The model to use here is y = k/x.
If g =18 when r = 4, then 18 = k/4. Solving for k, k = 72.
Then g = 72/r. If r = 6, g = 72/6 = 12 (answer)
Answer:
Step-by-step explanation:
In addition of polynomials, you only have to add the like terms.
Remember the multiplication of signs:
Then, given the polynomial and the polynomial , you can find the sum of them by adding the like terms.
Observe the procedure below:
Therefore, the sum is:
Answer:

Answer:
A) 3/16
B) 1 - 3/16 = 13/16
C) 7/16 + 8/16 - 3/16 = 12/16 = 3/4
<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
