Let u=ln x and v= ln y. Write ln(square root x times y^2)

1 answer:

6 0

0.5u + 2v. This is because u can separate the logs to ln(sqrx) + ln(y^2) and use basic log principles to get 0.5lnx +2lny. Then u substitute

A new computer can complete a complex biochemistry calculation in 11 hours less than an older-model computer. Working together,

AlekseyPX

Answer:

New computer will take 33.28 hours to complete the calculation by itself.

Step-by-step explanation:

Let the time taken by the new computer to complete the calculation = x hours

Per hours work done by the new computer = $\frac{1}{x}$

Time taken by the older computer to complete the calculation = (x + 11) hour

Per hour work done by old computer = $\frac{1}{(x+11)}$

When both the computers work together they complete the work in 19 hours.

Therefore, per hour work done by both together = $\frac{1}{19}$

We per hour work done by both individually = per hour work done by both together

$\frac{1}{x}+\frac{1}{x+11}=\frac{1}{19}$

$\frac{x+x+11}{x(x+11)}=\frac{1}{19}$

$\frac{2x+11}{x(x+11)}=\frac{1}{19}$

38x + 209 = x² + 11x

x² - 27x - 209 = 0

By quadratic formula,

x = $\frac{27\pm \sqrt{(-27)^{2}-4\times 1\times (-209)}}{2}$

x = $\frac{27\pm \sqrt{729+836}}{2}$

x = $\frac{27\pm \sqrt{1565}}{2}$

x = $\frac{27\pm 39.56}{2}$

x = 33.28 hours

Therefore, new computer will take 33.28 hours to complete the calculation by itself.

Frodo made a down payment of $4,800 toward the purchase of a new ring. To pay the balance of the purchase price, he has secured

Brrunno [24]

The cash price of the ring was $ 16,560.80.

Knowing the down payment, the interest rate and the monthly payments, to determine what is the cash price of the ring, the following calculation must be performed, applying the compound interest formula:

Initial value x (1 + interest rate / compounding times) ^ (years x compounding times) = Compound interest
X x (1 + 0.072 / 12) ^ 3.5x12 = 360 x 42
X x 1.006 ^ 42 = 15,120
X x 1.2856 = 15,120
X = 15,120 / 1.2856
X = 11,760.80
11,760.80 + 4,800 = Cash price
16,560.80 = Cash price

Therefore, the cash price of the ring was $ 16,560.80.
