An inequality that can be used to describe this situation would be;
A. |t - 2| < 4
-2 is the fall in temperature, whereas the overall temperature should be less than 4.
Answer:
66%, 69%, 72%
63%, 65%, 67%
67%, 72%, 77%
Step-by-step explanation:
it says that people recommend the same intensity for three then increasing for three then decreasing thus repeating this cycle
so anyways for the fourth fifthe and sixth visit itll be an increasing sensitivity
We have to compute: Δ y / Δ x.
The interval is [ 2, 5 ] and y = 4 x - 9.
y 1 = 4 · 2 - 9 = 8 - 9 = - 1
y 2 = 4 · 5 - 9 = 20 - 9 = 11
Δ y / Δ x = ( y 2 - y 1 ) / ( x 2 - x 1 ) =
= ( 11 - ( - 1 ) ) / ( 5 - 2 ) = ( 11 + 1 ) / 3 = 12 / 3 = 4
Answer:
Δ y / Δ x = 4
Answer:
d -39
Step-by-step explanation:
d/13-3
multiply both sides by 13
d 13(-3)
d -39
hope this helps
Check the picture below.
so the parabola looks more or less like so, bearing in mind that the directrix is a horizontal line, thusu the parabola is a vertical one, so the squared variable is the "x".
The vertex is always half-way between the focus point and the directrix, as you see there, and the distance from the vertex to the focus is "p" distance, since the parabola is opening downwards, "p" is negative, in this case -2.
