Answer:-6
Step-by-step explanation:
Answer:
A: 9 seconds
B: 144 ft.
Step-by-step explanation:
A:
Let t = no. of seconds for them to meet
When they meet the sum of their distances is 270 ft, dist = rate * time
16t + 14t = 270
30t = 270
t = 270/30
t = 9 seconds
B:
He ran 9 sec at 16 ft/sec, therefore:
9 * 16 = 144 ft
Answer:
Step-by-step explanation:
a = - 4
b = 10
c = - 8
The discriminate is
D = b^2 - 4ac
D = 10^2 - 4*(-4)(-8)
D = 100 - 128
D = - 28 which is not a nice number
Because the Discriminate has a minus result, there are no real zeros.
Answer:
Step-by-step explanation:
D=106
E=54
F=20
D is an AEA im pretty sure meaning itʻll be equal to 106
E Is a vertical angle to 54
and for F everything will equal to 180 so 180-106-54=20
I hope this helps have a good day!
