3.8 is the answer you already figured it out
The first thing we must do for this case is find the volume of the sphere.
The volume is given by:
V = (4/3) * (pi) * (r ^ 3)
Where,
A: Radius of the sphere
Substituting values:
V = (4/3) * (3.14) * (4 ^ 3)
V = 267.95 in ^ 3
Then, the weight of the sphere is:
W = (267.95) * (0.75)
W = 200.9625 pounds
Round to the nearest pound:
W = 201 pounds
Answer:
The weight of the sphere is:
W = 201 pounds
Answer:
3960 feet per minute
Step-by-step explanation:
multiply the speed value (45) by 88
Answer:
Option B: x > 0
Step-by-step explanation:
Option A is wrong because 
will be 0. So, the inequality can't be divided by 0.
Option C is wrong because 1 will suffice this inequality. 
Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).
Leaving us with only option B, which is the right answer.
Answer:
X2+8X+6=0
We add all the numbers together, and all the variables
X^2+8X+6=0
a = 1; b = 8; c = +6;
Δ = b2-4ac
Δ = 82-4·1·6
Δ = 40
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
X1=−b−Δ√2aX2=−b+Δ√2a
The end solution:
Δ−−√=40−−√=4∗10−−−−−√=4√∗10−−√=210−−√
X1=−b−Δ√2a=−(8)−210√2∗1=−8−210√2
X2=−b+Δ√2a=−(8)+210√2∗1=−8+210√2
