Answer:
49.132 m²
Step-by-step explanation:
Area of a triangle=1/2(base×height)
Area=1/2(6×8)
Area=24 m²
Now
Area of semi circle=πr²/2
Area=(3.14)(8÷2)²/2
Area=(3.14)(4)²/2
Area=(3.14)(16)/2
Area=50.265/2
Area=25.132 m²
Now
Total area=area of triangle+semi-circle
Total area=24+25.132
Total area=49.132 m²

Answer:
A. 3 < t < 9
Step-by-step explanation:
When the particle is moving to the right, the velocity is positive.
To find the velocity, take the derivative of s(t) with respect to t.
s(t) = -t³/3 + 13t²/2 − 30t
s'(t) = -t² + 13t − 30
Find when the velocity is 0.
0 = -t² + 13t − 30
0 = t² − 13t + 30
0 = (t − 3) (t − 10)
t = 3, 10
Check the sign of s'(t) in each interval.
0 < t < 3, s'(t) < 0
3 < t < 9, s'(t) > 0
The particle moves to the right when 3 < t < 9.

Answer: Choice D. (3p, 3p+4) </h3>
=============================================
Work Shown:
f(x) = x+4
y = x+4 ..... since y = f(x)
y = 3p+4 .... replace x with 3p, because x = 3p
(x,y) = (3p, y) .... replace x with 3p
(x,y) = (3p, 3p+4) ... replace y with 3p+4
