Answer:

θ = 81.89°

Step-by-step explanation:

Si tenemos un círculo de radio R, el perímetro de este círculo estará dado por:

P = 2*pi*R

donde pi = 3.14

Ahora, si en lugar de el círculo completo solo queremos la longitud de un dado arco, definido por un ángulo θ, el largo de ese arco estará dado por:

L = (θ/360°)*2*pi*R

Notar que cuando θ = 360° (es decir, el ángulo del círculo completo) el largo del arco será igual que el perímetro, lo cual deberíamos esperar.

Ahora sabemos que:

El arco tiene 50m de longitud.

El radio del círculo es 35m

queremos encontrar el valor de θ

Reemplazando esos valores en la ecuación de arriba obtenemos:

50m = (θ/360°)*2*3.14*35m

Ahora solo debemos resolver esto para θ

50m = (θ/360°)*219.8m

(50m/219.8m) = (θ/360°)

(50m/219.8m)*360° = θ = 81.89°

Answer:

5/36

Step-by-step explanation:

There are 12 tiles

P( blue) = blue /total = 5/12

We put the first tile back so there are still 12 tiles in the bag

P(yellow) = yellow/total = 4/12 = 1/3

P( blue, yellow) = 5/12 * 1/3 = 5/36

Answer:

A. cos m L B = 2√5 /5

Step-by-step explanation:

cos m L B = AB / BC = 6/ 3√5

= 6√5 /15

= 2√5 /5

Let the original price = x

An increase of 10 % = 18.15

Multiply x by (1 + percent increase) which is 1.1x = 18.15

Now to find x divide both sides by 1.1:

X = 16.50

The original price was 16.50

Answer:

£16.50

Step-by-step explanation:

Let cost price be x

Now, create a formula:

x + 10x / 100 = 18.15

'or'

110x / 100 = 18.15

'or'

x = (18.15*100) / 110

x = 16.5

Answer:

[tex]A = 2.25ft[/tex]

Step-by-step explanation:

Given

[tex]High = 5.5ft[/tex]

[tex]Low = 1ft[/tex]

Required

The amplitude (A)

This is calculated as:

[tex]A = \frac{1}{2}(High - Low)[/tex]

So, we have:

[tex]A = \frac{1}{2}(5.5ft - 1ft)[/tex]

[tex]A = \frac{1}{2} * 4.5ft[/tex]

[tex]A = 2.25ft[/tex]

Absolute value is the distance that a number is away from zero. Keep in mind that the absolute value is always positive.

However since the negative sign is on the outside of the function , you leave it on the final answer. Therefore the answer is -4

The real roots of a function are located where the function passes through the x-axis. In this case, the function passes through x=-1 and x=3, making them the real roots of the function.

Answer:

A'E' = AE

Step-by-step explanation:

Transformation is the movement of a point from its initial position to a new position. Types of transformation are rotation, reflection, translation and dilation. If an object is transformed then all its points are also transformed.

Rigid transformations are transformations that preserves the shape an size of an object (i.e. the side length and angles). Examples of rigid transformations are rotation, translation and reflection.

Since rotation is a rigid transformation, the side lengths and angles of polygon A'B'C'D' would be the same as that of polygon ABCD. Therefore:

A'E' = AE

Answer:

Step-by-step explanation:

2a^2b + 6ab^2

take common

2 can be taken common because there is 2in first term and there is 6 in second term and 2 can exactly divide 6 .there is a*a in first term and only a in second term so u can take a as common.There is only b in first term and b*b in second term so take u can take b as common.

total we can take

2ab as common.So,

2ab(a+3b)

therefore 2ab(a+3b) is the required answer.

The required factorization is  2ab(a+3b).

Factorization in mathematics is the process of dividing a large number into smaller ones that, when multiplied together, give you the original number. Factorization is the process of dividing a number into its components or divisors.

Expanding brackets in reverse is a procedure known as factorizing.

Fully factorizing an equation entails putting it in brackets by eliminating the components with the highest common denominator.

Finding the highest common factor between all the terms in the phrase is the easiest technique to factorize.

We have, 2a²b + 6ab²

Here,

we have the highest common factor 2ab,

So, 2ab (a + 3b)

Therefore, 2ab(a+3b) is the required factorization.

Answer:1565

Answer:

Step-by-step explanation:

An explicit arithmetic formula in standard form is

[tex]A_n=a_1+d(n-1)[/tex] where n is the position of a number in thesequence, a1 is the first number in the given sequence, and d is the common difference. The common diff here is -5 since we have to subtract 5 from each term to get to the next one in the sequence. The first number is -12. So

a1 = -12

d = -5 and the explicit formula is

[tex]A_n=-12-5(n-1)[/tex] and you could simplify it a bit to

[tex]A_n=-12-5n+5[/tex] and finally to

[tex]A_n=-5n-7[/tex] which is a linear representation. Arithmetic sequences can all be simplified down to represent lines.
