Answer:

Alisha's approach is simpler and less complicated

Step-by-step explanation:

Given:

(m^2*n^-3) / (m^6*n^-1)

Tyrone's approach.

(m^2*n^-3) / (m^6*n^-1)

(m^2*n^-3)^3 / (m^6*n^-1)^3

You can find the cube root of both the numerator and denominator in order to eliminate the third power

3√((m^2*n^-3)^3 / 3√(m^6*n^-1)^3

This will take us back to the original expression

(m^2*n^-3) / (m^6*n^-1)

= m^(2-6)*n^(-3+1)

= m^-4*n^-2

= 1/(m^4*n^2)

Alisha's approach.

(m^2*n^-3)/(m^6*n^-1)

= m^(2-6)*n^(-3+1)

= m^-4*n^-2

= 1/(m^4*n^2)

The approach of both of them are correct, however, Tyrone's approach will make the expression more complicated but they would still arrive at the same answer. 1/(m^4*n^2)

The density of the marble will be "0.18 kg/m³".

According to the question,

Volume of marbles,

By converting it into m, we get

Mass,

By converting it into kg, we get

As we know, the formula:

→ \(Density = \frac{Mass}{Volume}\)

By substituting the values, we get

→               \(= \frac{0.045}{0.25}\)

→               \(= 0.18 \ kg/m^3\)

The discriminant of ggg is negative.

The discriminant is a term used in mathematics to determine the nature of the solutions of a quadratic equation. For a quadratic equation in the form ax^2 + bx + c = 0, the discriminant is given by b^2 - 4ac. If the discriminant is negative, it means that the quadratic equation has no real solutions. In the context of ggg, since the discriminant is negative, it indicates that the quadratic equation associated with ggg does not have real solutions. This could imply that ggg is not a quadratic expression or that it represents a quadratic expression with complex solutions.

What are the possible values (positive, zero, or negative) for the discriminant of the quadratic equation represented by the function g(x)?

The area of \($a$ is $\boxed{1200}$\).

Consider the region $a$ in the complex plane that consists of all points $z$ such that both

$\frac{z}{40}$ and $\frac{40}{\overline{z}}$

have real and imaginary parts between $0$ and $1$, inclusive. We need to find the area of $a$.

First, let's simplify

$\frac{z}{40}$ and $\frac{40}{\overline{z}}$:

\($$\frac{z}{40} = \frac{x + yi}{40} = \frac{x}{40} + \frac{y}{40}i$$$$\frac{40}{\overline{z}} = \frac{40}{x - yi} = \frac{40(x + yi)}{x^2 + y^2} = \frac{40x}{x^2 + y^2} - \frac{40y}{x^2 + y^2}i$$For $\frac{z}{40}$\)

to have real and imaginary parts between $0$ and $1$, we need

$x \in [0, 40]$ and $y \in [0, 40]$.

For $\frac{40}{\overline{z}}$ to have real and imaginary parts between $0$ and $1$, we need $x^2 + y^2 \geq 40x$ (so that $\frac{40x}{x^2 + y^2} \in [0, 1]$) and $x^2 + y^2 \geq 40y$ (so that $\frac{-40y}{x^2 + y^2} \in [-1, 0]$). This simplifies to

\($(x - 20)^2 + y^2 \geq 20^2$.\)

We can plot these inequalities in the $xy$-plane to see that $a$ is a trapezoid with bases $40$ and $80$ and height $20$:The area of $a$ is the average of the lengths of the bases multiplied by the height:

\($$\frac{(40 + 80)}{2} \cdot 20 = 1200$$\)

Answer:

The simplified form is  \(\frac{6}{5x^{10} }\) ⇒ A

Step-by-step explanation:

Let us solve the question

∵ The expression is \(\sqrt{\frac{72x^{16}}{50x^{36}}}\)

→ At first, divide simplify the coefficient of the variable

∵ \(\frac{72}{50}=\frac{36}{25}\)

∵ 36 = 6 × 6 and 25 = 5 × 5

→ 6 and 5 repeated twice then the can go out the root one 6 and one 5

∴ \(\sqrt{\frac{36}{25}}=\frac{6}{5}\)

→ Let us use the exponent rule with division \(\frac{a^{m} }{a^{n}}=a^{m-n}\)

∵ \(\frac{x^{16}}{x^{36}}=x^{(16-36)}=x^{-20}\)

→ To cancel the root divide the power by 2

∵ -20 ÷ 2 = -10

∴ \(\sqrt{x^{-20}}=x^{-10}\)

∴  \(\sqrt{\frac{72x^{16}}{50x^{36}}}\) = \(\frac{6}{5}\) × \(x^{-10}\)

→ To change the power of x from (-) to (+) reciprocal x

∴ \(x^{-10}=\frac{1}{x^{10}}\)

∴  \(\sqrt{\frac{72x^{16}}{50x^{36}}}\) = \(\frac{6}{5x^{10} }\)

∴ The simplified form is  \(\frac{6}{5x^{10} }\)

Answer:

A) 0.889

B) 0.895

Step-by-step explanation:

Mean of 53.8 inches, and Standard deviation of 7.5 inches.

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

A) What is the probability that a randomly chosen child has a height of less than 62.95 inches?

For x < 62.95

z = 62.95 - 53.8/7.5

z = 1.22

Probabilityvalue from Z-Table:

P(x<62.95) = 0.88877

Approximately = 0.889

B) What is the probability that a randomly chosen child has a height of more than 44.4 inches?

For x > 44.4 inches

z = 44.4 - 53.8/7.5

z = -1.25333

Probability value from Z-Table:

P(x<44.4) = 0.10504

P(x>44.4) = 1 - P(x<44.4) = 0.89496

Approximately = 0.895

The average rate of change of the function over the interval -2 ≤ x ≤ 2 is 12.

To find the average rate of change of the function over the interval -2 ≤ x ≤ 2, we need to calculate the difference in function values divided by the difference in x-values.

First, let's find the value of the function at the endpoints of the interval:

f(-2) = (-2)²(3(-2) - 2) = 4(-6 - 2) = 4(-8) = -32

f(2) = (2)²(3(2) - 2) = 4(6 - 2) = 4(4) = 16

Now, we can calculate the difference in function values and x-values:

Δy = f(2) - f(-2) = 16 - (-32) = 48

Δx = 2 - (-2) = 4

The average rate of change is given by Δy/Δx:

Average rate of change = 48/4 = 12

Therefore, the average rate of change of the function over the interval -2 ≤ x ≤ 2 is 12.

Answer:

A

Step-by-step explanation:

there is a common ratio between consecutive terms , that is

- 12 ÷ - 3 = - 48 ÷ - 12 = - 192 ÷ - 48 = 4

this indicates the sequence is geometric with nth term

\(a_{n}\) = a₁ \(r^{n-1}\)

where a₁ is the first term and r the common ratio

here a₁ = - 3 and r = 4 , then

Answer:

Kendra has 10 dimes and 30 quarters.

Step-by-step explanation:

From the information given and considering that a dime is $0.10 and a quarter  is $0.25, you can write the following equations:

0.10x+0.25y=8.50 (1)

y=3x (2)

x is the number of dimes

y is the amount of quarters

First, you can replace 2 in 1 and solve for x:

0.10x+0.25(3x)=8.50

0.10x+0.75x=8.50

0.85x=8.50

x=8.50/0.85

x=10

Then, you can replace the value of x in 2 to find the value of y:

y=3*10

y=30

According to this, the answer is that Kendra has 10 dimes and 30 quarters.
