Answer:

LM = 12.1

Step-by-step explanation:

Trapezoid

The midsegment (also known as the median or midline) of a trapezoid is the segment that joins the midpoints of the legs.

The midline is parallel to the bases a and b and its length m is equal to the average of the lengths of the bases of the trapezoid:

\(\displaystyle m = \frac{a + b}{2}\)

Since JP and PM are congruent and KQ and QL are congruent, PQ is the midline of the trapezoid JKLM.

We are given the midline m=11.4 and one of the bases a=10.7. We can find the other base by solving for b:

b = 2m - a

b = 2*11.4 - 10.7

b = 12.1

LM = 12.1

The optimal solution for the given linear programming problem is z = 2, x₁ = 0, x₂ = 2, x₃ = 0, x₄ = 6, x₅ = 2, x₆ = 0 and x₇ = 0.

To solve the given linear programming problem using the simplex method, we need to convert it into standard form. The standard form of a linear programming problem involves introducing slack, surplus, and artificial variables as necessary.

The original problem is:

Minimize z = x₁ + 2x₂ + 3x₃ - x₄

Subject to:

2x₁ - x₂ + x₃ - 2x₄ ≤ 6

-x₁ + 2x₂ + x₃ + x₄ ≤ 8

2x₁ + x₂ + x₃ + x₄ ≥ 2

0 ≤ x₁ ≤ 3

1 ≤ x₂ ≤ 4

0 ≤ x₃ ≤ 2

2 ≤ x₄ ≤ 5

To convert the problem into standard form, we introduce slack variables and convert inequalities to equations:

Minimize z = x₁ + 2x₂ + 3x₃ - x₄

Subject to:

2x₁ - x₂ + x₃ - 2x₄ + x₅ = 6

-x₁ + 2x₂ + x₃ + x₄ + x₆ = 8

2x₁ + x₂ + x₃ + x₄ - x₇ = 2

x₁, x₂, x₃, x₄, x₅, x₆, x₇ ≥ 0

0 ≤ x₁ ≤ 3

1 ≤ x₂ ≤ 4

0 ≤ x₃ ≤ 2

2 ≤ x₄ ≤ 5

Now we can set up the initial simplex tableau:

   BV   x₁   x₂   x₃   x₄   x₅   x₆   x₇   RHS

----------------------------------------------

  x₅    2   -1    1   -2    1    0    0    6

  x₆   -1    2    1    1    0    1    0    8

  x₇    2    1    1    1    0    0   -1    2

Next, we perform iterations of the simplex method until we reach the optimal solution. The iteration process involves finding the entering variable, the leaving variable, and updating the tableau.

Iteration 1:

Entering variable: x₂ (the most negative coefficient in the objective row)

Leaving variable: x₆ (minimum ratio test)

Pivot on row 2, column 3:

   BV   x₁   x₂   x₃   x₄   x₅   x₆   x₇   RHS

----------------------------------------------

  x₅    2    0    1   -2   -1    1    0    2

  x₂   -0.5   1    0    0    0.5 -0.5  0    2

  x₇    1    0    0    1   -1    1    -1   6

Iteration 2:

Entering variable: x₃ (the most negative coefficient in the objective row)

Leaving variable: x₇ (minimum ratio test)

Pivot on row 3, column 4:

   BV   x₁   x₂   x₃   x₄   x₅   x₆   x₇   RHS

----------------------------------------------

  x₅    2    0    1   -2   -1    1    0    2

  x₂   -0.5   1    0    0    0.5 -0.5  0    2

  x₄    1    0    0    1   -1    1    -1   6

The tableau is now in its final form, and we have reached the optimal solution:

z = 2

x₁ = 0

x₂ = 2

x₃ = 0

x₄ = 6

x₅ = 2

x₆ = 0

x₇ = 0

Therefore, the optimal solution for the given linear programming problem is:

z = 2

x₁ = 0

x₂ = 2

x₃ = 0

x₄ = 6

x₅ = 2

x₆ = 0

x₇ = 0

Answer:

Step-by-step explanation:

brainliest when possible.

the position function is: r(t) = (3/2t^2 - 5, 4e^(-t) -  3t - 2, t^4 - 3t - 3) if acceleration  a=(3,-4e^-t,12t^2) ,velocity  v(0)=(0,1, -3) and position is r(O)=(-5,2, -3).

The acceleration of an object is given by a = \((3, -4e^(-t), 12t^2)\).The initial velocity of the object is v(0) = (0, 1, -3) and the initial position of the object is r(0) = (-5, 2, -3).We are required to determine the velocity and position functions of the object.

