Which set of ordered pairs could be generated by an exponential function?

devlian [24]

<u>ANSWER</u>

(0, 1), (1, 3), (2, 9), (3, 27)

<u>EXPLANATION</u>

The first and third options are completely out because the y-value of an exponential function is never zero.

For the second option the y-values has no geometric pattern or common ratio.

For the last option, we can observe the following pattern

$1 = {3}^{0}$

${3}^{1} = 3$

${3}^{2} = 9$

${3}^{3} = 27$

${3}^{x} = y$

The correct choice is the last option

If the area of a square is 36 square unit what si the length of a side of the square

kodGreya [7K]

Answer:

The length of the square is 6 units.

Step-by-step explanation:

Given that all sides of the square are the same and the area of square formula is A = length×breadth. So let's make x as the sides :

$area = length \times breadth$

$let \: area = 36 \\ let \: sides \: = x$

$36 = x \times x$

${x}^{2} = 36$

$x = ± \sqrt{36}$

$x = 6 \: units$

$x = - 6 \: (rejected)$
