The point where they intersect

horrorfan [7]2 years ago

Answer:

When it asks for where the output values are the same, it's the fancy way of saying where do the lines cross over each other. I believe it's just looking for the point of intersection. And you have it right with x = 4.

At noon, ship A is 130 km west of ship B. Ship A is sailing east at 25 km/h and ship B is sailing north at 20 km/h. How fast is

Hitman42 [59]

Answer:

answer = 12.87 km/h

Step-by-step explanation:

Given

Ship A is sailing east at 25 km/h = $\frac{dx}{dt}$

ship B is sailing north at 20 km/h = $\frac{dy}{dt}$

here x and y are the sailing at t = 4 : 00 pm for ship A and B respectively

so we get x = 4 ×25 =100 km/h

y = 4× 20 = 80 km/h

let z is the distance between the ships, we need to find $\frac{dz}{dt}$ at t = 4 hr

At noon, ship A is 130 km west of ship B (12:00 pm)

so equation will be

$z^2 = (130-x)^2 + y^2......................(i)\\put x = 100 and y = 80 \\\\we | | get \\$

$z^2 = 30^2 + 80^2\\z =\sqrt{7300} km/h$

derivative first equation w . r. to t we get

$2z\frac{dz}{dt} =$ $-2(130-x)\frac{dx}{dt}$ $+2y\frac{dy}{dt}$

$\frac{dz}{dt} =\frac{1}{z}[(x -130)\frac{dx}{dt} +y\frac{dy}{dt}]$

$\frac{dz}{dt} = \frac{( -20\times25 + 80\times20)}{\sqrt{7300} }$

$= \frac{1100}{85.44}\\ = 12.87km/h$

Jerome is a pharmacy technician that filled a prescription that use 1/4 bottle of ibuprofen. How many pills did jerome use for t

Neporo4naja [7]

It is clearly mentioned in the question that each bottle of ibuprofen has 1000 pills.

Now, 1/4 bottle of ibuprofen is used to make the prescription.

So, if one bottle of ibuprofen has 1000 pills and 1/4 1/4 bottle of ibuprofen is used to make the prescription, then Jerome obviously used $\frac{1000}{4}=250$ pills of ibuprofen to make the prescription.

This can be further explained as follows:

1 bottle=1000 pills

$\therefore \frac{1}{4}$ bottle= $\frac{1000}{4}$ =250 pills.
