Step-by-step explanation:

The expression x^2 + 8x + 3 to complete the square is 16.

The value we need to add in the blank space in the expression x^2 + 8x + 3 to complete the square is 16.

Here's how we can get that value:

Step 1: Divide the coefficient of the x term by 2 and square the result. That is, (8/2)^2 = 16.

Step 2: Add the value obtained in Step 1 to the expression in the blank space. Thus, x^2 + 8x + 3 + 16 = x^2 + 8x + 19.

Now, we have the perfect square trinomial x^2 + 8x + 16, which is the square of (x + 4).

Therefore, we can write x^2 + 8x + 19 as (x + 4)^2 - 3.

Thus, the value we can add in the blank space in the expression x^2 + 8x + 3 to complete the square is 16.

Answer:

\((x,y) = ( 5 , - 7)\)

Step-by-step explanation:

we would like to solve the following system of linear equation by substitution:

\( \displaystyle \begin{cases} y = x - 12\\ 8x + 8y = - 16\end{cases}\)

notice that, we're already given the value of y therefore simply substitute it to the II equation

\(8x + 8(x - 12) = - 16\)

distribute:

\(8x + 8x - 96= - 16\)

simplify addition:

\(16 x- 96= - 16\)

isolate -96 to left hand side and change its sign:

\(16 x= - 16 + 96\)

simplify addition:

\(16 x= 80\)

divide both sides by 16 and that yields:

\( \boxed{x= 5}\)

now substitute the got value of x to the first equation:

\(y = 5- 12\)

simplify subtraction:

\(y = - 7\)

hence,

the solution is (x,y)=(5,-7)

Solve by substitution :

y = x - 12

8x + 8y = -16

y = x - 12 ------- eq(1)

8x + 8y = -16 ------- eq(2)

Finding x ⤵

Putting y = x - 12 in eq(2) we get

Finding y ⤵

Putting x = 5 in eq(1) we get

Hence, x is 5 and y is -7

Answer:

Lesser x = -14

Greater x = 0

Step-by-step explanation:

Given equation:

\(\sf (x+7)^2-49=0\)

Add 49 to both sides:

\(\implies \sf (x+7)^2-49+49=0+49\)

\(\implies \sf (x+7)^2=49\)

Square root both sides:

\(\implies \sf \sqrt{(x+7)^2}=\sqrt{49}\)

\(\implies \sf x+7=\pm7\)

Solve for x:

\(\implies \sf x+7=7 \implies x=0\)

\(\implies \sf x+7=-7 \implies x=-14\)

To find the equation of the sphere tangent to the plane 2x + 3y - 6z = 5 with center C(-2, 3, 7), we need to find the radius of the sphere. The equation of the sphere is (x + 2)^2 + (y - 3)^2 + (z - 7)^2 = 36.

The distance from the center of the sphere to the plane is equal to the radius. We can use the formula for the distance between a point (x, y, z) and a plane Ax + By + Cz + D = 0:

Distance = |Ax + By + Cz + D| / sqrt(A^2 + B^2 + C^2)

In this case, the plane equation is 2x + 3y - 6z - 5 = 0. Plugging in the coordinates of the center C(-2, 3, 7) into the formula, we have:

Distance = |2(-2) + 3(3) - 6(7) - 5| / sqrt(2^2 + 3^2 + (-6)^2)

= |-4 + 9 - 42 - 5| / sqrt(4 + 9 + 36)

= |-42| / sqrt(49)

= 42 / 7

= 6

So, the radius of the sphere is 6.

The equation of a sphere with center C(-2, 3, 7) and radius 6 is:

(x + 2)^2 + (y - 3)^2 + (z - 7)^2 = 6^2

Simplifying further, we have:

(x + 2)^2 + (y - 3)^2 + (z - 7)^2 = 36

Therefore, the equation of the sphere is (x + 2)^2 + (y - 3)^2 + (z - 7)^2 = 36.

A linear function is defined as an equation in which the highest exponent of the variable is always one.

The graph is given in the question, as shown

Let y be represents the amount of fuel on the plane, in gallons,

And x represents the function of the flight time, in hours.

