A doctor takes a sample of Laura's blood. There are 4.5 x 10 To the sixth power red blood cells and 5000 white blood cells. How

VikaD [51]

Answer:

900 times

Step-by-step explanation:

A doctor takes a sample of Laura's blood. There are $4.5 \times 10^{6}$ red blood cells and 5000 white blood cells.

Now, we are asked to get how many times more red blood cells are there than white blood cells in the sample.

There were $4.5 \times 10^{6}$ = 4500000 red blood cells in the sample.

Hence, $\frac{4500000}{5000} = 900$

And there are 900 times more red blood cells than white blood cells in the sample. (Answer)

Find the estimates of x^2-x-2=3

Julli [10]

Answer:

$x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79$

Step-by-step explanation:

Given

Quadratic equation is

$x^2-x-2=3\\x^2-x-5=0$

Roots of the quadratic equation $ax^2+bx+c=0$ are

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

So, for the given equation roots are

$x=\frac{1\pm\sqrt{(-1)^2-4(1)(-5)}}{2\cdot 1}\\x=\frac{1\pm\sqrt{21}}{2}\\so, x=\frac{1+\sqrt{21}}{2}\approx 2.79\\or\ x=\frac{1-\sqrt{21}}{2}\approx -1.79$
