=4n - 1
Since the sequence is add 4 and 3-4 = -1
20 x 4n = 80-1 = 79
Yes, this question is statistical because the temperature in North Carolina is a number based of temp which makes it a statistical number.
Answer:
f(x) = -3x
--->#6
f(x) = |x-1|+3
--->#5
f(x) = √(x+3)
--->#3
1/2x²
--->#1
f(x) = (x+1)²-3
--->#4
4|x|--->#2
Step-by-step explanation:
Recall for transformations:
- Adding a number outside the function moves it up
- Subtracting a number outside the function moves it down
- Adding inside the function moves it to the left
- Subtracting inside the function moves it to the right
- Multiplying to the function by a number less than 1 compresses
- Multiplying to a function by a number greater than 1 stretched it
- Multiplying by a negative flips the graph
f(x) = -3x
This is multiplication by a number greater than 1 and a negative so this stretches and flip. This is #6, a reflection.
f(x) = |x-1|+3
Subtraction inside the function shifts it to the right 1 and addition outside shifts it up 3. This is #5.
f(x) = √(x+3)
Addition inside the function shifts it to the left 3. This is #3
1/2x²
Multiplication by 1/2 which is less than 1 compresses it. This is #1.
f(x) = (x+1)²-3
Addition inside the function shifts the function to the left once. This is #4.
4|x|
Multiplying by 4, a number greater than 1, stretches it. This is #2.
Answer:
the amount that should be worth in 25 years is $2,155,770
Step-by-step explanation:
The computation of the amount that should be worth in 25 years is shown below:
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $250,000 × (1 + 0.09)^25
= $250,000 × 1.09^25
= $2,155,770
Hence, the amount that should be worth in 25 years is $2,155,770
