Answer:
30.667, in 1 hour = 40 miles
Step-by-step explanation:
Set up a proportion so 1.5 miles / 2.25 minutes.
So 1.5/2.25 = x/46
solve for x 1.5(46)/2.25 = x so x = 30.667
In one hour is 60 minutes so 1.5(60)/2.25 = x
Answer:
The required position of the particle at time t is: 
Step-by-step explanation:
Consider the provided matrix.



The general solution of the equation 

Substitute the respective values we get:


Substitute initial condition 

Reduce matrix to reduced row echelon form.

Therefore, 
Thus, the general solution of the equation 


The required position of the particle at time t is: 
Answer:
8/3
Step-by-step explanation:
x equals 8/3
7x_2_4x_6=0
3x=8 ÷3 in both sides
Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables
