Answer:
y is decreasing by 10units per second
Step-by-step explanation:
Given xy = 15
If x = 3
y = 15/3
y = 5
dx/dt= 6
Differentiating xy = 15 implicitly with respect to t using product rule
x
xdy/dt + ydx/dt = 0
Substitute the given value into the expression and solve for dy/dt as shown:
3dy/dt + 5(6) = 0
3dy/dt + 30 = 0
3dy/dt = -30
Divide both sides by 3
(3dy/dt )/3 = -30/3
dy/dt = -10
This means that y is decreasing by 10units per second (it is decreasing because of the negative sign)
Answer:

Answer:
13.5 minutes
Step-by-step explanation:
Cross multiply
3 × 576 = 128x
3 × 576 = 1,728
1,728 = 128x
1,728 ÷ 128 = x
13.5 = x
Answer:
119cm
Step-by-step explanation:
add 37 and 24 you get 61 and the size of a triangle no matter what is going to be 180 so then subtract 180 from 61 and get 119.
