Write the expression as the sine, cosine, or tangent of an angle. sin 5x cos x - cos 5x sin x

mrs_skeptik [129]

Answer:

sin 5x cos x - cos 5x sin x = sin(4x)

Step-by-step explanation:

Given that the trigonometric expression,

sin 5x cos x - cos 5x sin x

Here we use the "sum and difference formulas"

Sum and Difference Formulas

sin(A+B)=sin A cos B + cos A sin B

sin(A-B)=sin A cos B - cos A sin B

cos(A+B)=cos A cos B - sin A sin B

cos(A-B)=cos A cos B + sin A sin B

So,

sin 5x cos x - cos 5x sin x = sin (5x - x)

sin 5x cos x - cos 5x sin x = sin(4x)

That's the final answer.

A man earned x pesos in 10 days and spent y pesos during each of those days. Write an expression to determine how many pesos he

Vsevolod [243]

Answer: $\dfrac{x}{10}-y$

Step-by-step explanation:

Given : A man earned x pesos in 10 days and spent y pesos during each of those days.

i.e. Total earning in 10 days = x

Earning per day = $\dfrac{x}{10}$ [By unitary method] (1)

Money spent per day =y (2)

We know that

$\text{Savings = Money earned - Money spent}$

i.e. Subtract (2) from (1), we get

$\text{Savings = }\dfrac{x}{10}-y$

Hence, the expression to determine how many pesos he saved per day will be:-

$\dfrac{x}{10}-y$
