A boat is traveling east across a river that is 112 meters wide at 8 meters per second. If the river has a northward current of a 5 meters per second, what is the resultant speed of the motorboat rounded to the nearest tenth?
A)8.6 m/s
B)3.0 m/s
C)13.0 m/s
D)9.4m/s

D) 9.4 m/s

Step-by-step explanation:

The boat has an eastward speed of 8 m/s and a northward speed of 5 m/s.  The resultant speed can be found with Pythagorean theorem:

v² = (8 m/s)² + (5 m/s)²

v = 9.4 m/s

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
