Write using exponents.
4.4.4.a. b.a. b.

4^3 x a^2 x a^2

Step-by-step explanation:

This should be done with the understanding of exponents. y x y would be y^2 because it is multiplying itself. Now use this for you question.

there are 3 4's so.. it would be 4^3

There are 2 a's so it would be a^2

There are 2 b's so it would be a^2

TACK ON THE MULTIPLICATION SIGNS TO GET:

4^3 x a^2 x a^2

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
