Answer:
![\sqrt[5]{x - 9}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bx%20-%209%7D%20)
Step-by-step explanation:
y=x^5+9
To find inverse function make x the subject, first:
y=x^5+9
y - 9 = x^5
x = ![\sqrt[5]{y - 9}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7By%20-%209%7D%20)
![y^{-1} = \sqrt[5]{x - 9}](https://tex.z-dn.net/?f=y%5E%7B-1%7D%20%20%3D%20%5Csqrt%5B5%5D%7Bx%20-%209%7D%20)
so inverse function of y=x^5+9 is
Length of arc = (15/360) * 2*3.14*20 = 5.23 ins
circumference of the circle = 2*3.14*24 = 150.72
angle at center from 10 ft arc = (10/150.72) * 360 = 23.89 degrees
Answer:
The answer is 360 ways
Step-by-step explanation:
Answer:
C) 18 cents
Step-by-step explanation:
Given,
This weeks deal -
Quantity of Flour Price ($) Price per pound ($)
3 pounds 5.25 (5.25/3) = 1.75
5 pounds 9.75 (9.75/3) = 1.95
7 pounds 12.60 (12.60/3) = 1.80
10 pounds 14.20 (14.20/3) = 1.42
12 pounds 18.24 (18.24/3) = 1.52
The lowest price per pound is $1.42. Therefore, this is the current week's best deal.
The last week's best deal was = $`1.60/pound
The difference between the unit price for previous week's best deal and this week's best deal = $1.60 - $1.42 = $0.18
Therefore, 18 cents.
