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

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

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

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

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

Jason purchased 12 shirts for the members of a school club. Each shirt cost $5.50. Jason

Alex Ar [27]

Answer:

52 dollars and 47 cents, or 52.47

Step-by-step explanation:

First, multiply 12 and 5.50, then you should get 66.00. Then, take the 25% discount, and divide it by a hundred, you should get 0.25, now multiply 0.25 and 66.00. You should get 16.50, thats your discount, so subtract 16.50 from 66.00, you should get 49.50. Now for the sales tax, divide 6.0 by 100, you should get 0.06. Now multiply 0.06 and 49.50, you should get 2.97, thats your tax, add it to 49.50, and you get 52.47 so BOOM, thats your answer, your welcome

A linear function is parallel to the line y= 4x + 8 and also goes through the point (2,15).What is the linear equation for this

horrorfan [7]

When written in the $y=mx+q$ form, the slope of a line is given by the coefficient $m$ . Moreover, two lines are parallel if the have the same slope.

Now, the slope of the known line is 4, so our line's slope will be four as well.

In general, when you know the slope $m$ of a line and one of its points $(x_0,y_0)$ , the equation of the line can be derived from the following formula:

$y-y_0 = m(x-x_0)$

Which in your case becomes

$y-15 = 4(x-2)$

Expand the right hand side and solve for y:

$y = 4x+7$
