The equation x2 − xy + y2 = 3 represents a "rotated ellipse," that is, an ellipse whose axes are not parallel to the coordinate

Setler [38]

Answer:

the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)

Step-by-step explanation:

To find the points at which a graphic crosses the x-axis we need to find the values for x where y = 0.

Therefore, in the equation x²- xy + y² = 3 we are going to make y = 0 and solve for x

x² - xy + y² = 3

x²- x(0) + (0)² = 3

x² = 3

x = ±√3

x₁ = 1.73 and x₂ = -1.73

Therefore, the points where the ellipse crosses the x- axis are (1.73, 0) and (-1.73, 0)

The value in dollars, v(x), of a certain truck after x years is represented by the equation v

ikadub [295]

Answer:

The worth of truck is $2,201 more after 2 years than after 3 years.

Step-by-step explanation:

Given: $V(x)=32500(0.92)^x$

The value of truck is depreciate per year using above formula.

We need to find how much more worth of truck after 2 years than 3 years.

First we find the worth of truck after 2 years, put x=2 into formula

$V(2)=32500(0.92)^2$

$V(2)=27508$

The worth of truck after 2 years would be $27,508

Now we find the worth of truck after 3 years, put x=3 into formula

$V(3)=32500(0.92)^3$

$V(3)=25307.36$

The worth of truck after 2 years would be $25,307.36

Now we find difference of both value.

Difference = 27508-25307.36 = $2,201

Hence, The worth of truck is $2,201 more after 2 years than after 3 years.
