Answer:

yes, it is a solution

Step-by-step explanation:

when you plug the values in, the expression is true

x = 2

y = 3

2 + 3 = 5

5 < 7

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]

Answer:

3.336

Step-by-step explanation:

I am 15% I think I did the wrong calculation.

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).

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.

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!

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
