Solve for a and b in the graphed hyperbola

Answers

Answer 1

Answer:

ANSWER

a=1 and b=-12

EXPLANATION

The hyperbola has a hole at:

x=3

and a vertical asymptote at x=-4.

This implies that the denominator of the rational function is

(x-3)(x+4)

We expand to get;

${x}^(2) + 4x - 3x - 12$

This simplifies to:

${x}^(2) + x - 12$

comparing to

${x}^(2) + ax + b$

We have a=1 and b=-12

D. reflection across the y-axis

Which is what the length of the hypotenuse of the triangle ?

Answers

For this, you will be doing the pythagorean theorem, which is $leg^2+leg^2=hypotenuse^2$ . In this case, the legs are 12 and 35 and the hypotenuse is AB. Using this, the equation will look like this:

$12^2+35^2=AB^2$

Firstly, solve the exponents: $144+1225=AB^2$

Next, add up 144 and 1225: $1369=AB^2$

Lastly, square root each side, and your answer should be $37 = AB$

In short, the hypotenuse is 37 ft, or the last option.

THE ANSWER IS D ON EDGEN.

D. 37 ft.

What is 9 6/9 - 4 8/9

Answers

The answer is 4 7/9.

Since you cannot subtract the numerators, you have to take 1 from the whole number, so 9 turns into 8 and you add the denominator to the numerator to make the equation 8 15/9 - 4 8/9 which is 4 7/9 :).

You already have a common denominator, so you should convert to improper fractions to subtract them easier. These would be 87/9-44/9, and then you subtract the numerators and leave the denominator. 87-44=43, so your answer is 43/9, or 4 7/9, or 4.77777...
