HELP!! DONT STEAL MY POINTS OR ANSWER AND THEN DELETE IT!! Which is the orthocenter of a triangle with vertices (-2, 1), (3, 4), and (3, -4) ?
Answers
Answer:
(0, 1)
Step-by-step explanation:
The orthocenter is the point of intersection of the altitudes of the triangle. Each altitude is a line through a vertex and perpendicular to the opposite side.
In the attached, we labeled the points A, B, C in the order given. Side BC of the triangle is vertical, so the horizontal line through A will have equation ...
y = 1
The line AC can be seen on the graph to have slope -1, so the altitude through point B will have slope 1. Its equation will be ...
y = x+1
Then the point of intersection will be where ...
y = y
1 = x+1
0 = x
That is, the orthocenter is the point (x, y) = (0, 1).

(i) $1528.80
(ii) $2402.40
(iii) $41.39/h; 13.7% increase
Step-by-step explanation:
(i)The weekly wage is found by multiplying hours by the number of dollars for each hour:
weekly wage = (42 h)($36.40/h) = $1528.80
__
(ii)58 hours of work represents a straight week and 58 -42 = 16 hours of overtime. The overtime rate is 1.5×$36.40 = $54.60 per hour. Then the overtime pay is ...
(16 h)($54.60/h) = $873.60
The technician's total wage for 58 hours of work is ...
total wage = straight pay + overtime pay
= $1528.80 +873.60
total wage = $2402.40
__
(iii)The hourly rate is found by dividing the pay by the corresponding number of hours.
rate = $1490/(36 h) ≈ $41.39 /h . . . . . . . actually 41.38 8/9 per hour
The percentage increase is ...
((new amount) -(original amount))/(original amount) × 100%
= (4.98888...)/36.40 × 100% ≈ 13.7% . . . increase
_____
Additional comment
You may notice that the base weekly wage went down by $38.80 due to the reduced hours.

Using the side proportionality rule of triangles, we can see that the side with length 6 has a [tex]\frac{2}{3}[/tex] ratio to the side with length 9. We can use the same principle to determine that the side length of 2 is two thirds to side length x. We can set up an algebraic equation to find the value of x: [tex]\frac{2}{3} x=2[/tex]. If we multiply both sides by 3, we get [tex]2x=6[/tex], therefore x = 3

Consider the line 4 x + 9 y = 8 . What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?
Answers
Answer:
Parallel line: -4/9 Perpendicular line: 9/4
Step-by-step explanation:
This linear equation is written in standard form: Ax + By = C. First, we isolate the y variable to get the equation: y = -4/9x + 8/9. Now we notice that the slope of this line is -4/9. Parallel lines have the same slope, so the slope of the line parallel to this one is also -4/9. The slope of a perpendicular line is the negative reciprocal of the slope of this line, so the slope of a perpendicular line is 9/4.
