Answer:

a. k = 6 b. $66

Step-by-step explanation:

$\frac{18}{3}$ = 6 k is 6

(I know where this question goes so I'll do the rest)

y = 6x

y = 6 · 11

y = 66

The dry cleaner would charge $66

Prove that if b is a square matrix then b+b^t is symmetric

WARRIOR [948]

A matrix $\mathbf X$ is symmetric if $\mathbf X=\mathbf X^\top$ . We have

$(\mathbf B+\mathbf B^\top)^\top=\mathbf B^\top+(\mathbf B^\top)^\top=\mathbf B^\top+\mathbf B=\mathbf B+\mathbf B^\top$

and so $\mathbf B+\mathbf B^\top$ is indeed symmetric.

Answer: a) Horizontal Compression, Left 1, Up 2

Step-by-step explanation:

$\sqrt{3x+3}+2\implies \sqrt{3(x+1)}+2\\\\\bullet \text{The 3 represents a horizontal compression by a factor of }\dfrac{1}{3}\\\\\bullet \text{The 1 under the square root represents a shift to the LEFT 1 unit}\\\\\bullet \text{The 2 outside of the square root represents a shift UP 2 unit}$

Using prime factorization what is the GCF 3y 2 squared, 24y 3 cubed

WINSTONCH [101]

Answer:

$3y^2$

Step-by-step explanation:

Given:

To find the GCF of $3y^2\ and\ 24y^3$ using prime factorization.

Writing each in prime factors:

3 = 1 $\times$ 3

24 = 1 $\times$ 2 $\times$ 2 $\times$ 2 $\times$ 3

Now, GCF of 3 and 24 is 3

$y^2=1\times y\times y$

$y^3=1\times y\times y\times y$

GCF of $y^2$ and $y^3$ is $y\times y=y^2$ .

Therefore, the overall GCF of the two terms is $3y^2$
