The area of a circle is <u>(pi) x (the circle's radius)</u>²

The circle's radius is (1/2) of (its diameter).

Area = (pi) x (12/2 inches)² =

            (pi) x (6 inches)² =

           (3.14) x (36 square inches)  =  <em>113 square inches</em>  (rounded)

Cheryl scored 7 points on free throws and the rest of her points on 2-point goals. If g represents the number of 2-point goals s
Gwar [14]
2 points per goal, so 2g. 
Add + 7 to that because she scored 7 points of free throws.

This means the answer would be A. 2g + 7.

Graph each absolute value function. State the domain, range, and y-intercept.
Paraphin [41]

Answer:

i)D:x\in R

ii)R: y\ge-3

iii) Y-int:(0,-1)

Step-by-step explanation:

i) The given absolute value function is;

f(x)=|x+2|-3.

The absolute value function is defined for all real values of x.

The domain is all real numbers.

ii) The range is all y-values that will make x defined.

The given function,

f(x)=|x+2|-3.

has vertex at, (-2,-3) and opens upwards.

This implies that, the minimum y-value is -3.

The range is y\ge-3

iii) To find the y-intercept substitute x=0 in to the function.

f(0)=|0+2|-3.

f(0)=|2|-3.

f(0)=2-3.

f(0)=-1.

The y-intercept is (0,-1)

See attachment for graph.

Explain how to use a graph of the function f(x) to<br> find f(3).
Oksanka [162]

To find the value of f(3) we need to follow the below steps :

Step 1 : First plot the graph of f(x)

Step 2 : We need to find f(3) or the function value at x = 3 therefore, in the graph locate the point (3,0)

Step 3 : Draw a line parallel to Y-axis passing through the point (3,0) .

Step 4 : Now there exists two cases :

If the drawn line do not intersect the graph of f(x), then no value of f(3) exists for the given function of x

If the drawn line intersects the graph, then the intersection point is marked and a line parallel to x - axis is drawn passing through that marked or intersection point. And the line where it intersects the y - axis is our required value of f(3).

If this is wrong than I guess I wasn't smart enough :)
