Transcript text: 19. A group of cells grows in number as described by the equation $y=16(2)^{t}$, where $t$ represents the number of days and $y$ represents the number of cells. According to this formula, how many cells will be in the group at the end of the first 5 days?
A. 80
B. 160
C. 400
D. 512
E. 1,280
Solution
Solution Steps
To find the number of cells at the end of the first 5 days, substitute \( t = 5 \) into the given equation \( y = 16(2)^t \). This will give the number of cells after 5 days.
Step 1: Substitute \( t \) into the Equation
To find the number of cells after 5 days, we substitute \( t = 5 \) into the equation \( y = 16(2)^t \):
\[
y = 16(2)^5
\]
Step 2: Calculate \( 2^5 \)
Next, we calculate \( 2^5 \):
\[
2^5 = 32
\]
Step 3: Multiply by 16
Now, we multiply the result by 16:
\[
y = 16 \times 32 = 512
\]
Final Answer
The number of cells in the group at the end of the first 5 days is \\(\boxed{512}\\).
