First let
, so that
to write the integral as
Now recall that
, so substituting
should do the trick. The integral then becomes
Answer:
-1
Step-by-step explanation:
Any variable without a visible coefficient means it has a coefficient of 1. Since it's negated, the coefficient is -1.
Answer:
Any line with the same slope. In this case the slope is 1. For example, y=x+4 is parallel to y=x+7.
To simplify i^82, divide 82 by. the answer is 20 with remainder 2
Answer:
Larger number:
16
Smaller number
3
Step-by-step explanation:
Larger number: 16
Smaller number: 3
Explanation:
Suppose the larger number is
a
and the smaller number is
b
.
You solve the following system of equations:
a⋅b=48
a−13=b
Since b is a −13, you can plug that into a⋅b=48, so...a⋅(a−13)=48
a 2−13a=48
a2−13a−48=0
Factor the polynomial:
(a−16)(a+3)=0
a=16 or a=−3a is positive so a=16.
We can now solve for b by plugging in a, so...16−13=b3=b We have a=16 and b=3, meaning that the larger number is 16 and the smaller number is 3.
