Answer:
I think number 17 is depends on the type of substance
18 is no.
Step-by-step explanation:
You need the height and length to find square inches.
Answer:
a) 15.52ft
b) 0.47 secs
Step-by-step explanation:
h = -16t^2 + 15t + 12
The maximum height is reached after -b/2a seconds
a = -16 , b = 15, c= 12
-b/2a = -15/2(-16)
= -15/-32
= 0.47 secs
The maximum height = -16(0.47)^2 + 15(0.47) + 12
= -3.5344 + 7.05 + 12
= 15.5156
= 15.52ft
Answer:
b) -2/3
Step-by-step explanation:
2X + 3Y = - 12
3Y = -2X - 12
Y = - 2/3X - 6
SLOPE = - 2/3
0 is the middle number between negative numbers and positive numbers. Since 1/2 is positive, we know that 1/2 is greater than 0.
