Answer:

It is a type of conic section, but there is only one point .

This represent a single point (0, 0)  in the real plane.

This is a complex graph x = i*y  - y,   there are imaginary numbers.

Step-by-step explanation:

2 xx + 4xy +  4yy = 0

...xx + 2xy + y*y  + yy = 0

(x + y)^2  + yy = 0

if  x is a constant

then the cross sections would be parabolas in the zy-plane

... 2yy + 4xy  - 2xy  + xx = 0

(2yy + 4xy + 2xx -2xx) - 2xy + xx = 0

2(y + x)^2 - 2xx - 2xy + xx = 0

2(y + x)^2 - xx - 2xy  = 0

2(y + x)^2 - xx - 2xy  +yy  - yy = 0

...

(x + y)^2  + yy = 0

x = i*y  - y

if  x = r cos a

y = r sin a

cos a )^2  + cos a sina  + sin a)^2  +  sin a)^2 = 0

cos a sin a + sin a)^2 = -1

A​ self-tanning lotion advertises that a 4 ​-oz bottle will provide seven applications. Jen found a great deal on a 13 ​-oz bott
Rainbow [258]

Answer:

22.75 applications

Step-by-step explanation:

From the above question, we understand that:

4 ​-oz bottle = 7 applications

13 ​-oz bottle = x applications

Cross Multiply

4 -oz bottle × x applications = 13 -oz bottle × 7 applications

x applications = 13 -oz bottle × 7 applications/4 -oz bottle

x applications = 22.75 applications

Therefore, the number of applications of the 13 -oz bottle​ self-tanner that should Jen​ expect is 22.75 applications.

How would you describe the difference between the graphs of f(x) = x^2 +4 and<br> g(y) - y^2 +4?
s2008m [1.1K]

Answer:

Step-by-step explanation:

The function f(x)=x^2+4 is a positive upwards opening parabola with the vertex at (0, 4), whereas

the function g(y)=y^2+4 is a positive rightwards opening parabola (sideways parabola) with the vertex at (4, 0). This means that answer to this is that g(y) is reflected over the x axis whereas f(x) is reflected over the y axis.

Write the mixed number as a fraction 4 1/3, 1 2/5, 3 2/3
nasty-shy [4]
To get they total number of the fraction, you first times the bottom,  by the number one the side of the mixed number, and then add the top number to the answer. so for the first one, 3*4 = 12 + 1 = 13 so the answer is 13/3, for the next one, 5*1 = 5 + 2 = 7, so the answer is 7/5, and for the last one, 3*3 = 9 + 2 = 11, so the answer is 11/3                                                                                      so if your to lazy to read this the answers are                                                        1. 13/3                                                                                                                2. 7/5                                                                                                                  3. 11/3
