Find the product. (-5a2)3 · a5

lesya692 [45]

Answer:

$-125a^{11}$

Step-by-step explanation:

The expression that we have in this problem is

$(-5a^2)^3\cdot a^5$

First of all, we proceed by evaluating the power of the term in the brackets. We apply the rule:

$(a^m)^n=a^{m\cdot n}$

$(a^2)^3=a^6$

Moreover, we have

$(-5)^3=-125$

Therefore,

$(-5a^2)^3=-125 a^6$

So now the expression is

$-125a^6 \cdot a^5$

Now we apply the following rule:

$a^m \cdot a^n = a^{m+n}$

So we have

$a^6\cdot a^5 = a^{6+5}=a^{11}$

Therefore, our expression becomes:

$-125a^6\cdot a^5=-125a^{11}$

What is the solution to the system of linear equations represented by the matrix below?

olga_2 [115]

$\begin{bmatrix}2&4\\1&2\end{bmatrix}\begin{bmatrix}x\\y\end{bmatrix}=\begin{bmatrix}6\\3\end{bmatrix}$

Notice that the second row is half the first, so the rows are dependent. This means there are infinitely many solutions to the system.

Isaiah and Wanda both went bowling last weekend, but not together. Isaiah went during open bowling time, paying $16 for shoe ren

DIA [1.3K]

Answer:

1 hour

Step-by-step explanation:

Let the number of hours bowled by Isaiah and Wanda be X

Isaiah spent 16 dollars on shoe rental and 2X on bowling

Wanda spent 13 dollars on shoe rental and 5X on bowling

Since they spent the same amount, set up an equation

16+2X=13+5X

subtract 2X on either side, then subtract 13 from either side we get

3X=3

divide both sides by 3

X=1
