Answer:

See explanation!

Step-by-step explanation:

We are given a graph that shows the value (in dollars) of a car stereo at time t (in years) the time t=0 represents when the stereo was purchased.

A. What does the y-intercept mean in terms of the problem? Include the time and the value of the stereo in your answer.

The graph given shows an exponential expression with a y-interept at

$V_{(t=0)} = 300$ dollars.

This denotes that the initial value of a car stereo at year 0 (i.e. when it first entered the market) was at 300 dollars.

B. What does V(5)=98 mean in terms of the problem?

Looking at the graph for $V(5)=98$ , we know that we are looking at a point $(x,y)$ equal to $(5,98)$ .

This denotes that at year $t=5$ , the car stereo value was $98$ dollars. Thus since the stereo entered the market the value of the car stereo has decreased by over ≈ 202 dollars.

C. Is the graph increasing or decreasing? What does this mean in terms of the problem?

The graph is Exponentially Decreasing suggesting that as the year $t$ increase, the value of the car stereo is quickly decreasing by larger amounts and not in a linear manner (i.e. the value does not decrease by the same amount every year).

Is y=x squared +2 a linear function

ollegr [7]

No, this would not be a linear function. Being linear means it creates a straight line, but this function has an x squared. Anytime x^2 is in a function, the graph is a u shape, called a parabola. A simple linear function is y=x :D

Find dy/dx by implicit differentiation. y cos x = 5x2 + 3y2

lbvjy [14]

Step 1:
Start by putting $\frac{d}{dx}$ in front of each term

$\frac{d}{dx}[y cos x]= \frac{d}{dx}[5x^2]+ \frac{d}{dx}[ 3y^2]$
-----------------------------------------------------------------------------------------------------------------
Step 2:

Deal with the terms in 'x' and the constant terms
$\frac{d}{dx}[ycosx]= 10x+ \frac{d}{dx} [3y^2]$
----------------------------------------------------------------------------------------------------------------
Step 3:

Use the chain rule for the terms in 'y'
$\frac{d}{dx}[ycosx]=10x+6y \frac{dy}{dx}$
--------------------------------------------------------------------------------------------------------------
Step 4:

Use the product rule on the term in 'x' and 'y'
$(y) \frac{d}{dx} cos x+(cos x) \frac{d}{dx}y =10x+6y \frac{dy}{dx}
$
$y(-siny)+(cosx) \frac{dy}{dx} =10x+6y \frac{dy}{dx}$
--------------------------------------------------------------------------------------------------------------

Step 5:

Rearrange to make $\frac{dy}{dx}$ the subject
$-y sin(y)+cos(x) \frac{dy}{dx} =10x+6y \frac{dy}{dx}$
$cos(x) \frac{dy}{dx}-6y \frac{dy}{dx}=10x+y sin(y)$
$[cos(x) - 6y] \frac{dy}{dx}=10x + y sin(y)$
$\frac{dy}{dx}= \frac{10x+ysin(y)}{cos(x)-6y}$ ⇒ Final Answer

Sandra is a real estate agent and rams 5000 commission on the selling of a 62,000 house. what is the percent of commission she r

sveta [45]

To find a percent, you use this simple formula:
5000/62000 = x/100

In this case, x is going to be your percent of commission.

So, to find this, you first divide 5000 by 62000, which is about equal to 0.08.

Now your equation looks like this:
0.08 = x/100

Next, you multiply both sides by 100 to reverse the operation. Now, your equation will look like this:

8 = x

So, the answer is 8%.
