a rocket is launched from the ground. the function h(t)= -4.9t^2 +180t models the height of a rocket launcher from the ground t seconds after it is launched. if all other factors remain the same, which of the following function models the height of a rocket above the ground after t seconds if it is launched from a platform 100 feet in the air? (1) h(t) = -4.9t^2 +280t (2) h(t) = -4.9t^2 +180t -100 (3) h(t) = -4.9t^2 +180t +100(4) h(t) = -4.9t^2 +180 (t+100)

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

she will travel a distance in the range of 3 - 11 miles

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 %
