Answer:

Yes, the sides form a right triangle.

Step-by-step explanation:

<u>Pythagorean Theorem:</u>

a² + b² = c²

↓

20² + 21² = 29²

║a² = 20² = 400

║b² = 21² = 441

║c² = 29² = 841

↓

400 + 441 = 841

║This equation is true.

↓

Yes, the sides form a right triangle.

Determine the vertical asymptotes for the reciprocal of this function f(x)=x^2 + 3x -28
Gennadij [26K]

Answer:

x = -7 and x = 4.

Step-by-step explanation:

f(x) = x^2 + 3x - 28

= (x + 7)(x - 4).

The reciprocal of f(x) can be written as

1 / (x + 7)(x - 4).

When the denominator is zero we have vertical asymptotes

so they are x = -7 and x = 4.
