Consider a sequence whose first three
snow_tiger [21]

Answer:

Below, depends if 27 is term number 1 or term number 0.  Answered for both cases.  

Step-by-step explanation:

The most common sequences are arithmetic and geometric, so lets check those first.

Arithmetic first since its the easiest.

to go from 27 to 21 we subtract 6, if we subtract 6 from 21 again we get to 15, which is what we need, so it is indeed arithmetic.

Explicit formula is basically of the form of y=mx+b with an arithmetic sequence.  the m is the common difference and b is the first term minus the common difference.  so lets fill those in.  y = -6x + 33

Then it usually has n as the x and y f(n) so we'll just put those in

f(n) = -6n + 33

This si as long as the first term is labeled as term number 1 and not term number 0.  if you have 27 as term 0 instead just make 33 back to 27, so f(n) = -6n + 27

Let me know if this doesn't make sense.

A high school football team won 80% of the games they played. If they played 35 games, how many games did they win?
crimeas [40]

Step-by-step explanation:

formuale \\ \%wom = total \: win \:  \times 100\% \div total \: matches \: played

let x be total much won

80\% = x \times 100\% \div 35 \\  x= 35 \times 80 \div 100 \\ x = 7 \times 4 \\ x = 28

so they team had won 28 matches.

I hope the team has best players : )

Town C is 2 miles east of town A and 2 miles south of Town B as in the figure at right. which of the following is the best estim
Ray Of Light [21]
Since C is 2mi east of A and 2mi south of B, the shortest distance from A to B would be a straight line which is equal to the hypotenuse of a right triangle with a base of 2mi and a height of 2mi..

d^2=x^2+y^2

d^2=2^2+2^2

d^2=4+4

d^2=2*4

d=√(2*4)

d=2√2 mi  (exact)

d≈2.83 mi  (to nearest hundredth of a mile)
