Answer:

Option 2nd is correct

$9^x-3 =9^3$

Step-by-step explanation:

Given the equation:

$9^x-3 = 729$

We can write 729 as

$729 = 9 \cdot 9 \cdot 9 = 9^3$

then;

$9^x-3 =9^3$

Therefore, the equation which is equivalent to $9^x-3 = 729$ is, $9^x-3 =9^3$

Use algebraic methods to prove that the given function has an x-intercept that is equal to its y-intercept. In your final answer

Llana [10]

Given the function, y = x/( x^2 – 1)

Add x and subtract x from (x^2 – 1) to make it a complete square

y = x/(x^2 + x – x – 1)

y = x/[x(x + 1) – 1(x + 1)]

y = x/[(x – 1)(x + 1)]

In order to find the y -intercept, we set x = 0

When x = 0

y = 0/[(0 – 1)(0 + 1)]

y = 0.

Therefore, the y-intercept is zero.

In order to find the x -intercept, we set y = 0

When y = 0

0 = x/[(x – 1)(x + 1)]

The only way the product of a division will be zero is if the numerator is zero

So, if x/[(x – 1)(x + 1)] = 0

x = 0

Therefore, the x-intercept is also zero.

Since both x- intercept and y- intercept equal zero,

Then, the given function has an x-intercept that is equal to its y-intercept

The volume of the above solid is?

svet-max [94.6K]

The solid in the picture is a cylinder; thus, we can use the following formula:

$V=\pi*r^2h$

This formula works even if the solid is slanted.
The radius is 6 cm and the height is 5 cm.
$r=6$
$h=5$

Plug in these values into the volume formula.

$V=\pi*r^2h$

$=\pi*6^2*5=\pi*36*5=180 \pi$

The volume is 180π cm³. I hope this helps! :)
