The required system hence becomes

3x-y+4>0,

y + 6 > (x + 2)²

When the symbols “>”, “<”, “≥”, “≤”,  are used to connect two real numbers or algebraic expressions, that relationship is known as an inequality.

The Graph is given below of the given problem statement.

Observe that the parabola y=x² has vertex at (0,0) we can shift the vertex to (-2,-6) to get the parabola

y + 6 = (x + 2)²

And the inequality is

y + 6 > (x + 2)²

Hence, this parabola is as required by the problem.

And the line passing through (-3,-5) and (0,4) is

[tex]\frac{\left(y-4\right)}{\left(-5-4\right)}=\frac{\left(x\right)}{-3}[/tex]

The required inequality hence becomes

[tex]9[/tex] to the power of [tex]33 = 9^33 = 30 9031543826 3261236192[/tex]0641803529.

Step-by-step explanation:  As the exponent is a positive integer, exponentiation means a repeated multiplication:

9 to the 33rd power =[tex]{9*....*9}[/tex] 33times

The exponent of the number 9, 33, also called index or power, denotes how many times to multiply the base (9).

Thus, we can answer what is 9 to the 33rd power as

[tex]9[/tex] to the power of [tex]33 = 9^33 = 30 9031543826 3261236192[/tex]0641803529.

30903154382632612361920641803529.

The power of a numeral stands for how many multiples of the number there exist. The base of the number stands for the number itself and lives in front of the exponent. The exponent stands for the smaller number written above and to the right of the base. Positive exponents result in the base value existing multiplied by itself numerous times.

As the exponent exists as a positive integer, exponentiation signifies repeated multiplication.

9 to the 33rd power [tex]$=9* ........*9*[/tex] 33 times

The exponent of the number 9, 33, even named index or power, indicates how many times to multiply the base (9).

Therefore, we can answer what exists 9 to the 33rd power as 9 to the power of 33 = [tex]9^{33}[/tex] to the power of 30903154382632612361920641803529.

Answer:

So let start with 1/4 simplest form of that would be 9/4 and for 11/24 simplest would be just that so now we got 11/24 - 9/4 = 1/72

Step-by-step explanation:

11/24

4/9

now we do 11 x 9 equals 99 so now 4 x 24 = 96

now we take the two new denominators2 24 and 9

and we do 24 x 9 = 216 so now we got

99/216

96/216

now 99 - 96 is 3 so we got a new fraction

3/216 now we just simplify that  so we get 1/72

Using it's concept, the set of ordered pairs that represent a function are:

The set of ordered pairs that do not represent a function are:

A relation represents a function if each input X is mapped to only one output Y.

At (1,9), (-3,-2) (1,-4), input 1 is mapped to outputs 9 and -4, hence it is not a function.

At (0, 3), (0, 7), (4,0), input 0 is mapped to outputs 3 and 7, hence it is not a function.

For the other relations, each input is mapped to only one output, hence they are functions.

The step in which Yvonne first makes an error while solving the quadratic equation by completing the square in step 1.

A quadratic equation is an equation in which the highest power of the variable is two.

Yvonne is solving the quadratic equation, which is,

He is solving the above equation by completing the square.

The first step to solving this quadratic equation by completing the square is, Take the constant value 7 at the opposite side of the equation as,

6x² +24x = -7

Here, the number seven was a positive number, which we have changed to negative because this number brings the other side of the equation.

In the image attached below, the first step of  the Yvonne while solving the equation by completing the square is,

Step-by-step explanation:

Using the Poisson distribution, the probabilities are given as follows:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters are:

The mean is given as follows:

[tex]\mu = 10.6[/tex]

Hence the probability of no dandelions in an area of 1 m² is P(X = 0), hence:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-10.6}(10.6)^{0}}{(0)!} = e^{-10.6}[/tex]

The probability of at least one dandelion is:

[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - e^{-10.6}[/tex]

The probability of at most two dandelions is:

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

Then:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-10.6}(10.6)^{0}}{(0)!} = e^{-10.6}[/tex]

[tex]P(X = 1) = \frac{e^{-10.6}(10.6)^{1}}{(1)!} = 10.6e^{-10.6}[/tex]

[tex]P(X = 2) = \frac{e^{-10.6}(10.6)^{2}}{(2)!} = 56.18e^{-10.6}[/tex]

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = e^{-10.6} + 10.6e^{-10.6} + 56.18e^{-10.6} = 67.78e^{-10.6}[/tex]

A = Amount

P = Principal

d = percent

n = number of year

A=P(1-d/100)^n

A = 10,200(1-8/100)⁵

Considering the definition of least common multiple, this means that smallest number of packages of each they can buy is 60.

A number is a multiple of another when it contains it exactly n times. In other words, the multiples of a number are the ones you get when you multiply one number by another.

The least common multiple allows us to know what is the smallest number that is a multiple of a certain set of numbers.

One procedure for calculating the least common multiple is to break each number into prime factors. Then the common and uncommon factors are raised to the highest exponent, which must be multiplied.

To calculate the smallest number of packages of each they can buy, you calculate the least common multiple.

First, the decomposition of the numbers into prime factors is carried out:

15= 3×5

12= 2×2×3= 2²×3

Then, the least common multiple is calculated as 2²×3×5

Solving, the least common multiple between 12 and 15 is 60.

Finally, this means that smallest number of packages of each they can buy is 60.
