The coordinates of the parabolas vertex is (1,-5)
Next, the domain is (-infinity, infinity) and so is the range.
The minimum is -5 and the maximum is infinity.
I hope this helps!
Answer:
7.99 m
Step-by-step explanation:
The formula for the circumference (C) of a circle in terms of its radius (r) is ...
C = 2πr
Putting in the given values, we can find r.
50.2 = 2·3.14·r
50.2/6.28 = r ≈ 7.99 . . . . . divide by the coefficient of r; round to 3 significant figures.
To 3 significant figures, the radius is 7.99 meters.
___
Rounded to the nearest tenth meter, it is 8.0 m.
Answer:65 cm
Step-by-step explanation:
Answer:
The system has no solution.
Step-by-step explanation:
Write the system as
y - 4x =3
2y - 8x = 3
The 2nd equation can be written as
2(y - 4x)
and the system would be
y - 4x =3
2(y - 4x) = 3
Now, call y -4x = z. Then we would have the system
z = 3
2z = 3
But if z =3 then 2z = 6 and we have a contradiction.
We conclude that the system has no solution.
