Answer:f=1800/d Inverse proportion function. Provided f is in pounds & d is in inches.
Step-by-step explanation: the relationship between f & d is inverse proportion.
A constant k has to be derived from the relationship.
If f is inversely proportional to d then f=k(1/d)
K= f X d
= 50 X 36
=> constant K=1800.

Answer:
164.32 earth year
Step-by-step explanation:
distance of Neptune, Rn = 4.5 x 10^9 km
distance of earth, Re = 1.5 x 10^8 km
time period of earth, Te = 1 year
let the time period of Neptune is Tn.
According to the Kepler's third law
T² ∝ R³
Tn = 164.32 earth years
Thus, the neptune year is equal to 164.32 earth year.
Step-by-step explanation:
r(b) = 12b
c(b) = 4 + 3.3b
I think profit is revenue minus the cost, so p(b) = r(b) - c(b)
= 12b - (4 + 3.3b)
12b - 4 - 3.3b //Combine like terms
8.7b - 4
Answer: D

Hello :
f(x) = sin²(x) +cos(x)
the dirivate is : f'(x) = 2sin(x) cos(x) -sin(x) because :
( sin²(x) )' = 2sin(x) cos(x) and (cos(x))' = - sin(x)
f'(x) = 0 : sin(x) (2cos(x) - 1) = 0
sin(x) = 0 : x = k <span>π k in Z
</span>2cos(x) - 1 =0 : 2cos(x) =1
cos(x) = 1/2 = cos( π /3)
x = π /3 +2k π or x = - π /3 +2k π
in intervall : <span> <span>[0
, 2π] :
k=0 : x= 0 f(0) = 1 ( </span></span>minimum<span>)
</span>k=1 : x = π f(π) = -1 (<span>minimum)
x= </span> π /3 f ( π /3 ) = 1.25 ( <span>maximum)</span>