As per the given graph, we take two points (0, 63,500) and (16, 0)

y - 63,500 = [(0-63,500)/(16-0)](x-0)

y - 63,500 = (63,500/16)x

y - 63,500 = 3968.75x

Answer:

Undifined

Step-by-step explanation:

The estimated value of the double integral using Riemann sum with partition P2 is 0.611.

To estimate the double integral of the function f(x,y) = 4xy over the region r = [0,1] x [0,1], we can use Riemann sums with different partitions of the region.

First, we can divide the region into 6 rectangular subregions of equal size, using the partition:

P1 = {[0,1/3] x [0,1/2], [0,1/3] x [1/2,1], [1/3,2/3] x [0,1/2], [1/3,2/3] x [1/2,1], [2/3,1] x [0,1/2], [2/3,1] x [1/2,1]}

The area of each subregion is (1/3) * (1/2) = 1/6, so the Riemann sum is:

R1 = (1/6) * [f(1/6,1/4) + f(1/6,3/4) + f(1/2,1/4) + f(1/2,3/4) + f(5/6,1/4) + f(5/6,3/4)]

Plugging in the function f(x,y) = 4xy and simplifying, we get:

R1 = (1/6) * [(1/6)*(1/4)4 + (1/6)(3/4)4 + (1/2)(1/4)8 + (1/2)(3/4)8 + (5/6)(1/4)4 + (5/6)(3/4)*4]

= 11/18

Therefore, the estimated value of the double integral using Riemann sum with partition P1 is approximately 0.611.

Alternatively, we can use another partition with 6 rectangular subregions, such as:

P2 = {[0,1/2] x [0,1/3], [1/2,1] x [0,1/3], [0,1/2] x [1/3,2/3], [1/2,1] x [1/3,2/3], [0,1/2] x [2/3,1], [1/2,1] x [2/3,1]}

The area of each subregion is again 1/6, so the Riemann sum is:

R2 = (1/6) * [f(1/4,1/6) + f(3/4,1/6) + f(1/4,1/2) + f(3/4,1/2) + f(1/4,5/6) + f(3/4,5/6)]

Plugging in the function f(x,y) = 4xy and simplifying, we get:

R2 = (1/6) * [(1/4)*(1/6)4 + (3/4)(1/6)4 + (1/4)(1/2)8 + (3/4)(1/2)8 + (1/4)(5/6)4 + (3/4)(5/6)*4]

= 11/18

Therefore, the estimated value of the double integral using Riemann sum with partition P2 is also approximately 0.611.

In both cases, the estimated value of the double integral is the same, which suggests that it is a reasonable estimate.

The solution for x is x ≤ -3/4.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

To solve for x in the inequalities:

5x - 4 ≥ 12 and 12x + 5 ≤ -4

We'll solve each inequality separately:

5x - 4 ≥ 12

Adding 4 to both sides, we get:

5x ≥ 16

x ≥ 16/5

So the first inequality is solved for x as x ≥ 16/5.

Now, 12x + 5 ≤ -4

Subtracting 5 from both sides, we get:

12x ≤ -9

x≤ -9/12

x≤ -3/4

The only values of x that satisfy both inequalities are those that are less than or equal to -3/4.

Therefore, the solution for x is x ≤ -3/4.

Unfortunately, I am unable to directly interpret or visualize figures or images. However, I can provide you with a general explanation. In a discretized reservoir using block-centered grids, the standard ordering refers to the arrangement of grid cells or blocks in a particular pattern.

This pattern is often used to establish the connectivity and adjacency relationships between the cells in the reservoir model. Typically, the standard ordering arranges the grid cells in a sequential manner, starting from the top-left corner and moving row by row. Each grid cell represents a discrete volume or unit in the reservoir. The non-zero elements, indicated by the "x" positions in the coefficient matrix, would correspond to the active or connected cells within the reservoir model. These active cells are the ones that contribute to fluid flow and other reservoir properties. To visualize the discretized reservoir using the standard ordering, you would need to refer to the coefficient matrix and determine the dimensions of the reservoir model, such as the number of rows and columns. Then, starting from the top-left corner, you can represent each active cell or block using a graphical representation, such as a square or rectangle, in a sequential manner based on the standard ordering. This way, you can construct a visual representation of the discretized reservoir model.
