Answer:
Step-by-step explanation
Area of a triangle
A = ½bh
dA/dt = ½(b(dh/dt) + h(db/dt)
dA/dt = ½(4(9) + 12(-5))
dA/dt = ½(36 - 60)
dA/dt = ½(-24)
dA/dt = -12 cm²/s
Example????????????????????
Perimeter:
add all sides
(1/2)+(1/2)+(1/2)+(1/2)+1+1 = 1+1+1+1 =4cm
- initial velocity=u=0m/s
- Acceleration=a=2m/s^2
- Time=t=5s
- Final velocity=v=?
Using first equation of kinematics
Answer:
A plane has an unlimited number of points.
Step-by-step explanation:
A plane has an unlimited number of points.
An exact solution represents a point's position on the coordinate plane (x, y).
Even though a point has no dimensionality, the second assertion is incorrect.
Because a linear has only one component, length, the third assertion is likewise incorrect.
