The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

<h3>What is the matrix about?</h3>

Looking at the product of matrix, note that to multiply  the two matrix, the column of the first matrix needs to have the same or equal to the row of the 2nd matrix.

And in this case (propensity), it is not satisfied by the first  option because:

C =  3 x 1  and

O= 2 x 1  matrix

In this case CD is therefore undefined.

So we can say that The product that is  undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

Please Help!!!!!<br><br> Which method can you use to prove these triangles congruent?
Trava [24]

Answer: The HL Theorem.

Step-by-step explanation: We are given that the triangles have a congruent 90 degree angle and two congruent sides. This would indicate towards SAS but in this case, that doesn't work because the angle is not in between the two congruent sides. We know that the triangles are right, and that their hypotenuses are congruent and that one leg is congruent. Thus, the answer must be HL (hypotenuse & leg).

Phoenix [80]

Answer:

Each will pay $61.75.

Step-by-step explanation:

How many gallons were used?

Each 100 miles, 3 + 1/4 = 3 + 0.25 = 3.25 gallons are used. The trip has 1500 miles.

100 miles - 3.25 gallons

1500 miles - x gallons

100x = 1500*3.25

x = \frac{1500*3.25}{100}

x = 48.75

Cost

Each gallons costs $3.80.

48.75 gallons cost 48.75*3.80 = $185.25

Split among the three friends envenly, how much will each pay?

185.25/3 = 61.75

Each will pay $61.75.
