Answer:
Step-by-step explanation:
Putting value of n = - 8 in the equation
F(n) = 2n− 5
F(-8) = 2(-8) - 5
= - 16 - 5 = - 21
step 1
find the slope AB
A = (-3, -1) and B = (4, 4)
m=(y2-y1)/(x2-x1)------> m=(4+1)/(4+3)------> m=5/7
step 2
find the slope mBC
we know that
if two lines are perpendicular
then
the product of their slopes is equal to -1
so
mAB*mBC=-1-------> mBC=-1/mAB-----> -1/(5/7)-----> mBC=-7/5
step 3
with mBC and the point B = (4, 4) find the equation of the line BC
y-y1=m*(x-x1)-----> y-4=(-7/5)*(x-4)-----> y=-(7/5)*x+(28/5)+4---> y=-(7/5)*x+(48/5)
y=-1.4*x+9.6
therefore
the answer is
the equation of the line BC is
y=-1.4*x+9.6

Answer:
The volume of right circular cylinder is 1540 cubic inches.
Step-by-step explanation:
Diameter of right circular cylinder is 14 inches
Radius of right circular cylinder is 7 inches
Height of cylinder is 10 inches
The volume of any cylindrical shaped object is given by :
So, the volume of right circular cylinder is 1540 cubic inches.
We can estimate by round those two different ways. 33.6 would round down to 30 and 82.1 to 80. So 30 x 80 = 2400. Or you can do 34 x 82 = 2788
