Given that tan π/6 = 1/√3 and tan 3π/4 = -1. Express tan 7π/12 in the form of r + k√q, where k,r and q are integers. Hence, show

that tan 7π/6 = √q/3

Brooke has to set up 70 chairs in equal rows for the class talent show. But, there is not room for more then 20 rows. What are t

grin007 [14]

Answer:

The answer is 2, 5, 7, 10, and 14.

Step-by-step explanation:

Let x be the number of rows. There is not room for more than 20 rows:

x ≤ 20

Since all rows must be equal, when we divide 70 by x, we must get a whole number. So, we must find all divisors of 70 smaller or equal to 20 and they are: 2, 5, 7, 10, and 14.

So, the possibilities are:

2 rows with 35 chairs in each row

5 rows with 14 chairs in each row

7 rows with 10 chairs in each row

10 rows with 7 chairs in each row

14 rows with 5 chairs in each row

Hope this helps!!

-12-x>-12+4x<br> put the steps too pls thanks

andrey2020 [161]

Answer:

x < 0

Step-by-step explanation:

Firstly put the values with variable x to one side,

; -12 - x > -12 + 4x

; -12 + 12 > 4x + x

; 0 > 5x

then divide both sides by 5,

; (0 ÷ 5) > (5x ÷ 5)

; 0 > x

; Hence the solution to the inequality above,

; x < 0...always remember to reverse the sign when you change the side to which you put the variable of x,

Therefore...( x < 0 )

Which of the following represents the zeros of f(x) = 6x3 + 25x2 − 24x + 5?

cestrela7 [59]

F(-5) = 6(-5)^3 + 24(-5)^2 - 24(-5) + 5 = 0
so x = -5 is one zero.

Answer:

<em>x = y = 64° , z = 20°</em>

Step-by-step explanation:

<em>x = y</em> = $\frac{180-52}{2}$ <em>= 64 </em>°

m∠ADC = 52° + x

m∠ADC = 52° + 64° = 116°

<em>z</em> = 180° - 116° - 44° <em>= 20</em> °
