Answer: 6x^3
Step-by-step explanation:
Answer:
1/10
Step-by-step explanation:
1/2 ÷ 5
First you must use the form KCF, or Keep Change Flip
Keep the first integer (1/2)
Change the symbol (÷) > (×)
Flip the last remaining integer (5) > (1/5)
You remain with
1/2 x 1/5
Keep the numerator the same (since 1 x 1 = 1)
Multiply the denominators ( 2 x 5 = 10)
The answer is 1/10
Answer:
12...you already figured it out but alr
Step-by-step explanation:
Dy/dx = dy/dt * dt/dx
xy = 4
y + x(dy/dx) = 0 by implicit differentiation.
x(dy/dx) = -y
dy/dx = -y/x
<span>dy/dx = dy/dt * dt/dx dy/dt = -2
</span>
<span>-y/x = -2 * dt/dx
</span>
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
