The function that gives the shares received by a post whereby each friend

shares the post a constant multiple of times each day is exponential.

The given table of values for Ben's social media post is presented as follows;

\(\begin{tabular}{|c|c|}Day&Number of shares\\0&2\\1&6\\2&18\end{array}\right]\)

The number of shares triples everyday, therefore, the number of shares form a geometric progression, with a common ratio of r = 3, and a first term of a = 2

The function for the number of shares of Ben's post is, tₙ  = a·rⁿ

Which gives;

Number of friends Carter shared his post with = 10 friends

Number of people each of the 10 friends shared with each day = 2 people

The exponential function for number of shares received by Carter is therefore, tₙ = 10×2ⁿ

Tom wants to buy 3( 3)/(4) cups of almonds. There are ( 5)/(8) of a cup of almonds in each package.  Tom should buy 24 packages of almonds to obtain 3(3/4) cups of almonds.

To find the number of packages, we first convert the mixed number 3(3/4) to an improper fraction. The improper fraction equivalent of 3(3/4) is (4*3+3)/4 = 15/4 cups of almonds.

Next, we divide the total cups needed (15/4) by the amount of almonds in each package, which is (5/8) of a cup. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. So, (15/4) / (5/8) becomes (15/4) * (8/5).

Simplifying the multiplication of fractions, we cancel out common factors between the numerator of the first fraction and the denominator of the second fraction. After cancellation, we have (3/1) * (8/1) = 24.

Answer:

11 THE ANSWER IS 11 ELEVEN

When two consecutive whole numbers are randomly selected, the probability that one of them is a multiple of 4 is 1/2.

To find the probability that one of the two consecutive whole numbers selected is a multiple of 4, follow these steps:
Identify the pattern of multiples of 4.
Multiples of 4 follow this pattern: 4, 8, 12, 16, and so on.
Observe the consecutive whole numbers that include a multiple of 4.
When selecting two consecutive whole numbers, they will be in one of the following forms:
a) (Multiple of 4) and (Multiple of 4 + 1)
b) (Multiple of 4 - 1) and (Multiple of 4)
Determine the probability of each form.
a) For every 4 consecutive whole numbers, there is one pair of the form (Multiple of 4) and (Multiple of 4 + 1). Thus, the probability of this form is 1/4.
b) Similarly, for every 4 consecutive whole numbers, there is one pair of the form (Multiple of 4 - 1) and (Multiple of 4). The probability of this form is also 1/4.
Calculate the total probability.
The total probability is the sum of the probabilities of both forms:
Total Probability = (Probability of form a) + (Probability of form b)
Total Probability = (1/4) + (1/4) = 2/4
Simplify the fraction.
The total probability can be simplified to 1/2.
So, when two consecutive whole numbers are randomly selected, the probability that one of them is a multiple of 4 is 1/2.

The value of R(x) term is 36.

We are given that;

The equation x³ + 2x² - 72x - 28

Now,

We divide the first term, 8x, by the first term of d(x), which is x. This gives us 8, which is the third term of Q(x). We write 8 above the division bar and multiply it by d(x), which gives us 8x - 64. We subtract this from the new dividend, which gives us 36.

Since we cannot divide 36 by x-8 any further, we stop here and write 36 as the remainder R(x).

   x² + 10x + 8

  _______________

x-8 | x³ + 2x² - 72x - 28

    - (x³ - 8x²)

    -------------

        10x² - 72x

      - (10x² -80x)

      -------------

             8x -28

           - (8x -64)

           ----------

                36

Q(x) = x² + 10x + 8 and R(x) = 36.

Answer: i may be wrong but is it 4?

The solution of the given simultaneous equations is x = 3 and y = 5.

The given equations are:

3x + 2y = 19

x + 2y = 13

To solve them using the elimination method, we need to eliminate one variable from the equations. In this case, we can eliminate y by subtracting the second equation from the first equation, as follows:

(3x + 2y) - (x + 2y) = 19 - 13

Simplifying the left-hand side, we get:

2x = 6

Dividing both sides by 2, we obtain:

x = 3

Now that we have found the value of x, we can substitute it back into one of the original equations to find the value of y. Let's substitute it into the second equation:

x + 2y = 13

3 + 2y = 13

Subtracting 3 from both sides, we get:

2y = 10

Dividing both sides by 2, we obtain:

y = 5

To prepare a 1000 mL of a 1:32 ratio bleach solution, you would need to mix 31.25 mL of bleach with 968.75 mL of water.

