Answer:
Explanation:
Given that:
A cyclist rides 4.0 km due west, then 12.0 km 33° west of north. From this point she rides 9.0 km due east.
Let:
Assuming that:
east is the + x axis and has a unit vector of
north is the +y axis and has a unit vector of
west is the - x axis and has a unit vector of
south is the - y axis and has a unit vector of -
The displacement in a given direction of x can be expressed by the formula:
The displacement in a given direction of y can be expressed by the formula:
The final displacement can be expressed by the relation;
It has a flexible vertibrae which allows it to move faster and fit into places . Plus it also allows it to get its prey easier
Answer:
The correct answer is B.
Explanation:
Step 1:
The available regression equation is: Predict height= 0.29 + 0.48 (age).
Here, the predict height is dependent variable and the age is in-dependent variable.
Intercept = 0.29
Slope = 0.48
The given regression equation indicates the y on x model and the intercept coefficients of the regression equation is 0.29 and the slope is 0.48.
Step 2:
The height increases, an average, by 0.48 m per year.
Because co-efficient of slope variable indicate the positive sign and we increase 1 year in age then automatically height increased is 0.48 m.

The height increases, on average, by 0.48 meter each year.</h3>
Answer:
the pressure will decrease by 1/2
Explanation:
PV=nRT
P=(nRT)/(V)
nRT are all constant so they will equal 1
V is 2
P=1/2
Answer:
Resistance
Explanation:
Resistance "resists" the flow of electricity and makes it more difficult to travel. The higher the resistance the less current there is in a circuit. Example being, open circuit (infinity ohms) means there is no current flowing with ohms law.
