Change you’ll receive is = 0.09
you can only buy 11 because if you divide 20/11 it will give you 1.81 and if you multiply 11x 1.81 it will give you 19.91 which is close to $20 & that’s the most you can buy .

Answer:

Step by step explanation:

The equation of the tangent to the curve at the point P(2, -10) is:
y = 8x - 26



We need to find the coordinates of point Q where the slope of the tangent to the curve f(x) must also be 8.

Now we have a quadratic:

which simplifies to:

which factorizes to:(x + 4)(x - 2) = 0
Therefore x = -4, 2.
f(-4) = 48
Therefore the coordinates of Q are (-4, 48).
