IRISSAK [1]

Answer:

-43

Step-b-y-step explanation:

f(x)= -x^2+7x-13 so

f(-3)= - (-3)^2 + 7(-3) - 13

= -9 - 21 - 13

= -43.

Answer:

The required equation is $b=\sqrt{c^2-a^2}$

Step-by-step explanation:

Consider the provided equation.

$c= \sqrt{a^{2}+b^{2}}$

Solve the equation for b.

Square both the sides.

$c^2= a^{2}+b^{2}$

Subtract a² from both the sides.

$c^2-a^2= b^{2}$

Square root both the sides.

$b=\sqrt{c^2-a^2}$

Hence the required equation is $b=\sqrt{c^2-a^2}$
