Answer:

k=-1

Step-by-step explanation:

First step: Distribute

Result: -6-3k-6k=6+3k

Second step: Combine like terms

Result: -6-9k=6+3k

Third step: Add 6 to both sides

Result: -9k=12+3k

Fourth step: Subtract 3k from both sides

Result: -12k=12

Final step: Divide by -12 to both sides

Result/Answer: k=-1

[25 POINTS] The approximate change in the value of f(x) = sqrt(2(x-1)) at x = 3 using differentials with dx = 0.01 is

otez555 [7]

Answer:

$\frac{1}{200}$

Step-by-step explanation:

Find the derivative of the function when x=3

$y=\sqrt{2(x-1)}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(x-1)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(3-1)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{2(2)}}$

$\frac{dy}{dx}=\frac{1}{\sqrt{4}}$

$\frac{dy}{dx}=\frac{1}{2}$

Since the change in the value of the function is $dy$ and we know that the change in x is $dx=0.01$ , then we have:

$\frac{dy}{dx}=\frac{1}{2}$

$dy=\frac{1}{2}dx$

$dy=\frac{1}{2}(0.01)$

$dy=\frac{1}{200}$

Therefore, the 2nd option is correct

1. Find the compound interest and maturity value if P = P43,000, with a rate of 5% is compounded semi-annually for 6 years.

Leno4ka [110]

The Answer is that the present value of $100 is $100. Because this $100 dollar is deposited today so the time is equal to zero and when time is zero the value of amount is the value of amount itself.
