Name this polynomial by its degree: 3x² + 5x-3
Stella [2.4K]

Answer:

\boxed{\textsf {The given polynomial is a quadratic polynomial. }}

Step-by-step explanation:

A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .

\sf\implies p(x)= 3x^2+5x-3

So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .

<u>★</u><u> </u><u>More </u><u>to </u><u>Know </u><u>:</u><u>-</u>

When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.

That is ,

\sf\implies p(x)= 3x^2+5x-3=0

This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .

Find the diameter of the sphere with the volume of 36 pi cubic units
kobusy [5.1K]

Answer:

{ \tt{volume =  \frac{4}{3} \pi {r}^{3} }} \\ 36\pi =  \frac{4}{3} \pi \times  {(2d)}^{3}  \\  \frac{36 \times 3}{4}  = 8 {d}^{3}  \\ 27 = 8 {d}^{3}  \\  {d}^{3}  =  \frac{27}{8}  \\ diameter = 1.5 \: units
