Clara is growing her hair out and wants it to be no longer than 15 cm but more than 11 cm. Her hair is 7 cm right now and grows

at a rate of 0.25 cm per week. The compound inequality
11 < 7 + 0.25t ≤ 15 models the scenario.

Assuming you are asking how many weeks, than the answer would be 17-32, because at 16 weeks the growth would be 4 cm, totaling at 11, but you need more than 11cm, and at 32 weeks it's at 15 cm.

Consider this product. x^2-4x-21/3x^3+6x x^2+8x/x^2+11x+24 Which values are excluded values for the product?
lesya [120]

Using the domain, it is found that x = -8 is excluded for the product.

The domain of a function is the <u>set that contains all possible input values</u>.

  • In a fraction, the <u>denominator cannot be 0</u>.

In this problem, there are two fractions, and the points outside the domain, that is, the roots of the denominators, are excluded.

For the first fraction, they are:

3x^2 + 6x = 0

3x(x + 2) = 0

3x = 0 \rightarrow x = 0

x + 2 = 0 \rightarrow x = -2

Hence, x = -2(not an option) is excluded.

  • x = 0 can be factored with the numerator of the second fraction, so not excluded.

For the second fraction, the roots of the denominator are:

x^2 + 11x + 24 = 0

Which is a quadratic equation with <u>coefficients</u> a = 1, b = 11, c = 24, hence:

\Delta = b^2 - 4ac = 11^2 - 4(1)(24) = 121 - 96 = 25

x_1 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{-11 - 5}{2} = -8

x_2 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-11 + 5}{2} = -3

x = -3 can be factored with the numerator of the first fraction, so only x = -8 is excluded.
