Answer:

$3^{12}$

Step-by-step explanation:

$($ $3^{5}$ $)^{2}$

You multiply the exponents to get:

$3^{10}$

Then you divide it by $3^{-2}$

When dividing exponents, you subtract.

10 - - 2 = 12 so the exponent is 12.

That leaves us with:

$3^{12}$

Use the graph to determine the vertex point of the quadratic function. Is the vertex a

Feliz [49]

Answer:

B) Vertex (1,2), maximum

Step-by-step explanation:

First, determine if the graph has a maximum or a minimum value. Since the graph opens downwards, it has a <u>maximum</u> value.

The maximum is the point that has the greatest y value. We can see that the greatest y value is at $y=2$ . Going down two units from that spot, we can see that the x value is at $x=1$ . We can plug those into the vertex form, $(x,y)$ . By plugging in we get the point $(1,2)$ .

Matrix question help needed

kramer

The required matrix is:

$\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]$

Step-by-step explanation:

We need to apply elementary row operation -2R₂+3R₁ tothe matrix:

$A=\left[\begin{array}{ccc}-3&5&2\\8&-1&3\\\end{array}\right]$

Multiplying Row 2 with -2 and Row1 with 3 and adding,

-9 15 6

-16 2 -6

----------

-25 17 0

After applying this operation, Row 1 will be changed while Row 2 will remain same because we get -2R₂+3R₁ -> R₁

The required matrix is:

$\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]$

Try the first four cards in order from left to right. It starts with the expression, plugs in 6 for t, does 6 * 3 first because of PEMDAS, and then does 27 - 18, which is 9.

I need help finding a solution to this equation: 5 (n-1/10)=1/2

Readme [11.4K]

Answer:

n = 1/5

Step-by-step explanation:

Let's solve your equation step-by-step.

5(n− 1 /10 )= 1/ 2

Step 1: Simplify both sides of the equation.

5(n− 1 /10 )= 1 /2

(5)(n)+(5)( −1 /10 )= 1/2

(Distribute)

5n + −1 /2 = 1 /2

Step 2: Add 1/2 to both sides.

5n + −1 /2 + 1 /2 = 1 /2 + 1 /2

5n=1

Step 3: Divide both sides by 5.

5n /5 = 1 /5

n= 1 /5
