Answer:
The diameter of the circle is 19 m
Step-by-step explanation:
The formula of the area of a circle is A = π r², where r is its radius
<em>To find the diameter from the area of the circle equate the formula of the area by the value of the area to find r, then multiply r by 2 because the diameter of a circle is equal twice its radius</em>
<em />
∵ The area of the circle is 90.25 π m²
∵ A = π r²
- Equate A by 90.25 π
∴ π r² = 90.25 π
- Divide both sides by π
∴ r² = 90.25
- Take √ for both sides
∴ r = 9.5
∵ The diameter of a circle is twice its radius
∴ d = 2 r
- Substitute r by 9.5
∴ d = 2(9.5)
∴ d = 19
The diameter of the circle is 19 m
Examining the table the functional notation is in the second option which is f ( x ) = x^2
<h3>How to determine the functional notations of the table</h3>
The table represents functions of input variables and the output variables.
The functional notation represents the relationship between the input and out variables
comparing the values and the function
f ( x ) = x^2
at x = -3 ⇒ f ( -3 ) = (-3)^2 = 9
at x = 0 ⇒ f ( 0 ) = (0)^2 = 0
at x = 1 ⇒ f ( 1 ) = (1)^2 = 1
This shows that f ( x ) = x^2 is the correct option

Answer:
H for sure
Step-by-step explanation:
It’s not a square but it’s a rectangle rectangles are parallel and rectangles are quadrilaterals
The answer is negative 4...4 to 0 has the same distance as -4 to O
Step-by-step explanation:
The initial value of a function is the output value of the function when the input value is 0. For example, if your function is tracking how much money you made over a certain amount of time, then the initial value would be however much money you had to begin with on day 0.
