Afootball team has 4 chances with the ball to gain 10 yards and keep going to try and make a touchdown a team gained 7 yards, lost 2, gained 4, and lost 1 how many total yards did the team move (forwards or backwards)?

They moved 8 yards forwards.

Step-by-step explanation:

They gained 7, lost 2, gained 4, and then lost 1.

7-2= 5+4= 9-1= 8. That's the total amount of yards they moved and the number is positive and not negative so they moves forwards 8 yards.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
