If triangle ABC was rotated 90 degrees counterclockwise about the origin, what would the ordered pairs be for B'''?
1 answer:
Answer:
Point B is
Step-by-step explanation:
Given: A triangle ABC was rotated 90 degrees counterclockwise
To find: coordinates of the point B
Solution:
A triangle is three - dimensional figure that has three sides, three vertices and three angles.
Counterclockwise refers to the direction opposite to the direction of movement of hands of the clock.
As triangle ABC was rotated 90 degrees counterclockwise about the origin, point B is

Answer:
8πcm²/sec
Step-by-step explanation:
The radius of the circle increases at a rate of dr/dt = 0.25cm/sec
The radius of the circle r = 16cm
The area of the circle increases at a rate of dA/dt = ?
Area of a circle = πr²
We take the derivative with respect to t
dA/dt = 2πrdr/dt
dA/dt = 2 π (16)(0.25)
dA/dt = 8πcm²/sec
