8 0

If 3^(4*3) is what you mean, then here it goes:
$= 3 ^{4 \times 3} \\ = 3^{12} \\ = 531441$
If you mean (3^4)+3, then here is a different solution:
$= 3^{4} + 3 \\ = {3}^{5} \\ = 243$

B(4,5)

anyanavicka [17]

Step-by-step answer:

The general form of an equation centered at O(0,0) is given by

x^2+y^2=r^2

where r is the radius, (x,y) is any point on the circumference.

If B(4,5) lies on the circumference, then we can find the radius of the circle by substitution:

4^2+5^2=r^2

r^2 = 16+26 =41

Hence the equation of a circle centred at O(0,0) and B(4,5) on its circumference is

x^2 + y^2 = 41

A 25-foot ladder leans against a wall. The base of the ladder is 15 feet from the bottom of the wall. How far up the wall does t

Answer: 20 feet.

Step-by-step explanation:

Observe the right triangle attached.

You need to find the value of "x".

Then, you can use the Pythagorean Theorem:

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

Where "a" is the hypotenuse of the triangle, and "b" and "c" are the legs.

In this case, you can identify that:

$a=25ft\\b=15ft\\c=x$

Substitute these values into $a^2=b^2+c^2$ :

$(25ft)^2=(15ft)^2+x^2$

Now, you need to solve for x to find how far up the wall the top of the ladder reaches. Then you get:

$x^2=(25ft)^2-(15ft)^2$

$x=\sqrt{(25ft)^2-(15ft)^2}$

$x=20ft$
