Annabelle is taking the Polar Express ALL the way to the North Pole! The Polar Express is 100 meters long and it takes 30 second
vlada-n [284]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To solve this, we will be doing a semi-alternate route, but it will get us to our answer...


400 / 100 = 4

30 / 4 = 7.5 seconds

60 * 60 * 7.5 = 27,000 meters per hour

<em></em><em>Lets plug it into our meters to miles formula...</em>

27,000 / 1,609.344 ~ 16.777 miles per hour


So...

The answer is:  The Polar Express was going 27,000 meters per hour (or roughly close to 16.777 miles per hour)...

How to determine if a function is even or odd calculus?
aalyn [17]
A function f(x) is even if f(-x)=f(x), and is odd if f(-x)=-f(x).

Example:

f(x)=x^2 is even, since f(-x)=(-x)^2=x^2=f(x).

g(x)=x^3-x is odd, since g(-x)=(-x)^3-(-x)=-x^3+x=-(x^3-x)=-g(x).

Home Depot wants to buy a new line of fertilizers. Manufacturer A offers a 22/19 chain discount. Manufacturer B offers a 25/14 c
Temka [501]

Answer: A is 36.82%. B is 35.5%

Step-by-step explanation: For manufacturer A 22/19 chian discount simply means 22% discount followed by 19% discount.

Therefore we have 100-22= 78 and 100-19=81.

The final price would be 0.78*0.81=0.6318

Therefore discount would be

1 - 0.6318=0.3682

Hence, percentage discount would be 0.3682*100%=36.82%.

For manufacturer B 25/14 chian discount means 25% discount followed by 14% discount. So we have 100-25=75% and 100-14= 86%

Final price would be 0.86*.75=0.645.

Discount= 1 - 0.645= 0.355.

Percentage discount would be 0.355*100%=35.5%.
