Answer:
19.2
76.8
Step-by-step explanation:
density × volume = mass
mass = 62.4 × (pi × (40/2)² × h)
mass = 78,374.4h
WD = m×9.8×h = 9.8mh
WD = 768,069.12h²
At h = 5
WD = 768,069.12×5²
= 19,201,728 ft-lb
= 19.2 million ft-lb
At h = 10
WD = 76,806,9.12 × 10²
WD = 76,806,912 ft-lb
= 76.8 million ft-lb
Answer:
Step-by-step explanation:
<u>Given:</u>
<u />
⇒ Slope-Intercept Form: y = mx + b
<u>where:</u>
- m is the slope
- b is the y-intercept (when x = 0)
Substitute the given values:

First find the equation of y.
Find the slope m.
.
Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.
.
The equation of a line y is:
.
The perpendicular line 
is same like the normal line except its slope m becomes:
.
The equation of a perpendicular bisector is thus:
.
Hope this helps.
Answer:
No. Rob was correct to extend the lines to the origin, but the points should be on a single straight line. He made two straight lines.
