10 x 3 x 2 = the volume
10 x 3 = 30
30 x 2 = 60 cm^3
it is cm^3 because all of the numbers you have are in cm
1.) Let the distance of the person from the boat be x, then
sin 65 = 15/h
h = 15 / sin 65 = 16.55 ft
2.) No triangle shown
3.) Let the angle of elevation of the sun be x, then
tan x = 35 / 50 = 0.7
x = arctan (0.7) = 34.99
To solve this, you need to subtract 28 from both sides, then solve.
y=x^2+3x-28
The x-intercepts are (-7,0) and (4,0)
If you multiply decimals , the estimate value is necessary !
it could be understood easily, if at any place the number exceeds 4 , then the value in front is raised by one !
as;
2.234 = 2.23 , it will remain same but,
2.235 = 2.24 the 3 raised to 5 !!
if you have any problem yet , comment !!
So it would be 12 minutes and $5 per 12 minutes.
