Find the value of the csc 40° using your calculator. (I've been having a hard time with this, so it'd be helpful if anyone could

SCORPION-xisa [38]

The correct answer is: 
C 1.556.

Explanation:
This can be found by locating the csc button on your calculator. Typically it is located as the second option below the sin button as it is the inverse function.
If you cannot locate the csc button on your calculator, you can also use $\frac{1}{sin(40)}$ as csc is its inverse.

Also, it is helpful to note that some calculators have both a degrees and a radians mode for trigonometric functions. You will need to make sure that you are in degrees in order to use a calculator to solve this.

Simplify the rational Expression

qaws [65]

Answer:

$\frac{x^2+2x}{x-3}$

Step-by-step explanation:

We need to factor out numerator and denominator in order to simplify the rational expression by cancelling common factors.

Numerator : x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)

Denominator (factoring by grouping):

x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)

Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:

x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)

$\frac{x^2+2x}{x-3}$

75 = 0

80 = 3 dots because there are 3 students that got a 80 %

85 = 3 dots because there are 3 students that got a 80 %

90 = 4 dots because there are 4 students that got a 90 %

95 = 3 dots

100+ = 0 dots
