We can find the diameter of the circle by replacing some values in the formula for circumference. The formula for find the circumference is pi * d, where pi could equal 3.14 or 22/7 and d is the diameter. After dividing pi from both sides (I used 3.14), we have the total of about 21.01, which would be our diameter. We add 4 more feet into it, resulting in 25.01 feet, and we just multiply that by $0.45 to get the total price.
We get around $11.25 as our total price.
Answer:
Part A) The polynomial has three terms
Part B) The terms are 
Part C) Is a 2nd degree polynomial
Part D) The name of the polynomial is a 2nd degree trinomial
Step-by-step explanation:
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
we have
The polynomial has three terms
The terms are
therefore
The polynomial is a trinomial
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
The term is 
The highest exponent is the 2 so this is a 2nd degree polynomial
therefore
The name of the polynomial is a 2nd degree trinomial
The value will be minimum, the coefficient of x is positive, so it will curve up causing a minimum vertex
Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
most fuel efficient is Jean's car....it gets 30 miles per gallon
If order mattered, then there would be 6*5*4*3 = 30*12 = 360 different ways to form the committee. However, no single member outranks the other. Each member has equal ranking. So order does not matter.
Since order does not matter, we must consider all of the ways to arrange a single group of 4 people. That is 4! = 4*3*2*1 = 24 ways. We overcount by a factor of 24 when order doesn't matter which is why we divide the previous result (360) by 24 to get 360/24 = 15
Answer: 15
Note: you can use the combination formula n C r = (n!)/(r!*(n-r)!) with n = 6 and r = 4 to get the same answer
