Which expression is equivalent to sin(1.8x) sin(0.5x)?

Rasek [7]

Hum, this problem was difficult. You use the next expression to solve this problem. \[\cos (A - B) = \cos A \cos B + \sin A \sin B \] \[\cos (A + B) = \cos A \cos B - \sin A \sin B\] \[\cos (A - B ) - \cos (A +B ) =2 \sin A \sin B\] So \[\sin A \sin B = 0.5 \left( \cos(A - B) - \cos(A + B) \right)\] A = 1.8 x, B = 0.5 x \[\sin (1.8x) \sin (0.5x) = 0.5\left( \cos(1.8-0.5)x - \cos(1.8+0.5)x \right)\]\[= 0.5 \left( \cos(1.3x) - \cos (2.3x) \right)\] It's finish !!

A new television set was recently purchased for the common room in a Residence Hall for $428.00 including tax. If the tax rate i

prohojiy [21]

The price of the television set before taxes is $400

<h3>How to find the price of the television set before taxes.?</h3>

The given parameters are:

Price after tax = $428.00

Tax rate = 7%

The price of the television set before taxes is calculated as:

Price after tax = Price before tax * (1 + tax rate)

This gives

$428.00 = Price before tax * (1 + 7%)

Express the percentage as decimal

$428.00 = Price before tax * (1 + 0.07)

Evaluate the sum

$428.00 = Price before tax * (1.07)

Divide both sides by 1.07

Price before tax = $400

Hence, the price of the television set before taxes is $400

Solve this equation <br><br> 7b-6(11-2b)=10

Mkey [24]

7b-6(11-2b)=10
The first step is to distribute. Multiply each number inside the parentheses by -6.
7b + (-6*11) + (-6*-2b) = 10
7b - 66 + 12b = 10

Now combine like terms.
19b - 66 = 10

Add 66 to both sides.
19b = 76

Divide both sides by 19.
b = 4

The answer is b = 4.
