$one \ half \to \frac{1}{2} \\\\ three \ tenths \to \frac{3}{10} \\\\ \frac{1}{2}^{(5}+\frac{3}{10}= \\\\=\frac{5+3}{10}= \\\\ =\frac{8}{10}\to\boxed{\boxed{\frac{4}{5}}}$

$\boxed{ \frac{1}{2}+ \frac{3}{10} = \frac{1\times5}{2\times5} + \frac{3}{10} = \frac{5}{10}+ \frac{3}{10} = \frac{8}{10}=0,8 }$

Find the distance that the points is given on the graph ?

EleoNora [17]

From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:

$\large \boxed{ \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } }$

Substitute these points in the formula.

$\large{ \sqrt{ {(2 - 4)}^{2} + {( - 1 - 0)}^{2} } } \\ \large{ \sqrt{ {( - 2)}^{2} + {( - 1)}^{2} } } \\ \large{ \sqrt{4 + 1} \longrightarrow \sqrt{5} }$
