Answer:
exactly one
Step-by-step explanation:
The system of linear equations have:
one solution, infinitely many solutions or no solution.
One solution if the lines intersect.
Infinitely many solutions if the lines are the same (overlap)
There is no solution if the lines are parallel (they do not have a common point).
In the graph, two lines intersect. Therefore, the system of equations has one solution (0, 3).
Point C(0,3) is the y intercept because it's where x=0

Answer:
563.5 cm³
Step-by-step explanation:
Use the formula for the volume of a cone:
V = (1/3)πr²h
Recognize that the radius is half the diameter:
r = (11.9 cm)/2 = 5.95 cm
V = (1/3)π(5.95 cm)²(15.2 cm) ≈ 563.516 cm³
The volume of the cone is about 563.5 cm³.

<em>Additional comment</em>
If you use 3.14 for the value of π, then the result will be 563.2 cm³.

Answer:
arg (w)=π/4 and |w|=√2
Step-by-step explanation:
If z= x+iy is a complex number, then |z| is given by √ ( x²+y² ).
And the argument (z) is given by Ф = tan⁻¹ ( y/x ) where -π < x < π.
Now, in our case w= 1+i i.e. x=1 and y=1.
Therefore, arg (w) = tan⁻¹ (1/1) = π/4 and |w|=√ ( 1²+1² ) = √2 (Answer)
