Answer:
The African elephant weighs <u>111.5 tons</u> less than a blue whale.
Step-by-step explanation:
Given:
Animal Weight(pounds)
African Elephant 15,000
Blue Whale 238,000
Now, to find the weight of how more tons does a blue whale weigh than an African elephant.
As given, 1 ton = 2,000 pounds.
So, to convert the weight from pound to tons by dividing:
African elephant 
Blue whale 
Now, to get the weight of how more tons is blue whale weigh than an African elephant we subtract:



Therefore, the African elephant weighs 111.5 tons less than a blue whale.
Answer:
Alright so basically
Step-by-step explanation:
Answer:
The equation that represents the motion of the string is given by:
.....[1] where t represents the time in second.
Given that: A = 0.6 cm (distance above its resting position) , k = 1.8(damping constant) and frequency(f) = 105 cycles per second.
Substitute the given values in [1] we get;
or
(a)
The trigonometric function that models the motion of the string is given by:

(b)
Determine the amount of time t that it takes the string to be damped so that 
Using graphing calculator for the equation
let x = t (time in sec)
Graph as shown below in the attachment:
we get:
the amount of time t that it takes the string to be damped so that
is, 0.5 sec
