- A particle moving with uniform acceleration of 1.25 metres per square second passes through three points P, Q
and R in a straight line. If PQ = 95m and QR= 90m and the particle takes 30 seconds and
20 seconds to cover PQ and QR respectively, find the speed of the particle at P and its
acceleration.

answer: 1 + 1 = 11

step-by-step explanation:

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

i would say b) is your answer
