Answer: A. \left[\begin{array}{ccc}29&13\\13&10\\\end{array}\right]

Step-by-step explanation:

The question is asking us to find the product of the matrices. The key difference is the second A has a little <em>T</em> in the exponent. This <em>T</em> means transpose. You multiply A by the transpose of A. To find the transpose, you turn the rows into columns.

A^T=\left[\begin{array}{ccc}5&3\\2&-1\\\end{array}\right]

Now that we have our transpose, we can multiply the matrices.

\left[\begin{array}{ccc}5&2\\3&-1\\\end{array}\right] \left[\begin{array}{ccc}5&3\\2&-1\\\end{array}\right] =\left[\begin{array}{ccc}5*5+2*2&5*3+2(-1)\\3*5+2(-1)&3*3+(-1)(-1)\\\end{array}\right] =\left[\begin{array}{ccc}29&13\\13&10\\\end{array}\right]

Pls help asap!! Hhuwdqnjwl

Answer:

14

Step-by-step explanation:

To get the answer, add the whole numbers together and then add the fractions together:

9 + 4 = 13

(You can even stop here because 14 is the closest to 13)

Now, add the fractions:

\frac{2}{3}+\frac{1}{5}

To add fractions you have to have a common denominator. To find the common denominator multiply 3 by 5, and 5 by 3. Like this:

(\frac{5}{5})\frac{2}{3}  + \frac{1}{5} (\frac{3}{3} )

Simplify:

\frac{10}{15} +\frac{3}{15}              Distribute everything from above

\frac{13}{15}                      Add

So, the whole fraction will look like this 13\frac{13}{15}. This is closest to 14.

Hope this helps!! Ask questions if you need!

6. what point does this line pass through, which is the basis of this equation?<br> y-3=3(x+1)
Vlada [557]

Answer:

Step-by-step explanation:

y - y1 = m(x - x1)

ur points are gonna be x1 and y1

y - 3 = 3(x + 1)

so ur y point is gonna be -3

but ur x point is gonna be -1.......because 3(x + 1) is the same as 3(x - (-1)

ur point is (-3,-1)
