Answer:
when we multiply a number by its reciprocal we get-
For example- 2/1 × 1/2 = 1 . Every number has a reciprocal except 0 (1/0 is undefined)
The answer to your question should be b
Answer:
50.24 sq. units
Step-by-step explanation:
S = 4πr² = 4×3.14× 2² = 3.14 × 16 = 50.24 sq. units
Answer:
-3-4x
Step-by-step explanation:
Given that the hyperbola has a center at (0,0), and its vertices and foci are on y-axis. This, the equation of the hyperbola is of the form
x²/a²-y²/b²=-1 (a>0, b>0)
In the equation, vertices are (0, +/-b) .
Thus,
b=60
Foci (0,+/-√(a²+b²))
thus
√(a²+60²)=65
hence solving for a²
a²=65²-60²
a²=625
a²=25²
hence the equation is:
x²/25²-y²/60²=-1
