1 inch = 48 miles. Therefore, 2.5 inches = 2.5X48= 120miles
First, change 2/5 into a decimal by dividing 2 by 5. Decimal= .4. Now move the decimal 2 places to the right to find percentage. Answer is 40%
F(x) = -7x + 5x² + 10
x = -2
substitute the x by its value
f(-2) = -7(-2) + 5(-2)² + 10
f(-2) = 14 + 5(4) + 10
f(-2) = 14 + 20 + 10
f(-2) = 44
to convert to radians multiply by *2pi/360
330 * 2pi/360
330/360 * 2pi
33/36 *2pi
11/12 *2pi
11/6 * pi
Answer: 11/6 *pi
