Answer:
Step-by-step explanation:
when h(t)=0
-4.9 t²+19.6t=0
4.9t(-t+4)=0
either t=0 or t=4
so domain is 0≤t≤4
for range
h(t)=-4.9t²+19.6t
=-4.9(t²-4t+4-4)
=-4.9(t-2)²+19.6
so range is 0≤h≤19.6
Answer:
79
Step-by-step explanation:
The sum of the three interior angles in a triangle is always 180°
180-73-28 = 79
The other side would have a length of 5m
Answer:
0.4375
Step-by-step explanation: calculator
Add 22.3 twice which is 44.6 then add 28.4 twice which is 56.8 and then add 44.6 plus 56.8 which is 101.4, 101.4 is your answer
