A relation is a relationship between sets of values. In math, the relation is between the x-values and y-values of ordered pairs. The set of all x-values is called the domain, and the set of all y-values is called the range.
Answer:
Step-by-step explanation:
Area of the figure = area of the down triangle + area of trapezium + area of the upper triangle
Down triangle:
Base b = 8 in
Height = 6 in
= 24 in²
Trapezium:
bases a = 4 in & b = 6 in
Height h = 5 in
= 25 in²
Area of the upper triangle:
Base b = 6 in
Height = (8 - 5) = 3 in
= 9 in²
Area of the figure = 24 + 25 + 9 = 58 in²
Answer:
sin^2α
Step-by-step explanation:
I will just pose x instead of alpha here to make things simpler
we know that sin^2x = 1 - cos^2x so...
we can rewrite using trigonometric identities (tan = sin/cos)...
Answer:
Third inequality has dashed boundary.
Step-by-step explanation:
An equality has dashed boundary on graphing when it strictly less than or strictly greater than Symbolically ( < or > sign in the inequality)
boundary line is is solid line when the inequality is with symbol of equality also ( < = or > = )
Here we can see that all the inequalities except third one has symbol less than or equal to or greater than or equal to . And third inequality is with
symbol > (greater than ) that mean strictly less than ,therefore on graphing
third inequality gives dashed line boundary.
