What is the length of the conjugate axis?<br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B%28x-2%29%5E2%7D%7B36%7D%20-%20%5Cfrac

Answer:

the length of the conjugate axis  is 16

Step-by-step explanation:

We know that the general equation of a hyperbola with transverse horizontal axis has the form:

\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} = 1

Where the point (h, k) are the coordinates of the center of the ellipse

2a is the length of the transverse horizontal axis

2b is the length of the conjugate axis

In this case the equation of the ellipse is:

\frac{(x-2)^2}{36} + \frac{(y+1)^2}{64} = 1

Then

b^2 = 64\\\\b = \sqrt{64}\\\\b = 8\\\\2b = 16

Finally the length of the conjugate axis is 16

Answer:

  D. (1.6 + 3) × (4 − 2) ÷ 2

Step-by-step explanation:

The order of operations requires that multiplication and division be done in order of appearance, left to right, before addition and subtraction. Operations in parentheses take priority.

To get 4.6, you need to add 3 to 1.6. The various forms of 3×4-2÷2 all give 12-1 = 11, not 3.

The grouping that gets it right is ...

  (1.6 + 3) × (4 − 2) ÷ 2

  = 4.6×2÷2

  = 9.2÷2

  = 4.6

nadya68 [22]
Even integers are 2 apart
they are
x,x+2,x+4

sum is
x+x+2+x+4=132
3x+6=132
minus 6 both sides
3x=126
divide both sides by 3
x=42
x+2=44
x+4=46

they are
