Mathematics

Answer:

dy/dt=2

Step-by-step explanation:

y=√x

dy/dx=1/(2√x)

when x=9

dy/dx=1/(2√9)=1/(2×3)=1/6

dy/dx=(dy/dt)/(dx/dt)

1/6=(dy/dt)/12

dy/dt=1/6×12=2

A toy factory assembles 19,824 toy castles over a 12 hour period time. The same number of castle is assembled each hour?
Leya [2.2K]
So you would form a proportion 12/19824=1/x then you would cross multiply 12x= 19824 next you would isolate the variable by using inverse operations 19824 divided by 12 = 1652 toy castles

Can you please help me i’ll give extra points
Sauron [17]

First, we need to solve for sin(67°) = 22/x. Multiply each side by x and divide each side by sin(67°)

x = 22/sin(67°) = 23.9

Use pythagorean theorem to find the last side.

a^2 + 22^2 = 23.9^2

a^2 + 484 = 571.21. Subtract each side by 484

a^2= 87.21. Take the square root of each side.

a = 9.3

x = 23.9 and the other side is 9.3
