Answer:
Gas mileage is 17.29
Explanation:
Given data:
The total number of the model is 35
The total size of the engine is 5 ltr
The regression model is given as
From the information given in question we have
Regression equation is : model- mpg 
Therefore for engine capacity of 5 liters;
Gas mileage 
Gas mileage is 17.29
Setting up an integral of
rotation is used as a method of of calculating the volume of a 3D object formed
by a rotated area of a 2D space. Finding the volume is similar to finding the
area, but there is one additional component of rotating the area around a line
of symmetry.
<span>First the solid of revolution
should be defined. The general function
is y=f(x), on an interval [a,b].</span>
Then the curve is rotated
about a given axis to get the surface of the solid of revolution. That is the
integral of the function.
<span>It all depends of the
function f(x), which must be known in order to calculate the integral.</span>
Answer:
3km due West
Explanation:
Displacement is the distance traveled in a specific direction. From this definition, we can see that displacement is a vector quantity that has magnitude and direction.
So;
For the first day, the person walks 4km East:
4km
Start ----------------------------→ first day
7km
← ------------------------------------------------------ Second day
The displacement of the boy = 7km - 4km = 3km due West
given that acceleration due to gravity is g = 10 m/s^2
speed of the rocket will reach to 0.9c
now by kinematics
Part b)
distance traveled by it in above time
so this is the distance covered by the object
Answer:
Please see the direction of force in the attachment
Explanation:
As the particle enters the capacitor, it experiences electric. In order to move in the same direction as the electron was moving before entering the capacitor, the force due to the electric field of capacitor must be balanced by the magnetic field.
The direction of particle is shown in the attachment.
As we know,
Force = q (v *B)
