So, you can multiply 3(4x) to get 12x and 2(7y) to get 14y and that is it's simplest form. The answer is 12x + 14y .

The circular opening of a vase has an inside diameter of 13.5 cm.

Sunny_sXe [5.5K]

Answer:

$Area = 143cm^2$

Step-by-step explanation:

Given

Shape: Opening of a circular vase

$Diameter =13.5cm$

$\pi = 3.14$

Required

Determine the area

This opening implies a circle; hence the area will be calculated using area of a circle.

$Area = \pi r^2$

Solve for radius (r)

$r = \frac{d}{2}$

$r = \frac{13.5\ cm}{2}$

$r = 6.75\ cm$

Substitute 6.75 for r in $Area = \pi r^2$

$Area = 3.14 * 6.75^2$

$Area = 143.06625$

$Area = 143cm^2$ --- Approximated

Prove algebraically what type of function this is (even, odd, or neither).<br>f(x) = x^6 – x^4

Savatey [412]

Let's see.

We have function $f(x)=x^6-x^4$ . We have to determine if the function is even or odd or neither.

We can find this out in many ways but the assignment specifically asks to prove this algebraically.

Function is even if $f(x)=f(-x)$ , so, $x^6-x^4=(-x)^6-(-x)^4$

Which is true since negative raised to an even power is positive to that same number.

Similarly, function is odd if $f(x)=-f(-x)$ , that is,

$x^6-x^4\neq-((-x)^6-(-x)^4)$ .

So we have prooved that function $f(x)$ is an even function not an odd function and therefore also not neither.

Hope this helps.
