Answer:
I don't understand can you explain it differently?
a. When v = c, then v^2 = c^2. The fraction v^2/c^2 becomes 1. The inside of the root is 1 - 1 which equals zero. Square root of zero is zero, and zero times L0, no matter what value L0 has, is zero. Therefore, when v = c, the left side equals zero.
b. When v = 0, and c is positive, v/c = v^2/c^2 = 0. By subtracting v^2/c^2, which is zero for v = 0, from 1, you get 1. Square root of 1 is 1. Then you multiply that by L0 to get L0. The greatest possible value of the left expression is L0.

Answer:
62.8 ft²
Step-by-step explanation:
The area (A) of the sector is calculated using the formula
A = area of circle × fraction of circle
= π × 4² ×
= π × 16 ×
= π × 20 = 20π ≈ 62.8 ft²
25. <u>Step-by-step explanation:</u>
To find the foci, first we must find the length of the foci using the formula:
Then add the c-value to the h (or k)-value that represents the major.
b² - a² = c²
25 - 16 = c²
9 = c²
±3 = c
The center is (0, 0) and the major is the y-value so the foci is:
(0, 0+3) and (0, 0-3) ⇒ (0, 3) and (0, -3)
26. Answers
Follow the same steps as #25:
Center: (0, 0)
Vertices (7, 0) and (-7, 0)
Co-vertices: (0, 3) and (0, -3)
foci: (2√10, 0) and (-2√10, 0)
length of major: 14
length of minor: 6
