Answer:

Statement 4 is incorrect.

Step-by-step explanation:

#4 is incorrect. This statement is assuming that both 3x+5 and 4x are equal, but the correct way to use them and achieve 180 (definition of supplementary) degrees is by writing it as: 3x+5 + 4x = 180. (I spaced the 3x+5 and 4x to make it clear that these are two angles added together.) With this equation, you will be able to find the x and the substitute it back in to complete the equation.

Are integers that are not whole numbers.
Allushta [10]
Integers can be whole numbers or they can be whole numbers with a negative sign in front of them. Individuals often refer to integers as the positive and negative numbers. Integers are -4, -3, -2, -1, 0, 1, 2, 3, 4 and so on.

Match the function with its graph.
Oxana [17]

Answer:

The answer is 1D , 2A , 3C , 4B ⇒ answer (c)

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

* Lets explain each function

∵ y = tan(x)

∵ y = -tan(x - π/2)

# (x - π/2) means the graph translated horizontally to

  the right π/2 units

# -tan(x - π/2) means the graph reflected across the x-axis

∴ The graph is (D)

* 1) y = -tan(x - π/2) ⇒ (D)

∵ y = tan(x + π/2)

# (x + π/2) means the graph translated horizontally to

  the left π/2 units

∴ The graph is (A)

* 2) y = -tan(x - π/2) ⇒ (A)

∵ y = -cot(x - π/2)

# (x - π/2) means the graph translated horizontally to

  the right π/2 units

# -cot(x - π/2) means the graph reflected across the x-axis

∴ The graph is (C)

* 3) y = -cot(x - π/2) ⇒ (C)

∵ y = cot(x + π/2)

# (x + π/2) means the graph translated horizontally to

  the left π/2 units

∴ The graph is (B)

* 4) y = -tan(x - π/2) ⇒ (B)

∴ The answer is 1D , 2A , 3C , 4B answer (c)

Convert the following decimal values into binary (a) 141 (b) 207 (c) 144
sergejj [24]

Answer:

a)(141)_{10}=(10001101)_2

b)(207)_{10}=(11001111)_2

c) (144)_{10}=(10010000)_2                    

Step-by-step explanation:

We need to convert decimal value  in binary value

So Follow the below steps

Keep on dividing the decimal values by 2 until the denominator becomes 0 or 1.

a)

    Decimal value                  Quotient         Remainder

        141                                     70                       1            

        70                                     35                       0

        35                                      17                        1

        17                                        8                         1

        8                                          4                        0

        4                                          2                        0

        2                                           1                        0

        1                                            0                        1

Now write remainder  from bottom to up 10001101.

(141)_{10}=(10001101)_2

10 base is called  decimal value and base 2 is called binary value.

b)

  Decimal value                  Quotient         Remainder

        207                                     103                    1            

        103                                    51                        1

        51                                      25                       1

        25                                      12                       1

        12                                        6                       0

        6                                          3                      0

        3                                          1                       1

        1                                           0                      1

Now write remainder  from bottom to up 11001111.

 (207)_{10}=(11001111)_2    

c)

 Decimal value                  Quotient         Remainder

        144                                     72                   0            

        72                                     36                     0

        36                                      18                     0

        18                                       9                      0

        9                                        4                       1

        4                                        2                      0

        2                                         1                      0

        1                                          0                     1                                                                      

Now write remainder  from bottom to up 10010000.

 (144)_{10}=(10010000)_2
