-4 + -10 = -14
Negative 4 plus negative 10 = negative 14 (thats what I think the answers gonna be, but im not that sure though)
Answer:
x = 7/2 ± 3/2*(i√3)
Step-by-step explanation:
The equation is
(x - 5)^2 + 3(x - 5) + 9 =0
Let A = (x-5)
The equation becomes now
(A)^2 + 3(A) + 9 =0
We then apply the quadratic formula
A = [-(3) ± √((3)^2-4(1)(9)) ]/ (2(1))
A = -3/2 ± 3/2*(i√3)
Now, we revert the substitution
(x-5) = -3/2 ± 3/2*(i√3)
x = 7/2 ± 3/2*(i√3)
Answer:
The line passes through the point ( x1 , y1 ) = ( 3 , 9 ). Hence 2x - y + 3 = 0 is the required equation of the line
Hope that helps

Answer:
The volume of sphere is 500 in³
Step-by-step explanation:
Given:
Diameter of sphere is 10 in.
Now, to find the volume we need radius.
Radius(r) = half of the diameter


And, now putting the formula to get the volume of sphere:

Putting the value of π = 3.



So, the volume is 522.025 in³.
By estimating the value the volume is 500 in³.
Therefore, the volume of sphere is 500 in³.
