C. 3

The shape can fit on to itself 3 times before returning to its original position.

Next time try this:

1. Trace and cut out the shape
2. Label the top 'A'
3. Trace the shape one more time. DO NOT CUT THIS ONE OUT
4. Put the cut out shape on the 2nd traced one
5. Put a pen in on the point, like a spinner, and rotate it 90degrees
6. See how many it can fit into itself before 'A' returns to the top.

That will be your answer.

An ellipse has a vertex at (14, –1). The focus of the ellipse nearest that vertex is located at (8, –1). If the center of the el
zavuch27 [327]
Refer to the diagram shown below.

The right vertex is at (14, -1), and the center is at (-1, -1).
Therefore the semi-major axis is
a = 14 - (-1) = 15

The right focus is at (8, -1).
Therefore
c = 8 - (-1) = 9.

The distance of the directrix from the center is
d = c²/a = 9²/15 = 81/15 = 27/5.

Therefore the equation for the left directrix is
x = -1 - 27/5 = -32/5

Answer: x = -27/5

E varies directly with the square root of C. If E=40 when C=25 find: E when C= 49
tiny-mole [99]

Answer: E = 56

Step-by-step explanation:

E is proportional to √C

To remove proportionality, introduce a constant (k).

E = k × √C

From question,

E = 40 and C = 25

So,

40 = k ×√25

40 = k × 5

k = 8

Now,

C = 49

k = 8

E = ?

E = k√C

E = 8 × √49

E = 8 × 7

E = 56
