It's the first one (7+4i)+(7-4i)=14
Answer:
y = -5x - 25
Step-by-step explanation:
Substitute into form of y - y1 = m(x - x1): (Take the point (-7,10) for x1 & y1, m would be the slope)
y - 10 = -5(x -(-7))
y - 10 = -5(x + 7)
y - 10 = -5x - 35
y = -5x - 25

Answer: The volume is 942 cubic feet , 942 ft^3
Step-by-step explanation:
The formula for the volume of a cylinder is v = pi* r^2 * h
Where v is the volume, r is the radius and h is the height.
Input the values for pi, radius, and the height into the formula to solve for the volume.
v = 3.14* (5^2) * 12
V = 3.14* 25 * 12
V = 942
