<span>86.8954776543 rounded to the nearest millionth is 86.895478
The order after the decimal point goes like this:
tenths, hundredths, thousandths, ten thousandths, hundred thousandths, millionth</span>
Reformat the equation to be in terms of y.
4y= 3x-6
y=3/4x -6/4
The y intercept when x=0 is -6/4
The x intercept when y=0 is 2
Simply draw the graph using these two points
Let's remember orders of operations as we go through the craze of this problem.
We need to multiply or divide from left to right.
3w-6w+3w×7×7×6×5÷9+2
3w-6w+21w×7×6×5÷9+2
3w-6w+147w×6×5÷9+2
3w-6w+882w×5÷9+2
3w-6w+4,410w÷9+2
3w-6w+490w+2
-3w+490w+2
487w+2
To check that we simplified the expression right, I like to put in 1 for w and test it in the original expression and then the simplified expression (not needed).
487+2=489
3-6+3×7×7×6×5÷9+2=489
So that expression equals 487w+2.
Answer:
For number 9)
Interval notation ![(-\infty,3]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C3%5D)
For number 10)
Interval notation:
.
Step-by-step explanation:
On square roots you have to make sure the inside is positive or zero.
So the domain of the first one will come from solving

Subtract 6 on both sides:

Divide both sides by -2 (flip inequality when divide both sides by negative):

The domain is less than or equal to 3.
Interval notation ![(-\infty,3]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C3%5D)
On fractions you have to watch out for dividing by 0.
The domain is all real numbers except when 4x+2=0.
4x+2=0
Subtract 2 on both sides:
4x=-2
Divide both sides by 4:
x=-2/4
Reduce:
x=-1/2
The domain is all real numbers except when x=-1/2
Interval notation:
.
Answer:
Child's dosage=60 milligram
Step-by-step explanation:
The correct formula is below
C= a/(a+12) ∙ A
Where,
C = child’s dosage in milligrams
a = age of the child
A = adult dosage in milligrams
a=6 year old
A=180 milligrams
C= a/(a+12) ∙ A
=6/(6+12)*180
=6/18*180
=1/3*180
=60
Child's dosage in milligram=60 milligram
