cos a= √(1-sin²a)
= √(1-16/25)
= √(9/25)
= 3/5
sin b=5/13
cos b= √(1-sin²b)
= √(1-25/169)
= √(144/169)
= 12/13
sin(a+b)= sin a· cos b + cos a · sin b
= 4/5· 12/13 + 3/5· 5/13
= 48/65+15/65
= 63/65

Tan(pi/6) = 1/3 √3
The exact value of tan (π/6) is 1/√3.
Given a trigonometric function,
tan (π/6)
We have to find the exact value of the given function.
We know that, the value of π/6 in degrees is 30 degrees.
So here, we have to find the value of tangent function of 30 degrees.
We know that,
Tan (x) = sin (x) / cos (x)
Here x = π/6
Tan (π/6) = sin (π/6) / cos (π/6)
= (1/2) / (√3 / 2)
= 1/√3
Hence the tan (π/6) is 1/√3.

The probability of randomly drawing a penny is 6/24 or 1/4, since there are 6 pennies out of a total of 24 coins.
How to solve and What is Probability?
The probability of randomly drawing a quarter is 10/24 or 5/12, since there are 10 quarters out of a total of 24 coins. The probability of randomly drawing a coin that is not a penny is 18/24 or 3/4, since there are 18 coins that are not pennies out of a total of 24 coins.
Probability is the branch of mathematics that deals with measuring the likelihood or chance of an event or outcome occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
Probability theory is used to make predictions and informed decisions based on available data in various fields, including statistics, finance, engineering, and science.
It involves understanding and analyzing random events, and determining the likelihood of specific outcomes. Probability is an essential tool for decision-making in various applications, such as risk analysis, game theory, and quality control.

Answer:
The output value of f(-2) is, 14
Step-by-step explanation:
Given the function:
......[1]
We have to find the output of f(-2).
Substitute x = -2 in [1] we have;
⇒
Simplify:
therefore, the output value of f(-2) is, 12
f(-2) = 4 - (-6) + 2
f(-2) = 10 + 2
f(-2) = 12
2) 4x+6y=24 4x-y=10
3)2x-y=-3 x+3y=16
4) 2x+3y=7 3x+4y=10
Answers
First of all we have add both equation but to be sure that the value we want to eliminate are both in a way that would make it possible t be deleted.
3x+y=-1
5x-y= 9
8x = 8
x= 1
In this case we are able to eliminate y becuase if we add +y-y we get that our answer is 0. and 3x + 5x would be 8x and -1+9 would be equal to 8 and to find x we needed to divided giving us that the answer for x is 1 becuase 8/8 is 1.
Then to find y we substitude the value of x in any of the formulas.
3(1)+y= -1
3+y= -1
y= -1-3
y=-4
When we have our y value we can determine if it is correct by replace the values.
5(1)--4= 9
5+4= 9
9=9
Up until now we are fine. So we do the same with the other equation.
3(1)+-4=-1
3+-4=-1
-1=-1
So by this we can now detemine that.
x= 1
y= -4
2) 4x+6y=24 4x-y=10
4x+ 6y =24
4x-y=10 (*-1)
4x+6y=24
-4x+y=-10
7y= 14
y= 14/7
y= 2
In this case we are not able to delete any of the variables so we multiplied by -1 to be able to eliminate x.
Then to find x we substitute the value of y in any of the formulas.
4x-2=10
4x= 10+2
x= 12/4
x= 3
So we now know our variables so we substituted them to see if they are correct.
4(3)+6(2)=24
12+12=24
24=24
We do the same with the other equation.
4(3)-2=10
12-2 =10
10= 10
So we can assume that.
x= 3
y= 2
3)2x-y=-3 x+3y=16
(3*)2x- y= -3
x+ 3y = 16
6x -3y = -9
x+3y =16
7x= 7
x= 1
In this case we are not able to delete any of the variables so we multiplied by 3 to be able to eliminate y.
Then to find y we substitute the value of x in any of the formulas.
1+ 3y = 16
3y= 16-1
y= 15/3
y= 5
So we now know our variables so we substituted them to see if they are correct.
2(1)- 5 =-3
2-5= -3
-3= -3
We do the same with the other equation.
1+3(5)= 16
1+15=16
16=16
So we now are sure that
x= 1
y= 5
4) 2x+3y=7 3x+4y=10
2x+3y =7 ( * - 4)
3x+4y =10 ( * 3)
-8x -12y = -28
9x +12y = 30
x= 2
In this case we are not able to delete any of the variables so we multiplied one of teh quations by - 4 to be able to subtract in our sum and the other by 3 to have the same number on y to be able to eliminate y.
Then to find y we substitute the value of x in any of the formulas.
2(2)+3y= 7
4+3y=7
3y= 7-4
y= 3/3
y= 1
So we now know our variables so we substituted them to see if they are correct.
3(2)+4(1)= 10
6+4=10
10=10
We do the same for the other
2(2)+3(1)=7
4+3= 7
7=7
So with that we can say that.
x= 2
y= 1
