Simplify the expression. sine of x to the second power minus one divided by cosine of negative x
slega [8]

Answer:

the answer is the letter a) -sin x

Step-by-step explanation:

Simplify the expression.

sine of x to the second power minus one divided by cosine of negative x

(1−sin2(x))/(sin(x)−csc(x))

sin2x+cos2x=11−sin2x=cos2x

cos2(x)/(sin(x)−csc(x))csc(x)=1/sin(x)cos2(x)/(sin(x)− 1/sin(x))= cos2(x)/((sin2(x)− 1)/sin(x))sin2(x)− 1=-cos2(x)cos2(x)/(( -cos2(x))/sin(x))

=-sin(x)

Given the function f(x)=3^x, find the value of f^-1(27)
Shalnov [3]

This is asking you to solve the equation ...

... 27 = 3^x

You can use logarithms to find

... log(27) = x·log(3)

... log(27)/log(3) = x = 1.43136376.../0.47712125...

... x = 3

Or, you can use your knowledge of small cubes and match exponents.

... 3^3 = 3^x

... 3 = x

James spent $20.16 on comic books. Each comic book cost $0.72. After he read the comic books, James sold each one for $0.20 less
adell [148]

Answer:

$14.56

Step-by-step explanation:

<u><em>Steps to answering this question </em></u>

  1. Determine the total number of comics bought. This can be done by dividing the total amount spent on comics by the unit price of a comic
  2. Determine the selling price of the comic
  3. multiply the amount of comics bought by the selling price

the total number of comics bought = total amount spent on comics / per unit price of comics

$20.16 / $0.72 = 28

selling price = 0.72 - $0.20 = $0.52

Total amount received = selling price x total comics bought

$0.52 x 28 = $14.56
