A 90-day simple interest loan in the amount of $2,350 will be paid in full in the amount of $2,500.
puteri [66]

Answer:

  26%

Step-by-step explanation:

The amount due is ...

  A = P(1 +rt)

  2500 = 2350(1 +r(90/360)) . . . . using ordinary interest

  2500/2350 -1 = r/4

  r = 12/47 ≈ 25.53% ≈ 26%

The rate of the loan is about 26%.

One shape is approaching a poor from the east traveling west at 15 mph and its presently 3 miles east east of the port I second
valentinak56 [21]

Answer:

DL/dt = 17 mph

Step-by-step explanation:

The ships and the port shape a right triangle

Ship  going west ( x-direction)   is traveling at 15 mph

Ship going north  (y-direction) is traveling at 10 mph

The distance L between ships is:

L²  = x² + y²

Tacking derivatives on both sides of the equation with respect to time

we get

2*L*DL/dt = 2*x*Dx/dt  + 2*y*Dy/dt    (1)

In that equation we know:

Dx/dt  = 15 mph

Dy/dt  = 10 mph

At the moment  ship traveling from the east is at 3 miles from the port

then x = 3 m  and the other ship is at 4 miles north

then by Pythagoras theorem

L = √ 3² + 4²    L = 5

By substitution in equation 1

2*5*DL/dt  = 2*3*15 + 2*4*10

10* DL/dt  =  90  +  80

DL/dt = 170 / 10

DL/dt = 17 mph
