Step-by-step explanation:
The displacement of a particle d (in km) as a function of time t (in hours) is given by :

Displacement at t = 4 hours,

Velocity of particle is given by :

Velocity at t = 4 hours,

Acceleration of the particle is given by :

At t = 4 hours,

Therefore, the displacement, velocity and acceleration at t = 4 hours is 205 km, 136 km/h and 58 km/h² respectively.
Answer:
X:1 2 3 4 5 Y:7 11 15 19 23.
Step-by-step explanation:
We just need to put in the values of x into the equation: y = 4x + 3.
<u>x = 1: </u>
y = 4(1) + 3
= 4 + 3
y = 7
<u>x = 2: </u>
y = 4(2) + 3
= 8 + 3
y = 11
<u>x = 3:</u>
y = 4(3) + 3
= 12 + 3
y = 15
<u>x = 4:</u>
y = 4(4) + 3
= 16 + 3
y = 19
<u>x = 5:</u>
y = 4(5) + 3
= 20 + 3
y = 23
Answer:
x ≤ 1
Step-by-step explanation:
8 + 4x
12
4x
12 - 8
4x ≥ 4
Dividing both sides by 4 gives;
x ≤ 1
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
In this case we have the following equation of the line:

Where:

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have an equation of the form:

Substitute the given point
to find "b":

Finally, the equation of the requested line is:

Answer:

Answer:
B is greater than A
Step-by-step explanation:
B is greater than A coz A has the smallest population. The population was due 2012 and B=2.5million and A=1.8million that means B is greater than A
