Answers

Answer:

See Below.

Step-by-step explanation:

We want to verify the equation:

[tex]\displaystyle \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}}[/tex]

Recall that tanθ = sinθ / cosθ. Likewise, cotθ = cosθ / sinθ. Then by substitution:

[tex]\displaystyle \begin{aligned} \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} & = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \\ \\ & \stackrel{\checkmark}{=} \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \end{aligned}[/tex]

Hence verified.

Given :

tan∅/1-cot∅ + cot∅/1-tan∅ = sin∅/cos∅ ÷ (1- cos∅/sin∅ ) + cos∅/sin∅ ÷ (1 - sin∅/cos∅)

To Do :-

To prove LHS = RHS

Proof :-

We know that ,

sin∅/cos∅ = tan∅cos∅/sin∅ = cot∅

On using above two in LHS ,

LHS = tan∅/1-cot∅ + cot∅/1-tan∅LHS = tan∅/1-cot∅ + cot∅/1-tan∅ = sin∅/cos∅ ÷ (1- cos∅/sin∅ ) + cos∅/sin∅ ÷ (1 - sin∅/cos∅) LHS = RHS

Hence proved !

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees

during the work week mrs. Jamison drive 75 miles each way to work if she works 21 days each month how far does she drive for the work during the month​

Answers

Answer:

See below:

Step-by-step explanation:

So, the question asks how far she drives in a month, this probably includes going to work and coming back. Therefore, each day takes 2 times 75 which is 150!

Now, we know she goes 150 miles each day going to work and coming back. We can now multiply that by 21 to get out answer.

We can split 21 into 10 * 2 + 1 for our convenience.

150 times 10 is 1500 and that times two is 3000 added by 150 is 3150.

Then we get out answer; 3150 miles!

The value of the variable 'x' by the corresponding angles property will be 10.

What is an angle?

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.

From the diagram, by the corresponding angles property, the equation is given as,

4x = 3x + 10

Simplify the equation, then we have

4x = 3x +10

x = 10

The value of the variable 'x' by the corresponding angles property will be 10.

A board is 22.5 Inches long. How long is the board in centimeters? Use the following conversion: 1 Inch is 2.54 centimeters.

Answers

Answer:

57.15

Step-by-step explanation:

22.5*2.54 is 57.15

The board is 57.15 centimeters long.

To convert the length of the board from inches to centimeters, we need to use the conversion factor of 1 inch equals 2.54 centimeters.

Given that the board is 22.5 inches long, we can multiply this value by the conversion factor to find the equivalent length in centimeters.

Length in centimeters = Length in inches × Conversion factor

Length in centimeters = 22.5 inches × 2.54 centimeters/inch

Calculating this expression:

Length in centimeters = 57.15 centimeters

Therefore, the board is 57.15 centimeters long.

(del^(2)z)/(delx^(2))-4(del^(2)z)/(delxdely)+4(del^(2)z)/(dely^(2))=e^(2x+y)

Answers

Using Dz and D'z to denote partial derivatives of z with respect to x and y respectively, the equation becomes (D^2 -1)z=0 or (D-1)(D+1)z=0. Put (D+1)z = u(x,y). Then we have (D-1)u =0. The general solution of this equation is u(x,y)=A(y).e^x, where A(y) is an arbitrary function of y, because we have integrated a partial derivative of u with respect to x, and we have to take an arbitrary function of y instead of an arbitrary constant.

Now the original equation becomes

(D+1)z=A(y)e^x and we integrate it with respect to x, giving ze^x = Int[e^x.A(y).e^x.dx] + B(y), (for another arbitrary function B(y)) = (1/2)e^(2x).A(y) +B(y) or

z(x,y) = B(y)e^(-x)+[A(y)e^x]/2 or

z = B(y)e^(-x) + C(y)e^x. Hence putting x=0,

e^y = B(y)+C(y) and Dz= -e^(-x)B(y) + e^x.C(y). Again putting x=0, we get 1 = -B(y) + C(y). Solving the two equations in B(y) and C(y), we have C(y) = (1+e^y)/2, and B(y) = (e^y -1)/2. Hence the required solution is

z = [(e^y -1).e^(-x)]/2 + [(e^y +1).e^x]/2 =

z = (e^y)cosh(x) + sinh(x).
