It has been given that y varies inversely with x, therefore the equation for this relationship is as follows;
y =
\
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
5 = k/x
when we divide 1)/2), k gets cancelled
x = -18*6/5
x = -21.6
when y = 5, then x = -21.6
Answer:
36
Step-by-step explanation:
Givens
a = 312
d = -6
n = 47
Formula
L_n = a + (n - 1)*d
Solution
L_n = 312 + (47 - 1) * -6
L_n = 312 + 46*(-6)
L_n = 312 - 276
L_47 = 36
Answer:
x = 8
Step-by-step explanation:
All sides are equal in terms of symmetry, such as the 5 and 5 opposite the angle 120 that repeats itself at the centre 3 times

Answer:
$562,500 per hour
Step-by-step explanation:
The cost will be a minimum where C'(x) = 0.
C'(x) = 0.56x -0.7 = 0
x = 0.7/0.56 = 1.25
The cost at that production point is ...
C(1.25) = (0.28×1.25 -0.7)1.25 +1 = -0.35×1.25 +1 = 0.5625
The minimum production cost is $562,500 per hour for production of 1250 items per hour.
_____
<em>Additional comment</em>
This is different than the minimum cost <em>per item</em>. This level of production gives a per-item cost of $450. The minimum cost per item is $358.30 at a production level of 1890 per hour.
Answer:
Step-by-step explanation:
studying Math 65
Studying science 50
studying both 35
student are studying in the college are:(65+50)-35=80 students
student studying math only= 65-35=30
student studying science only = 50-25=15
