Answer:

- [tex]\frac{2}{3}[/tex] and [tex]\frac{3}{4}[/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 ) = S(12, 9) and (x₂, y₂ ) = T(21, 3)

[tex]m_{ST}[/tex] = [tex]\frac{3-9}{21-12}[/tex] = [tex]\frac{-6}{9}[/tex] = - [tex]\frac{2}{3}[/tex]

Repeat with

(x₁, y₁ ) = S'(4, 3) and (x₂, y₂ ) = T'(7, 1)

[tex]m_{S'T'}[/tex]  = [tex]\frac{1-3}{7-4}[/tex] = - [tex]\frac{2}{3}[/tex]

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

(x₁, y₁ ) = R(24, 18) and (x₂, y₂ ) = S(12, 9)

[tex]m_{RS}[/tex] = [tex]\frac{9-18}{12-24}[/tex] = [tex]\frac{-9}{-12}[/tex] = [tex]\frac{3}{4}[/tex]

Repeat with

(x₁, y₁ ) = R'(8, 6) and (x₂, y₂ ) = S'(4, 3)

[tex]m_{R'S'}[/tex] = [tex]\frac{3-6}{4-8}[/tex] = [tex]\frac{-3}{-4}[/tex] = [tex]\frac{3}{4}[/tex]

Answer:

Answer B is the correct answer..

cot(theta)=cos(theta)/sin(theta)

Trignometric functions are the ratio of the sides of the triangle. The correct option from the following is cot(theta)= cos(theta)/sin(theta).

The trigonometric function gives the ratio of different sides of a right-angle triangle. There are six basic trigonometric functions,

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta= \dfrac{Sin \theta}{Cos \theta} =\dfrac{Perpendicular}{Base} \\\\\\Cosec \theta=\dfrac{1}{Sin\theta}=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta= \dfrac{1}{Cos\theta} = \dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{1}{Tan\theta}= \dfrac{Base}{Perpendicular}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.

As we know about the basic trigonometric functions, therefore, the options that is correct from the following option is cot(theta)= cos(theta)/sin(theta).

Answer:

The answer is 3 for the above question

Answer:

25 feet per second.

Step-by-step explanation:

Let s represent the speed of the water and r represent the radius of the whirlpool.

The speed in a whirlpool varies inversely with the radius. Therefore, we can write that:

[tex]\displaystyle s=\frac{k}{r}[/tex]

Where k is the constant of variation.

We know that the speed is 2.5 feet per second when the radius is 30 feet.

So, s = 2.5 when r = 30. Substitute:

[tex]\displaystyle 2.5=\frac{k}{30}[/tex]

Solve for k:

[tex]k=30(2.5)=75[/tex]

So, our equation is:

[tex]\displaystyle s=\frac{75}{r}[/tex]

Then when the radius is three feet, r = 3. Evaluate for s:

[tex]\displaystyle s=\frac{75}{(3)}=25\text{ feet per second}[/tex]

So, the speed of the water in a whirlpool with a radius of three feet is 25 feet per second.

Step-by-step explanation:

the y intercept is 2.5

(0,2.5)  (100 ,35)

the slope is (y2-y1)/(x2-x1)

m = (35-2.5)/(100-0)

m= (32.5)/100

m = .325

y = mx+b

y = .325x+2.5

let y =40  for 40 cars in all the spot

40 = .325 x + 2.5

subtract 2.5

37.5 =.325 x

divide by .325

37.5 /.325 = x

Explanation:

The left and right walls are mirror copies of one another, and they are also copies of the cross section as well. Think of a subdivision to divide one room into two smaller ones. That middle wall is the same as the left and right walls of the original larger room. Effectively, those two smaller rooms are blocks of their own we can pull apart or cut.

Answer:

Angle 1)  S = 12

Angle 2) Y = 18

Angle 3) R = 27

Angle 4) Z = 15

Angle 6) X = 13

Step-by-step explanation:

Angle 1

is a right angle, 90, use this to find s also

90 = (16s - 102)

90 + 102 = 16s

192/16 = s

12 = s

Angle 6

Angle 6 = 180

180 = 12x+24

180 - 24 = 12x

156 / 12 = x

13 = x

Angle 2

Angles 2 and 4 are a total of 90

Use this to find y

90 = (4y-9) + (y+9)

90 + 9 - 9 = 5y

90 = 5y

90/5 = y

18 = y

Angle 4

Angle 4 and 3 will be the same, us this to find z

2z - 3 = 4z - 33

2z - 3 - 4z = -33

-2z  = - 30

z = 15

Angle 3

3 and 5  together from 180

this mean

r + 5r + 18 = 180

6r = 180 - 18

6r = 162

r = 162 / 6

r = 27

Answer:

First choice

Step-by-step explanation:

The discontinuity is removable if by reducing the fraction that discontinuity doesn't continue to exist as a discontinuity.

Example of, (x-1)/(x-1) has a a discontinuity at x=1 and it's removable because the fraction reduces to 1 which doesn't have a discontinuity at x=1.

Example not of, (x-1)/(x-2) has a discontinuity at x=2 and it is not removable because we can't get rid of the x-2 factor in the denominator.

The first choice has a discontinuity at x=-1 and it is removable because x^2-x-2=(x-2)(x+1) and the x+1's will cancel on top and bottom making the point at x=-1 a removable discontinuity.
