If X and Y are Boolean variables, then X + Y represents disjunction (OR) and XY represents conjunction (AND), and X' denotes the negation (NOT). So X + Y = 1 if either X = 1 or Y = 1, and XY = 1 only if both X = 1 or Y = 1.

Now,

(X + Y) (X + Y') = XX + YX + XY' + YY'

… = X + X (Y + Y') + 0

… = X + X

… = X

or in table form,

\begin{array}{c|cccc}X&1&1&0&0\\Y&1&0&1&0\\Y'&0&1&0&1\\X+Y&1&1&1&0\\X+Y'&1&1&0&1\\(X+Y)(X+Y')&1&1&0&0\end{array}

How can we use the graph of a logarithmic function to​ verify the domain of a function?PLEASE HELP
guajiro [1.7K]
The function y = log 2 x has the domain of set of positive real numbers and the range of set of real numbers. Remember that since the logarithmic function is the inverse of the exponential function, the domain of logarithmic function is the range of exponential function, and vice versa.

Determine the unknown angle measures, to the nearest degree, in the diagram provided.
serg [7]

Answer:

a is <u>5</u><u>3</u><u>.</u><u>8</u><u>°</u><u>,</u> and b is <u>3</u><u>6</u><u>.</u><u>2</u><u>°</u>

Step-by-step explanation:

Using sine trig rule:

{ \boxed{ \bf{ \sin(b) =  \frac{opposite}{hypotenuse}  }}}

{ \tt{ \sin(b) =  \frac{78}{132}  }} \\  \\ { \tt{b =  { \sin }^{ - 1}( \frac{78}{132} ) }} \\  \\ { \tt{b = 36.2 \degree}}

Summation of angles of triangle:

{ \tt{a + b + 90 \degree = 180 \degree}} \\ { \tt{a + 36.2 \degree + 90 \degree = 180 \degree}} \\ { \tt{a = (180 - 36.2 - 90) \degree}} \\ { \tt{a = 53.8 \degree}}

I need help <br><br>what is the function of this graph i cant figure it out
Natali5045456 [20]
If you have covered function tranformations

is an exponential function, likely something like y =2^x  but shifted upwards by 3 units and with a coefficient multiplying "x" something like "2"

so... try graphing in your calculator y = 2^{2x}+3
