Answer:

The number is 5

Step-by-step explanation:

6+3n = 5n-4

Subtract 3n from each side

6+3n-3n = 5n-3n-4

6 = 2n-4

Add 4 to each side

6+4 = 2n-4+4

10= 2n

Divide by 2

10/2 =2n/2

5=n

Suppose xy=4 and dy/dt=-2. Find dx/dt when x=-3

nirvana33 [79]

Dy/dx = dy/dt * dt/dx

xy = 4

y + x(dy/dx) = 0 by implicit differentiation.

x(dy/dx) = -y

dy/dx = -y/x

dy/dx = dy/dt * dt/dx dy/dt = -2

-y/x = -2 * dt/dx

y/(2x) = dt/dx

dt/dx = y/(2x)

dx/dt = 2x/y

When x = -3, xy = 4, y = 4/x = 4/-3 = -4/3

dx/dt = 2*-3/(-4/3) = -6 *-3/4 = 18/4 = 9/2 = 4.5

dx/dt = 4.5

(0, 0) → t = 0, w = 0 → w = 0 · 0

(1, 4) → t = 1, w = 4 → w = 1 · 4

(2, 8) → t = 2, w = 8 → w = 2 · 4

(3, 12) → t = 3, w = 12 → w = 3 · 4

<h3>Answer: w = 4t</h3>

The diagonals of a square are 4 meters long. The side of this square is equal to the diagonal of a second square. Find the side

jok3333 [9.3K]

Check the picture below.

since the second figure is also a square, then the sides touching the diagonals have to be all equal, and that'd only happen if those sides bisects the larger square's diagonal.
