Answer:
Conjecture : 2xy / ( x + y ) ≤ √xy
Step-by-step explanation:
Harmonic mean of x and y = 2xy/( x + y )
<u>Formulate a conjecture about their relative sizes </u>
we will achieve this by computing harmonic and geometric means
Geometric mean = √xy
harmonic mean = 2xy/( x + y )
Conjecture : 2xy / ( x + y ) ≤ √xy
attached below is the proof
Answer:
D. $26,743.80
Step-by-step explanation:
25230(1+ .06(1))
type that in a calculator and you will get the correct answer of D.
Also I literally learned this 5 minutes ago and my teacher said I was correct.
Answer:
87.92
Step-by-step explanation:
you have your radius 14 inches to get the answer is
1: pie is 3.14
2: circumference is 2× 3.14×14
3: 3.14×14
4: 43.96 × 2
Answer:
8 quarters and 12 nickles
Step-by-step explanation:
8*25=2.00
12*.05=.60
Factor by using the rational roots test, and find that -2 is a root.
Replace X with -2 and simplify each term.
Divide the polynomial by (x+2)
The final answer becomes x = -2 and x = -1/2 +/-√3/2i
The first choice is the correct one.
