular polygon with 22 sides: Int 3600, Ext 360

A regular polygon with 40 sides: Int 6840, Ext 360

Given:

Total number of students = 20

The marks of the students are 40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37 and 40.

To find:

The frequency distribution table with class size 10.

Solution:

We have, the marks of 20 students.

40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37, 40

Here,

Minimum value = 12

Maximum value = 48

We nee class intervals of size 10. So, the required class intervals are 10-20, 20-30, 30-40, 40-50. In these intervals, lower limit is excluded but the upper limit included.

The required frequency distribution table is

Class intervals      Marks                                                  Frequency

10-20                    12, 15                                                            2

20-30                   22, 27, 20, 25                                             4

30-40                   36, 30, 31, 34, 36, 39, 36, 37                      8

40-50                   40, 41, 43, 48, 46, 40                                  6

Total                                                                                        20

Therefore, the frequency distribution table is

Class intervals:      10-20        20-30        30-40         40-50         Total

Frequency      :          2                4                8                6                20

Answer:

f*g(x) =  -25

Step-by-step explanation:

f*g(x) = f(x) * g(x) = x² * (3x + 14)

f*g(x) = (-5)² * (3*-5 +14) = 25 * (-1) = -25

Answer:

x²+6x +8 ≥ 195

Step-by-step explanation:

The age of C is represented by  c=  x .

Building B was built two years before building C.

Age of Building B   b = x+ 2

Building D was built two years before building B

Age of Building d= x+4

The product of the building B’s age and building D’s age is at least 195.

b*d ≥ 195

≥ means product is greater than or equal to 195 at least 195

Putting the values of b and d

(x+ 2) (x+4) ≥ 195

It can be further solved

x²+6x +8 ≥ 195

Answer:

x^2+6x+8>195

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

Explanation:

The phrasing "translated along <4,6>" is another way of saying "shift 4 to the right, shift 6 up"

In general, "translated along <m,n>" is the same as writing [tex](x,y) \to (x+m, y+n)[/tex]. If m is positive, then we shift m units to the right. If m is negative, then we shift to the left. The same story happens with the n, but we focus on the y coordinate.

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

With all that in mind, starting at F(-5,-9) and translating along <4,6> has us arrive at (-1, -3). Add 4 to the x coordinate and add 6 to the y coordinate.

We can say

[tex](x,y) \to (x+4,y+6)\\\\(-5,-9) \to (-5+4,-9+6)\\\\(-5,-9) \to (-1,-3)\\\\[/tex]

Showing that (-5,-9) moves to (-1,-3)

This is after the first translation, but there's a second translation.

We'll apply the same idea, but different numbers this time

[tex](x,y) \to (x+3,y+5)\\\\(-1,-3) \to (-1+3,-3+5)\\\\(-1,-3) \to (2,2)\\\\[/tex]

So (-1,-3) moves to (2,2)

Overall we have

Therefore, the original point ends up at (2,2) which is the final answer

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

Extra info:

A nice shortcut is that the vectors <4,6> and <3,5> can be added to get <4+3,6+5> = <7,11>. So overall, we're shifting 7 units to the right and 11 units up when we combine the two translation vectors.
