Answer:
The Qn aint correct
it would make more sense if the figures invested where different
8% of 19k + 9% of 19k =1620
the figures are the same so even if we shifted the first 19k to the second side of 9% still it could make no sense(remain the same)
Answer:
(-8,-3)
Step-by-step explanation:
This question is similar to the vertex form of a quadratic equation, so you can think of this equation like f(x) = (x-h)+k. Using this equation, you can determine the vertex (h,k) of |x+8|-3, which is (-8,-3).
Answer: 
Step-by-step explanation:
For convenience, I labeled some points as shown in the attached picture.
Also, I assume
and
are tangents to the circle.
(reflexive property)
(tangents drawn from a common external point are congruent)
(right angles are congruent)
Therefore, we know
by HL.
Thus, by CPCTC,

This means the measure of minor arc AC is
, and thus 
P(8 or 12) = 1/6
P(not 8 or 12 = 5/6
Let the expected points fro one roll be X.

The answer is -(1/6) points.
