Find a polynomial equation that has zeros at x = −2, x = 0, x = 3 and x = 5
VashaNatasha [74]

If a polynomial "contains", in a multiplicative sense, a factor (x-x_0), then the polynomial has a zero at x=x_0.

So, you polynomial must contain at least the following:

(x-(-2)),\quad (x-0),\quad (x-3),\quad (x-5)

If you multiply them all, you get

x(x+2)(x-3)(x-5)=x^4 - 6 x^3 - x^2 + 30 x

Now, if you want the polynomial to be zero only and exactly at the four points you've given, you can choose every polynomial that is a multiple (numerically speaking) of this one. For example, you can multiply it by 2, 3, or -14.

If you want the polynomial to be zero at least at the four points you've given, you can multiply the given polynomial by every other function.

The mass of a small virus is 10^-20 kg. The mass of an average human cell is 10^-12 kg. Which of the two has lesser mass? how ma
fredd [130]

For this case we have:

10 ^ {- 20}, we must run the decimal point 20 spaces to the left.

0.00000000000000000010 \ kg

10 ^ {- 12}, we must run the decimal point 12 spaces to the left.

0.000000000010 \ kg

Thus, it is observed that the mass of a small virus is smaller!

We subtract and obtain:

10 ^ {-11}

ANswer:

The mass of a small virus is less!
