The altitude A in feet of a plane t minutes after takeoff is approximated by the function a=7000 In(0.2t)+2000. Solve for the t in terms of A. What is a situation in which it would be easier to use your new equation rather than the orginal

And for this case we can use the last equation when we want the altitude and we want to know how many minutes the plane was at air after the takeoff

Step-by-step explanation:

For this case we have the following function given :

Where:

A = feet of a plane and t = minutes after takeoff

And we are interested to solve t in terms of A

We can begin subtracting 2000 in both sides of the equation and we got:

Now we can divide both sides by 7000 and we got:

Now we can apply exponential in both sides of the equation and we got:

And now we can divide both sides by 0.2 and we got:

And for this case we can use the last equation when we want the altitude and we want to know how many minutes the plane was at air after the takeoff

mental cunning

explanation:

he is often referred to as a man of twists and turns

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
