Answer:
3.6, 3.60
Step-by-step explanation:
Equivalent decimal numbers may have different numbers of trailing zeros.
_____
<em>Comments on equivalents</em>
The number can be written in several different forms, including ...
and variations on these.
As a straight standard-form decimal number this representation (3.600) indicates it has 4 significant figures. <em>There is no other equivalent standard-form decimal number that will convey the same information regarding significant figures</em>. The form in scientific notation above will convey that information because it retains the two trailing zeros.
The mixed numbers can be considered to have a precision matching that of the fraction, but when we're concerned about the precision of the answer, we usually use a decimal or scientific notation presentation.
Solve the equation for y using the formula for slope: y + mx + b
2x^2 + 5y^2 = 14
5y^2 = -2x^2 + 14
y^2 = -2/5x^2 + 14/5
y = the sq root of -2x^2/5 + 14/5
There is no integer solution to the square root of a negative number.
