Answer:x
= -1 +√
3(3 + y)
Step-by-step explanation: solve the equation for x by finding a, b and c of the quadratic then applying the quadractic formula
P(A)=0.2
P(B)=0.3
P(A and B)= 0.2 x 0.3=0.06

<span>For example
let there be 100 students
so the number of girls=40
20% of girls=20%of40=20*40/100=8 wear glasses
Which means 8 out of 100 students wear glasses
So 8%students wear glasses</span>
a) Acceleration is the derivative of velocity. By the fundamental theorem of calculus,
so that
b) We get the displacement by integrating the velocity function like above. Assume the object starts at the origin, so that its initial position is 
. Then its displacement over the time interval [0, 3] is
c) The total distance traveled is the integral of the absolute value of the velocity function:
for 
and 
for 
, so we split the integral into two as
