Answer:
see explanation
Step-by-step explanation:
To calculate the first 3 terms substitute n = 1, 2, 3 into the n th term formula
(a)
8 - 1 = 7
8 - 2 = 6
8 - 3 = 5
The first 3 terms are 7, 6, 5
(b)
The first negative term wii occur when n > 8, that is n = 9, thus
8 - 9 = - 1 ← first negative term
Answer:
A. 12
Step-by-step explanation:
Selecting B, C, or D would create a difference of perfect squares since each of these numbers are perfect squares. Additional factoring would then be needed.

But selecting 12 gives
which cannot be factored. It is factored completely.
Answer:
Complementt angle = 44°
Step-by-step explanation:
Given:
One angle = 46°
Find:
Complementt angle
Computation:
In complement angle
∠A + ∠B = 90°
46° + ∠B = 90°
∠B = 90° - 46°
∠B = 44°
Complementt angle = 44°
Answer:
B. 36
Step-by-step explanation:
The answer is B. 36.
Answer:
between x=-1.5 and x = 0
between x = 0 and x = 1.5
Step-by-step explanation:
For the interval -1.5 < x < 1.5, we can see that the slope is negative (i.e from top left to bottom right). Hence it can be said that the graph is decreasing during this interval.
For the other parts of the graph (as shown) the slope is positive (i.e from bottom left to top right). in those areas, the graph is increasing.
