Answer:
75%
Step-by-step explanation:
Here, we are asked to calculate the percentage of a trip that has been completed by Leigh.
Firstly, we identify the total length of the trip, this is 1470km. She stopped 370km from her destination. The length of the distance traveled is 1470km - 370km = 1100km
Now we proceed to calculate what percentage of the journey is this.
We calculate this by placing it over the total length multiplied by 100%
That would be
1100/1470 * 100 = 74.82 approximately 75%
Answer:
x = -1
Step-by-step explanation:
With the axis of symmetry, think of it as where you would slice this line in half, and both sides would look identical to each other. Since this is a quadratic function, this would be at where the vertex is.
The vertex is the part of the line where it "turns" around and starts going the other way. So vertex of this line is at (-1, 3).
Therefore, the axis of symmetry is at x = -1. This is since the function is pointing either up/down, and any value that is x = _ is a vertical line.
Answer:
4) p=b(1/2)
6) y=50+25h
Step-by-step explanation:
Let me know if you need an explanation!
?????????????????????????????
First we have to find the slope of the givent line and for that we use rise / run method .
The points are (-4,4),(4,-2)
Here rise is
And run is
So slope is
And the slopes of perpendicular lines are negative reciprocal of each other .
Therefore the slope of the required perpendicular line is
Now we use slope intercept form, and put x intercept , that is (6,0) and the slope that is 4/3 ,
Therefore required equation is
Correct option is the third option .
