Answer:

t=40.5

Step-by-step explanation:

T likely stands for time. but I suspect you haven't given us the full question because the piece you gave us doesn't determine what T stands for. either way, t is your variable. could be substituted for x or any other variable.

t2=81

isolate t

/2

t= 81/2

t= 40.5

inn [45]

The slope of the green line if the lines are perpendicular is -1/4

<h3>Perpendicular lines</h3>

For two lines two be perpendicular, the product of their slope must be -1. Let the slope of the red and green line be m1 and m2.

Given the following

Slope of red line = 4

According the definition

4m2 = -1

m2 = -1/4

Hence the slope of the green line if the lines are perpendicular is -1/4
