Answer:
m(u) = -0.25(u +2)² +1 or -0.25u² -u
Step-by-step explanation:
The equation is fairly easily written in vertex form, as the vertex point is on a grid line intersection at (-2, 1). The parabola opens downward, so the scale factor is negative.
The vertical change from the vertex is only a fraction of a unit when u differs from the vertex by 1. It is 1 unit when u differs from the vertex by 2, so the magnitude of the vertical scale factor is 1/2² = 1/4.
Our equation will be of the form ...
m(u) = (vertical scale factor)(u - (horizontal vertex location))² + (vertical vertex location)
For this graph, the equation is ...
m(u) = -0.25(u +2)² +1
or, simplifying, we get ...
m(u) = -0.25u² -u
Yeah I think x=12y on this one correct me if I’m wrong
Answer
last one
Step-by-step explanation:
First you'd convert the seconds into minutes by dividing.
18,000 / 60 (60 secs in a min) = 300 minutes
Then, similarly, you would convert the minutes into hours.
300 / 60 (60 mins in an hr) = 5 hours
The answer is 5 hours.
If you multiply 6 * 5 you get 30. 30 * 103 = 3,090
There are 2 zeros in the product of (6x5)x103
