Answer:

Remainder is 1.

Step-by-step explanation:

Given is an algebraic quadratic function in x as

x^2+3x-9

and we have to divide by x-2.

We find that leading terms are x square and x so quotient I term is x.

x-2) x^2+3x-9(x+5\\       x^2-2x\\       -----------\\              5x-9\\               5x-10\\      ----------------\\                    +1\\       -----------------

Hence quotient is x+5 and remainder is 1

remainder = 1

(x² + 3x - 9 )÷ (x - 2 ) =  x + 5 + \frac{1}{x-2}

Answer:

<h2>AB=8.4 inches</h2><h2>AC=13.05 inches</h2>

Solution,

\frac{ab}{bc}   = tan \: 40 \\ ab = bc \times tan \: 40 \\ ab = 10 \times 0.84 \\ ab = 8.4 \: inches \:

\frac{bc}{ac}  = cos \: 40 \\  \frac{bc}{cos \: 40}   = ac \\ ac =  \frac{10}{cos \: 40}  \\ ac = 13.05 \: inches

Hope this helps...

Good luck on your assignment..

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Answer:

Graph A → y=√x.

Graph B → y=(√x) - 1.

Graph C → y=√(x-1).

Graph D → y= -√x.

Graph E → y= -√(x-1)

Step-by-step explanation:

The graph 'A' intercepts the y-axis at (0, 0). Therefore it belongs to the function y=√x.

The graph 'D' is exactly the same graph 'A' but reflected across the x-axis. Therefore, it belongs to the function y=-√x.

The function 'C' is exactly the same function y=√x but translated one unit to the right, therefore, the solution function is y=√(x-1)

The graph 'E' is exactly the same graph 'C' but reflected across the x-axis, therefore the function is: y= -√(x-1)

In the options you have two times the function y=√x. I assume that's a mistake. The graph 'B' corresponds to y = (√x) - 1
