Answer: x = 3 √21
Step-by-step explanation:
you gotta use our good, old, trusty friend pythagorean theorem.
a^2 + b^2 = c^2
x^2 + 6^2 = 15^2
x^2 = 15^2 - 6^2
x^2 = 189
x = √189
x = √27 · 7
x = 3 √3 · 7
x = 3 √21
from question d = 16t^2 = 56-4t
=》 16t^2 -56 + 4t =0
=》 4t^2 - 14 + t = 0
=》 (4t-7)(t+2) =0
=》 t = 1.75 seconds
Answer:
the answer is no.
Step-by-step explanation:
the x-value 2 keeps repeating which makes this not a function.
Answer:
Step-by-step explanation:
solid line means >=
y >= x+1
dotted line mean >
y > -x-2
combining
the system of inequalities is y >= x+1 and y > -x-2
