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).

Answer:
The probability that between 64 and 90 of them read the ingredients listed on a product's label is 0.82.
Step-by-step explanation:
We know the proportion of the population, that is π=0.28.
The standard deviation for this sampling distribution is
The value 64 represents a proportion of p=64/256=0.25, and the value 90 represents p=90/256=0.35.
With these values, we can calculate the z-values.
The probability that between 64 and 90 read the ingredients is:
The probability that between 64 and 90 of them read the ingredients listed on a product's label is 0.82.
