Answer:
Step-by-step explanation:
The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.
I think you might be referring to the definite integral,

Recall the definition of absolute value:

Then
if
, and
is
. So spliting up the integral at <em>x</em> = 1, we have

The rest is simple:

First, fill in the variables with the numbers given so that
2b-3c
will then become
2(4)-3(2)
next, you refer to the order of operations to simplify the problem down, the multiplication being the first doable operations in this problem.
8-6
and next operation being subtraction.
2
is the final answer
Answer:
The first option is correct.
Step-by-step explanation:
how do we multiply x - 9 by something? we put it in brackets
(x - 9) × (-3) = 51
that can be written like this
(x - 9)(-3) - 51
Counting the straight sides gives you 23 units and using the distance formula on the bottom side gives you about 11.18 units. 23+11.18=34.18 and round that to the nearest tenth to get the answer of 34.2 units.
