Answer:
Step-by-step explanation:
Given
Rotation: 90 degrees clockwise
Required
Determine A'B'C'
When a point 
is rotated 90 degrees in the clockwise direction, the new coordinates is: 
So, we have:
Becomes
(predicted value - exact value)/exact value * 100
(31 - 34)/34 * 100 = 8.8%
The probability of an event is given by the number of favorable outcomes divided by the total number of outcomes. Here the event is the alarm clock running out of power. There are 24 hours during which the power can go out. You are asleep during 8 of these. A "favorable" outcome in this case is the power going out while you are sleeping -- that is, during one of those 8 hours. This makes the probability that the power goes out while you are sleeping 8/24.
If you would like to find the value of a in the polynomial, you can do this using the following steps:
(y - 4)(y^2 + 4y + 16) = y^3 + 4y^2 + 16y - 4y^2 - 16y - 64 = y^3 + 4y^2 + ay - 4y^2 - ay - 64
a = 16
The correct result would be 16.
