Find the value of cos 28°​cos 62°​– sin 28°​sin 62°​
Romashka [77]
<h2>Answer:</h2>

cos 28°​cos 62°​– sin 28°​sin 62°​ = 0

<h2>Step-by-step explanation:</h2>

From one of the trigonometric identities stated as follows;

<em>cos(A+B) = cosAcosB - sinAsinB             -----------------(i)</em>

We can apply such identity to solve the given expression.

<em>Given:</em>

cos 28°​cos 62°​– sin 28°​sin 62°​

<em>Comparing the given expression with the right hand side of equation (i), we see that;</em>

A = 28°

B = 62°

<em>∴ Substitute these values into equation (i) to have;</em>

<em>⇒ cos(28°+62°) = cos28°cos62° - sin28°sin62°</em>

<em />

<em>Solve the left hand side.</em>

<em>⇒ cos(90°) = cos28°cos62° - sin28°sin62°</em>

⇒ 0 = <em>cos28°cos62° - sin28°sin62°     (since cos 90° = 0)</em>

<em />

<em>Therefore, </em>

<em>cos28°cos62° - sin28°sin62° = 0</em>

<em />

A gallon of milk cost $2.90 in 2002. In 2018, it cost
lutik1710 [3]

Answer:

<em>The cost of a gallon of milk changed 31%</em>

Step-by-step explanation:

<u>Percent Change</u>

Is the difference between two values of the same variable in different times or conditions, expressed as a percentage of the original value.

The formula is:

\displaystyle Pc=\left |\frac{v1-v2}{v1}  \right |\cdot 100\%

Where

v1 = original value

v2 = final value

The gallon of milk cost v1=$2.90 in 2002 and v2=$3.80 in 2018. The percent change is:

\displaystyle Pc=\left |\frac{2.90-3.80}{2.90}  \right |\cdot 100\%

\displaystyle Pc=\left |\frac{-0.9}{2.90}  \right |\cdot 100\%

Pc = 31%

The cost of a gallon of milk changed 31%
