Answer:

1/25

Step-by-step explanation:

f(x)=5^x

Let x = -2

f(-2)=5^-2

Find the distance between the two points rounding to the nearest tenth (if necessary).

Genrish500 [490]

Answer:

13 units

Step-by-step explanation:

(-1,5) and (4, -7)

To find the distance of two points, we use the distance formula:

$d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }$

Let's plug in what we know.

$d = \sqrt{(4 - (-1))^2 + (-7 - 5)^2 }$

Evaluate the double negative.

$d = \sqrt{(4 +1))^2 + (-7 - 5)^2 }$

Evaluate the parentheses.

$d = \sqrt{(5)^2 + (-12)^2 }$

Evaluate the exponents.

$d = \sqrt{(25) + (144) }$

Add.

$d = \sqrt{(169) }$

Evaluate the square root.

$d = 13$
