Let : A = ( - 2 , - 6 ) & B = ( 3 , 9 )

[tex]d = distance \: \: between \: \: points \\ [/tex]

[tex]d = \sqrt{ ( \: {y(B) - y(A) } \: )^{2} + ( \: { x(B) - x(A) } \: )^{2} } \\ [/tex]

[tex]d = \sqrt{ ( \: {9 - ( - 6)} \: )^{2} + ( \: {3 - ( - 2)} \: )^{2} } \\ [/tex]

[tex]d = \sqrt{ ( \: {9 + 6} \: )^{2} + ( \: {3 + 2} \: )^{2} } \\ [/tex]

[tex]d = \sqrt{ {15}^{2} + {5}^{2} } [/tex]

[tex]d = \sqrt{225 + 25} [/tex]

[tex]d = \sqrt{250} [/tex]

[tex]d = \sqrt{25 \times 10} [/tex]

[tex]d = \sqrt{ {5}^{2} \times 10 } [/tex]

[tex]d = 5 \sqrt{10} [/tex]

Answer:

n = 81

Step-by-step explanation:

The left angle in the upper triangle and 44° are Alternate angles and congruent.

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

n is an exterior angle of the upper triangle, thus

n = 44 + 37 = 81

Answer:

area a=lxb

48=(x+10)x(x-3)

48=x2-3x+10x-30

0=x2+7x-30-48

0=x2+7x-78

hence it is proved

The requried, we have shown that x satisfies the equation x² + 7x - 78 = 0.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,
The area of the rectangle is given by the formula:

Area = length x width

Substituting the given expressions for length and width, we have:

Area = (x + 10)(x - 3)

We are also told that the area of the rectangle is 48 cm², so we can set up the equation:

(x + 10)(x - 3) = 48

Expanding the left side using the FOIL method:

x² - 3x + 10x - 30 = 48

Simplifying:

x² + 7x - 78 = 0

Therefore, we have shown that x satisfies the equation x² + 7x - 78 = 0.

Answer:

Step-by-step explanation:

A circle has a diameter of 3 meters. Which statement about the circumference and area is true?

A comparison of the area and circumference is not possible since the area cannot be determined.

The numerical value of the circumference and area are equal.

The numerical value of the circumference is greater than the numerical value of the area.

The numerical value of the circumference is less than the numerical value of the area.

Using the area and the circumference of the circle, it is found that the correct statement is given by:

The numerical value of the circumference is greater than the numerical value of the area.

The area of a circle of diameter d is given by:

[tex]A = \frac{\pi}{4}d^2[/tex]

The circumference of a circle of diameter d is given by:

[tex]C = \pi d[/tex]

In this problem, we have that d = 3, hence:

[tex]A = \frac{\pi}{4} \times 3^2 = \frac{9\pi}{4} = 2.25\pi[/tex]

[tex]C = \pi \times 3 = 3\pi[/tex]

Hence the correct option is given by:

The numerical value of the circumference is greater than the numerical value of the area.

Answer:

Step-by-step explanation:

Original equation:

7/2x - 3(5x - 1/2) = ?

Use distributive property for the parentheses

-3 · 5x = -15x

-3 · (-1/2) = 3/2 or 1.5

Plug these values into the equation

7/2x - 15x + 1.5 = ?

Combine like factors

-11.5x + 1.5 = a (a = answer)

The equation with fractions:

-11 1/2 + 1 1/2 = a

The change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.

Linear function is the function in which the highest power of the unknown variable is one. Linear functions used to model the real life problem in the mathematical expressions.

The linear function with dependent variable y and independent variable x can be written as,

[tex]y=mx +c[/tex]

Here, (m) is the slope of the function and (c) is the y intercept.

The slope can be found out as,

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The sound level is plotted on x-axis and frequency of people walking up (%) is plotted on y-axis. The slope of the line given the rate of change of y values with respect to x value.

In the graph given, the frequency of people walking up is 10 at 55 decibels and 55 at 95 decibels. The point, we get for this line are (55, 10) and (95, 55). Therefore the slope or the change of rate is,

[tex]\dfrac{dy}{dx}=\dfrac{55-10}{95-55}\\\dfrac{dy}{dx}=\dfrac{45}{40}\\\dfrac{dy}{dx}=\dfrac{9}{8}[/tex]

Hence, the change of the frequency of people waking up with respect to the sound level, 9% per 8 decibels.
