The value of [tex]\int\limits^{4}_{1} {x\cdot h''(x)} \, dx[/tex] is 8.5. The choice that represent the best approximation is A.

This integral can be approximated by the following Riemann sum:

[tex]A = \Sigma\limits_{i=0}^{2} \left\{(x_{i+1}-x_{i})\cdot x_{i}\cdot h''(x_{i})+\frac{1}{2}\cdot (x_{i+1}-x_{i})\cdot [x_{i+1}\cdot h''(x_{i+1})-x_{i}\cdot h''(x_{i})] \right\}[/tex]

[tex]A = \frac{1}{2} \cdot \Sigma\limits_{i=0}^{2} \left\{(x_{i+1}-x_{i})\cdot [x_{i+1}\cdot h''(x_{i+1})+x_{i}\cdot h''(x_{i})] \right\}[/tex]

Then, the approximate value of the integral is:

[tex]A = \frac{1}{2}\cdot \{(2-1)\cdot [(2)\cdot 2+(1)\cdot (-5)]+(3-2)\cdot [(3)\cdot 1+(2)\cdot 2]+(4-1)\cdot [(4)\cdot 2+(3)\cdot 1]\}[/tex]

[tex]A = 8.5[/tex]

The value of [tex]\int\limits^{4}_{1} {x\cdot h''(x)} \, dx[/tex] is 8.5. The choice that represent the best approximation is A. [tex]\blacksquare[/tex]

Selected values of the twice-differentiable function and its first and second derivatives are:

[tex]h(1) = 3[/tex], [tex]h(2) = 6[/tex], [tex]h(3) = 2[/tex], [tex]h(4) = 10[/tex]

The area of the rectangle is the product of its dimensions.

The width of the rectangle is [tex]5(19x^2 + 6x - 18)[/tex]

The area of the rectangle is given as:

[tex]Area = 5x^3(19x^2 + 6x - 18)[/tex]

The length of the rectangle is given as:

[tex]Length =x^3[/tex]

So, we have:

[tex]Area = Length * Width[/tex]

Substitute known values

[tex]5x^3(19x^2 + 6x - 18)= x^3* Width[/tex]

Divide through by x^3

[tex]5(19x^2 + 6x - 18)= Width[/tex]

Rewrite the equation as:

[tex]Width = 5(19x^2 + 6x - 18)[/tex]

Hence, the expression that represents the width of the rectangle is [tex]5(19x^2 + 6x - 18)[/tex]

Answer:

y = -8

Step-by-step explanation:

This problem is solved using substitution. So you need to start by substituting in the -9 for the 'x' in the main equation. This will give you something that looks like this:

[tex]7(-9)-10y=17[/tex]

Now just solve!

[tex]7(-9)-10y=17\\\\-63-10y=17\\\\-10y=80\\\\y=-8[/tex]

Hope this helps :)

Answer: y = -8

Step-by-step explanation:

Let

{1/(x+2y)} = u -----Eqn(1)

{1/(x-2y)} = v ------Eqn(2)

So, given equation can be rewritten as

⇛6u + 5v = -3 ---Eqn(3)

⇛3u + 7v = -6 -----Eqn(4)

On multiply equation (4) by 2, we get

⇛6u + 14v = -12 -----Eqn(5)

On subtracting equation (3) from equation (5), we get

⇛9v = -9

⇛v = -9/9

⇛v = -1 ----Eqn(6)

Put value of v in equation (3), we get

6u + 5v = -3

⇛6u + 5 * (-1) = -3

⇛6u -5 = -3

⇛6u = -3 + 5

⇛6u = 2

⇛u = 2/6

⇛u = (2÷2)/(6÷2)

⇛u = 1/3 -----Eqn(7)

Now, substituting value of u and v in equation (1) and equation (2), we get

{1/(x+2y)} = 1/3 and {1/(x-2y)} = -1

⇛x + 2y = 3 -----Eqn(8)

⇛x - 2y = -1 -------Eqn(9)

Now, add equation (8) and equation (9) , we get

⇛2x = 2

⇛x = 2/2

On substituting x = 1 in equation (8), we get

x + 2y = 3

⇛ 1 + 2y = 3

⇛2y = 3 - 1

⇛2y = 2

⇛y = 2/2

Therefore, x = 1 and y = 1

Answer: Hence the value of x and y is 1 and 1.

Answer:

D

Step-by-step explanation:

The range is the values of y covered by the graph

The graph on the left shows y going to - ∞

The graph has its maximum value at 4 ( turning point )

The range is therefore

- ∞ < y ≤ 4

Answer:

you solve these by plugging the numbers into pythagorean theorem which is

a^2 + b^2 = c^2 (a squared plus b squared equal c squared)

C is the hypotenuse which is the longest side across from the right angel (assuming all these problems are for right triangles)

so 17 would be 9.5^2 + 3.8^2 = c^2

So 90.25 + 14.44 = c^2

104.69=c^2

Then to solve for c take the square root of each side and get

10.23=c

To do the other ones where a or b doesn’t have a value, it’s almost the same but you just have to plug in the variables in different places and solve it

Answer:

5 hours and 15 minutes

Step-by-step explanation:

From 11:55 A.M. to 12:00 P.M. is 5 minutes.

From 12:00 P.M. to 12:10 P.M. is 10 minutes.

From 12:10 P.M. to 5:10 P.M. is 5 hours.

If you add all of that up to get the time that has elapsed, you will get 5 hours and 15 minutes.

Step-by-step explanation:

the sum of all the angles is 180° as it is a straight line.

so,

n + 6 + 90 + 2n + 3 = 180

3n + 99 = 180

3n = 180 - 99 = 81

n = 81/3 = 27

n = 27°

therefore, value of n is 27°.

Step-by-step explanation:

eqn of circle= (x-a)^2 + (y-b)^2 = r^2

where (a,b) is centre of circle.

(x+5)^2 = (x - (-5) )^2

Answer:

(6.25, 0.5 )

Step-by-step explanation:

2x - y = 12 → (1)

2x + y = 13 → (2)

Add the 2 equations term by term to eliminate y

4x + 0 = 25

4x = 25 ( divide both sides by 4 )

x = 6.25

substitute x = 6.25 into either of the 2 equations and solve for y

substituting into (2)

2(6.25) + y = 13

12.5 + y = 13 ( subtract 12.5 from both sides )

y = 0.5

solution is (6.25, 0.5 )
