Answer:
Values for x = -1 + 7i and -1 - 7i
Step-by-step explanation:
we have an equation,
(x+1)^2 = -49
We need to solve this equation for all values of x:
(x+1)^2 = - 49
Taking square root both sides
√((x +1)^2) = √-49
x + 1 = ± 7i
Subtract both sides by 1
x = -1 ± 7i
Hence we get two values for x = -1 + 7i and -1 - 7i
If 64 = 66(2/3x), then 64/66 = 2/3x, then approx 0.97/(2/3) = x, so x = approx 1.45
Volume of sphere = 4/3πr³
r is radius.
Radius = diameter/2 = 16/2 = 8
Volume = 4/3(3.14)(8)³
Volume = 2143.57
Rounded to nearest tenth would be 2144.7 in³
The answer is D.
Hope this helps :)
Answer:The Alternate Exterior Angles Theorem states that if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent. Here we have a new pair of lines, parallel and crossed by a transversal.
