Answer:
hole at x=-3
Step-by-step explanation:
The hole is the discontinuity that exists after the fraction reduces. (Still doesn't exist for original of course)
The discontinuities for this expression is when the bottom is 0. x^2-9=0 when x=3 or x=-3 since squaring either and then subtracting 9 would lead to 0.
So anyways we have (x+3)/(x^2-9)
= (x+3)/((x-3)(x+3))
Now this equals 1/(x-3) with a hole at x=-3 since the x+3 factor was "cancelled" from the denominator.
Answer:
14
Step-by-step explanation:
.28 times 50 equals 14
Answer:
Step-by-step explanation:
11) Profit = Selling price - purchase price - other expenses

12) Profit = Selling price - purchase price - other expenses
(after rounding off)
13) Annual interest on bond
=INterest rate on face value of bond for 1 year

14)Cost of bond
= quoted value (rate)
=3500(80.5)
=2817.50
15) Cost of bond
= quoted value (rate)
=4250(83.5)
=3548.75
Answer:
yes, it is a right angle triangle
Step-by-step explanation:
If it is a right angle triangle, then sq(14) + sq48) = 2500 = sq(50)
(A) is your answer
In this case, only rotational symmetry can work, with a turn of 180°
hope this helps
