Profit, P(r), is the difference between revenue, R(r), and cost, C(r), so P(r) = R(r) - C(r) Which expression represents P(r), i
GuDViN [60]

The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

<h3>What is an equation? </h3>

An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.

Profit is the difference between revenue and cost. Given that:

R(r) = 2r⁴ - 3r³ + 2r - 1 and C(r) = r⁴ - r² + 2r + 3

P(r) = R(r) - C(r)

P(r) = (2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4

The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

Hey Mahfia, please help! Find an equation in standard form for the hyperbola with vertices at (0, ±10) and asymptotes at
Dafna1 [17]

Answer:

\huge\boxed{  \red{ \boxed{ \tt{ \frac{ {y}^{2} }{ {10}^{2} }  -  \frac{ {x}^{2} }{ {12}^{2} }  = 1}}}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • conic sections
  • PEMDAS
<h3>tips and formulas:</h3>
  • \sf hyperbola \:equation :  \\  \sf  \frac{ {x}^{2} }{ {a}^{2} }   -  \frac{ {y}^{2} }{ {b}^{2} }  = 1
  • vertices of hyperbola:(±a,0) and (0,±b) if reversed
  • \sf \: asymptotes :  \\ y =   \pm\frac{b}{a} x
<h3>given:</h3>
  • vertices: (0,±10)
  • the hyperbola equation is inversed since the vertices is (0,±10)
  • asymptotes:\pm \frac{5}{6}x
<h3>let's solve:</h3>
  • the asymptotes are in simplest and we know b is ±10

according to the question

  1. y =  \sf  \frac{5 \times 2}{6 \times 2} x \\ y =  \frac{10}{12} x

therefore we got

  • a=12
  • b=10

note: the equation will be inversed

let's create the equation:

  1. \sf substitute \: the \: value \: of \: a \: and \: b :  \\  \sf  \frac{ {y}^{2} }{ {10}^{2} }  -  \frac{ {x}^{2} }{ {12}^{2} }  = 1

Diana is a piano teacher who charges $45 per hour plus an additional flat fee of $20 for travel. The equation that represents th
nikklg [1K]

To shift vertically the graph of the function f(x), you have to add a constant to its expression:

f(x) \to f(x)+k

If k is positive, you shift the function k units above, if k in negative, you shift the function k units below.

So, if you want to shift the graph of f(x)=45x+20 two units down, you have to subtract 2 (i.e., add -2):

f(x) = 45x+20 \to 45x+20-2 = 45x+18
