The area of a square is l^2=A because the length and width are the same length. So this would be 21^2 or 21*21. Your answer will be 441in^2.

Given f(x) and g(x) = f(k⋅x), use the graph to determine the value of k.
yan [13]

Answer:

The value of k is 3.

Step-by-step explanation:

The function f(x) passes through the points (0,4) and (-6,-2)

So the equation of the function is \frac{y-4}{4-(-2)} = \frac{x-0}{0-(-6)}

⇒ y = x + 4 ....... (1)

Again the function g(x) passes through the points (0,4) and (-2,-2).

Therefore, the equation of g(x) will be  \frac{y-4}{4-(-2)} =\frac{x-0}{0-(-2)}

⇒ y = 3x + 4

Therefore, g(x) = 3x + 4 = f(3x) {from equation (1).

So, the value of k is 3. (Answer)

sattari [20]

Domain: -4, -1, 6, 8, 9

Range: -2, 0, 4, 5

Domain can easily be found by looking through the set's x-coordinates.

Range can be found on the y-coordinates.

Repeating numbers just needs one number to be listed (Ex. the range has two 4's but there is only one 4 listed).

Write them in order.

faltersainse [42]

Answer:

21.6 hours

Step-by-step explanation:

Hypothesis testing allows to identify a event test. The correct order of the steps of a hypothesis test is given following  

1. Determine the null and alternative hypothesis.

2. Select a sample and compute the z - score for the sample mean.

3. Determine the probability at which you will conclude that the sample outcome is very unlikely.

4. Make a decision about the unknown population.

These steps are performed in the given sequence to test a hypothesis.

The principal tests the hypothesis with a mean of 21.6 hours for the determination of average amount of time spent watching television.
