Answer: Average change in sea lion's altitude per minute is 90.05 meters per minute.
Explanation:
Since we have given that
Height at which a sea lion dove from the water surface at sea level = (-)216.12 meters
We'll neglect the negative sign while finding the value of average rate of change.
Time taken to reach the above altitude = 2.4 minutes
So, Average change in the sea lions altitude per minute is given by

Hence, average change in sea lion's altitude per minute is 90.05 meters per minute.
Answer:
18 = m
Step-by-step explanation:
2=m/2-7
Add 7 to each side
2+7=m/2 - 7+7
9 = m/2
Multiply each side by 2
9*2 = m/2 * 2
18 = m
Answer:
After 5 weeks.
Step-by-step explanation:
Westley starts with $85 and saves $5 per week. So:

Buttercup starts with $10 and saves $20 per week. So:

When they have the same amount of money, the two equations will be equal to each other. Therefore:

Solve for x. Subtract 10 from both sides:

Subtract 5x from both sides:

Divide both sides by 15:

Westley and Buttercup will have the same amount of money after 5 weeks.
Answer:
141, meaning that there will be two real solutions
Step-by-step explanation:
The discriminant of a quadratic is
, which in this case is:

Since the discriminant is positive and not zero, there will be two real solutions to this equation. This is because when the discriminant is negative, and you take the square root of it, you get a negative number. If you take the square root of 0, you get 0, which means that there will only be one solution to the equation.
Hope this helps!
