Answer 1

To find the distance between the points \((1, 0)\) and \((9, 15)\), we can use the distance formula:

\[
d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
\]

where \((x_1, y_1) = (1, 0)\) and \((x_2, y_2) = (9, 15)\).

Substituting the values:

\[
d = \sqrt{(9 - 1)^2 + (15 - 0)^2}
\]

Calculating the differences:

\[
d = \sqrt{(8)^2 + (15)^2}
\]

Now, squaring the differences:

\[
d = \sqrt{64 + 225}
\]

Adding the squared values:

\[
d = \sqrt{289}
\]

Finally, taking the square root:

\[
d = 17
\]

Thus, the distance between the points \((1, 0)\) and \((9, 15)\) is \(17\).
