y=2(cos(50=90n)=isin(50+90n))
take n=0 ,y=2(cos(50)+isin(50))
take n=1,y=2(cos(140)+ isin (140))
take n=2,y=2(cos(230)+ isin (230))
take n=3,y=2(cos(320)+isin(320))
Never true because if the product is 10 and the two numbers are 5 & 2 if you add them it won't give you 10 it will give you 7 so therefore the answer is never true
something through 1-10. i think its 7 but i rlly dont know. Sry.
Answer:
Candle B: 36 minutes
Candle C: 12 minutes
Step-by-step explanation:
Since Candle A burns for 72, and Candle B burns twice as fast, we can divide the 72 by 2 in order to get the time it burns. We will then see that Candle B burns for 36 minutes.
Candle C burns 3 times as fast as candle B so we can divide the 36 minutes it takes for candle B to burn by 3 to get how long it takes Candle C to burn. We then see that it takes 12 minutes for candle C to burn.
Hope this helps!
DE and EF are segments of the line DF, so they will add up to DF. This can be represented with this equation:
Combine like terms:
Add 15 to both sides:
Subtract 6x from both sides:
Divide both sides by 3 to get x by itself:
The value of x will be 8.
Plug this value of x into the expression for DF:
DF will equal 57.
