The large box weighs 18.75 kg, and the small box weighs 15.75 kg.

We have,

Let's assume the weight of a large box is L kg, and the weight of a small box is S kg.

According to the given information, we can create the following equations:

Equation 1: 3L + 5S = 135 (1st delivery)

Equation 2: 9L + 7S = 279 (2nd delivery)

To solve these equations, we can use a method called "elimination" or "substitution."

Multiply Equation 1 by 3 and Equation 2 by 1, so that the coefficients of L will be the same:

Equation 1: 9L + 15S = 405

Equation 2: 9L + 7S = 279

Now, we can subtract Equation 2 from Equation 1 to eliminate L:

(9L + 15S) - (9L + 7S) = 405 - 279

Simplifying:

8S = 126

Divide both sides of the equation by 8:

S = 126/8 = 15.75

So, the weight of a small box (S) is 15.75 kg.

Now,

substitute the value of S into Equation 1 to find the weight of a large box (L):

3L + 5(15.75) = 135

3L + 78.75 = 135

3L = 135 - 78.75

3L = 56.25

Divide both sides of the equation by 3:

L = 56.25/3 = 18.75

So,

The weight of a large box (L) is 18.75 kg.

Thus,

The large box weighs 18.75 kg, and the small box weighs 15.75 kg.

Red: 0.3469

Blue: 0.2449

Green: 0.0816

Yellow: 0.2449

Purple: 0.0816

To calculate the probability of the spinner landing on a specific color, we need to divide the frequency of that color by the total number of spins.

Given the spinner results:

Answer:

259.8

Step-by-step explanation:

The apothem of a regular polygon is a segment whose endpoints are the center of the polygon and the midpoint of one side.

Look at the bottom of the drawing. The dimension 17.32 is the distance between two opposite parallel sides of the regular hexagon base. If you draw a segment that is parallel to two opposite sides of the hexagon and passes through the center of the hexagon, it is twice the length of the apothem.

Here,

apothem = 17.32/2 = 8.66

If you divide the hexagon into 6 congruent triangles, each triangle is an equilateral triangle. Then the side of the hexagon measures 10.

A = 1/2 pa

p = perimeter = 6 × side length = 6 × 10

a = apothem = 8.66

A = 1/2 × (6 × 10) × 8.66

The conic section of the equation 4x² + 9x +4y² - 36y - 125 = 0 is a circle

The given equation is

4x² + 9xy + 4y² - 36y - 125 =0

The above equation is an illustration of a circle equation

The standard form of a circle equation is

(x - a)² + (y - b)² = r²

Where

(a, b) is the center

r is the radius

While the general form of the equation is

ax² + fx + by² + gy + c =0

Where c is a constant

Recall that, we have

4x² + 9x + 4y² - 36y - 125 =0

This is the general form

We can convert to the standard form as follows

Divide through by 4

x² + 2.25x + y² - 9y - 31.25 =0

Next, we complete the square of the x-terms and the y-terms

For the x-terms, we have

x² + 2.25x = x² + 2.25x + (2.25/2)² - (2.25/2)²

x² + 2.25x = (x + 2.25/2)² - (2.25/2)²

For the y-terms, we have

y² - 9y = y² - 9y + (9/2)² - (9/2)²

y² - 9y = (y - 9/2)² - (9/2)²

Substitute the new x and y terms

So, x² + 2.25x + y² - 9y - 31.25 = 0 becomes

(x + 2.25/2)² - (2.25/2)² + (y - 9/2)² - (9/2)²- 31.25 =0

Evaluate the sum of like terms

(x + 2.25/2)² + (y - 9/2)² - 3377/64 = 0

So, we have

(x + 9/8)² + (y - 9/2)² = 3377/64

Using the order of operations (PEMDAS) we first simplify the multiplication before subtracting from 2:

2 - (-0.5 x 47)

= 2 - (-23.5)

When subtracting a negative number, we can think of it as adding the positive value. Therefore, we can rewrite the expression as:

2 + 23.5

Question

which value is a solution  A- 2-( -0.5x47)

Answer:

  2a. maximum: (1, 8); minimum: (3, 0)

  2b. point of inflection: (2, 4)

  3.  a = 1/4

Step-by-step explanation:

You want the extrema and the point of inflection of f(x) = 2x³ -12x² +18x, and you want the value of 'a' that makes the end behavior a horizontal asymptote at y = 1.

The cubic function f(x) = 2x³ -12x² +18x has derivative ...

  f'(x) = 6x² -24x +18 = 6(x² -4x +3) = 6(x -1)(x -3)

The derivative will be zero at x = 1 and 3. These are the x-coordinates of the extrema of f(x).

The values of f(x) at those points are ...

  f(x) = 2x((x -6)x +9)

  f(1) = 2·1((1 -6)1 +9) = 2(-5 +9) = 8

  f(3) = 2·3(3 -6)·3 +9 = 6(-9 +9) = 0

The leading coefficient is positive, so the leftmost portion of the curve is increasing. The maximum will be at the leftmost turning point. The minimum is the other one (rightmost).

The maximum is (1, 8); the minimum is (3, 0).

The point of inflection is the midpoint between the extrema of a cubic:

  ((1, 8) +(3, 0))/2 = (2, 4) . . . . point of inflection

You want the limit as x → -∞ of ((x -2)(3x² +5) -4ax³)/(8ax³ +5x -1) to be 1.

The ratio of leading terms of the numerator and denominator is ...

  (3 -4a)x³/(8ax³) = 1

This requires ...

  3 -4a = 8a   ⇒   3 = 12a   ⇒   a = 1/4

The value of 'a' that makes the limit be 1 is 1/4.

__

Additional comments

A cubic is symmetrical about its point of inflection, so the point of inflection will be equidistant from the extrema, their midpoint. When the leading coefficient is positive, the function is increasing everywhere except between the local extrema. (The first attachment has a graph of the derivative, for reference.)

The end behavior of a rational function of equal numerator and denominator degree is the ratio of the leading coefficients.
