(6z²+z-1)(9z-5) polynomial equation

Answers

Hi there, (6z²+z-1)(9z-5)=(6z²+z+-1)(9z+-5)=(6z²)(9z)+(6z²)(-5)+(z)(9z)+(z)(-5)+(-1)(9z)+(-1)(-5)=54z³-30z²+9z²-5z-9z+5=54z³-21z²-14z+5. Therefore, the answer is 54z³-21z²-14z+5.

an elevator weighing 6,000 newton move up a distance of 10 meters in 30 seconds.what was the power of the elevators motor in watt and and in horsepower? btw: the part im having trouble with is getting the horse power

Answers


Energy added to the elevator (work) = (6,000 N) x (10 meters) = 60,000 joules.

Power = (energy) / (time)  =  (60,000 joules) / (30 seconds)  =  2,000 watts.

Now, here comes the part you've been waiting for:  The "horsepower".

We won't go through the history of 'horsepower', where it came from etc.
All you need to know is how it relates to 'watts'.

Here's that answer:   1 horsepower = 746 watts .

So the power of your elevator motor was

               (2000 watts) x (1 HP / 746 watts) = 2.681 horsepower  (rounded)

Obviously, that unit has nothing to do with real horses, if it ever did. 
It's just another name for 746 watts.

Now I WILL tell you how to remember that number ... because it's such a gas.
This story is not true either.  But I bet you'll remember it, for a while anyway:

From the detailed entries in Christopher Columbus' log during his
first voyage to the New World, modern scientists have been able to
calculate that when running before a wind of 30 mph, the main sail
of the Nina, the Pinta, or the Santa Maria would have developed
almost exactly 2.0 horsepower. 

Columbus discovered America in 1492 .

So each sailing horsepower on that voyage corresponded to 

                                                         1492 / 2 = 746 watts.

Sorry about that.

Izzy is making cookies. The recipe for 1/4 cup of butter and 3/8 cup of sugar. How much sugar would Izzy use if she used 1 cup of butter? Write your answer as a mixed number

Answers

To solve this equation, we have to set up a proportion, because we want to keep the ratio of butter to sugar equal between the two recipes.  Let x represent the amount of sugar that we are trying to find.

1/4 cup butter/3/8 cup sugar = 1 cup butter/ x cup sugar

To solve this proportion, we need to use cross products, or the multiplication of the numerator of one fraction by the denominator of the other, and setting them equal to one another.  If done properly, the resulting equation is:

1/4x= 3/8

Finally, we just need to divide both sides by 1/4, which is the coefficient of x, as we are trying to get x alone.  Your final answer is 

x=1.5.

Therefore, this means that if Izzy uses 1 cup of butter, she would use 1 1/2 cups of sugar.
