Radio signals travel at a rate of 3x10^8 meters per second. how many seconds would it take for a radio for a signal to travel from a satellite to the surface of earth if the satellite is orbiting at a height of 4.2x10^7 meters? (hint: time is distance divided by rate.) a. 1.26x10^16 seconds b. 1.26x10^15 seconds c. 1.4x10^1 seconds d. 1.4x10^-1 seconds

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

the first one, all those points on the line just make a strait line.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
