Answer:
3,12,21
Step-by-step explanation:
You add 9 to the number each time so the next 3 terms will be....
-6+9 =3
3+9=12
12+9=21
Vertex: (-4,-3)
Focus: (-4, -11/4)
Directrix: y= -13/4
Answer:
Option (D) is correct.
Step-by-step explanation:
We know that exponential decline in Math can be termed as a consistent reduction of an amount by percentage over a certain period of time.
It can be expressed using the formula
y = a (1-b)ˣ
here
- y represents the final amount
- a represents the original amount
- b represents the decay factor
- x represents the amount that has passed
Now, map our problem using the same concept formula
as
3000 students were enrolled, so
as High School has been experiencing an annual decline of 2.2% in enrollment, so
so substituting b = 0.022 and a = 3000
y = a (1-b)ˣ
y = 3000 (1 - 0.022)ˣ
as
so the expression becomes
y = 3000 (0.978)ˣ
Therefore, option (D) is correct.
