The angle of depression is 30.47°
My work is in the picture. Do a couple problems with different numbers plugged in for practice.
Answer:
-20x^2 + 53x -18
Explanation:
FOIL
First terms
Outer terms
Inner terms
Last terms
So lets do our F:
5x * -4x = -20x^2
Now lets do our O:
5x * 9 = 45x
Now lets do our I:
-2 * -4x = 8x
Now lets do our L:
-2 * 9 = -18
Lets put all those together:
-20x^2 + 45x + 8x - 18
Combine like terms:
-20x^2 + 53x -18
Answer: 194
Step-by-step explanation:
Since you have a three digit number the hundreth digit is not zero. Then from the fact that h = t -8, t must be 9, then u = 9-5 or 4. Your answer is 194.
None of the equations are parallel or perpendicular to the line jk.
<h3>How to know equations that are parallel and perpendicular?</h3>
The equation of a line can be interpreted as follows:
y = mx + b
where
Therefore,
Parallel lines have the same slope(m).
Perpendicular line follows the principle below:
Therefore, let's find equation of jk
(-5, 5)(1, -5)
m = -5 - 5 / 1 + 5 = -10 / 6 = - 5 / 3
using (1, -5)
-5 = - 5 / 3 (1) + b
b = -5 + 5 / 3 = -15 + 5 / 3 = -10 / 3
Therefore,
y = -5 / 3 x - 10 / 3
m = - 5 / 3
6x + 10y = 11
10y = -6x + 11
y = - 6 / 10 x + 11 / 10
y = - 3 / 5 x + 11 / 10
hence, m = - 3 / 5
5x - 3y = 8
3y = 5x - 8
y = 5 / 3 x - 8/3
m = 5 / 3
