Answer:
positive
Step-by-step explanation:
the discriminant of the function is postive.
because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0
that implies the discriminant is positive.
if we have 2 distinct real solution
if we have no real solution but 2 complex solutions
if we have 2 identical real solution
<h3><u>Answer :- </u></h3>
- The total surfAce area of cone is <u>1244.57m².</u>
<u>To </u><u>find </u><u>:</u><u>-</u><u> </u>
- The total surface area of cone..
Given that ,
- The slant height of the cone = 21m.
- Diameter of it's base = 24m.
<u>=</u>> Diameter / 2
=> 24 / 2
=> 12m
<h3>As we know that , </h3><u>Total surface area of cone = πr ( r + L ) .</u>
<h3><u>Where</u><u> </u><u>we </u><u>know</u><u>,</u></h3>- π = 22/7
- r = Radius ( radii )..
- L = Slant height.
The total surface of cone is,
<u>=> Total surface area = πr { r + L } ..</u>
• Therefore , The total surface area of cone is <u>1244.57m².</u>
Hope this helps you :)
