Answer:
y= -4 x+3
Step-by-step explanation: A(1, -1)
the equation is y - y (A)=m*( x-x(A) )
y-(-1)=-4(x-1)
y+1=-4x+4
y= -4x+4-1
y=-4x+3
y=-4x+4-1
Answer:
9 seconds
Step-by-step explanation:
d=-16t²+vt+h
The water level will be at 0 level (distance = 0)
0 = 16t² - 90t - 486
8t² - 45t - 243 = 0
(t - 9) (8t + 27) = 0
t = 9 or t = -27
since time should be a positive number, so t = 9 second
Answer: The maximum distance between two antipodal points on the surface of the sphere.
Well 493 divided by 16 actually equals 30.8125. If rounding is allowed in your question, then it's correct, and if not it could be considered incorrect.
