Find dy/dx by implicit differentiation for ycos(x)=xcos(y)

alekssr [168]

Answer:

dy/dx = (cos y + y sin x) / (cos x + x sin y)

Step-by-step explanation:

y cos x = x cos y

y (-sin x) + dy/dx cos x = x (-sin y dy/dx) + cos y

-y sin x + dy/dx cos x = -x sin y dy/dx + cos y

dy/dx (cos x + x sin y) = cos y + y sin x

dy/dx = (cos y + y sin x) / (cos x + x sin y)

If you are single with no children, earn $36,000/year and set a savings goal of 5% per month, each month you should save _______

zimovet [89]

Answer:

Each month you should save $ 150

Step-by-step explanation:

First, the earnings are given per year, so we need to transform $36000/year into dollars per month. So, using a rule of three as following, we obtain:

$ 36,000 ------------- 12 months

X -------------- 1 month

Solving for X, we get:

$X=\frac{36000*1}{12}$

X = $ 3,000 /month

it means that earn $36,000/year is equivalent to earn $3,000/month

Now, we need to find the 5% of $3,000, this can be calculated making the following multiplication:

$3,000*\frac{5}{100} = 150$

Then, each month you should save $150
