<span>For given hyperbola:
center: (0,0)
a=7 (distance from center to vertices)
a^2=49
c=9 (distance from center to vertices)
c^2=81
c^2=a^2+b^2
b^2=c^2-a^2=81-49=32
Equation of given hyperbola:


..
2: vertices (0,+/-3) foci (0,+/-6)
hyperbola has a vertical transverse axis
Its standard form of equation:  , (h,k)=(x,y) coordinates of center
For given hyperbola:
center: (0,0)
a=3 (distance from center to vertices)
a^2=9
c=6 (distance from center to vertices)
c^2=36 a^2+b^2
b^2=c^2-a^2=36-9=25
Equation of given hyperbola:

Somebody please help!!!!!!!!
Jlenok [28]

Answer:

I think the answer is b^2=8^2-4^2

Step-by-step explanation:

The equation is A^2+B^2=C^2

C^2-A^2=B^2

C^2-B^2=A^2

C is the hypotenuse. You know what a is and all you have to do is show the equation

The diagram below shows an Isosceles triangle. Label the base angles and the vertex
Anna007 [38]

The  measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

Find the diagram attached.

The base of the isosceles triangle is "b".

Since the base angles are equal, hence the sum of the interior angle is expressed as:

b + b + 112  = 180

2b + 112  = 180

2b = 180 - 112

2b = 68

b = 68/2

b = 34 degrees

Hence the  measure of each base angle is 34 degrees and the measure of the vertex angle is 112 degrees

Let ​ x^2+18x=44 .​ What values make an equivalent number sentence after completing the square?
Lostsunrise [7]
To find the final term to compete the square you need to divide the 'x' term by 2 then square it

x^2 +18x + = 44+ \\ x^2+18x+( \frac{18}{2} )^2=44+( \frac{18}{2} )^2 \\ x^2+18x+9^2=44+9^2 \\ x^2+18x+81=44+81 \\ (x+9)^2=125 - equivalent equation
