Answer:

D)

17,15,13,11

Step-by-step explanation:

From the formula

f(n) = f(n - 1) - 2 \\ f1 = 17 \\

  • we can deduce the next three terms as follows:
  • f(2) = f(2 - 1) - 2 \\ f(2)= f(1) - 2 \\ f(2) =  17 - 2 \\ f(2) = 15\\
  • f(3) = f(3 - 1) - 2 \\ f(3)= f(2) - 2 \\ f(3) =  15 - 2 \\ f(3) = 13\\
  • f(4) = f(4 - 1) - 2 \\ f(4)= f(3) - 2 \\ f(4) =  13 - 2 \\ f(4) = 11\\
  • Hence the sequence is; 17, 15, 13, 11,...

a shipping company charged $15 to ship a package and 5% to ensure the package what was total cost to ship this
postnew [5]

Answer:

15.75

Step-by-step explanation:

So we know 5% is 1/20 out of 100 (20x5=100) so then we need to set up the equation to find how much 5% of 15 is. Which is .75 cents. So we then add the 75 cents to the already $15 shipping fee to get an answer of 15 dollars and seventy five cents.

A white tailed deer can sprint at speeds up to 30 miles per hour. American bison can run at speeds up to 3,520 feet per minute.
bogdanovich [222]

Answer:

the Bision is 10 miles / hour faster if he could keep it up

Step-by-step explanation:

There are 60 minutes in an hour.

Therefore the bison can run [3520 feet / min] * [60 min ] =211288 feet in an hour.

Now you have to convert 212200 to miles. Do this by dividing by 5280

212200/5280 = 40 miles.

Kind of hard to believe isn't it. 40 miles is a long way when you are running it.

The bison is faster by 10 miles / hour.

This can be done all in 1 step if you know how to do dimensional analysis

3520 feet / minute * [ 60 min/ hour ] * [ 1 mile / 5280 feet] = 40 miles
