Solve the equation: Sin2x - Sinx = 0
Viktor [21]
We know that sin2x=2sinxcosx 
(search the net for proof if you wish) 

So the original equation becomes

2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get: 

sinx(2cosx-1)=0 
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2

sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer

3. The three salespeople for a local advertising firm are Lola, Ahmed, and Tommy. Lola sold $2030 in ads, Ahmed sold $1540, and
Salsk061 [2.6K]
3. (a)

Add the three totals.

Total sales for all three: $2030 + $1540 + $1800 = $5370

Now divide each person's sales by the total sales to find each person's fraction of the sales.

Lola: 2030/5370
Ahmed: 1540/5370
Tommy: 1800/5370

3. (b)

Multiply each fraction from part (a) by $100.

Lola: 2030/5370 * $100 = $37.80
Ahmed: 1540/5370 = $28.67
Tommy: 1800/5370 = $33.52

Express the -0.345 in the form of p\q and reduce it to the lowest term​
Mamont248 [21]

Answer:

-69/200

Step-by-step explanation:

-0.345 is in decimal form.

In Fractional form (p/q)

=-345/1000

To simplify, divide the numerator and the denominator by the G.C.D(Greatest Common Divisor) of p and q.

In this case,G.C.D of 345 and 1000 is 5.

Simplified form=-69/200 [ANS]
