Look at this it explains how to solve it.
Answer:
1.26 m^2 / s.
Step-by-step explanation:
The area A of the triangle = 1/2*7*12 sin x = 42 sin x where x is the angle between the lines.
Relation between the rates is
dA/dt + dA/dx * dx/dt
We are given that dx /dt = 0.06 rad/s.
A = 42 sin x
dA/dx = 42 cos x
So dA/dt = 42 cos x * 0.06
When x = π/3 ( I am assuming that π 3 means π divided by 3 ):
dA/dt = 42 cos π/3 * 0.06
= 1.26 m^2/s.
Answer:
C (- 4, - 2 )
Step-by-step explanation:
(c)
the x- coordinate of A is - 4
the y- coordinate of B is - 2
coordinates of C = (- 4, - 2 )
Answer:
G. 4 x (-5)
Step-by-step explanation:
This gets you to -20 and you are subtracting 5 4 times. So this makes the most sense to me.
Hope it helps!
With this question, you are just going to add up the three numbers
1,300 + 1,400 + 1,500
This equals 2,200
Hope I helped!
