Find the maximum of y=-x^2-4/3x +5

49/9

y=-x^2-4/3x+5

(h,k)

h = minimum

k/y = maximum

h = -b/2a

a = (-1)x^2

b = (-4/3)x

h = 4/3 / -2 = -2/3

To find the maximum, take the minimum and replace it with every "x" in the equation.

y = -(-2/3)^2-4/3(-2/3)+5

y = 49/9

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
