If sine of the quantity x plus y end quantity equals one half times sine of x plus radical 3 over 2 times cosine of x. What is t
miskamm [114]

The value of y from the given trig expression is pi/3 rad

<h3>Trigonometry identity</h3>

These identities are expressed in terms of sine, cosine and tangent

Given the expression

sin(x+y)=\frac{1}{2}sinx+\frac{\sqrt{3}}{2} cosx


Expand sin(x+y)

sin(x+y) = sinxcosy + cosxsiny

Compare both equations

cosy = 1/2

y = arccos(1/2)

y = 60 degrees

y = pi/3 rad

Hence the value of y from the given trig expression is pi/3 rad

Cooper earned $228.00 at his job when he worked for 10 hours. How much money did he earn each hour?
mote1985 [20]

Answer:

Cooper made $22.80 per hour.

Step-by-step explanation:

Since Cooper made a total of $228.00 within 10 hours, the money he made each hour is equivalent to the rate of change. That means that in order to get the amount of money made in one hour, you must first turn the ten hours into one using division. Since you divided ten into one using division, you divide the $228.00 by ten using division.

228 divided by 10 is 22.8, therefore Cooper is making $22.80 per hour.

Which expression is equivalent to 32 ⋅ 3−5? fraction 1 over 3 to the power 3 fraction 1 over 3 to the power 7 fraction 1 over 3
mars1129 [50]
Given expression 3² × 3⁻⁵

We will apply the power rule x^m*x^n=x^{m+n}

3² × 3⁻⁵ = 3²⁺⁽⁻⁵⁾ = 3²⁻⁵ = 3⁻³

We will then apply the power rule x^{-n} =  \frac{1}{x^n}

3⁻³ = \frac{1}{3^3}

Final answer: \frac{1}{3^3}
