+62 "OK, so like the question that i need is "The altitude "a" (in feet) of a plane "t" minutes after liftoff is given by a=3400t+600. How many minutes afterliftoff is the plane at an altitude of 21,000 feet?" Sorry, i didn't put it right earlier."
Maybe you should have put that in the question.
We want to know the number of minutes and we have the value of a, 21,000. Plug in values:
21,000 = 3,400t + 600
20,400 = 3,400t
t = 6
So, it would take \(\boxed{6}\) minutes to achieve an altitude of 21,000 feet.
+80 Um, I guess a is the total, and 3400t is the amount per time, and we have a starting base at 600...
+36915 You really can't solve ONE equation with TWO variables without more information.....like another equation relating the two variables...OR a value for one of the variables (a or t)
As written there are infinite answers,,,,,
I'm sorry, but math isn't really my "thing" so i have no idea what you mean. May you please say it a little more to where a teenage girl can understand please?
+36915 Sorry..... You have ONE equation a = 3400t + 600
and TWO variables a and t
you cannot solve this equation unless you are given a or t OR you have another equation which involves a and t
say a= 12 t or something like that.....
OK, so like the question that i need is "The altitude "a" (in feet) of a plane "t" minutes after liftoff is given by a=3400t+600. How many minutes afterliftoff is the plane at an altitude of 21,000 feet?" Sorry, i didn't put it right earlier.
+36915 Heck yah! There ya go.... we needed the 'a' 21000 ft TwentyFour posted the solution......
