The common difference if there is one is the constant difference that occurs between any term and the term before it.... in this case:
There is no common difference,
dx=18,20,16,18 the difference or velocity is not constant...
d2x=2, -4,2 the acceleration is not constant...
d3x=-6,6 the thrust is not constant
Now we might be tempted to say that:
d4x=12 and say that that is constant and we COULD make a quartic equation fit all the data points, but without further data points in the sequence there is no mathematical proof that the quartic equation would produce accurate data points outside of the range given...
And solving a system of five equations for five unknowns is tedious for such a problem...a^4+bx^3+cx^2+dx+e=y
Answer:
Made a number line for this.
Step-by-step explanation:
To calculate for mass, simply multiply molar weight (MW)
and number of mols. The molar weight (MW) is in units of mg / mmol. Therefore
the mass is:
mass = (158 mg / mmol) (0.25 mmol)
mass = 39.5 mg
Answer:
39.5
Andy and Diana both got some pocket money from their aunt.
Andy spent all his money on collector's coins, he bought 5 of them.
Diana bought 3 of such coins, and she brought home 20 dollars of change.
after they came home their sister said "hah! I bet you I can find out how much each coin costs even if you don't tell me how much money your aunt gave you, if she gave you both the same amount!"
So, how much does each coin cost?
Answer:
x=110˚
Step-by-step explanation:
We need to first find the other degree inside the triangle
first add 45˚ and 65˚
which is 110˚
subtract 110˚ with 180˚
which is 70˚
So we find x since a straight line is 180˚
subtract 70 and 180
which is 110˚
Hoped I helped!