To determine the velocity function v(t), we need to integrate the acceleration function `a` with respect to time t.

v(t) = ∫a(t) dt v(t)

= (∫3 dt, ∫-4e^(-t) dt, ∫12t^2 dt)

v(t) = (3t + C1, 4e^(-t) + C2, 4t^3 + C3) where C1, C2, and C3 are constants of integration.

Since the initial velocity of the object is v(0) = (0, 1, -3), we can determine the constants C1 and C2.v(0) = (3(0) + C1, 4e^(0) + C2, 4(0)^3 + C3) (0, 1, -3)

= (C1, 4 + C2, C3)(C1, C2, C3)

= (0, -3, -3)

Therefore, the velocity function is:v(t) = (3t, -4e^(-t) - 3, 4t^3 - 3)

To determine the position function r(t), we need to integrate the velocity function v with respect to time t.r(t) = ∫v(t) dt r(t) = (∫3t dt, ∫(-4e^(-t) - 3) dt, ∫(4t^3 - 3) dt)

r(t) = (3/2t^2 + C4, 4e^(-t) - 3t + C5, t^4 - 3t + C6)`where C4, C5, and C6 are constants of integration .Since the initial position of the object is r(0) = (-5, 2, -3)`, we can determine the constants C4, C5, and C6.r(0) = (3/2(0)^2 + C4, 4e^(-0) - 3(0) + C5, (0)^4 - 3(0) + C6) (-5, 2, -3)

= (C4, 4 + C5, C6)(C4, C5, C6)

= (-5, -2, -3)

The area of the circular shaded area is of 116.113 cm².

The area of a circle of radius r is given by pi multiplied by the radius squared, as follows:

A = πr²

For this problem, the shaded area is the area of the larger circle subtracted by the area of the smaller circle. We have that:

Hence the area of the larger circle is given by:

Al = π(6.5)² = 132.732 cm².

The area of the smaller circle is given by:

As = π(2.3)² = 16.619 cm².

Hence the shaded area is given by:

A = Al - As = 132.732 - 16.619 = 116.113.

The shaded area is of 116.113 cm².

The equivalent expression for 1.5 cubed over 1.3 raised to the fourth power all raised to the power of negative six is 1.5 to the eighteenth power over 1.3 to the twenty-fourth power.

Here are the steps to simplify the expression:

Apply the negative power rule: (1.5 cubed over 1.3 raised to the fourth power) raised to the power of negative six is equal to (1.3 raised to the fourth power over 1.5 cubed) raised to the power of six.

Apply the power of a quotient rule: (1.3 raised to the fourth power over 1.5 cubed) raised to the power of six is equal to (1.3 raised to the fourth power)⁶ / (1.5 cubed)⁶.

Apply the power of a power rule: (1.3 raised to the fourth power)⁶ is equal to 1.3(⁴*⁶) = 1.3²⁴.

Apply the power of a power rule: (1.5 cubed)⁶ is equal to 1.5(³*⁶) = 1.5¹⁸.

It is appropriate to take a pulse by counting the heart rate for 30 seconds and multiplying by two when a rapid or irregular pulse is suspected, or when it is difficult to count the pulse for a full minute.

Counting the heart rate for a full minute is the most accurate way to determine the heart rate. However, there are situations when it may be more appropriate to count the heart rate for 30 seconds and multiply by two.

For example, if a person's pulse is rapid or irregular, it may be difficult to accurately count the pulse for a full minute. In such cases, it may be more appropriate to count the pulse for 30 seconds and multiply by two to get an estimate of the heart rate.

Another situation where it may be appropriate to count the pulse for 30 seconds is when time is limited, such as in an emergency situation. In such cases, counting the pulse for 30 seconds and multiplying by two can provide a quick estimate of the heart rate.

However, it is important to note that counting the pulse for 30 seconds and multiplying by two may not be as accurate as counting the pulse for a full minute.

Therefore, if possible, it is recommended to count the pulse for a full minute to obtain the most accurate measurement of the heart rate.

The integral of 5cos(5x)dx using trigonometric integrals is equal to sin(5x) + C, where C is the constant of integration.

To evaluate the integral ∫5cos(5x)dx using trigonometric integrals,

we can use the following trigonometric identity,

∫cos(ax)dx = (1/a)sin(ax) + C

Here value of a is equal to 5.

Applying this identity to our integral, we have,

∫5cos(5x)dx

= (5/5)sin(5x) + C

= sin(5x) + C

where C is the constant of integration.

Therefore, the integral of 5cos(5x)dx is sin(5x) + C, where C is the constant of integration.
