y/9 = 4 2/3

y/9 =(3*4 +2)/3 mixed number

y/9=14/3

multiply by 9

y = 14*9/3

y = 42

Choice D

z/12 = 6 3/4

z/12 = (6*4+3)/4 mixed number

z/12 = 27/4

multiply by 12

z = 27*12/4

z=81

Can anyone please find the domain of this function

mihalych1998 [28]

Answer: [-1/8, infinity) , {x | X greater than or equal to -1/8}

Step-by-step explanation:

Domain is what x can be. Thus, in the function f(x), we place limits such as x cannot make the square root a negative number because then it would not be a real number. Thus 8x+4-3 can be simplified to 8x+1. Setting this to 0, we get 8x+1=0 which solves out to x cannot equal -1/8. Thus, x can equal and be greater than -1/8.

If you know the sine value for a given angle, how can you quickly find the cosecant value for that same angle?

pogonyaev

Answer:

See below

Step-by-step explanation:

Remember the quotient identity $\csc\theta=\frac{1}{\sin\theta}$ , so you need to take the reciprocal of the sine value for the given angle in order to get the cosecant value for that same angle.

Help me with my math quiz from friday 4/1 <br> SHOW STEPS

Hie!! I will be solving the questions in the sequence of the attachments.

_______________________________________

4. As line SU and TV are intersecting each other at O.

A.T.Q, ∠UOV = (7x - 4)°

∠SOT = 87°

Then, ∠UOV = ∠SOT {Vertically Opposite Angles}

$\rightarrow\sf{7x - 4=87}$

$\rightarrow\sf{7x =87+4}$

$\rightarrow\sf{7x =91}$

$\rightarrow\sf{x =\frac{91}{7}}$

$\rightarrow\boxed{\bf{x =13}}$

_______________________________________

5. radius = 17ft

circumference of circle = 2πr

$\rightarrow\sf{circumference=2\times\frac{22}{7}\times17}$

$\rightarrow\boxed{\bf{circumference=106.8ft}}$

_______________________________________

3. ∠1 and ∠2 - add to 180 (linear pair)

∠1 and ∠3 - equal (Vertically Opposite Angles)

∠3 and ∠4 - add to 180 (linear pair)

∠2 and ∠4 - equal (Vertically Opposite Angles)

_______________________________________

2. 160° + (6x - 16)° = 180° (linear pair)

$\rightarrow\sf{6x - 16 = 180-160}$

$\rightarrow\sf{6x - 16 = 20}$

$\rightarrow\sf{6x = 20+16}$

$\rightarrow\sf{6x =36}$

$\rightarrow\sf{x =\frac{36}{6}}$

$\rightarrow\boxed{\bf{x =6}}$
