Answer:
<u>395.64 m³</u>
Step-by-step explanation:
<u>Volume (figure)</u>
- Volume (hemisphere) + Volume (cylinder)
- 2/3πr³ + πr²h
- πr² (2/3r + h)
- 3.14 x 9 (2 + 12)
- 3.14 x 9 x 14
- 3.14 x 126
- <u>395.64 m³</u>
Answer:
i did the first
Step-by-step explanation:
1st way
Standard form: a(X-h)²+k = ( -2/3X² -16/3X -32/3) +32/3 -17/3 = -2/3(X +4)² +5
y = -2/3*X^2-16/3*X-17/3
X = -4 ±√( 15/2) = -6.7386, or -1.2614
Axis of symmetry: X= -4; Vertex (maximum)=(h,k)=( -4, 5); y-intercept is (0,-5.66666666667)
two real roots: X=-1.2613872124776866 and -6.738612787477313
(–2) + 6 + 1 = 1 + 6 + (–2) is B.Commutative Property
