Pie

Answer:

D. $= \frac{b}{a}$

Step-by-step explanation:

Given:

$\frac{b^{-2}}{ab^{-3}}$

Required:

Assuming a ≠ 0, b ≠ 0, find the expression equivalent to the given expression.

SOLUTION:

$\frac{b^{-2}}{ab^{-3}}$

Recall the exponent rule => $\frac{x^{a}}{x^{b}} = x^{a - b}$

Applying the exponent rule, we would have:

$\frac{b^{-2 -(-3)}}{a}$

$= \frac{b^{-2 + 3}}{a}$

$= \frac{b^{1}}{a}$

$= \frac{b}{a}$

Thus, the equivalent expression of $\frac{b^{-2}}{ab^{-3}}$ = $\frac{b}{a}$

answer:

(a).

Equation of circle is x² + y² - 25 = 0

(b).

(-5, 0) » yes

(√7, 1) » no

(-3, √21) » no

(0, 7) » no

Step-by-step explanation:

(a).

If centred at origin, centre is (0, 0)

General equation of circle:

${ \boxed{ \bf{ {x}^{2} + {y}^{2} + 2gx + 2fy + c = 0}}}$

but g and f are 0:

${x}^{2} + {y}^{2} + c = 0 \\ but : \\ c = {g}^{2} + {f}^{2} - {r}^{2} \\ c = { - 25}$
