Calculate the slope:
m = y2-y1 / x2-x1
m = 4-3 / 4-2
m = 1/2

Now, y-y1 = m(x- x1)
y - 3 = 1/2(x - 2)
y - 3 = 1/2x - 1
y = 1/2x + 2

In short, Your Answer would be: Option A

Hope this helps!

Using the Law of Cosines, in triangle DEF, if e=18yd, d=10yd, f=22yd, find measurement of angle D
Ivahew [28]
Check the picture below.

\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}
\\\\\\
\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}=cos(C)\implies cos^{-1}\left(\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}\right)=\measuredangle C\\\\
-------------------------------\\\\
\begin{cases}
d=10\\
e=18\\
f=22
\end{cases}\implies cos^{-1}\left(\cfrac{{{ 18}}^2+{{ 22}}^2-10^2}{2(18)(22)}\right)=\measuredangle D

\bf \implies cos^{-1}\left(0.893\overline{93}\right)=\measuredangle D\implies 26.63^o\approx \measuredangle D

The formula of the compound interest is V = V₀(1+r%)ⁿ, where V₀ is the initial amount invested, r= interest in%, n = the period or number of years
and V the new amount of his investment:
In your given formula 1250(1.03)^t which is similar to V= 1250(1+3%)^t
We notice that 1250 occupies the place of the initial investment, so Rashid
invested 1250
