lawyer [7]

Answer:

$x^{\frac{1}{8} } y^{8}$

Step-by-step explanation:

Given :

$(x^\frac{1}{4} y^{16} )^{1/2}$

Now,

$(x^\frac{1}{4} y^{16} )^{1/2}\\x^{\frac{1}{8} } y^{8}$

Use two sets of coordinates to write an equation<br> to describe the relationship.

Irina-Kira [14]

Answer/Step-by-step explanation:

An equation that describes the relationship can be written as $y = mx$ .

Using the two sets of coordinates, (2, 140) and (4, 280), calculate the slope (m) as shown below:

$\frac{y_2 - y_1}{x_2 - x_1} = \frac{280 - 140}{4 - 2} = \frac{140}{2} = 70$

Substitute m = 70 into $y = mx$

The equation would be:

$y = 70x$

This equation can be interpreted as follows:

The heart's resting rate is 70 beats each minute.
