Use the quadratic formula to find the solutions to the

nadezda [96]

Answer:

Step-by-step explanation:

The quadratic formula:

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

where a is the coefficient of $x^2$ , b being the coefficient of $x$ and c being the constant.

Plug in the values:

$\frac{-\left(-5\right)\pm \sqrt{\left(-5\right)^2-4\cdot \:2\cdot \:5}}{2\cdot \:2}$

$\frac{5\pm\sqrt{-15} }{4}$

Since $\sqrt{-15} =\sqrt{-1} \sqrt{15} =i \sqrt{15}$

The answer is:

$\frac{5\pm i \sqrt{15} }{4}$

A geologist in South America discovers a bird skeleton that contains 80% of its original amount of C-14

We use formula $N = N_oe^{-kt}$

N0= initial amont of C-14 (at time t=0)

N= amount of C-14 at time t

t= time, in years

k= 0.0001

N is 80% of N0 that is $N= 0.80N_o$

$N = N_oe^{-kt}$

$0.80N_o = N_oe^{-kt}$

Divide both sides by N_o

$0.8=e^{-0.0001 t}$

Take ln on both sides

$ln(0.8)=lne^{-0.0001 t}$

ln(0.8) = -0.0001t ln(e)

ln(0.8) = -0.0001t

Divide both sides by -0.001

t = 2231.435513

The age of the bird skeleton is 2231 years old

I thought of a two-digit number. The unit digit of my number is a prime number, and the tens digit is four times as big as the u

denis-greek [22]

let the number is 10x + 3.

then sum of its digits = x + 3.

from given condition, we have

x+3 = (1/7)* (10x + 3)

=> 7x + 21 = 10x + 3

=> 3x = 18

=> x = 6

therefore the number is 63.
