Verify the identity. 4 csc 2x = 2 csc2x tan x

vlada-n [284]

Step-by-step explanation:

$4csc(2x) = 2csc^2(x) tan(x)$

We start with Left hand side

We know that csc(x) = 1/ sin(x)

So csc(2x) is replaced by 1/sin(2x)

$4 \frac{1}{sin(2x)}$

Also we use identity

sin(2x) = 2 sin(x) cos(x)

$4 \frac{1}{2sin(x)cos(x)}$

4 divide by 2 is 2

Now we multiply top and bottom by sin(x) because we need tan(x) in our answer

$2\frac{1*sin(x)}{sin(x)cos(x)*sin(x)}$

$2\frac{sin(x)}{sin^2(x)cos(x)}$

$2\frac{1}{sin^2(x)} \frac{sin(x)}{cos(x)}$

We know that sinx/ cosx = tan(x)

Also 1/ sin(x)= csc(x)

so it becomes 2csc^2(x) tan(x) , Right hand side

Hence verified

What are the zeros of the polynomial function f(x)=x(x-4)(x+9)? HELP NEEDED!!!!

Kipish [7]

Answer: 0, 4, -9

Set the equation equal to zero.

x(x - 4)(x + 9) = 0

Solve for x by setting each factor equal to zero.

The factors in the equation are x, (x - 4), and (x + 9).

x = 0

(x - 4) = 0

x = 4

(x + 9) = 0

x = -9

The zeros of the function are 0, 4, and -9.

1. Find the possible values for s in the inequality 12s – 20 ≤ 50 – 3s – 25

hjlf

12s - 20 < 50 - 3s - 25

12s - 20 < 25 - 3s
+3s. +3s

S cancels

15s - 20 < 25
+ 20. +20

15s < 45
/15. /15

S < or equal to 3
