5 0

Answer:

The answer is "\frac{x^2}{9}-\frac{y^2}{64} =1"

Step-by-step explanation:

In the given question some information is missing that is value.

Given value:

\frac{x^2}{3^2} - \frac{y^2}{8^2} =1

The formula of hyperbola is:

\Rightarrow \frac{x^2}{h^2} - \frac{y^2}{k^2} = 1\\\\

\Rightarrow \frac{x^2}{3^2} - \frac{y^2}{8^2} =1\\\\\Rightarrow \frac{x^2}{9} - \frac{y^2}{64} =1\\\\

Find two numbers whose sum is 25 and the sum of whose reciprocals is 1/6
Katen [24]

Answer:

10 and 15

Step-by-step explanation:

Let 'x' and 'y' are the numbers we need to find.

x + y = 25 (two numbers whose sum is 25)

(1/x) + (1/y) = 1/6 (the sum of whose reciprocals is 1/6)

The solutions of the this system of equations are the numbers we need to find.

x = 25 - y

1/(25 - y) + 1/y = 1/6 multiply both sides by 6(25-y)y

6y + 6(25-y) = (25-y)y

6y + 150 - 6y = 25y - (y^2)

y^2 - 25y + 150 = 0 quadratic equation has 2 solutions

y1 = 15

y2 = 10

Thus we have :

First solution: for y = 15, x = 25 - 15 = 10

Second solution: for y = 10, x = 25 - 10 = 15

The first and the second solution are in fact the same one solution we are looking for: the two numbers are 10 and 15 (since the combination 10 and 15 is the same as 15 and 10).

Find the value of each variable. Write the<br> equation and solve showing ALL the work.
Wittaler [7]

Answer:

x = 96°

y = 102°

Step-by-step explanation:

Angles on a straight line add up to 180

78 + y = 180

y = 180 - 78

y = 102

Angles in a quadrilateral add up to 360

78 + 90 + x + x = 360

78 + 90 + 2x = 360

168 + 2x = 360

2x = 360 - 168

2x = 192

x = 192/2

x = 96°
