Answer:
P = 47.1 units
Step-by-step explanation:
the perimeter of the pair of straight opposite sides is 11+11, or 22
now you have 2 semi-circles, which equals 1 full circle which, if we find the circumference to then we just add it to 22 to get the entire answer
Circumference of circle with diameter of 8:
C = 2πr
C = 2π(4)
C = 8π
C = 25.13
now add 22 + 25.13 to get 47.1 rounded to nearest tenths place
It would be zero because x can’t be less or more in this particular situation.
Insert x = 100 and x = 200 in the function
f(100) = 20,000 - 40*100
= 20,000 - 4000
= 16,000
f(2)) = 20,000 - 8,000 = 12,000
So its choice C , All reals between 12,000 and 16,000 inclusive.
Answer:
cotΘ = 
Step-by-step explanation:
Using the trigonometric identity
cot x = 
, then
tanΘ = 
= 
, hence
cotΘ = 
=
Answer:
y = 5x
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition that y = 30 when x = 6
k = 
= 
= 5
y = 5x ← equation of proportion
