Answer:
2 km east and 10 km north
Step-by-step explanation:
I did the activity and got the right answer.
Factoring, you have
h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)
The ball hits the ground when h(t) = 0, so
0 = -16(t -4)(t +2)
t = 4 or -2
The positive solution is the one of interest.
It will take 4 seconds for the ball to hit the ground.

Answer:
0.375 litres
Step-by-step explanation:
Given that:
Total amount of lemonade held by pitcher = 3 litres
Number of people in which lemonade is to be given equally = 8
Amount of Lemonade received by each person will be:
Total amount of lemonade / number of persons
3 litres / 8
= 0.375 litres
Each person receives 0.375 litres of lemonade
First because it's a broken line we know it's an inequality.
next we find the slope we can take points (0,4) and (2,0) thus (y2-y1)÷(x2-x1)
substituting any value of x for either x1 or x2 and any value of y for y1 and y2 we can get
slope is -2
so now we can take either points to find the equation by the formula
y-yo=m (x-xo) where m is slope
after substitution we can get
y-4=-2 (x-0)
y=-2x+4
