describe how to map line p onto line q

Answer:

153.86

Step-by-step explanation:

to get the area of the circle you take the radius to the power of 2 and then multiply with π
when the radius of circle S is half the radius of circle L and circle L has radius 14 inch, then the radius of S is 7.
area = radius² * π = 7² * π = 49 * π
π is approximately 3.14
so 49*3.14 = 153.86

As gradients multiplied we get [tex]\frac{-4}{3}[/tex] the line segments AB and BC are not perpendicular

How to find lines are perpendicular?

Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane. Vertical and horizontal lines, or the axes of the coordinate plane, are perpendicular to one another. Two parallel lines' slopes have negative reciprocal slopes.

To find whether the line segments are perpendicular we have to first find the gradient of AB and BC

Finding the gradient of AB

A(1,3) and B(2,1)

[tex]m_{AB}[/tex]=(1-3)/(2-1)

       = [tex]\frac{-2}{1}[/tex]

       =-2

Finding the gradient of BC

B(2,1) and C(5,3)

[tex]m_{BC}[/tex]=(3-1)/(5-2)

      =[tex]\frac{2}{3}[/tex]

When we multiply the two gradients if we get -1 then the two line segments are perpendicular.

[tex]m_{AB}X m_{BC} = -2X\frac{2}{3}[/tex]

                  = [tex]\frac{-4}{3}[/tex]

As the gradient is not equal to -1 the line segments AB and BC are not perpendicular

What is the place value strategy?

The place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, use your places values, such as tens and hundreds. It is possible to employ enlarged notation or compensation. Using regrouping techniques, you can make the problem easier by compensating for addition.

We must determine the values of each integer in order to calculate the value of the underlined digit (6) in the equation.

In 5,678.321, the first digit, 5, is 1,000 in the thousands of places.

The second digit, 6, is in the hundreds (100) place.

The angle with cosine value of 1/7​ is 81.79°

Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a right-angled triangle with its angles

Given that: the cosine value of the angle is 1/7​

Let the angle be θ. Then we can write that:

cos θ = 1/7

θ = cos⁻¹ (1/7)           (Take the inverse of cosine on both sides)

θ = 81.79°

Note: To get cos⁻¹ on your calculator, press the shift button followed by the cos button

The height of the goalpost is 16.45 m.

Given, Anand uses a mirror on the ground to measure the height of his school’s football goalpost.

He walks a distance of 14.75 meters from the goalpost, then places a mirror on flat on the ground, marked with an X at the center.

He then steps 1.3 meters to the other side of the mirror, until he can see the top of the goalpost clearly marked in the X.

His partner measures the distance from his eyes to the ground to be 1.45 meters.

we are asked to determine the height of the goalpost = ?

As per the rule of reflection in physics,

Angle of incidence = Angle of reflection

As we can see in the picture attached, both the angles (θ) are equal.

m∠ACB = m∠ECD = 90° - θ

m∠ABC = m∠ADC = 90°

Therefore, both the triangles ΔABC and ΔEDC will be similar.

And by the property of similar triangles, their corresponding sides will be proportional.

AB/ED = CB/CD

1.45/ED = 1.3/14.75

ED = 14.75×1.45/1.3

ED = 16.45 m

Hence the height of the goal post is 16.45 m

Los capitales depositados en las cuentas de 2 %, 3 % y 4 % son 630.000, 420.000 y 315.000, respectivamente.

En este problema tenemos el caso de una suma de dinero distribuida y depositada en tres cuentas con tres tasas de interes simple distintas. Existe una tasa de interés simple cuando el interés generado sobre el capital no es acumulativo en el tiempo. El modelo de interés simple es descrito por la siguiente fórmula:

C' = C · (1 + r / 100)

Donde:

A continuación, describimos la ganancia registrada en cada cuenta tal que produce la misma ganancia:

Cuenta al 2 %:

z = x · (2 / 100)

z = 0.02 · x

0.02 · x - z = 0

Cuenta al 3 %:

z = y · (3 / 100)

z = 0.03 · y

0.03 · y - z = 0

Cuenta al 4 %:

z = (1.365.000 - x - y) · (4 / 100)

z = 54600 - 0.04 · x - 0.04 · y

0.04 · x + 0.04 · y + z = 54600

La solución de este sistema de ecuaciones lineales se obtiene mediante métodos numéricos:

(x, y, z) = (630.000, 420.000, 12.600)

Finalmente, el capital depositado en la cuenta al 4 % es:

c = 1.365.000 - 630.000 - 420.000

c = 315.000

Se deposita capitales de 630.000, 420.000 y 315.000 en las cuentas de 2 %, 3 % y 4 %, respectivamente.

The graph of the inequality, y ≤ -2/5x - 4, is shown below

From the question, we are to graph the given linear inequalities.

The given linear inequalities is y ≤ -2/5x - 4.

To graph the linear inequality,

First, we will draw the line of the equation y = -2/5x - 4

To draw the line, we will use the x-intercept and y-intercept.

y-intercept

When x = 0

y = -2/5x - 4

y = -2/5(0) - 4

y = 0 - 4

y = -4

Thus, the coordinate of the y-intercept is (0, -4)

x-intercept

When y = 0

y = -2/5x - 4

0 = -2/5x - 4

4 = -2/5x

4 × 5 = -2x

20 = -2x

x = 20/-2

x = -10

Thus, the coordinate of the x-intercept is (-10, 0)

Now, using the coordinates of the x and y-intercepts, the line of the graph is shown.

Since the sign of the inequality is less than or equal to (≤), the line is a solid line and the solution is below the line.
