For this case we have an exponential equation of the form:
Where,
- <em>A: initial value
</em>
- <em>b: decrease rate
</em>
- <em>x: number of years
</em>
Substituting values in the given equation we have:
Answer:

Answer:
(- 3, 5 ) & (-2,7)
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , thus
(5, 3 ) → (- 3, 5 )
Under a counterclockwise rotation about the origin of 90.
a point (x, y ) → (- y, x ) , thus
(7, -2 ) → (-2, 7)
Answer:
neither
Step-by-step explanation:
<em>Both statements are correct.</em>
If matrix 1 has dimensions (r1, c1) and matrix 2 has dimensions (r2, c2), their product can be formed if c1 = r2. The resulting product matrix will have dimensions (r1, c2).
Answer:
6. B
7. D
Step-by-step explanation:
For 6 found that the 56 pieces in the first bag was about 18% of that bag. So then I found that 18% of 450 is ruffly 84, so B
For 7 I multiplied 5x5 is 25 so then 50x5 is 250, which is D
