Well whatever is in the absolute value sign is always positive.
Answer:
The horizontal distance from the center is 49.3883 feet
Step-by-step explanation:
The equation of an ellipse is equal to:
Where a is the half of the wide, b is the high of the ellipse, x is the horizontal distance from the center and y is the height of the ellipse at that distance.
Then, replacing a by 106/2 and b by 33.9, we get:
Therefore, the horizontal distances from the center of the arch where the height is equal to 12.3 feet is calculated replacing y by 12.3 and solving for x as:
So, the horizontal distance from the center is 49.3883 feet
The answer is in the picture...
Answer:
Step-by-step explanation:
1. Convert to slope intercept form (y=mx+b)
2. Find slope (the 'm' in mx)
3. Find slope of perpendicular line
So for the first question:
Convert to slope Intercept form if necessary:
3x+4y=12
4y=12-3x<<Subtract by 3x
y=3-<u>3/4</u>x<<Divide by 4
Find slope
y=3-<u>3/4</u>x
3/4 is the slope
Find slope of perpendicular line
To find the slope of a perpendicular line, you just have to take the reciprocal of the original slope and take the opposite sign.
Here is what I mean:
3/4<<original slope
4/3<<reciprocal
-4/3<<opposite
So for the first question -4/3 is the answer.
Now you can do the rest! Hope this helps!
