What is the exact value of tangent (negative StartFraction pi Over 3 EndFraction)

Mathematics

ExtremeBDS [4]3 years ago

Answer:

tan(-π/3) =  -1.732050808

Step-by-step explanation:

Given in the question, we have to find the value of tan(-pi/3) or it can be written as:

x = tan(-\frac{\pi}{3})

where x is the exact value of the given tangent.

However, in this question, one may get confused and put the value of π = 3.14, which is wrong. The value given is in radians, which is used to measure angles, just like degrees.

To make it easier, lets convert the radians into degrees. We know that

π = 180°

-π/3 = -180/3 = -60°

Find x:

x = tan (-60°)

x = -1.732050808

Solve the system x+3=22 2x-y=2
steposvetlana [31]

Hello from MrBillDoesMath!

Answer:

x = 19, y = 36

Discussion:

x + 3 = 22     (*)

2x - y = 2      (**)


Subtract 3 from both sides of (*)

x + 3 -3 = 22 = 3 = 19  =>

x = 19


Substitute x= 19 in (**)

2(19) - y = 2 =>

38 - y = 2 =>           (add y to both sides)

38 -y + y = 2 + y =>

38 = 2 + y  =>         (subtract 2 from both sides)

38 -2 = 2 -2 + y =>

36 = y

Eli and Karl each throw a basketball straight up in the air at the same time. Eli is standing on a deck and the height of his ba
tino4ka555 [31]
We are to find the time at which the height of basketball thrown by Eli and Karl is equal. We have the functions which model the heights of both basketballs. So by equating the functions representing the height of both basketballs we can find the value of x from that equation at which the height is same for both basketballs.

-4.9 x^{2} +12x+2.5=-4.9 x^{2} +14x \\  \\ 
12x+2.5=14x \\  \\ 
2.5=2x \\  \\ 
x=1.25

Thus after 1.25 seconds the height of basketballs thrown by Eli and Karl will be at the same height. This can be verified by finding the heights of both at x=1.25

For Eli:
Height=f(1.25)=-4.9 (1.25)^{2}+12(1.25)+2.5=9.84375

For Karl:
Height=f(1.25)=-4.9 (1.25)^{2}+14(1.25)=9.84375

Thus height of both basketball is equal after 1.25 seconds
