Answer:

Area of the shaded region = 75.36 in^2

Step-by-step explanation:

You find the area of the large circle and divide it in half. You find the area of the small circle and divide it in half. Finally, you subtract the small half circle from the large half circle.

A = area

π = Pi = 3.14

r = radius= the distance from the center of the circle to the edge.

A = π * r * r A = π * r * r

A = 3.14 * 8 * 8 A = 3.14 * 4 * 4

A = <u>200.96</u> A = <u>50.24</u>

2 2

A = 100.44 in^2 A = 25.12 in^2

100.44 - 25.12 = 75.36 in^2

The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.

puteri [66]

Answer:

volume = 13500 $cm^{3}$

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid = $\frac{lwh}{3}$

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume = $\frac{30*30*45}{3}$

= $\frac{40500}{3}$

= 13500

volume = 13500 $cm^{3}$

The volume of the pyramid is 13500 $cm^{3}$ .

Write out the sample space for the given experiment. Use the following letters to indicate each choice: M for mushrooms, O for o

pshichka [43]

Answer: {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}

Step-by-step explanation:

Sample space is a set that contains all the possible outcomes for an event.

For salad:

Choices for extra toppings (mushrooms, olives) =2

Choices for meats (bacon, eggs) =2

Choices for dressings (vinaigrette, honey mustard.)= 2

By Fundamental counting principal .

The number of different salads can be made= (Choices for extra toppings) x (Choices for meats ) x (Choices for dressings)

= 2 x 2 x 2 = 8

All the possible outcomes = (MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)

Required Sample space would be : {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}

The function g(n)=n²-6n+16 represents a parabola.

goblinko [34]

Part A: (n^2-6n)+16

[(n^2-6n+9)-9]+16

(n-3)^2+7

Part B: From the above result,

Vertex (3,7) this is the minimum point of the graph since the coefficient of a is positive

Part C: The axis of symmetry is basically the x coordinate of the vertex, so the axis of symmetry is x=3
