Answer: 0.64sec
Step-by-step explanation:
h= -16t2 + t + 6
a= -16 b=1 c= 6
Using the quadratic equation formular
X = -b ± √b2 - 4ac / 2a
X= -1 ± √1^2 - 4(-16)6 / 2(-16)
=-1 ±√1+384 / -32
= -1 ±√385 / -32
Either X = -1 + 19.62 / -32
= 18.62 /-32
=-0.58 sec
Or X = -1-19.62 / -32
= -20.62 / -32
= 0.64sec
Since there is no negative time, therefore our answer is 0.64sec
Answer:
66 feet
Step-by-step explanation:
30+30=30 feet
6+6=12 yards
1 yard=3 feet
12*3=36
30+36=66
100 cm is equal to 1000m, so yes it is equal

Answer:
see below for a graph
Step-by-step explanation:
The equation is in slope-intercept form, so right away you know one point is the y-intercept: (0, -4).
Another point can be found using the slope, which is 3/2, to go 2 units to the right and 3 units up. (Slope = rise/run, so rise = 3 and run = 2 match the slope.)
