A=22/10
A=integral(a,b) [f(x)-g(x)]dx
Since the function is even (the function is mirrored over the y axis) we can evaluate the integral from 0 to 1 and then multiply our answer by 2 since we have the same area on each side of the y axis.
We get A=2*int.(0, 1)[(x^2)-(-2x^4)]dx
Now we can integrate by term.
2*[int.(0, 1)[x^2]dx+int(0, 1)[2x^4]dx]
Now factor out constants.
2*[int(0,1)[x^2]dx+2int(0,1)[x^4]dx]
Now integrate.
2*[(x^3/3)|(0,1) + 2*(x^5/5)|(0,1)]
Now solve.
2*[(1/3)+2*(1/5)]
=22/10

Answer:
<em>D.) It has a common difference of 3.8</em>
Step-by-step explanation:
When you subtract 
you get a common difference, the same goes for the other values: when you subtract the previous term from the next, you get a common difference of positive 3.8
<span>distance=6390km; time=9 hrs; rate=710kph
With the wind Data:
distance=5150km; time=5hrs; rate=1030kph
EQUATIONS:
airspeed+jetstream=1030
airspeed-jetstream=710
Subtract these equations to get:
2jetstream=320kph
jetstream=160mph </span>

Answer: 8+y
Step-by-step explanation:
the word "SUM" in maths means the answer to an "ADD".
It is always used with the word "AND" so you know which two (or more) numbers are being added together.
The SUM of 8 AND y, means add 8 and y together.
8
+
y
