Answer:
Step-by-step explanation:
lets say in the shown triangle x=165
so speed 
and 
Also since distance = speed* time
time = pi minutes = pi/60 seconds
y = 
y = 
Now using the pythagorean :

<u>derivate the equation so we get :</u>


m/s
So Rate of change = <u><em>25.387 m/s</em></u>
Answer: $284.80
look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:
1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%
2nd. Next, you do 0.40 x 712.00 = or
712.00
x 0.40
______
$284.80
Answer: hello your question is vague hence i will provide a more general answer
Area of a right angled triangle = 1/2 * b * h
Step-by-step explanation:
For a right- angled triangle; the sum of squares of the opposite and adjacent sides = square of the longest side ( i.e. hypothenuse )
hence the Area of a right angled triangle = 1/2 * b * h
where : b = adjacent , h = opposite side
