Answer:

[tex]\huge\boxed{\sf R. 16.75}[/tex]

Step-by-step explanation:

*Assuming commas are used for decimals.

2.6 kg potatoes = R 13.20

Divide 2.6 to both sides

1 kg potatoes = R 13.20/2.6

1 kg potatoes = R 5.1

Multiply 3.3 to both sides

3.3 kg potatoes = R 5.1 × 3.3

3.3 kg potatoes = R 16.75

The table that represents an exponential function of the form y = [tex]b^{x}[/tex] when 0 < b < 1 is Table - 2. See the attached tables.

A function is exponential when its value is a constant that is raised to the power of the argument. This is so especially when the function of the constant is e.

Recall that the exponential function y = [tex]b^{x}[/tex] given that 0 < b < 1. Notice that the table number 2 see to the exponential function that has the following form:

y(x) = (1/3)ˣ

substituting the values of x into the equation, we have:

y(-3) = (1/3) ⁻³ = 27

x = -2; thus

y(-2) =  (1/3) ⁻³ = 9

x = -1; thus

y(-1) =  (1/3) ⁻³ = 3

x = 0; thus

y(0) =  (1/3) ⁻⁰ = 1

x = 1; thus

y(1) =  (1/3) ¹ = 1/3

x = 2; thus

y(2) =  (1/3) ⁻² = 1/9

x = 3; thus

y(3) =  (1/3) ⁻³ = 1/27

Therefore, according to the obtained values, one can summarize that the table that depicts the exponential function y  = bˣ is table 2.

Since PQ is perpendicular to RS, the angles PQR and PQS would be right angles, and right anglers are congruent, so <PQR ≅ <PQS. We are given that <R and <S are the same length, so they are congruent(<R ≅ <S). Since PQ is included in both triangles and it is the same length as itself(PQ ≅ PQ).

We have three congruent parts, two angles and one side. Therefore, using AAS, ΔPQR ≅ ΔPQS

The product of the functions is 3x³ - 6x² + 5x - 10

Composite functions

Given the following functions expressed as

f(x) = 3x² + 5

g(x) = x - 2

In order to determine the value of (fg)x, we will take the product of the functions as shown

f(x)g(x) = 3x²+5)(x-2)

Expand to have;

f(x)g(x) = 3x³ - 6x² + 5x - 10

Hence the product of the functions is 3x³ - 6x² + 5x - 10

Answer:

the leftover piece of ribbon is 5 3/4 feet long.

Step-by-step explanation:

if she has 7 1/2 feet of ribbon, and she removes (by cutting it off) 1 3/4 feet of ribbon.

So, if we set up this scenario like a math problem, we can write it as this:

7 1/2 feet of ribbon - 1 3/4 feet of ribbon = remaining ribbon

[ - = take away]

so, we are solving the equation:

7 1/2 - 1 3/4

To solve this, it is easiest to make the fractions have the same denominators

1 / 2 is equal to 2 / 4

However, 2/4 is less than 3/4, so we need to make this fraction a larger number.

To do this, we can take away 1 foot from the 7, and write it as if it were fourths

1 [foot] = 4/4 quarter foot

So, we can add 4/4 + 2/4 = 6/4

Now, we can re-write our situation.

6 6/4  -   1 3/4 = left over ribbon

   6      6/4

-   1       3/4

__________

   5      3/4

So, the leftover piece of ribbon is 5 3/4 feet long.

Hope this helps!

They are asking you to combine like terms. The total should be 180.

Givens

2 angles

Total 180

Solution

8x - 3 + 4x + 3 = 180        The threes cancel. So add what's left. They are of opposite signs, so they cancel.

12x = 180                           Divide both sides by 12

12x/12 = 180 /12                        

x = 15

In this question we are provided with the two angles that is 8x - 3 and 4x + 3 respectively. It is also given that the sum of this two angles is 180°.

To solve this question we will combine the like terms and there sum must be 180°.
