Answer:
x=9 x=-1
Step-by-step explanation:
x²-8x-9=0 a=1 b=-8 c=-9
you have to use the quadratic formula to get the values.
Answer:
~96.6
Step-by-step explanation:
120/124 is 30/31 or 60/62 or 96.6/99.82
Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
Answer:
1
Step-by-step explanation:
anything raised to the power of 0 would equal 1 and p doesn't equal 1 here.
Answer:
A
Step-by-step explanation:
The inverses of functions are basically the Xs and Ys swapped. For example, the inverse of (2,-3) is (-3,2).
Thus, the inverse of (-2,4), (3,2), and (-6,10) will be (4,-2), (2,3), and (10,-6).
the answer is A.
