By definition, we have the following logarithm properties:

$log (A * B) = log (A) + log (B)\\log (A ^ n) = n * log (A)\\log (\sqrt [n] {A}) = \frac {1} {n} * log (A)$

Now, we can rewrite the given expression as:

$log_ {5} [((5x ^ 3) ^ 2) * \sqrt [3] {x ^ 2 + 6}] =\\log_ {5} (5x ^ 6 * \sqrt [3] {x ^ 2 + 6})$

The t value for a 99% confidence interval estimation based upon a sample of size 10 is

Aliun [14]

Answer:
For a sample size of 10, the t-value is about 3.25 (from tables) at a 99% confidence interval.

Explanation:
When the standard deviation for the population is not known, the confidence interval estimate for the population mean is performed with the Student's t-distribution.
The confidence interval for the mean is calculated as
$(\Bar{x}- t\frac{s}{\sqrt{n}} , \, \Bar{x}+ t\frac{s}{\sqrt{n}}$
where
$\Bar{x}$ = sample mean,
s = sample standard deviation,
t = t-value (provided in tables),
n = sample size.

When reading the t-value, (n-1) is called the df or degrees of freedom.

A certain dodgeball court is a circle with a square perfectly inscribed inside it. the square represents the playing field, whil

cluponka [151]

<span>Exactly 8*pi - 16
Approximately 9.132741229 For this problem, we need to subtract the area of the square from the area of the circle. In order to get the area of the circle, we need to calculate its radius, which will be half of its diameter. And the diameter will be the length of the diagonal for the square. And since the area of the square is 16, that means that each side has a length of 4. And the Pythagorean theorem will allow us to easily calculate the diagonal. So: sqrt(4^2 + 4^2) = sqrt(16 + 16) = sqrt(32) = 4*sqrt(2) Therefore the radius of the circle is 2*sqrt(2). And the area of the circle is pi*r^2 = pi*(2*sqrt(2)) = pi*8 So the area of the rest areas is exactly 8*pi - 16, or approximately 9.132741229</span>

Can you guys check these :) I’ll give brainleist :)

Answer:

9. No

10. Yes

Step-by-step explanation:

The first one is not, since you have (3, 3) and (3, 9). In a function, each x maps to a single y.

The second one is since every x appears only once.
