Answer:

3.63E-5

Step-by-step explanation:

Convert 3.63 x 10^-5 from a scientific calculator

We do this by raising 10^n power * whole number entered where n=-5

3.63 x 10^-5 converted to a number = 3.63 x 1.0E-5

3.63 x 1.0E-5 converted to a number = 3.63E-5

Which 2 values of x are roots of the polynomial below?

Alexxx [7]

Given:

The given polynomial is:

$f(x)=$ $3x^{2}-3x+1$

To find the roots of the given polynomial.

To find the roots we have to take $f(x) = 0$

So,

$3x^{2} -3x+1 = 0$

Formula

By quadratic formula, the root of the equation $ax^{2} +bx+c = 0$ is,

$x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}$ and $\frac{-b-\sqrt{b^{2} -4ac} }{2a}$

Now,

Putting, $a=3, b=-3, c=1$ we get,

$x = \frac{3+\sqrt{3^{2}-4(3)(1) } }{(2)(3)}$ and $\frac{3-\sqrt{3^{2}-4(3)(1) } }{(2)(3)}$

$x = \frac{3+\sqrt{-3} }{6}$ and $x=\frac{3-\sqrt{-3} }{6}$

Hence,

The values of the roots of the given polynomial are $x=\frac{3+\sqrt{-3} }{6}$ and $x=\frac{3-\sqrt{-3} }{6}$

Hence, Option A and F are the correct answer.

Please help me divide

saul85 [17]

leg^2 + leg^2 = hyp^2

5^2 + 12^2 = hyp^2

25 + 144 = hyp^2

169 = hyp^2

13 = hyp

Hope this helps! ;)

A rectangular field is 36

blagie [28]

Answer:

12meters

Step-by-step explanation:

Given data

Lenght = 36 meters

Width = 15 meters

The dimension of the diagonal can be gotten via Pythagoras theorem

D^2= L^2+W^2

Substitute

D^2= 36^2+ 15^2

D^2= 1296+225

D^2= 1521

D= √1521

D= 39 meters

Hence the distance while walking on the side is

=36+15

=51 meters

Hence the difference is

=51-39

=12meters
