Answer:
28.2743 square feet (28 square feet, rounded)
Step-by-step explanation:
The area of a circle is given by the equation
Area = πr^2
Plug in 3 for the radius
Area= π(3)^2
3 squared is 9
Area= 9 π
Area= 28.2743 square feet
Rounded to the nearest square foot, the area of the circle is 28 square feet.
Answer:
6x+2y=-78
Step-by-step explanation:
8x-3y=-70
-2x+5y=-8
6x+2y=-78
Explanation:
A function is a relationship where any one x-value/input only has <u>one </u>corresponding y-value/output. (note: a y-value can have multiple x-values).
> This can be called "assigning one y-value to every x element".
The vertical line test places a line that would connect all y-values of an x-value (that is, if it were to have multiple y-values). If multiple points can be found along the vertical line, it is, therefore, by the definition of a function, not a function. (Because an x-value will have more than one y-value).
So, a graph that fails the vertical-line test does not represent a function because an x-value will correspond with more than one y-value.
hope this helps!!
Answer:
c=Px−5x4−7x3+2x2+3x
Step-by-step explanation:
Solve for
c
by simplifying both sides of the equation, then isolating the variable.
