The scuba diver's position relative to sea level after the 4.6 minutes is 5.1 ft.
Given:
A scuba diver descends in the water at a rate of 23 1/2 feet per minute for 2.6 minutes.
A scuba diver ascends at a rate of 28 feet per minute for 2 minutes after seeing a big fish.
To find :
The scuba diver's position relative to sea level after the 4.6 minutes.
Solution:
Rate of a scuba diver descending in the water for 2.6 minutes = 
Distance covered by a scuba diver in 2.6 minutes = 
Rate of a scuba diver ascending for 2 minutes = 
Distance covered by a scuba diver in 2 minutes = 
The position of scuba diver after 4.6 minutes relative to sea level:
The scuba diver's position relative to sea level after the 4.6 minutes is 5.1ft.

The amount for the deposit is $25350, monthly payment is $1436.5 and the total amount that Sipho pays is $178492.
Given price of car $169000, deposit of 15%, monthly installments being 1% of left over price and number of years be 9 years.
We have to find the amount of deposit, monthly installments and the total amount paid by Sipho.
We have been told that deposit is 15% of total amount. So the deposit will be 15%*169000=$25350.
Monthly installment is 1% of the left over amount.
left amount=169000-25350=$143650.
Monthly installment being =143650*1/100
=$1436.5
Total amount paid by Sipho=deposit +installment amount * numberof installments
Number of installments=12*9
=108
Total amount=25350+1436.5*108
=25350+155142
=$178492
Hence deposit is $25350, monthly payment being $1436.5, total amount be $178492.

Explanation:
Imagine we have a point
P
with Rectangular (also called Cartesian) coordinates
(
x
,
y
)
and Polar coordinates
(
r
,
θ
)
.
The following diagram will help us visualise the situation better:

We can see that a right triangle is formed with sides
x
,
y
and
r
, as well as an angle
θ
.
We have to find the relation between the Cartesian and Polar coordinates, respectively.
By Pythagora's theorem, we get the result
r

=
x

+
y

The only properties we can say about
θ
are its trigonometric functions:

r
