What is being asked here? Are they asking for the passing grade or the total with all the other 90 points added? I think it is A, 90%
Answer:
it is the abstract science of number, quantity and space, either as abstract concept
H=-16t² +v(0)t+h(0)
v(0)=192
h=-16t² +192t+h(0)
h(0) should be 0, because the mortar sits on the ground.
h= - 16t²+192t
This function will have maximum because it has minus before x², and parabola is looking down.
h=-(16t²-192t)=-(16t² -2*4t*24+24²)+24²
h=-(4t-24)²+24²
h=-(4t-24)²+576
vertex (24 feet, 576 feet)
24 feet horizontally from the mortar and 576 feet up
Answer:
140
-2.6
0
Step-by-step explanation:
60 -(-80) if there is - - that means +
60 + 80 = 140
2.3 + (-4.9) if its + - it just means - ignore the plus
2.3 - 4.9
-2.6
4.5 + (-4.5)
0
