452.16 because pie is 3.14 and the formula for area is pie x radius squared and radius here is 12 so 3.14x12^2 is 452.16

What are the potential solutions of In(x^2-25)=0?

Maslowich

Answer:

$x =\pm \sqrt{26}$

Step-by-step explanation:

Given :-

ln ( x² - 25 ) = 0

And we need to find the potential solutions of it. The given equation is the logarithm of x² - 25 to the base e . e is Euler's Number here. So it can be written as ,

Equation :-

$\implies log_e {(x^2-25)}= 0$

In general :-

If we have a logarithmic equation as ,

$\implies log_a b = c$

Then this can be written as ,

$\implies a^c = b$

In a similar way we can write the given equation as ,

$\implies e^0 = x^2 - 25$

Now also we know that $a^0 = 1$ Therefore , the equation becomes ,

$\implies 1 = x^2 - 25 \\\\\implies x^2 = 25 + 1 \\\\\implies x^2 = 26 \\\\\implies x =\sqrt{26} \\\\\implies x = \pm \sqrt{ 26}$

Hence the Solution of the given equation is ±√26.

Find the perimeter and round your answer to the nearest tenths. Can anyone help me with this? I cannot find any videos or exampl

liberstina [14]

Answer:

22.8

Step-by-step explanation:

the rectangular has :

the length CD =√[(3+3)²+(0-5)²]

= √(36+25) = √61 = 7.8

the width BC =√[(5-3)²+(3-0)²]

=√(4+9 =√13 = 3.6

so, the perimeter = 2(7.8 + 3.6)

= 2× 11.4 = 22.8

Think of F(x) is y so the domain would be the opposite side so the answer would be the X side so F -4 -1 0 2 and 7
