Answer:

4) CD =DC = 1  is true .

Step-by-step explanation:

Given  : If C and D are matrices and C is the inverse of D.

To find  :  which of the following is true.

Solution : We have given that  C and D are matrices and C is the inverse of D.

By the inverse matrix rule  : A^{}A^{-1}  = [tex]A^{-1} A^{}= 1[/tex].

Where A^{-1} is inverse of A matrix .

Then CD =DC = 1

Therefore, 4) CD =DC = 1  is true .

HELPPP!!! WILL MARK BRAINLIEST!!!
LenKa [72]

Answer:

Horizontal Asymptote:    y=2

Vertical Asymptote: x=3

Step-by-step explanation:

One way: Look at graph

Look at for a horizontal or vertical line that both lines don't touch.

Second Way:

When you look for vertical asymptotes, you set the denominator equal to zero and solve.

For example, the second question has a denominator of x-3.

x-3=0

x=3 (This is the vertical asymptote)

When you look for horizontal asymptote, you do long division.

For example, the first question f(x)=\frac{2x}{x-3}

The answer will be 2. 2 is the quotient. You only want quotient not remainder.

y=2.

The measure of an angle is 4y. Find the measure of its complement.
Serjik [45]
Complementary angles are angles whose measure add up to 90°.

So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.

Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.

Angles who has a sum of 180° are called supplementary angles.

What is the area of this figure?<br> A 78 in^2<br> B 48 in^2<br> C 30 in^2<br> D 18 in^2
Anika [276]
Let's break it up into 2 figures, the rectangle on the right with dimensions 3 x 10, and the rectangle on the left with dimensions 8 x 6.
A = 3 x 10
A = 8 x 6

A = 30
A = 48

The sum of these two, 78, will represent the area of the total figure.
