X/58.65 = 15/100
(58.65*15)/100 = tip
Multiplying and dividing with conjugate of 2+i in the given expression, we get(3+ 4i)(2-i)/(2+i)(2-i)=(6-3i+8i-4i^2)/(4-i^2)=(10+5i)/(4+1)=(10+5i)/5=2+i=a+bi<span>Thus a=2</span>
The domain of a function is the set of values of the independent variable for which the function is defined. The square root function is defined for all non-negative real numbers. So, ...
The domain of
y = √x
is all real numbers greater than or equal to zero. (x ≥ 0)
_____
In some cases, there may be other limits on the domain of a function. A function may be defined for all values of mass, for example, but is of no practical use for values of mass greater than the mass of the known universe (or planet Earth, perhaps).
Answer:
Graphs come in all sorts of shapes and sizes. In algebra, there are 3 basic types of graphs you'll see most often: linear, quadratic, and exponential. Check out this tutorial and learn how to determine is a graph represents a linear, quadratic, or exponential function!
Step-by-step explanation:

To find the mean of a number sequence, add all the numbers together and divide them by the number of numbers used...
10 + 11 + 10 + 10 + 8 = 49
49 ÷ 5 = 9.8
The mean does not match 10, so make up numbers untill it matches.
10 + 11 + 10 + 10 + 8 + 6 ÷ 6
= 10 !
The anwser would be y = 6
