Answer:
The value of r is 0.451
The percentage decrease is about 45.1%
Step-by-step explanation:
The given exponential function is
Using the exponent rule,
Now the value of
Thus, we can rewrite the function as
Therefore, the function in form
The value of r is 0.451
The percentage decrease is about 0.451 ×100 = 45.1%
Answer:
its going 300 miles per hour
Step-by-step explanation:
Volume = πr²h/3
Here, V = 500
h = 16
Substitute their values,
500 = r² * 22/7 * 16/3
500 = r² * 352/21
r² = 500*21 / 353
r² = 10500 / 353
r² = 29.74
r = √29.74
r = 5.45
Now, diameter = 2 * radius = 2 * 5.45 = 10.90 cm
So, Your Final Answer would be 10.90 cm
Hope this helps!
