Answer:

xy = 3

d/dt(xy) = d/dt(3)

ydx/dt + xdy/dt = 0

y = 3/x so substitute 3/5 for y, 5 for x, and 5 for dy/dt; and solve for dx/dt.

3/5(dx/dt) + 5(5) = 0

3/5(dx/dt) = -25

dx/dt = -125/3

Answer:

option D

Step-by-step explanation:

we have a right triangle

we know

c^2=a^2+b^2

c=hypotenuse

c=52 cm

a=48 cm

b= 20 cm

we  substitute in the equation c^2=a^a+b^2

so we have

52^2=48^2+20^2

52= sqrt(48^2+20^2)

52= sqrt(2304+400)

52= sqrt(2704)

52cm=52cm

so c=52 cm

so the option D is the correct answer

2 × -15 = -30

Factors of -30 that add up to -7 are -10 and 3.

Divide by 2 and reduce: -10/2 = -5/1, 3/2

The factors are x − 5 and 2x + 3.
