11. K= 1/3
Because 2^3=8. 2x2x2=8
Here is a function rule that produces an output of 7 for an input of 1.6
f(x) = x + 5.4
when x = 1.6, f(x) = 1.6 + 5.4 = 7
Equation of a line tha passes through thte point (x1,y1) and has a lsope of m is
y-y1=m(x-x1)
given
m=1/2
point is (2,-1)
x1=2
y1=-1
y-(-1)=1/2(x-2)
y+1=1/2(x-2)
if yo want slope intercept
y+1=1/2x-1
y=(1/2)x-2
The domain of P(x) will be :
or [0, 160]
<u><em>Explanation</em></u>
Given function : P(x) = $355x - $33,984
Domain means the set of possible values of x , for which the function P(x) can be defined.
Here, x represents the number of passengers on board the plane. As the number of passengers can't be in negative, so the <u>minimum value of x will be 0</u>.
Given that, the plane has a maximum seating capacity of 160 passengers. It means the <u>maximum value of x is 160</u>.
So, the domain of P(x) will be :
or [0, 160]
