To ease the understanding, let's write it in degrees and not in Radian:

Formula of conversion: Degree°/180 = Radian/π

Convert 7π/4 in degrees: = (7x180)/4 = 315°

This angle is in the IV th Quadrant of the UNIT circle. So you can write 315° or - 45° .

sin(7π/4) = sin(315°) = sin( - 45°) = - sin(45°) = - (√2)/2

Answer:

The answer to your question is the letter A. 20 ft²

Step-by-step explanation:

Data

length of a side = 10 ft

length of the diameter = 10 ft

length of the radius = 5 ft

Process

1.- Calculate the area of the square

Area of the square = side x side

                                = 10 x 10

                                = 100 ft²

2.- Calculate the area of the circle

Area = πr²

Area of the circle = (3.14)(5)²

Area of the circle = 78.5 ft²

3.- Calculate the remaining area

Remaining area = 100 - 78.5

Remaining area = 21.5 ft²   ≈ 20 ft²

Lapatulllka [165]

Answer:

The number of ways this can be done is 1,260 ways

Step-by-step explanation:

In this question, we are asked to calculate the number of ways in which the letters of the word balloon can be arranged.

To do this, we take into consideration those letters that are repeated and the number of times repeated. The letters are l and o and are repeated two times each.

The number of ways = 7!/2!2! = 5040/4 = 1,260 ways

SOLVE FOR M. please :)
STatiana [176]

Answer:

m =  - 28

Step-by-step explanation:

\frac{ - 3}{7} m = 12

\frac{ - 7}{3} ( \frac{ - 3}{7})m =  \frac{ - 7}{3}  \times 12

\frac{ - 1}{3} ( - 3)m =  \frac{ - 7}{3}  \times 12

- 1( - 1)m =  \frac{ - 7}{3}  \times 12

1 \times m =  \frac{ - 7}{3}  \times 12

m =  \frac{ - 7}{3}  \times 12

m =  \frac{ - 7}{3}  \times 12

m =  \frac{ - 7}{3} (3 \times 4)

m =  - 28

Watch help video Given mn, find the value of x. (6x-3)⁰ (2x+13)°​
Ilia_Sergeevich [38]

Answer:

x = 4

Step-by-step explanation:

(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.

(6x - 3)° = (2x + 13)°

6x - 2x = 13 + 3

4x = 16

x = 4

Substitute x for the angles.

(6x - 3)° = ?

(6*4 - 3)° = ?

(24 - 3)° = 21°

(2x + 13)° = ?

(2*4 + 13)° = ?

(8 + 13)° = 21°
