A disc is thrown into the air with an upward velocity of 20 ft/sec. Its height h in feet after t seconds is given by the functio
labwork [276]

Answer:

Time t = 1.39 seconds

Step-by-step explanation:

Given;

Initial velocity v = 20 ft/sec

height equation;

h = -16t^2 + 20t + 6

How long does it take for the disc to be caught 3 feet off the ground;

At this point h = 3

Substituting h = 3 into the height equation;

3 = -16t^2 + 20t + 6

-16t^2 + 20t + 6 - 3 = 0

-16t^2 + 20t + 3 = 0

Solving the quadratic equation;

t = 1.39 or t = -0.14

Since t cannot be negative;

Time t = 1.39 seconds

Four friends ordered a pizza cut into eight slices. The whole pizza was eaten, with each friend eating a different number of sli
raketka [301]

Answer:

{0,1,3,4}

Step-by-step explanation:

Given, total no of slices=8.

Total no of friends=4.

also each friend didnt ate more than the other three.

let a,b,c,d be no of slices ate by the friends 1,2,3,4 respectively.

given sum of a+b+c+d=8.

now applying the second condition

a\leq b+c+d \\b\leq c+d+a\\c\leq a+b+d\\d\leq a+b+c

so each of a,b,c,d must be less than or equal to 4.

which means 5 values are possible{0,1,2,3,4}.from this set you have to select 4 values such that their sum is 8.hence, those values are {0,1,3,4}.
