Please simplify the following trigonometric identity.
lesya692 [45]

<u>Examining the question:</u>

We are given the expression:

\frac{1}{Sec(\alpha)-Tan(\alpha)}

We know from Basic trigonometry that:

Sec(\alpha) = \frac{1}{Cos(\alpha)}

Tan(\alpha) = \frac{Sin(\alpha)}{Cos(\alpha)}

<u>Simplifying the expression:</u>

Replacing these values in the given expression, we get:

\frac{1}{\frac{1}{Cos(\alpha)} -\frac{Sin(\alpha)}{Cos(\alpha)} }

Since the denominator of both the values in the denominator is the same:

\frac{1}{\frac{1-Sin(\alpha)}{Cos(\alpha)} }

We know that \frac{1}{\frac{a}{b} } = \frac{b}{a}, using the same property:

\frac{Cos(\alpha)}{1-Sin(\alpha)}

and we are done!

I don’t know what to do

Answer:

x = 7

y = 12

Step-by-step explanation:

To do this question you have to know your exponent rules, but also you need to know how to add fractions.

To multiply

6^(1/3) × 6^(1/4)

you can keep the 6 and just add the exponents.

That's why the answer is set up on the form 6^(x/y)

To add fractions, you need a common denominator, it is 12.

1/3 is 4/12.

1/4 is 3/12.

So 1/3 + 1/4

is the same as:

4/12 + 3/12

= 7/12

7/12 is the exponent you are looking for.

x = 7 and y = 12.

6^(1/3) × 6^(1/4)

=6^(7/12)

Hatshy [7]

Answer:

$2 for 1 rose bush and $2 for one shrub

Step-by-step explanation:

32=2x+14y

26=11x+2y

32=2(2)+14(2)

32=4+28

32=32

26=11(2)+2(2)

26=22+4

26=26

Since both equations come out correct the cost of 1 rose bush is 2 dollars and the cost of one shrub is 2 dollars. kinda cool
