Answers

Answer: $(x^2+3x+26)/(4x+8)$

Step-by-step explanation:

Since, according to the question the given expression,

$(x+8)/(x+2) + (x-3)/(4)$

= $(4(x+8)+(x-3)(x+2))/(4(x+2))$

= $(4x+32+(x-3)(x+2))/(4x+8)$ (By solving the parenthesis )

= $(4x+32+x(x+2)-3(x+2))/(4x+8)$ ( by distributive property)

= $(4x+32+x^2+2x-3x-6)/(4x+8)$ ( again on applying distributive property)

= $(3x+26+x^2)/(4x+8)$ ( by operating like terms)

= $(x^2+3x+26)/(4x+8)$

$(x + 8)/(x + 2) + (x - 3)/(4) = (4(x + 8))/(4(x + 2)) + ((x + 2)(x - 3))/(4(x + 2)) = (4(x) + 4(8))/(4(x + 2)) + (x(x - 3) + 2(x - 3))/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x(x) - x(3) + 2(x) - 2(3))/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x^(2) - 3x + 2x - 6)/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x^(2) - x - 6)/(4(x + 2)) = ((4x + 32) + (x^(2) - x - 6)/(4(x + 2)) = (x^(2) + (4x - x) + (32 - 6))/(4(x + 2)) = (x^(2) + 3x + 26)/(4(x + 2))$

Answers

Answer:

24π/5, 63/4, 15.758, 956√e

Note: The correct question is found in the attachment below

Step-by-step explanation:

Dividing to get values up to three decimal places

π = 3.142; e = 2.718

24π/5 = 24/5 × 3.142 = 4.8 * 3.142 = 15.0816

63/4 = 15.750

15.750 = 15.750

956 × √e

√e lies between 1.6 and 1.65 because 1.6 × 1.6 = 2.56

1.65 × 1.65 = 2.7225

Using 1.65

956 × 1.65 = 1577.4

Therefore, the correct ordering is 24π/5, 63/4, 15.758, 956√e

Identify the vertex of the quadratic function in standard form y=2x^2 -16x+31

Answers

Answer:

(4,1)

Step-by-step explanation:

The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).

To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.

To find the y-coordinate, input the x=4 and solve for y.

$y=2(4)^2-16(4)+31\ny=2(16)-64+31\ny=32-64+31\ny=1$

The vertex is (4,1).
