Answer:
25
Step-by-step explanation:
The new price, $45, can be expressed as a percentage of $60 by taking it as a fraction of $60, converting to a decimal value, and multiplying by 100%. $45/$60=3/4=0.75, 0.75x100%=75%. So since 100%-75%=25%, the value was reduced by 25%.
Convert from degrees to radians using the ratio
π/180. 3aπ/2 radians
is this what you need?
or 90 degress
The answer should be 0.5x^4+12.5
