2. Suppose that y varies inversely with x. Write an equation for the inverse variation.

Answer:

y=\frac{28}{x}

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

we have

y = 4 when x = 7

Find the value of the constant of proportionality k

k=y*x

substitute

k=(4)(7)=28

therefore

The equation  for the inverse variation is equal to

y=\frac{28}{x}

A small business assumes that the demand function for one of its new products can be modeled by p = Cekx. When p = $40, x = 1000
Maru [420]

Answer:

C= 82.1116

k=-0.0007192

Step-by-step explanation:

p=Ce^{kx}\\40=Ce^{k1000}\\30=Ce^{k1400}\\

Applying logarithmic properties yields in the following linear system:

ln(40) = ln(C) + 1000k\\ln(30) = ln(C) + 1400k

Solving for k:

ln(40) = ln(C) + 1000k\\ln(30) = ln(C) + 1400k\\400 k = ln(30)-ln(40)\\k=-0.0007192

Solving for C:

40=Ce^{-0.0007192*1000}\\C= \frac{40}{e^{-0.0007192*1000}}\\C=82.1116

C= 82.1116

k=-0.0007192

Consider the function. What is the y-intercept of f–1(x)? –16 –12
Mekhanik [1.2K]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

f(x)=x^2+2x-16

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set x=0. In other words, we define the y-intercept (let's call it b as:

b=f(0)

Setting x=0 in our function we have:

b=f(0)=(0)^2+2(0)-16 \\ \\ \boxed{b=f(0)=-16}

So <em>in this context the y-intercept is -16</em>

Then find the area S of the region.<br><br> y=2 x^2, y^2=1/2 x
r-ruslan [8.4K]

Recall that the area under a curve and above the x axis can be computed by the definite integral.  If we have two curves

<span>        y = f(x) and y = g(x)</span>

such that 

<span>        f(x) > g(x) 
</span>
then the area between them bounded by the horizontal lines x = a and x = b is


To remember this formula we write
