Check out the attached image below for the steps on how to do this derivation.

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

Some notes:

  • For line 2, I used the identity \sec^2\theta = \tan^2\theta+1
  • For line 7, I applied the reciprocal to both sides.
  • For line 8, I used the identity \cot\theta = \frac{1}{\tan\theta}
  • For line 9, I used the identty \cot^2\theta = \csc^2\theta - 1 which is a rearrangement of \cot^2\theta + 1 = \csc^2\theta
  • For lines 1 through 6, I'm isolating tan^2, so that I can later transform that into cot^2, which leads to csc^2. All of this is done through the identities mentioned above.

A piece of fabric is 1/3 yard by 3 5/8 yards. Irma solves 1/3⋅3 5/8 to find the area of the fabric in square yards. Enter number
Harlamova29_29 [7]

For this case we have:


The area of the piece of fabric is given by A = a * b


Where


a = \frac{1}{3}yards


b = 3 \frac{5}{8}yards


Substituting in the formula of the area we have:


A = \frac{1}{3}* 3 \frac{5}{8}\\

A = \frac{1}{3}* (3 + \frac{5}{8})\\

A = 1 + \frac{5}{24}


A = 1\frac{5}{24}yards ^ 2\\

Thus, the area of the piece of fabric is given by: A = 1\frac{5}{24}yards ^ 2\\

Answer:


A = 1\frac{5}{24}yards ^ 2\\

Answer the question math
Lerok [7]

Answer:

7y-10

Step-by-step explanation:

9y-\frac{1}{2}\left(4y+20\right)

To simplify this expression, first use the distributive property to distribute \frac{1}{2}.

9y-\frac{1}{2}(4y)+-\frac{1}{2}(20)

Simplify.

9y+-2y+-10

Combine like terms, 9y and -2y.

7y-10

The simplification of 9y-\frac{1}{2}(4y+20) is 7y-10.

I hope this helps ^^

Good luck
