Answer:
All the options are correct.
Step-by-step explanation:
Holly begins with 1 penny in her piggy bank. She adds 2 pennies on day 1, 4 pennies on day 2, and 8 pennies on day 3. She continues this pattern for 30 days.
The pattern which she choses is where n denotes the number of days.
A)
The graph of this sequence would pass the vertical line test.
" Vertical line test: A function can only have one output, y, for each unique input, x " .
Here also y=2^n and x=n.
B)
Each day corresponds to a unique amount of pennies in this sequence.
Since the sequence is increasing, hence option B is correct.
C)
The graph of this sequence would pass the horizontal line test.
A test use to determine if a function is one-to-one.
As for each n we get a unique value.
Hence, option C is correct.
D)
Each amount of pennies corresponds to a unique day in this sequence.
This option is also true as each amount is a function of number of days.
Hi there!
v = ±
- - - - - - - - -
K = 1/2mv²
Isolate for the variable "v". We can begin by dividing both sides by 1/2. (Multiply by the reciprocal, or 2):
2 · K = 2 · (1/2mv²)
2K = mv²
Continue isolating by dividing both sides by "m":
2K / m = v²
Take the square root of both sides. Remember that the solution can either be positive or negative since there are positive and negative roots.
v = ±
