Answer:
Option C. negative
Step-by-step explanation:
we know that
In a quadratic equation of the form
The discriminant is equal to
If D=0 ----> then the system has only one real solution
If D > 0 ---> the the system has two real solutions
If D < 0 ---> then the system has complex solutions
The quadratic equation of the graph has complex solutions
therefore
The discriminant is negative
Solving for x
Since x<span> is on the right hand side of the </span>equation<span> switch the sides so it is on the left hand side of the </span>equation<span>.
</span><span>2x+yi=−14−3i

The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.
<h3>What is volume?</h3>
Volume is the capacity of an object.
To calculate the surface area and volume of the cone shown above, we use equation 1 and equation 2 respectively.
Formula:
- S = πr√(r²+h²)............. Equation 1
- V = πr²h.................. Equation 2
Where:
- S = Surface area of the cone
- V = Volume of the cone
- r = Radius of the base of thye cone
- h = Vertical height of the cone.
From the diagram,
Given:
- r = 10 km
- h = 24 km
- π = 3.14
Substitute these values into equation 1 and equation 2 respectively.
- S = 3.14×10[√(24²+10²)
- S = 31.4(√676)
- S = 31.4×26
- S = 816.4 km²
Also for the volume of tyhe cone
- V = 3.14×10²×24
- V = 7536 km³
Hence, The surface area and the volume of the cone is 816.4 km² and 7536 km³ respectively.

Answer: No
Step-by-step explanation: While he is partly correct, it is not impossible. The odds are 1 in 6, but just because he already rolled it once, doesn’t mean he cannot do it again.
