You should try starting a conversation with him if you're in the same class/have a class together you can ask how he's liking the class. Don't straight up ask to be his friend that might make him confused. Work on it a little each day maybe even try to compliment him a few times. I hope this helpsss
<u>Chord of Contact:-</u>
- The chord joining the points of contact of two tangents drawn from an external point to a parabola is known as the chord of contact of tangents drawn from external point.
Equation of the normal chord at any point (at², 2at) of the parabola y² = 4ax is
y + tx = 2at + at³ ....(i)
Look at the attached figure
But if M (x₁, y₁) be it's middle point its equation must be also,
T = S₁
:⟹ yy₁ - 2a (x + x₁) = y₁² - 4ax₁
:⟹ yy₁ - 2ax = y₁² - 2ax₁ .....(ii)
Therefore, from eqs. (i) and (ii) are identical, comparing, them

Answer:
6/28 or 0.214
Step-by-step explanation:
6/7÷4=6/7÷4/1
6/7÷4/1=6/7×1/4
6/7×1/4=6/28
Not sure if you're allowed to leave it in a fraction or not, so as a decimal, it's 0.214 to 3 s.f.
Hope this helps :-)
