PLS HELP OM, ITS DUE TONIGHT AND PLS EXPLAIN!!! IM STUCK ON THIS ONE QUESTION, AND I NEED TO SHOW WORK. I WILL MARK BRAINEST, PL 1. a popular sprinter of mass 60 kg, was running a 100 m race. her velocity was measured over a 10.0 s period. the results are recorded in table

1. velocity, v/ms-1 0.0 2.5 5.0 7.5 10.0 10.0 time, t's 0.0 2.0 4.0 6.0 8.0 10.0
a. use the results from table 1 to plot a graph of velocity versus time on a graph paper.

b. determine the slope of the graph over the first 6.0 s of the race.

c. what quantity does the slope of the graph represent?

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

answer: 819.89 miles across america

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
