The equation of a hyperbola is shown. (x-3)^2/81-y^2/144=1
What are the coordinate of the center of the hyperbola?
A.) (3,0)
B.) (0,-30)
C.) (0,3)
D.) (-3,0)

Answers

Answer 1
Answer: for equatin (x-h)^2/a^2 - (y-k)^2/b^2 =1 center will be (h,k)
in our problem h=3, k= 0
so center is (3,0)

Answer:

Basic Formulas

sin θ = Opposite Side/Hypotenuse.

cos θ = Adjacent Side/Hypotenuse.

tan θ = Opposite Side/Adjacent Side.

sec θ = Hypotenuse/Adjacent Side.

cosec θ = Hypotenuse/Opposite Side.

cot θ = Adjacent Side/Opposite side.

What is the solution of the equation? eliminate any extraneous solutions. (−2x + 6)15= (−8 + 10x)15?

Answers

Divide both sides by 15:  -2x +6 = -8 + 10x
Add 2x to both sides:               6 = -8 + 12x
Add 8 to both sides:                14 = 12x
Divide both sides by 12:          14/12 = x
Reduce the fraction:                  7/6 = x

Answer: x = 7/6

The formula to find the cost c of a square sheet of a glass is c=25s2 where a represents the length of a side in feet. how much will ricardo pay for a square sheet of glass that is 3 feet on each side

Answers

To calculate the cost of Ricardo, we just have to substitute the measurement of the length he wants to the function of the cost given. We do as follows:

c = 25s^2
c = 25(3)^2
c = 225

Therefore, the cost would be 225.

What is answer to x+10=-13  what does x equal

Answers

x + 10 = -13
-13 - 10 = x
-23 = x

CHECK

-23 + 10 = -13
-13 = -13!
x + 10 = -13 (original problem)
   -10      -10 (subtract 10 from each side)
The 10 - 10 equals 0 so it cancels out of the problem.
x = -23  <- (-13 - 10 = -23)
