Answer:
B: Ellipse
Step-by-step explanation:
Just put in the equation on desmos. An ellipse will pop-up
The conic section is represented by the following equation –5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0 is circle.
We have given that the equation of the equation is,
–5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0
What is the general formula of the ellipse?The general formula of the circle is
[tex]ax^2+2xy+by^2+2fx+2gy+c=0[/tex]
Compare the given equation with the general formula of the circle so we get the equation of the circle
Therefore the equation of the circle is –5^+ 9xy + 5y^2 + 6x – 4y + 11 = 0

the two lines below are parallel if the slope of the red line is 5 what is the slope of the green line
Answer:
5
Step-by-step explanation:
Since the two lines are parallel, they must have the same slope. This means that the slope of green line must be 5 just like the red line. You can also use the slope formula (rise/run) or change in y divided by change in x.

Find (g o f)(-1). *
f(x) = x2 + 2x – 3
g(x) = x - 5
O A. -11
OB.-4
Oc.o
O D.-9
Answer:
D -9
Step-by-step explanation:
(g o f)(-1) = g(f(-1))
f(-1) = [tex]f(-1) = (-1)^{2} + 2(-1) - 3\\= 1 - 2 - 3\\= -4[/tex]
g(-4) = -4 - 5 = -9
So, (g o f)(-1) = -9

18.1
17.3
15.9
16.4
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
[tex]a^{2} +b^{2}= c^{2}[/tex]
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
[tex]10^2+b^{2} =20^{2}[/tex]
Then, use the squares in the equation:
[tex]100+b^{2} =400[/tex]
Then, subtract 100 from both sides to isolate b:
[tex]b^{2} =300[/tex]
Finally, square root both sides to get your answer:
[tex]b=17.3205080757[/tex]
Then round to the nearest tenth which gives you 17.3.

8.6 x10^-9 in standard form
-9 in power means that the value is in fractional and the 10 base is multipied 9 times and put it on denominator.
8.6 = 86 x 10^-1
Let's multiply :
86 x 10^-1 x 10^-9
= 86 x 10^-10
= 86/10000000000
=0,0000000086
Note : if you don't know about how 10^-1 x 10^-9 returns 10^-10, it's because of exponential rules. If the base are same wuth each other, then just do the addition operation in the exponent like this :
10^(-1+(-9))
= 10^(-1-9)
=10^-10
