Answer:

64 (if 4 x 4 x 4) or

12 (it could be any of them)

Step-by-step explanation:

Since "3" is related to l x w x h.

You can either do 4 x 4 x 4

4 x 3

It depends what formula (aka L x W x H).

What is the surface area of a sphere with radius 2

Gelneren [198K]

Answer:

Step-by-step explanation:

The surface area (A) of a sphere is calculated as

A = 4πr² ← r is the radius

here r = 2, hence

A = 4π × 2² = 4π × 4 = 16π units² → A

There exist two complex numbers $c$, say $c_1$ and $c_2$, so that $3 + 2i$, $6 + i$, and $c$ form the vertices of an equilateral

leva [86]

Answer:

The answer is " $\sqrt{12.5}$ "

Step-by-step explanation:

$\to (3,2), \ (6,1)$

Distance $=\sqrt{9+1}=\sqrt{10}$

midpoint height $=\sqrt{10+2.5}=\sqrt{12.5}$

let

Gradient $= \frac{1}{-3}$

Perpendicular Gradient $= 3$

midpoints $= (4.5, 1.5)$

Similar to perpendicular

Now I'll obtain the perpendicular bisector solution

An equation of the center circle $(4.5,1.5)$ radius will be $\sqrt{12.5}$ .

Write two different rational functions whose graphs have the same end behaviour as the graph of y=3x^2

baherus [9]

Answer:

$y=x^2+5x+20\\ \\ y=8x^2+35$

Explanation:

The <em>end behavior</em> of a <em>rational function</em> is the limit of the function as x approaches negative infinity and infinity.

Note that the the values of even functions are the same for ± x. That implies that their limits for ± ∞ are equal.

The limits of the quadratic function of general form $y=ax^2+bx+c$ as x approaches negative infinity or infinity, when $a$ is positive, are infinity.

That is because as the absolute value of x gets bigger y becomes bigger too.

In mathematical symbols, that is:

$\lim_{x \to -\infty}3x^2=\infty\\ \\ \lim_{x \to \infty}3x^2=\infty$

Hence, the graphs of any quadratic function with positive coefficient of the quadratic term will have the same end behavior as the graph of y = 3x².

Two examples are:

$y=x^2+5x+20\\ \\ y=8x^2+35$
