That bracket symbol, with an r in it, means "the absolute value of r". 
So r's absolute value is -2 meaning r is two units from zero
r= 2

A bicycle racer sprints at the end of a race to clinch a victory. The racer has an initial velocity of 10.0 m/s and accelerates
Grace [21]

Answer:

20m/s

Step-by-step explanation:

This can be solved using the acceleration / velocity equations.

Specifically,

v² = u² + 2as

Where

v = final velocity = what we need to find

u = initial velocity = given as 10.0m/s

a = acceleration = given as 0.5m/s²

s = distance = 300m

Hence,

v² = 10² + (2)(0.5) (300)

    = 100 + 300

    =400

v = √400 = 20 m/s

_2. You have a part-time job 4 days per week, 5 hours per day. How many hours will you work in two weeks?
marta [7]

Answer:

C) 40

Step-by-step explanation:

For every one day your work is 5 hours.

1 day = 5 hours

Set up a proportion so it would be:

\frac{1 day}{5 hours} = \frac{4 days}{x hours}

4 days x 5 hours = 20 hours/week

So now you know you know you work 20 hours/week, then multiply by 2 since they're asking how many hours will you work in two weeks:

20 hours x 2 weeks = 40 hours in two weeks

A model for this data is N=1.45t +25.9 where t represents time in years, with t=10 corresponding to the year 2010. According to
Andrew [12]

Answer:

In year 2029

Step-by-step explanation:

N=1.45t+25.9

67.95=1.45t+25.9

67.95-25.9=1.45t

t=(67.95-25.9)/1.45

t=29

so if t=10 correspond to the year 2010, t=29 correspond to the year 2029
