Answer: Choice D
(a-e)/f
=======================================
Explanation:
Points D and B are at locations (e,f) and (a,0) respectively.
Find the slope of line DB to get
m = (y2-y1)/(x2-x1)
m = (0-f)/(a-e)
m = -f/(a-e)
This is the slope of line DB. We want the perpendicular slope to this line. So we'll flip the fraction to get -(a-e)/f and then flip the sign from negative to positive. That leads to the final answer (a-e)/f.
Another example would be an original slope of -2/5 has a perpendicular slope of 5/2. Notice how the two slopes -2/5 and 5/2 multiply to -1. This is true of any pair of perpendicular lines where neither line is vertical.
Answer:
STEP 3
Step-by-step explanation:
Francesca drew point (–2, –10) on the terminal ray of angle , which is in standard position. She found values for the six trigonometric functions using the steps below.
A unit circle is shown. A ray intersects point (negative 2, negative 10) in quadrant 3. Theta is the angle formed by the ray and the x-axis in quadrant 1.
Francesca made her first error in step 3 because the sine, cosine, and tangent ratios are incorrect, which also resulted in incorrect cosecant, secant, and tangent functions.

x + y + z
- Substitute the given values for x, y, and z.
(3) + (-5) + (-2)
3 - 5 - 2
- Solve from left to right.
3 - 5 = -2
-2 - 2 = -4
<h3>Your answer is -4.</h3>
Data:
Model: 41cm
Scale: 1cm/24feet
To convert the measure of the model to the real Tower you use the scale factor
The scale factor is 24ft/cm
To know the height of the Eiffel Tower you multiply the height in the model for the scale factor:
Then so, the height of the Eiffel Tower is 984ft
