Answer:
x = 52
Step-by-step explanation:
<I = < K b/c of corresponding angles thm
x + 66 + 62 = 180
x + 128 = 180
x = 52
Answer:
D is the correct answer
Step-by-step explanation:
Not all rectangles are squares.
The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
<h3>What is the area of the circle?</h3>
The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,

Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.

Put this value in the above formula to find the area of the circle as,

Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.

<span>the particle's initial position is at t=0, x = 0 - 0 + 4 = 4m
velocity is rate of change of displacement = dx/dt = d(t^3 - 9t^2 +4)/dt
= 3t^2 - 18t
acceleration is rate of change of velocity = d(3t^2 -18t)/dt
= 6t - 18
</span><span>the particle is stationary when velocity = 0, so 3t^2 - 18t =0
</span>3t*(t - 6) = 0
t = 0 or t = 6s
acceleration = 6t - 18 = 0
t = 3s
at t = 3s, velocity = 3(3^2) -18*3 = -27m/s
displacement = 3^3 - 9*3^2 +4 = -50m