To calculate the amount of bleach needed to make a 1000 mL solution, we can set up the following proportion:

1 part bleach / 32 parts water = X mL bleach / 1000 mL total solution

Cross-multiplying, we get:

32X = 1000

Solving for X, we get:

X = 1000 / 32 = 31.25 mL of bleach

To determine the number of tons of metal per year needed for Machine A to be favored over Machine B, we compare their costs. Machine A costs $323,000 with an annual operating cost of $2.40/ton, while Machine B costs $178,000 with an annual operating cost of $8.00/ton. The machines have useful lives of 10 years and 6 years, respectively, and the minimum attractive rate of return (MARR) is 18% per year.

By calculating the equivalent annual costs (EAC) for each machine using the given formula and comparing them, we can determine the point at which Machine A becomes more favorable. However, specific values for the discounting factors and the tons per year needed are missing, making it impossible to provide an exact answer.

Using an exponential function, it is found that f(5.5) = 19.8.

An exponential function is a function in which the growth rate is a percentage, modeled by:

\(y = ab^x\)

In which:

f(3.5) = 25 means that:

\(ab^{3.5} = 25\)

\(a = \frac{25}{b^{3.5}}\)

f(8.5) = 14 means that:

\(ab^{8.5} = 14\)

Hence:

\(\frac{25}{b^{3.5}} \times b^{8.5} = 14\)

\(25b^5 = 14\)

\(b = \sqrt[5]{\frac{14}{25}}\)

\(b = 0.89\)

\(a = \frac{25}{0.89^{3.5}} = 37.59\)

Hence, the function is given by:

\(y = 37.59(0.89)^x\)

Then, when x = 5.5:

\(f(5.5) = 37.59(0.89)^{5.5} = 19.8\)

When counting the significant figures in a number, the first rule is that any digit that isn't a zero would be considered a significant digit.

Zeros that are trailing in a number however, and are not considered decimals, are not counted as significant digits. This means that both the 2 number 2s in the figure will be significant figures.

Weight of the John increased by 10.71 percent as he is weighing 140 pounds to 155 pounds.

As given in the question,

Original weight of John is equal to 140 pounds

John's changed weight is equal to 155 pounds

155 is greater than 140 pounds

Increase in John's weight.

Change in weight = Increased weight - actual weight

Percent of change in John's increased weight

= [ | change in weight| / Actual weight ] × 100

=  [(155 - 140 ) / 140] × 100

= (15 / 140)× 100

Answer:

the third option

Step-by-step explanation:

what does that mean ?

to "rationalize" it is to transform it into a rational number (that is a number that can be described as a/b, and is not an endless sequence of digits after the decimal point without a repeating pattern).

a square root of a not square number is irrational (not rational).

so, what this question is asking us to get rid of the square root part in the denominator (the bottom part).

for this we need to multiply to and bottom with the same expression (to keep the whole value of the quotient the same) that, when multiplied at the bottom, eliminates the square root.

what can I multiply a square root with to eliminate the square root ? the square root again - we are squaring the square root.

so, what works for 9 - sqrt(14) as factor ?

we cannot just square this as

(9- sqrt(14))² = 81 -2sqrt(14) + 14

we still have the square root included.

but remember the little trick :

(a+b)(a-b) = a² - b²

without any mixed elements.

so, we need to multiply (9-sqrt(14)) by (9+sqrt(14)) to get

81-14 = 67 which is a rational number.

therefore, the third answer option is correct.

follow the rule

\(\\ \sf\longmapsto \dfrac{a+b}{c-d}\)

To rationalize the above fraction we need to change the sign of denominator patt and multiply with both numerator and denominator

Like

\(\\ \sf\longmapsto \dfrac{a+b(c+d)}{(c-d)(c-d)}\)

Here correct option is C
