Answer: OPTION C

Step-by-step explanation:

 To express a polynomial in Standard form, you need to see the exponent of each term of the polynomial and then order the polynomial from highest exponent to lowest exponent.

Therefore, for the polynomial  [tex]5a^2 + 3a^3 + 1[/tex], you get:

  [tex]3a^3 +5a^2 +1[/tex]

The highest exponent gives you the degree of the polynomial. In this case, the highest exponent is 3, then it is a polynomial of degree 3 or a cubic polynomial.

When a polynomial has three terms, is called "trinomial". Since this polynomial has three terms, it is a trinomial.

Therefore, the you can classify it as:

Cubic trinomial

For this case we must find the inverse of the following function:

[tex]f (x) = \sqrt [3] {x + 12}[/tex]

For this, we follow the steps below:

Replace f (x) with y:

[tex]y = \sqrt [3] {x + 12}[/tex]

We exchange the variables:

[tex]x = \sqrt [3] {y + 12}[/tex]

We solve the equation for "and":

[tex]\sqrt [3] {y + 12} = x[/tex]

We raise both sides of the equation to the cube to eliminate the root:

[tex](\sqrt [3] {y + 12}) = x ^ 3\\y + 12 = x ^ 3[/tex]

We subtract 12 on both sides of the equation:

[tex]y = x ^ 3-12[/tex]

Thus, the inverse function is:

[tex]f ^ {- 1} = x ^ 3-12[/tex]

Answer:

Option B

Option: B is the correct answer.

       B.    [tex]f^{-1}(x)=x^3-12[/tex]

The inverse function f(x) is calculated in the following steps.

The function f(x) is given by:

[tex]f(x)=\sqrt[3]{x+12}[/tex]

Now, we keep:

[tex]f(x)=y\\\\i.e.\\\\y=\sqrt[3]{x+12}[/tex]

Now, we interchange x and y

[tex]x=\sqrt[3]{y+12}[/tex]

Now, on taking cube on both side of the equation we have:

Step-by-step explanation:

Part 1) Solve the system by elimination

Let

x----> the cost per can of grape juice

y----> the cost per can of apple juice

we know that

[tex]6x+4y=13.10[/tex] -----> equation A

[tex]4x+6y=13.10+0.60[/tex]

[tex]4x+6y=13.70[/tex]  -----> equation B

Solve the system by elimination

Multiply the equation A by -6 both sides

[tex]-36x-24y=-78.6[/tex] -------> equation C

Multiply the equation B by 4 both sides

[tex]16x+24y=54.8[/tex] -------> equation D

[tex]-36x-24y=-78.6\\16x+24y=54.8\\----------\\-36x+16x=-78.6+54.5\\-20x=-23.8\\x=1.19[/tex]

Substitute the value of x in the equation A

[tex]6(1.19)+4y=13.10[/tex]

[tex]4y=5.96[/tex]

[tex]y=1.49[/tex]

therefore

The cost  per can of grape juice is [tex]\$1.19[/tex]

The cost per can of apple juice is [tex]\$1.49[/tex]

Part 2) Solve the system by substitution

Let

(x-5)(2x-1) (-2x+1)(-x+5)=0 and (-2x+1)(x-5)=0 quadratic equation have  as solution set.

Answer:

well i got some HOPE THIS WILL HELP

Step-by-step explanation:

To find the solution set of a factored quadratic equation, you should set each one of the factors equal to zero and solve for .

Lets take our first quadratic equation (x+1/2)(x-5)=0 and apply this. First we are our factors equal to zero  and ; next we are going to sole for  in each factor to find the solution set:

and , so the solution set for the quadratic equation (x+1/2)(x-5)=0 is 

Lets do the same for our next one (x-5)(2x-1)=0

and

So, the solution set for the quadratic equation (x-5)(2x-1)=0 is 

Next one (x+5)(2x-1)=0

and 

So, the solution set for the quadratic equation (x+5)(2x-1)=0 is 

Next one (-2x+1)(-x+5)=0

and

So, the solution set for the quadratic equation (-2x+1)(-x+5)=0 is : therefore, we are going the select this one.

Next one (x+1/2)(x+5)=0

and

So, the solution set for the quadratic equation (x+1/2)(x+5)=0 is 

Finally, our last one (-2x+1)(x-5)=0

and

So, the solution set for the quadratic equation (-2x+1)(x-5)=0 is ; this is also a correct answer, make sure to select this one too.

