you distribute and then combine like terms. x=4 :))
Answer:
f = 2
Explanation:
g(x) = cos(x/2) - 3x=w where w=-3.5 or -1 or -38.5
13– (13/2)-3*13=-3.5 (1st d value of g(x))
-1-(-1/2)-3*(-1)=-1 (the 2nd possible value)
g(x) = cos(x/2) - 3x=-1 where the first x=13 and the 2nd one=-1
where the first x=-1 and the 2nd one=-38.5 (the 3rd value)
g(x) = cos(x/2) - 3x)=0 where cos(x/2=-3.5
g(f(x)) = cos(f(x)/2) - 3 aka 0.5 f(x) = cos(2x+5 aka 7x) (x/2 - 3 =aka -1 );
(2x+5) = 7x by definition but the equation has to be set to 7 to find x)
(7x/2 -6x=0) -7 on both sides
x/2–6x=-7
x/2= 13
26/2=x
x=13 (these values are set up for 2x+5=7.
13-(-7)=-7
13-6+-1=-7
the 2nd x=-1
gfx=cos*2*x i.e cos*2*13 or cos*2*-1
cos*2*13=26
cos*2*(-1)=-1
cos=1
(cos*2*13)=the 1st gfx value=26 basically.
( cos*2*(-13)=-26 (the 2nd gfx value)
cos*2*(-1)=-`1 (the 3rd gfx value)
f=2
hope this helped!
Answer:
The answer to this question is given in the explanation section.
Explanation:
C# uses the struct keyword to declare structure.
The are used to store related data item.
For example the record of Student i-e his name, father name, address and class no can be declared using structure
using system
struct Student {
public string name;
public string father_name;
public string address;
public int class_no;
};
The fact that an electric spark in the presence of air between two carbon rods is capable of producing a very bright light still baffles many. These two carbon rods must have a gap of the right size in between for effective lighting. The bigger the gap, the more the flicker. This phenomenon is what is referred to as Electric “arc” lighting. The arc light was invented by Humphry Davy in the first decade of the 1800s. It was the first practical electric light that was widely used as a source for streets, theaters, and large building lighting.
