I’m not 100% sure but isn’t it x2 +xy +y2?
Harrizon [31]3 years ago
6 0

Step-by-step explanation:

A = x^2-xy+y^2\\C =x^4+x^2y^2+y^4

We will now divide C with A.

\frac{x^4+x^2y^2+y^4}{x^2-xy+y^2}

Divide x^2, -xy, y^2. Remember that dividing exponents results in subtracting.x^4 / x^2 = x^2\\4 - 2 = 2

So:

\frac{1}{x^2+xy+y^2}

*PLEASE ANSWER* What is the perimeter of the triangle below?
brilliants [131]

Answer:

16.7 Units

Step-by-step explanation:

To find the length of r, you set up the equation as sin(45)= 4.9/r. Then you get r by itself changing it to r = 4.9/sin(45). Then you can find that r = 6.9. Since this is an isosceles triangle, n^1 has to be equal to 4.9. Then you add all the side lengths together. 4.9 + 4.9 + 6.9 = 16.7 units

The sum that represents the number of tickets sold if 35 tickets were sold Monday, half of the remaining tickets were sold on Tuesday and 14 tickets were sold on Wednesday.

To start solving this, we can assign t as the variable to the total number of tickets that were sold. So, t = 35 (for Monday) + (t - 35)/2 (for Tuesday) + 14 (for Wednesday). To solve this, we can say t = 49 + (t - 35)/2, or 2t = 98 + t - 35, which equals t = 63. Therefore, 63 tickets were sold total.

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.
Rasek [7]

Answer: -3.

Step-by-step explanation:

We are given that : g(x)=kf(x)      (1)

It means that f(x) and g(x) are proportional.

[Equation of direct variation: y=kx , where k= proportionality constant.]

From the given graph ,

At x= -3 , f(x)=1 and g(x) =-3

Put value of x=-3 in (1) , we get

g(-3)=kf(-3)  

\Rightarrow\ -3=k(1)  [∵ f(x)=1 and g(x) =-3]

\Rightarrow\ -3=k

i.e. The value of k = -3

Hence, the correct answer is -3.
