Answer:
C and D
Step-by-step explanation:
in equations y=4x+9 and y=4x-9 you have the same slope (4) so paralleling is guaranteed.
y=9 and y=18 you can understand as y=0x+9 and y=0x+18, so in this situation you have the same slope (0), so lines y=9 and y=18 are parallel too.
Answer:
x = 4 units
Step-by-step explanation:
Data provided in the question:
c(x ) = 2x³ - 12x² + 23,000
Now,
For point of maxima or minima, differentiating the above equation with respect to number of items 'x'
c'(x) = 3(2x²) - 2(12x) + 0
or
c'(x) = 3(2x²) - 2(12x)
for point of maxima or minima put c'(x) = 0
Thus,
3(2x²) - 2(12x) = 0
or
6x² - 24x = 0
or
x² - 4x = 0
or
x(x - 4) = 0
or
x = 0 and, x = 4
Since,
The quantity cannot be zero
Therefore,
production level that will minimize the average cost of making x items is x = 4 units
Answer:
12.56
Step-by-step explanation:
area of a circle is A=πr^2
radius is 2
a= 3.14 (2)^2
=3.14 x 4
=12.56
Answer:
Step-by-step explanation:
65+90=155
180-155=25
180-25=155
180 because it is the angle of a straight line
180 because it is the total angle of a triangle
