I think it's the first three.
-7.5 < -7
-4 < -3
-0.5 < -1
(those are the inequalities after i put each of the values for x in the original equation)

Step-by-step explanation:
Hello,
I do not see the full list of answers but I can say that 0 and 6 are the roots of this parabola
so
![h(x)=x(x-6)=x^2-6x](https://tex.z-dn.net/?f=h%28x%29%3Dx%28x-6%29%3Dx%5E2-6x)

Please see the attachments. For reasons I cannot fathom, the Brainly censor seems to think there are unapproved words contained in this text, so I cannot post it as text. Among other things, that means you probably will not be able to copy and paste the formulas into your spreadsheet—you will have to type them.
I apologize if you are offended by any of the words contained in this answer. I hope you will take them in the intended context—a math problem about the use of Excel.
Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is the radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
![A=\pi \times (11)^2\\\\A=380.13\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Ctimes%20%2811%29%5E2%5C%5C%5C%5CA%3D380.13%5C%20cm%5E2)
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
![A=\pi \times (15)^2\\\\A=706.85\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Ctimes%20%2815%29%5E2%5C%5C%5C%5CA%3D706.85%5C%20cm%5E2)
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
![A=\pi \times (2)^2\\\\A=12.56\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20%5Ctimes%20%282%29%5E2%5C%5C%5C%5CA%3D12.56%5C%20cm%5E2)
So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.
Answer:
<A = 16.82 degrees
Step-by-step explanation:
Tan^-1 = opposite/adjacent
Tan^-1 (13/43) = 16.82 degrees
