The formula for the circumference of a circle is:
C=2πr
Since we know the radius is 14cm, we can solve for the circumference...
C=2π(14)
C=28πcm
C=<span>87.96cm</span>
It decreases
The further two objects are, the gravitational attraction decreases and the closer two objects are, the gravitational attraction increases
Answer: x = ± 1.68
Step-by-step explanation:
7x^4 = 56
x^4 = 56/7
x^4 = 8
Let a = x²
(x²)² = 8
(a)² = 8
a = ± √8
Now,
a = -√8
x² = -√8 has no real solution.
Taking +√8
a = √8
x² = √8
x = ± √(√8))
x = ± 1.68
Answer:
5/7
Step-by-step explanation:
In order to multiply fractions, multiply the numerators together and multiply the denominators together - the answers will be the numerators and denominators of the product, respectively. Also, remember that 5 can also be expressed as in fraction form since it is a whole number.
Knowing this, multiply like so:
·
Therefore, 5/7 is the answer.
