G(x) = 54<br> What is the domain for this function

Fudgin [204]

Answer:

x is all real numbers.

Step-by-step explanation:

Since there is only 1 value of y, it is a straight line. Since domain measures the range of x values, it can be any real number as the line goes from negative infinity to infinity.

Can someone answer this for my homework

kenny6666 [7]

we are given

The angle is at right angled

It means that it's angle will be 90 degree

Since, these angles are part of right angle

so, their sum must be 90 degree

so, we get

$4a+5+3a-6=90$

now, we can solve for a

$4a+3a-1=90$

$7a=91$

divide both sides by 7

and we get

$a=13$ .............Answer

Translate (in terms of x) then solve the algebraic equation. When the sum of a number and 2 is subtracted from 13 the result is

Diano4ka-milaya [45]

13 - (x+2) = 8
subtract 13 from both sides
-(x+2) = -5
divide by -1 to get rid of negative
(x+2) = 5
subtract 2 from both sides
x=3

Will mark Brainlest help me to multiply it step by step without using calculator

Fynjy0 [20]

Answer:

$\displaystyle\theta = {30}^{ \circ}$

Step-by-step explanation:

we would like to solve the following equation:

$\displaystyle\sin( \theta) = \frac{5}{10}$

notice that, the fraction can be reduced therefore reduce fraction:

$\displaystyle\sin( \theta) = \frac{ \cancel{5 \: }}{ \cancel{1 0} _{2} }$

$\displaystyle\sin( \theta) = \frac{1}{2}$

by trigonometric value table we obtain:

$\displaystyle\sin( \theta) = \sin( {30}^{ \circ} )$

get rid of sin:

$\displaystyle\theta = {30}^{ \circ}$

and we are done!
