Answer:

C.

Step-by-step explanation:

Domain is only affected if certain values can make the result something that either doesn't make sense or is an error. In your situation, it wants you to find the domain of f/g, which is a fraction. The only rule we have for fractions regarding domain is that we simply can't divide by zero, to find the domain for any fraction with variables in the denominator, what I do is take the denominator, set it equal to 0, and solve for x.

So, if we're taking f/g, we have:

\frac{3x^2 + x^4 + 2}{4x - 3}

4x - 3 makes up our denominator, the bottom part of the fraction. So

4x - 3 = 0

4x = 3

x = 3/4

So the denominator is equal to zero when x is equal to 3/4. This would produce an error in any calculator because you can't divide by zero. The domain here is all real numbers except for 3/4.

(For future problems, the only thing to look out for is if your numerator, the top part of the fraction, factors into something that cancels with the bottom. In that case, it wouldn't affect domain because you aren't actually dividing by anything. For example:

\frac{x^2 - 4}{x-2}

If we factor the top, we see that x^2 - 4 = (x - 2)(x + 2). In this case, we have (x - 2) in both the top and bottom of the fraction, so it cancels out, and from there nothing else is restricting our domain. It would be all real numbers in a case like that.)

A spinner is numbered from 1 through 12 with each number equally likely to occur.
katovenus [111]

Answer: EX:There are 10 numbers from 1 - 10

first we get the numbers less than 2 are (1)

secondly get the numbers greater than 7 are (8,9,10)

total = 4 numbers

The favorable probability is 4 / 10=2 / 5

hope it helps

Helpp!!Angles, degrees and, radians​
MAXImum [283]

Answer:

  1. co-terminal
  2. reference
  3. 90°, 105°
  4. 2π, 7π/4

Step-by-step explanation:

For an explanation of vocabulary questions, consult a dictionary or vocabulary list

1) angles ending in the same place are "co-terminal."

__

2) The acute angle between the terminal ray and the x-axis is the "reference angle."

__

3) Multiply radians by 180°/π to convert to degrees.

  a) π/2 × 180°/π = 180°/2 = 90°

  b) 7π/12 × 180°/π = (7/12)(180°) = 105°

__

4) To convert from degrees to radians, multiply by π/180°.

  a) 360° × π/180° = 2π radians

  b) 315° × π/180° = 7π/4 radians

The sum of two numbers is 43 . The smaller number is 19 less than the larger number. What are the numbers?
Setler [38]
Let the smaller number be x and the larger number be y.
We can calculate this by using simultaneous equation, aka listing 2 equations out.
From given,
X + y = 43
Let this be equation no. 1
X + 19 = y
Let this number be equation 2.
We can do simultaneous equations either by substitute method or elimination. In this case I'm using substitute.
We can already obtain the value of y (in terms of x) in euqation no. 2, so all we gonna do is to put y into equation 1.
X + x + 19 = 43
Solve this by algebra.
2x = 43 - 19
X = 12
Now we know the exact value of x
Now substitute x = 12 into equation no. 2
12 + 19 = y
Y = 31
So the answer is 12 and 31