We can conclude that both (-2x+1)(-x+5)=0 and (-2x+1)(x-5)=0 quadratic equation have  as solution set.

Rewrite both fractions so they have a common denominator:

-3/6 = -21/42

-5/7 = -30/42

Now you have -21/42 - 30/42

Now subtract to get:

-51/42 which reduces to -17/14 = -1 3/14

The simplification of the expression is,-17/14. The simplification is done by applying the mathematical operation step by step.

Simplification usually entails doing out the expression's pending processes.

The given expression is

(-3/6) –(5/7)

The LCM of the 6 and 7 is 42 so  rewrite the equation as;

(-3×7)/42 – (5×6)/7

(-21/42)-30/42

-51/42

Divide by 3 from the numerator and denominator we get;

-17/14

Hence, the simplification of the expression is,-17/14

There are 3,024 different ways the coach can choose players for first base, second base, third base, and shortstop from a team of 9 players.

Since the positions are distinct (first base, second base, third base, and shortstop), and each position can only be filled by one player, we can use the permutation formula to calculate the number of arrangements.

The coach has 9 players to choose from for the first position.

After selecting one player for first base, there remain 8 players for the second position, 7 players for the third position, and 6 players for shortstop.

The total number of different ways the coach can choose players for the four positions is obtained by multiplying these numbers:

9 x 8 x 7 x 6 = 3,024

To simplify a complex fraction, multiply both the numerator and the denominator by the same factor to eliminate fraction in the denominator, cancel common factors and follow rules of algebra to maintain equality.

To evaluate and simplify a complex fraction, we can use a strategy that involves multiplying the numerator and denominator by the same factor. For example, if our complex fraction had a denominator of 1/2, we could multiply both the numerator and the denominator by 2 to eliminate the fraction in the denominator. This approach ensures the units or variables cancel out where appropriate, leaving us with a simpler expression. When working with fractions, common factors can be identified and cancelled to simplify the fraction further. Always remember that fractions represent division, so when simplifying, divide the digit term of the numerator by that of the denominator and subtract the exponentials accordingly. This process is governed by the rules of algebra, maintaining the equality of the expression.

Step-by-step explanation:

The mean absolute deviation of the data set is approximately 3.09.

The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations in a data set and their mean.

To calculate the MAD, you first need to find the mean of the data set. In this case, the mean is 31.375.

Then, you calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).

Once you have calculated the absolute deviation of each data point, you find the average of those absolute deviations. This is the mean absolute deviation.

In the example data set, the mean absolute deviation is approximately 3.

Find the mean of the data set: (21 + 22 + 24 + 26 + 27 + 28 + 20 + 30) / 8 = 31.375

Calculate the absolute deviation of each data point from the mean. For example, the absolute deviation of the first data point (21) is 10.375 (|21 - 31.375|).

Add up the absolute deviations of all the data points. In this case, the sum of the absolute deviations is 24.75.

Divide the sum of the absolute deviations by the number of data points to find the mean absolute deviation. In this case, the mean absolute deviation is 24.75 / 8 = 3.09375.

Therefore, the mean absolute deviation of the data set is approximately 3.09.

Step 1: Find the total area. Since it is a square all the sides are 12 ft so multiply 12 by 12

12 x 12 = 144

^^^This is the total area including the area around the pool. We just need the are of the pool

Step 2: Outside of the pool there are four little 2 ft by 2 ft squares that aren't part of pool, and therefore won't need to be covered. The area of these 2 ft by 2 ft square is 4ft (2 times 2 is 4). Since there are 4 of these squares we multiply 4 by 4 to get 16. This means that 16 ft of the 144 ft we found previously are not part of the pool and we must subtract 16 from 144 to get the total pool area

144 - 16 = 128

The probability of drawing two white socks from the drawer is 2/27.

To find the probability that both socks drawn are white, we need to find the probability of drawing a white sock on the first draw and then drawing another white sock on the second draw.

There are a total of 9 socks in the drawer (4 black, 3 white, and 2 red).

The probability of drawing a white sock on the first draw is 3/9 (3 white socks out of 9 total socks).

After replacing the first sock, the total number of socks remains the same, but the number of white socks decreases to 2. So the probability of drawing a white sock on the second draw is 2/9.

Now, to find the probability of both events happening, we multiply the probabilities together: P(First white sock) * P(Second white sock) = (3/9) * (2/9) = 6/81 = 2/27.

Therefore, the probability that both socks drawn are white is 2/27.
