✿ $\underline{\textbf{\textsf{ \purple{Solution}:- }}}$

$\sf{\\}$

Given that,

$\quad\quad\bullet \sf{ \alpha = (1, -7) = (x_1,y_1)}$

$\quad\quad\bullet \sf{ \beta = (4, -5) = (x_2, y_2)}$

Then the distance between $\alpha$ and $\beta$ is given by

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

$\sf{\\}$

So coming back to the question, using the formula, here, the distance between $\alpha$ and $\beta$ will be,

$\sf{\sqrt{(4 - 1)^2 + \Big(-5 - (-7)\Big)^2}}$

$\longrightarrow \sf{\sqrt{ 3^2 + 2^2 }}$

$\longrightarrow \sf{\sqrt{9 + 4}}$

$\longrightarrow \sf{\sqrt{13}}$

$\approx \sf{3.6055}$

On rounding it to nearest tenth,

$\leadsto \underline{\boxed{\mathfrak{\pink{3.6}}}}$

Jamal needs to save $254.17 each month to cover his expenses.

Step-by-step explanation:

We know that there are 12 months in a year, and Jamal already has $1,000 towards college. Jamal still needs to save $3,050 more dollars because: 4,050 - 1,000 = 3,050. Next, we take how much he has yet to pay ($3,050) divided by how many months in 1 year (12), and that gives us 254.17 per month.
