Make p the subject of the formula k = root p-3r
Answer:
p = k ^2 + 3 r
Step-by-step explanation:
The solution of the given equation k = √(p - 3r) for p will be p = k² + 3r.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
As per the given equation,
k = √(p - 3r)
Square on both sides as,
k² = (√(p - 3r))²
k² = p - 3r
Add 3r on both sides as
k² + 3r = p - 3r + 3r
k² + 3r = p
Hence "The solution of the given equation k = √(p - 3r) for p will be p = k² + 3r. ".

Sue is reading a book of 360 pages. She read some of the book last week. She plans to read 46 pages today. When she does, she will be 4/5 of the way through the book. How many pages did she read last week?
Answer: She read 242 pages last week.
Step-by-step explanation:
Total pages = 360
Let the number of pages she read last week = x
( Pages read last week) + (Pages read today) = [tex]\dfrac45[/tex] (Total pages)
i.e. [tex]x+46=\dfrac45(360)[/tex]
[tex]\Rightarrow x+46=288\\\\ \Rightarrow x= 288-46\\\\ \Rightarrow x=242[/tex]
Hence, she read 242 pages last week.

An artist spent $75 on supplies to create paintings. Each painting the artist created was sold for $25. Which function can be used to find p, the profit when c paintings are sold?
Answer:
Step-by-step explanation:
The function can be used to find p, the profit when c paintings are sold is p = 25x - c.
Given that, an artist spent $75 on supplies to create paintings.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Let the x be the number of paintings sold.
Now selling price of articles = $25x
Profit (p) = 25x - c
Hence, the function can be used to find p, the profit when c paintings are sold is p = 25x - c.
