A submarine can descend at a rate of -2.5 meters/second. Suppose that the submarine begins at a depth of -25 meters. How long would it take the submarine to reach its maximum depth of -200 meters?_________________
Answers
abs (-200- (-25))= 175 m (distance is always >=0, so we have to take the abs).
175 m* (1 sec/ 2.5m)= 70 sec.
It would take the submarine 70 seconds to reach its maximum depth.
Hope this helps~

Given : Number
To find : What is the standard form of this number ?
Solution :
We know that, The number given is in scientific form in which "e" represents the number of zeroes placed as decimal to the right.
So,
In standard form,
Therefore, The standard form is
The number in scientific notation can be written in standard form as 0.00000146
In scientific notation, a number is expressed as the product of a decimal number (between 1 and 10) and a power of 10.
In this case, can be interpreted as follows:
1.46 is the decimal number, which is between 1 and 10.
e-6 indicates that we need to multiply 1.46 by 10 raised to the power of -6.
To convert it to standard form, perform the multiplication.
10 raised to the power of -6 is equal to 0.000001.
So, multiplying 1.46 by 0.000001 gives us 0.00000146.
Therefore, the standard form of the number is 0.00000146.
