$(\frac{y_{2} - y_{1}}{y_{1}}) \cdot 100 \% = (\frac{30-32.5}{32.5}) \cdot 100 \% = -7.6923076923076923076923076923077 \approx -7.7 \%.$

Answer:

The range in the average rate of change in temperature of the substance is from a low temperature of $-22^{\circ}$ to a high of $16^{\circ}$ .

Step-by-step explanation:

In the sinusoidal function $y=a\sin(b(x-c))+d$ , $|a|$ represents the amplitude and $y=d$ represents the equation of the midline.

By definition sinusoidal functions ebb and flow with respect to this midline. Therefore, the minimums must occur at $y=d-|a|$ and the maximums must occur at $y=d+|a|$ .

Thus, the minimum, or low, occurs at $y=-3-|-19|=-3-19=\boxed{-22}$ and the maximum, or high, occurs at $y=-3+|-19|=-3+19=\boxed{16}$ .

Find a cubic function with the given zeros. Square root of seven. , - Square root of seven. , -4

yan [13]

Answer:

$y= x^{3} +4x^{2}-7x-28$

Step-by-step explanation:

We have to find a cubic function of x whose zeros are at x = √7, x = -√7 and at x = -4.

Therefore, the factors of the function will be (x - √7), (x + √7), and (x + 4)

Hence, the equation will be y = (x - √7) (x + √7) (x + 4)

⇒ $y = (x^{2} -7)(x +4)$

⇒ $y= x^{3} +4x^{2}-7x-28$ (Answer)
