Answer:

He needs 8.75 ft² polka dot paper to cover the board.

Step-by-step explanation:

How much polka dot paper she need to cover the board is the area of the board . The is a rectangle with length 3.5 ft long and width of 2.5 ft wide .

The area of the board(rectangle) = length × width

Area = LW

where

L= 3.5 ft

W = 2.5 ft

Area = 3.5 × 2.5

Area = 8.75 ft²

He needs 8.75 ft² polka dot paper to cover the board.

Given that P(x)=2x²+5x-5

IRISSAK [1]

Answer:

$(i) P(\frac{1}{2}) = 2*(\frac{1}{2})^2 + 5*\frac{1}{2} -5$

$=\frac{1}{2} +\frac{5}{2} -5\\\\=3-5 = -2$

$(ii) P(3) - Q(2) = 2(3^2)+5(3)-5 -[4(2^2) +3(2) +2]$

$= 18 + 15 -5 -16-6-2= 28-24 =4$

$(iii) P(x)\cdot Q(x) = (2x^2+5x-5)(4x^2-3x+2)$

$=2x^2(4x^-3x+2) +5x(4x^2-3x+2)-5(4x^2-3x+2)\\\\=8x^4 -14x^3 -11x^2 -10x-20x^2+15x-10\\\\=8x^4 - 14x^3 -31x^2 +5 -10$

$(iv) P(x) + Q(x) = 2x^2 +5x -5 + 4x^2 -3x +2$

$= 6x^2 +2x -3$

Which of the following rational functions is graphed below?

yawa3891 [41]

Answer:

The answer is option A.

Step-by-step explanation:

In order to find the equation of the function, when the graph is already known to us in the question, we can use the various coordinates points through which the curve is passing from. The various Asymptotes of the graph can be used to find the expression in the denominator of the function.

So here the graph is of the form:

$y=1/((x-a)(x-b))$

Now when the value of x=-6 and x=6, we have the vertical asymptote, so at x=-6 and x=6 is where the vertical asymptotes lies.

Thus, we have a=6, b=-6.

And hence, the function whose graph is given will be

$y=\frac{1}{\left(x-6\right)\left(x+6\right)}$

which is given by option A.
