We are given the following information in the question:
Area of rectangular solar panel = 128 square cm
Width of panel = 20 cm
We have to find the length of the panel
Formula:
Hence, the length of rectangular panel is 6.4 cm.
This is an example of direct variation as greater would be length and breadth, the greater would be the area.
you would need to add the fraction
Answer:
Step-by-step explanation:
Let 
be an acute angle.
To solve: 
, we take the sine inverse of both sides to obtain:
Recall composition property of a function and its inverse function.
We apply this property to the left hand side to obtain;
We now use our scientific calculator to obtain;
We round to the nearest tenth to obtain;
Account balance = $389.42 + $389.42 (0.032) (7)
$389.42 + $87.23 = $ $476.65 (answer)
