Answer:

$A\approx2.255 \text{ grams}$

Step-by-step explanation:

We will use the standard formula for half-life:

$\displaystyle A=A_0(a)^\frac{t}{d}$

Where A₀ is the initial amount, a is the half-life, d is the time for one half-life, and t is the number of days.

So, we will substitute 1/2 for a and 24.3 for d. This yields:

$\displaystyle A=A_0(\frac{1}{2})^\frac{t}{24.3}$

We have a 3 gram sample. Therefore, our initial amount A₀ is 3:

$\displaystyle A=(3)(\frac{1}{2})^\frac{t}{24.3}$

And we want to find the remaining sample after 10 days. So, t=10. Substitute:

$\displaystyle A=(3)(\frac{1}{2})^\frac{10}{24.3}$

Use a calculator. So:

$A\approx2.255 \text{ grams}$

Therefore, for a 3 gram sample of Phosphorous-32 with a half-life of 24.3 days, after 10 days, there will be approximately 2.255 grams remaining.

What is the product of 65(cos(14°)+ i sin(14°)) and 8(cos(4°)+ i sin(4°))

saveliy_v [14]

The product of the complex numbers 65(cos(14°)+ i sin(14°)) and 8(cos(4°)+ i sin(4°)) is 520[cos(18) + isin(18)]

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Complex number is in the form z = a + bi, where a and b are real numbers.

The product of the complex numbers 65(cos(14°)+ i sin(14°)) and 8(cos(4°)+ i sin(4°)) is:

z = 65 * 8 [cos(14 + 4) + isin(14 + 4)] = 520[cos(18) + isin(18)]
