Answer:
Step-by-step explanation:
The slope of straight line PR where P(2,3) and R(5,-1) are two vertices of triangle PQR will be =
Therefore, the slope of the altitude passing through Q(-1,1) will be
{Since, the product of slopes of two perpendicular straight line is -1}
So, equation of the altitude is
where c is a constant.
Now, putting x = -1 and y = 1 in the above equation we get
⇒
Therefore, the equation of the altitude is
(Answer)
8,-2. place the x as 8 and y as -2.
70 miles per hour
5280 feet per mile
5280 x 70 = 369600 feet per hour
3600 seconds per hour
369600 divided by 3600 =
102.67 feet per second (rounded to the nearest hundredth)
Rob scored 34 points. 88-54=34
Answer:
72.14 units
Step-by-step explanation:
Let A(8,13), B(5,-18),C(-6,-6) and D(-2,-5)
Apply the distance formula as;

Finding the lengths of the segments
For AB

For BC

For CD

For DA

Finding the perimeter will be;
31.14+16.28+4.12+20.6=72.14 units
