Answer:
Step-by-step explanation:
There are two other important distances on a circle, the radius (r) and the diameter (d). The radius, the diameter, and the circumference are the three defining aspects of every circle. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points. The diameter will always pass through the center of the circle. The radius is half of this distance. You can also think of the radius as the distance between the center of the circle and its edge.
This diagram shows the circumference, diameter, center, and radius on a circle.

(I did the quiz and got it right :))
We have been given two matrices a and b. A has 6 rows and 7 columns, while b has 7 rows and 8 columns.
Since we know that order matters in matrix multiplication. In order for matrix multiplication to be defined number of columns in the first matrix should be equal to the number of rows of in the second matrix.
We can see that number of columns in matrix a and number of rows in matrix b is 7.
Therefore, size of ab will be equal to number of rows of matrix a and number of columns of matrix b that is 6 by 8.
Now we will see whether ba is defined or not. We can see columns in matrix b are 8 and rows in matrix a are 6, which is not equal. So we can say that ba is not defined.
Therefore, size of ba is not defined (dne).
Answer:
a) y = 0.55x + 75
b) $108
Step-by-step explanation:
a) to find the equation represent the sequence use the y=mx+b formula
y = total price
m = cost per mile
x = miles driven
b = flat fee
Therefore y = 0.55x+75
b) To figure out the cost of driving 60 miles you use the equation y = 0.55x + 75
y = 0.55 X 60 + 75
= 108
Therefore the cost of renting the truck and driving 60 miles is $108
The y-intercept will be 1
