Answer: 5376
Step-by-step explanation: if a chessboard have 64 squares that means 84 squares used at the tournament will have 5376 squares all together by multiplying 64 × 84.
C is the least that is beause it is .015 which is smaller than 0.15
Answer:
where denotes speed of the car
Step-by-step explanation:
Given: The speed limit on a city street is 35 kilometers per hour.
To write and graph: an inequality to describe a car’s possible speed.
Solution:
Let the speed of a car be kilometers per hour.
As the speed limit on a city street is 35 kilometers per hour,
First draw the graph of (see figure a.)
Plot the points
Take a point on the left side of line x = 35 say and put it in
which is true.
So, shade the graph on the left side of line x = 35
See the graph b.
the pink part represents the inequality
Answer:
It is proved that is a solution of Ax=b.
Step-by-step explanation:
As given let w and p be a solution of Ax=b. Then,
and
Defining,
To show is a solution of Ax=b, we have to show . Then,
(By putting value of )
(By distributive law)
(Since w and p are solution of Ax=b)
Hence become a solution of the homogenous system Ax=b.
Since w and p are solution of Ax=b, and any linear combination of the solutions again a solution of Ax=b, this shows that every solution of Ax=b is of the form where is a solution of Ax=0.
