Answer:
4 kg of sugar would contain crystals.
Step-by-step explanation:
Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.
Thus, set up a proportion as follows:
3 kg : 9 × 10⁸ = 4 kg : x
Solve for x. Cross multiply.
Divide both sides by 3
4 kg of sugar would contain crystals.
The general form of a solution of the differential equation is already provided for us:
where . We now want to find a solution such that and . Therefore, all we need to do is find the constants and that satisfy the initial conditions. For the first condition, we have:
For the second condition, we need to find the derivative first. In this case, we have:
Therefore:
This means that we must solve the following system of equations:
If we add the equations above, we get:
If we now substitute into either of the equations in the system, we get:
This means that the solution obeying the initial conditions is:
Indeed, we can see that:
which do correspond to the desired initial conditions.

Explanation:
2 days to get this apology. its really does suck to not get your question answered in the firs ten min <span />
<span>(4 - 8i)(2 - 7i)
Use the method FOIL
8 - 28i - 16i + 56i^2
Subtract 16i from -28i
Final Answer: 8 - 44i + 56i^2</span>
