Answer:
f(3) = 18
Step-by-step explanation:
f(x) = 2x^2
Let x = 3
f(3) = 2 * 3^2
= 2 *9
= 18
opposite side of an angle
hypotenuse
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
5
Use the distance formula
d=
