<u><em>Answer:</em></u>
-23.4 at 9:00 a.m.
<u><em>Step-by-step explanation:</em></u>
Make a ratio with the given numbers: -13, 5.
I believe the "common number" for the ratio of 1 a.m. would be:
2.6<u> : </u>1 times 9 = 23.4<u> </u><u>:</u><u> </u>9
Answer:
Multiply a by 2, then subtract by a, then divide by 4
Step-by-step explanation:
a=(1/2)(4y+a)
2a = 4y + a
a = 4y
y = 4
Answer:
I believe it is C) decreasing when x > -1
Step-by-step explanation:
If you plot all 3 points on a graph, you will notice that the parabola is facing downwards. This means that on the left side of the vertex, it is increasing (the y-value increases). On the right side of the vertex, it decreases (y-value decreases). Note that "decreasing" refers to the y values.
So, since the vertex's x-value is -1 (we know this from the point (-1, 2)), any x-value greater than -1 will be to the right of the vertex. For example, 0, 1, 2, 3, etc. are all greater x-values than -1, so they are all to the right of -1. Since they are on the right, that means the corresponding-values will be decreasing.
Therefore, when x > -1, the parabola is decreasing.
Newton's Law of cooling is
where
T(t) = temperature of the body after t hours, 80 °F
= ambient temperature, 65 °F
= normal body temperature, assumed to be 98.6 °F
