Cal's dog weighs approximately 94 pounds.
Step-by-step explanation:
We have y = sin(ax + b).
=> dy/dx = a * cos(ax + b)
=> d²y/dx² = a[a * -sin(ax + b)] = a² - a * sin(ax + b).
Therefore d²y/dx² = a² - ay,
d²y/dx² - a² + ay = 0.

Simplify
Express 20 as 4 * 5
Split
This gives:
Express as 100 * 3
This gives:
Express as 64 * 2

It’s C. Since that’s the middle based on the diagram
Count change of signs to tell positive roots
then replace x with -x and evaluate, then count change in sign for negative roots
initially
+, -, -, +, +, -
3 changes
3 or 1 positive roots
replacing x with -x
-,-,+,+,-,-
2 changes
2 or 0 negative roots
B is answer
