Answer:
total distance travel by them to cross river is 17.3 m
Step-by-step explanation:
Assume A be the initial position of both person and B as apposite point to A
u component of velocity along SOUTH DIRECTION is 4 cos30 = 0.4330 m/s
v component of velocity along SOUTH DIRECTION is 4 cos90 = 0 m/s
total speed will be = 0.4330 + 0 = 0.4330 m/s
time taken
time taken 
component of u in downstream direction = 4 cos120 = -0.25 m/s
component of v in downstream direction = 4 cos 0 = 0.5 m/s
total component in downstream will be -0.25 + 0.5 = 0.25
total distance travel by them to cross river is 
downstream.
Answer:
c. The score on the achievement test of both groups.
Step-by-step explanation:
A school psychologist recruits 600 second-grade students and randomly divides them into two groups.
Group 1 is taught by means of the new method, while Group 2 is taught via traditional methods.
We have to find the response variable. A response variable is the outcome variable or dependent variable in the experiment.
Here this is - The scores on the achievement tests of both group 1 and group 2.

Answer:
3x³ + 12x² - 7x - 28
Step-by-step explanation:
(f • g)(x) = f(x) × g(x)
= (x + 4)(3x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis
= 3x³ - 7x + 12x² - 28
= 3x³ + 12x² - 7x - 28
