Answer:
(n-2)(n+2)
Step-by-step explanation:
The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.
(n^2 -4) = (n -2)(n +2)
Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...
(n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2
This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).
If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).
C kinetic energy. As it loses potential energy, it gain kinetic energy
A linear function represents a line, a quadratic function represents a parabola.
The dots fit a parabolic behaviour (they are descendent at the beginning, they reach a minimum and then start growing again), so a quadratic model could fit the dots much better than a linear one.
Answer:
44.1
Step-by-step explanation:
180-102-28=50
Sin(28°)/27=.0173
Sin(50°)/.0173=44.056
The correct expression of the inequality expression is 21% > 1/5
<h3>How to complete the inequality expression?</h3>
From the question, the expression is given as
21% < or > 1/5
We start by converting the above expression to the same form
Take for instance, we convert the expressions to decimals
So, we have
21% = 0.21
1/5 = 0.20
This gives
0.21 < or > 0.20
When the above numbers are compared, we have
0.21 is greater than 0.20
This means that we make use of the inequality symbol >
So, we have
0.21 > 0.20
Substitute 21% = 0.21 and 1/5 = 0.20
21% > 1/5
Hence, the complete inequality is 21% > 1/5
