Answer:
NOR = 126.6
Step-by-step explanation:
one full circle would have 360 degrees
so we can make an equation that shows all of our angles adding up to 360:
NOQ + QOR + NOR = 360
we know that NOQ is 147.7
we know that QOR is 85.7
substitute these into our equation:
147.7 + 85.7 + NOR = 360
add like terms:
233.4 + NOR = 360
subtract 233.4 from both sides:
NOR = 126.6

Next time, please share the possible answers (which here are graphs).
f(x)=x^3+x^2+x+1 builds upon the cubing function x^3, which starts in Quadrant III and continues into Quadrant I. f(x)=x^3+x^2+x+1 displays the same behavior. Note that if x = 0, f(0) = 1, so the y-intercept is (0, 1).

Answer:
Find the answers in the explanation
Step-by-step explanation:
The given function is
f(x)=475-15x
A.) To find f^-1 and explain what it represents in this situacions, let f(x) = y. That is,
Y = 475 - 15x
Interchange y and x and make y the subject of formula
X = 475 - 15y
-15y = x - 475
Y = 475/15 - x/15
Y = (475 - x) / 15
Therefore,
f^-1(x) = (475 - x) / 15
If the function depreciates the smartphone, then, the inverse function will appreciate it.
When will the deprecated value of smart phone be less than $100.00
Substitute 100 for f(x) and find x
100 = 475 - 15x
-15x = 100 - 475
-15x = - 375
X = 375/15
X = 25
Therefore, the deprecated value of smart phone be less than $100.00 in the next 26 months.
what does x represent in f^-1(x) =30?
X represent the number of months for the smartphone appreciations
What is the value of x?
Substitute the inverse function for 30 and make x the subject of formula in the equation
f^-1(x) = (475 - x) / 15
30 = (475 - x) / 15
Cross multiply
450 = 475 - x
X = 475 - 450
X = 25 months
Graph f(x) and f^-1 (x) on the same coordinate
