Answer:
cos(x=pi/4)= 
Step-by-step explanation:
Remember that 
We need to find cos(x) from the above equation.
cos(x)= 12) / 13. This solution is positive since cos(x) in the range (2pi/3, 2pi) is positive.
Now, to obtain cos(x+pi/4) lets use the relation for cos(a+b)= cos(a)*cos(b)-sin(a)*sin(b)
where a=x, b =pi/4
Hence
cos(x+pi/4) =cos(x)*cos(pi/4) - sin(x)*sin(pi/4)
cos(x+pi/4) = 
cos(x=pi/4)=
Solve the rational inequality by combining expressions and isolating the variable x
Answer:
the slide it's self is 10 feet long
Step-by-step explanation:
it says the height is 8ft off the ground which means that the slide being at a 45 degree angle it has to be at least 2 ft taller than the ladder
Here the right side of the 2 equations (which are different) both equal y
so 0 solutions
Even numbers on die: 2,4,6odd numbers on die: 1,3,5 3+3=6 -> 6 numbers in total3/6 chance because there are 3 even numbers. This would round to 1/2, so 1/2
