Simplify the expression cos x cot x+ sin x please select the best answer from the choices provided a.0, b.csc x, c. Tan x, d sec
expeople1 [14]

Answer:

cot x = \frac{cos x}{sin x}

cos x \frac{cos x}{sin x} + sin x

\frac{cos^2 x}{sin x} +sin x

sin^2 x + cos^2 x =1

Solving for cos^2 x we got cos^2 x =1 -sin^2 x and replacing this we got:

\frac{1-sin^2 x}{sin x} +sin x

\frac{1}{sin x} -\frac{sin^2 x}{sin x} +sin x

csc x -sin x + sin x = csc x

And then the best option for this case would be:

b.csc x

Step-by-step explanation:

For this case we have the following expression given:

cos x cot x + sin x

We know from math properties that the definition for cot is cot x = \frac{cos x}{sin x}

If we use this definition we got:

cos x \frac{cos x}{sin x} + sin x

\frac{cos^2 x}{sin x} +sin x

Now we can use the following identity:

sin^2 x + cos^2 x =1

Solving for cos^2 x we got cos^2 x =1 -sin^2 x and replacing this we got:

\frac{1-sin^2 x}{sin x} +sin x

\frac{1}{sin x} -\frac{sin^2 x}{sin x} +sin x

csc x -sin x + sin x = csc x

And then the best option for this case would be:

b.csc x

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium
bazaltina [42]
First, we define variables:
 x: small hat
 y: medium hat
 z: large hat
 We now write the system of equations:
 x + y + z = 47
 5.50x + 6y + 7z = 302
 -3x + y = 0
 We can write the system in matrix form as:
 Ax = b
 Where,
 A = [1  1  1; 5.50  6  7; -3  1  0]
 b = [47;  302;  0]
 x = [x;  y ;  z]
 Solving the system we have:
 x = 6
 y = 18
 z = 23
 Answer:
 
the coach did purchase 23 large hats
 
d. 23
