The possible values of angles A and C are;

60° and 70° or 55° and 75°

An acute triangle is a triangle that has all the measures of its angles to be less than 90°.  This means that none of the angles is greater than 90°

Since sum of the angles in a triangle is equal to 180°, then it means that;

∠A + ∠B + ∠C = 180°

We are given that;

∠B = 50°

Thus;

50° + ∠A + ∠C = 180°

∠A + ∠C = 180° - 50°

∠A + ∠C = 130°

It should be noted that all the angles of the acute triangle are also different.

Thus, the possible values of A and C are 60° and 70° or 55° and 75° because their sum must be equal to 130°

The expression ∛(a)⁷  raised to a single rational exponent is  [tex]a^{\frac{7}{3} }[/tex] .

A rational number is one that can be defined as the ratio or fraction a/b of two numbers, where a and b are the numerator and denominator, respectively. Here the integer numbers a and b are co prime numbers.

For example 8/7 is a rational number and all integers are rational numbers.

Any combination of terms that have undergone operations like multiplication,addition, subtraction, division is known as an algebraic expression.

it is given that the expression is of the form ∛(a)⁷ .

We know that the n-th root of a variable x ([tex]\sqrt[n]{x}[/tex]) can also be written as

[tex]x^{\frac{1}{n} }[/tex].

Therefore  ∛(a) can be written as [tex]a^{\frac{1}{3} }[/tex] . Now the complete expression is ∛(a)⁷.

So [tex](a^{\frac{1}{3} })^7=a^{\frac{7}{3} }[/tex] and we know that 7/3 is a rational number.

Answer:

Step-by-step explanation:

If the two functions be f(x) = 3x² - 11x - 4 and g(x) = 3x + 1 then

(fg)(x) = f(x)g(x) = [tex]$$9x^3[/tex] - 30x² - 23x - 4

(f/g)(x) = f(x)/g(x) = x - 4

Function operations are the rules we use to solve functions. There is a specific way to deal with function addition, multiplication, and division.

Function composition is a mathematical operation that takes two functions f and g and produces a function h = g f such that h(x) = g(f(x)). The function g is applied to the result of applying the function f to x in this operation.

Let the two functions be f(x) = 3x² - 11x - 4 and g(x) = 3x + 1.

(fg)(x) = f(x)g(x)

= (3x² - 11x - 4) (3x + 1)

simplifying the above equation, we get

= 3x² [tex]*[/tex] 3x + 3x² [tex]*[/tex] 1 - 11x [tex]*[/tex] 3x - 11x [tex]*[/tex] 1 - 4 [tex]*[/tex] 3x - 4 [tex]*[/tex] 1

= [tex]$$9x^3[/tex] - 30x² - 23x - 4

Therefore, (fg)(x) = f(x)g(x) = [tex]$$9x^3[/tex] - 30x² - 23x - 4

(f/g)(x) = f(x)/g(x)

Where, f(x) = 3x² - 11x - 4 and g(x) = 3x + 1.

f(x)/g(x) =  (3x² - 11x - 4)/(3x + 1)

= [(3x + 1)(x - 4)]/(3x + 1)

canceling the common factors we get

= x - 4

Therefore, f(x)/g(x) = x - 4

The division of f (x) and g (x) is x - 1 and the domain is  [ 1 , ∞ ].

Given,

f (x) = x - 2

g (x) = x ² - 3 x + 2

The question states to find the division of the function f, that is, f (x) = x - 2, and function g, that is, g (x) = x ² - 3 x + 2

Performing the division operation on these functions is just like simple division.

This implies, dividing the two functions f (x) and g (x), we get

g (x) / f (x) = x² - 3x + 2 / x - 2

            x - 1

        ___________

x - 2 |   x² - 3x + 2

           x² - 2x

         ____________

                   -x + 2

                   -x + 2

         ____________

                           0

=> g (x) / f (x) = x - 1

This implies that the division of the two functions f (x) and g (x) gives x - 1

To find the domain :

y =  x - 1

=> x ≥ 1

=> Domain = [ 1 , ∞ ]  

Therefore, we get the division of f (x) and g (x) as x - 1 and the domain as  [ 1 , ∞ ].

The width of the rectangle is: 3 meters.

Perimeter of a rectangle is determined using the formula:

Perimeter = 2(length + width)

Given the parameters below:

Width of the rectangle = w meters

Length of the rectangle = 2w - 3 meters

Perimeter of the rectangle = 24 meters

Therefore:

2((2w - 3) + w) = 24

Solve for w (width of the rectangle)

2((2w - 3 + w) = 24

2(3w - 3) = 24

6w - 6 = 24

6w = 24 - 6

6w = 18

6w/6 = 18/6

w = 3

Therefore, the width of the rectangle is: 3 meters.

Data of different sizes can be easily arranged with histograms, but not with stem-and-leaf diagrams. This is a drawback.

Stem-and-leaf charts often include the original data values while histograms do not. This is a crucial advantage the former has over the latter.

The primary benefit of stem-and-leaf charts over histograms is that they display the original data values.

In contrast to stem-and-leaf charts, which lack this capability, histograms make it straightforward to organize data of various sizes. This is a serious disadvantage.

The only one that is not  part of the process for copying ∠CAB is; Option D: Label the intersection of the arc and the new line C'.

The steps for constructing a copy of an angle using only a compass and a straightedge are as follows;

Step 1: Mark the point that will be the vertex of the new angle, and label it P.

Step 2: Draw a ray from P in any direction, with any length. This ray will be one of the sides of the new angle.

Step 3: Place the compass point on the vertex of the original angle, and adjust the compass width to a convenient size.

Step 4: Use the compass to draw an arc intersecting both rays of the original angle at two points, J and K.

Step 5: Move the compass (without changing the width) to point P, and make an arc intersecting the existing ray of the angle. Mark the intersection point, and label it M.

Step 6: Set the compass point on the original angle at point J, and set its width to the length of line segment JK.

Step 7: Move the compass point to M on the new angle, and draw an arc cutting the previous arc. Mark the intersection point and label it L.

Answer:

Step-by-step explanation:

The correct option for the end behaviour of function is option C. As x approaches positive infinity, g(x) approaches positive infinity.

We have been assigned the following function:

g(x) = 1/2|x - 3| - 7

Behavior at the end:  As x approaches negative and positive infinity, the limit of g(x) is reached.

Infinity minus one:

lim g(x) =   lim      1/2|x - 3| - 7

x → -∞          x → -∞

lim g(x) =  1/2|-∞ - 3| - 7   = | -∞ |  = ∞

x → -∞        

Thus, the negative end behaviour is ∞ .

Infinity plus one:

lim g(x) =   lim      1/2|x - 3| - 7

x → ∞          x → ∞

lim g(x) =  1/2|∞ - 3| - 7   = | ∞ |  = ∞
