Hello,
A=(4,2)
B=(2,8)
(AB)≡y-2=(x-4)*(8-2)/(2-4) ==> y=-3x+14
(BC)≡y-8=(x-2)*1/3 ==> y=1/3 x+22/3
Answer:
change in y / change in x
Step-by-step explanation:
-4/8
=-1/2
Answer:
20 rad/sec
Step-by-step explanation:
The formula we are going to use is ![v=\omega r](https://tex.z-dn.net/?f=v%3D%5Comega%20r)
Where
v is the linear velocity (here given 60 ft/s)
is the angular velocity (what we sought to find)
r is the radius (which is half of diameter, hence, 6/3 = 3 ft)
<em>Plugging these numbers in, we find the angular velocity as:</em>

<u><em>Note: </em></u><em>the units is radians per second (rad/s)</em>

Correct answer 20 rad/sec
It appears that you have here a list of the # of minutes spent each day on HW, and that y ou need to sum up this list to answer the question. Unfortunately I cannot read the last numeral.
The answer (assuming that my guess is correct) would be found as follows:
Total hours spent on HW in one week = (18+20+22+11+19+18+ ?? )
Answer:
48π + 120
Step-by-step explanation:
Lateral area of a cylinder = Ch = πdh
1/4 of the lateral area = 12π(10)/4 = 30π
Bottom area = 6(10) = 60
Front area = 6(10) = 60
Area of base = πr^2/4 = 36π/4 = 9π
Area of two bases = 18π
Total area = 18π + 30π + 60 + 60 = 48π + 120
