Answer:
See explanations below
Step-by-step explanation:
Volume of the sphere is expressed as;
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 3³
V = 4/3 * 3.14 * 27
V = 4 * 3.14 * 9
V = 113.04cube units
For the secind sphere;
diameter = 12
radius = 12/2 = 6
V = 4/3πr³
r is the radius
V = 4/3 * 3.14 * 6³
V = 4/3 * 3.14 * 216
V = 4 * 3.14 * 72
V = 904.32cube units
√106=10.29≈10.3
the answer is B.10
Answer:
y= -2x/3+8
Step-by-step explanation:
find 2 points: (0,8) and (6,4)
substitute in y=ax+b
8=0a+b
b=8
4=6a+b
4=6a+8
6a=-4
a=-2/3
You determine whether the parabola opens upward, with a positive x^2. It opens downward with a negative x^2.
f(x) is a maximum
g(x) is a minimum
Answer:
168 seconds
I edited the answer.
Step-by-step explanation:
To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.
28 x 6 = 168, 24 x 7 = 168
The LCM of 28 and 24 is 168.
So it takes 168 seconds for both lights to flash at the same time.
