The domain is the set of all the x-values/inputs used by the function.  

The range is the set of all y-values/outputs used by the function.

For #1:

The domain is { 1, 0, -1, 4 } because those are the x-values.

The range is { 3, 5, 7, -6 } because those are the x-values.

I'll let you try #2.  if you write back with your answer, I'll reply to let you know if you did it correctly.

Answer:

A. total hourly pay $380.00 &

B. total pay for the week $493.25

Step-by-step explanation:

38 hours x $10 per hour = 380.00

755 unit products x .15 = 113.25

380 hourly pay + 113.25 unit pay = 493.25

Step-by-step explanation:

the aswer is...false

It is false that 5 . 26 − □ = 1 . 38 The value 3.12 makes the equation. To check if the value 3.12 makes the equation true or false, we can substitute it into the equation and see if both sides are equal.

Given equation:

5.26 − □ = 1.38

Substitute □ with 3.12:

5.26 − 3.12 = 1.38

Now, calculate the left-hand side:

5.26 - 3.12 = 2.14

The equation becomes:

2.14 = 1.38

Since 2.14 is not equal to 1.38, the equation is false when □ is replaced with 3.12.

Therefore, the value 3.12 does not make the equation true.

An angle that is adjacent and congruent to m ∠FTK is, m ∠HTK. So option 1 is true.

Used the concept of angle that states,

An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

T lies on both FH and GJ.

Now by the given figure;

m ∠FTK = 90 degrees

Hence, an angle that is adjacent and congruent to m ∠FTK is,

Answer:

All real numbers

Step-by-step explanation:

4(x+1) = 4x+4

Distribute

4x+4 = 4x+4

Subtract 4x from each side

4x+4-4x = 4x+4-4x

4=4

This is always true so there are infinite solutions

Solution:

Let's find the required solution,

→ 4(x + 1) = 4x + 4

→ 4x + 4 = 4x + 4

→ (4x - 4x) + 4 = 4

→ 4 = 4

→ LHS = RHS

The answer is all real numbers.

Step-by-step explanation:

No, the results are not necessarily representative of the school as a whole.

A random survey is a research technique that is used to gather information from a sample of people or things in a population. The results of a random survey are more likely to be representative of the population as a whole since every member of the population has an equal chance of being chosen to take part in the research.

Given:

Ivy randomly surveys students in her school to learn more about mobile phone password use.

Of 25 respondents, 14 use a password.

If the survey was conducted on a volunteer basis, it is possible that the respondents who chose to participate may have different characteristics or behaviors than those who did not participate.

This could lead to a biased sample that does not accurately represent the entire school population.

Additionally, even if the sample is representative of the school population, a sample size of 25 is relatively small, which can increase the margin of error and make it more difficult to draw accurate conclusions.

Therefore, it is important to consider the limitations of the survey method and sample size when interpreting the results.

7x³ + 7x² + 2x - 8

Step-by-step explanation:

Let the unknown polynomial be a

a + -3x³ + 2x - 5 = 4x³ + 7x² - 3

a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)

a = 4x³ + 7x² - 3 + 3x³ + 2x - 5

a = 7x³ + 7x² + 2x - 8

Answer:

  x ≠ 3

Step-by-step explanation:

In any case, the domain is restricted to values of the variable for which the function is defined. The value 1/0 is not defined, so the variable cannot allow the denominator to be zero. The denominator x-3 will be zero for x=3, so that value of the variable cannot be in the domain.

The domain is all real numbers except x=3.

Additional comments

It is useful to become familiar with the domains of different functions. As we saw above, the reciprocal of 0 is undefined. The square root of a negative number is undefined. The log of a non-positive number is undefined. Trig functions are defined everywhere, but their inverse functions are not. Polynomial functions are defined everywhere, but ratios of polynomials have the same restriction on denominators that we see above.

You need to find the HCF of 36 and 90.

Prime factors of each:

HCF includes all prime factors of both numbers:

To find the least number,

Which is exactly divisible by 36 and 90. We have to find the HCF of 36 and 90.

→ 36 = 2 × 2 × 3 × 3

→ 90 = 2 × 3 × 3 × 5

Then the required HCF will be,

→ 2 × 2 × 3 × 3 × 5

→ 180 (HCF)

Thus, 180 is the least number which is exactly divisible by 36 and 90.
