The derivative of a variable raised to exponent of n, x^n is equal to the product of n and x raised to exponent of n-1.
d(x^n) = (n)(x^n-1)
So, from the given
d(9x + 5) = (1)(9x^1-0) + 5(0)
= 9
The given value of x is irrelevant to this item because the derivative does not contain any variable x.
Answer:
21 pencils
Step-by-step explanation:
b 21 pencils
1. Turn the fractions in to decimals
2.Add them up
2.13 + 3.5 + 2.5 = 8.13ft
Answer:
An initial amount of 180 grows at a rate of 22% every month.
=> The equation for the amount y after x months:
y = 180 x (1 + 22/100)^x
Hope this helps!

Using a proportional relationship, it is found that the two equations that have the same constant of proportionality are givn by:
с 1 and 3
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the functions and constants are given as follows:
- 3. 8y = 6x -> k = 6/8 = 3/4.
Equations 1 and 3 have the same constants, hence option c is correct.
