64 - 9 = 55 \sqrt{55} = 7.4161984871
7.4161984871/2 ≈3.7
Answer:
A = 81.681409 (81.64 for 3.14 as pi) B = 4.65222141 (4.65458109 as 3.14 for pi) rotations
Step-by-step explanation:
To figure out how far one full rotation is (which is the circumference) you do the circumference formula: C = 2 pi r
C = 2 pi 13
C = 26pi
C = 81.681409
To figure out how many rotations C can fit into 380, divide 380 by C
380 / 81.681409 = 4.65222141
Answer:
12.1 years
Step-by-step explanation:
We are given that
Principal amount, P=$3000
Rate of interest, r=6.75% semi-annually
Amount, A=$6700
We know that
When r pays semi-annually
Where n=2
Using the formula
Taking ln on both sides we get
Answer:
Both are rational numbers
Both are Natural numbers
Both numbers are at the same distance of 1000
|1000-1003| = |997-1000|
Step-by-step explanation:
Both numbers have several things in common.
Both are rational numbers since they can be written as whole number fractions:
1003 = 1003/1
997 = 997/1
Both are Natural numbers, since they are non-negative integers.
Also both numbers are at the same distance of 1000.
| 997 -1000 | = 3
| 1000-1003 | = 3
Hello from MrBillDoesMath!
Answer:
Choice E and F
Discussion:
From the quadratic formula with a = 3, b = -1, and c = 6
x = ( -b +\- sqrt(b^2 - 4ac) ) / (2a) => substitute in a,b,c from above
x = ( -(-1) +\- sqrt((-1)^2 - 4(3)(6)) / (2*3) => discriminant = 1 - 72 = -71)
x = ( 1 +\- sqrt(-71))/ 6
which are choices E and F
Thank you,
MrB
