Identify the center and radius for the equation x ^ 2 + (y - 3) ^ 2 = 4

Mathematics

marissa [1.9K]2 years ago

Answer:

r = 2.  The center is at (0, 3).

Step-by-step explanation:

Compare the given   x ^ 2 + (y - 3) ^ 2 = 4 to the standard equation

                                 (x - h)^2 + (y - k)^2 = r^2.

It becomes obvious that h = 0, k = 3 and r = 2.  The center is at (0, 3).

A wholesale club sells eggs by the dozen. Does the table show a proportional relationship between the number of dozens of eggs a
tensa zangetsu [6.8K]

Answer: The table is proportional.

Step-by-step explanation: You would do 21/6 to get 3.5. Then 28/8 to get 3.5. After 35/10 to get 3.5. Finally 49/14 to get 3.5. If each answer (3.5) is the same than it is proportional.

What does f(-1) =_<br> and x=_ ?
lubasha [3.4K]

Answer:

F(-1) = 1

x = 3

Step-by-step explanation:

1) Assume that f(-1) = y1

So that point A (x1 = -1; y1) is a point lying in the graph representing the equation y = f(x)

As it can be seen in the figure, the graph representing that equation crosses point (-1; 1)

=> Point A has y1 = 1

=> f (-1) =1

2) Assume that f(x2) = -2

So that point B (x2; y2 = -2) is a point on the graphy representing the equation y = f(x)

As indicated in the figure, the graph crosses point (3; -2)

=> Point B has x2 = 3

=> When f(x) = -2, x = 3

100 cm = 1m

To find 60 000cm, multiply by 600 :
60 000 cm = 600m                

To convert from m to km, divide by 1000 :
600m ÷ 1000 = 0.6km
