The population of California was 29.76 million in 1990 and 33.87 million in 2000. Use the model found in part a (f(x) =29.76(1.0

NeTakaya

Answer:

The average rate of change from 1990 to 1991 is $0.387 \:\frac{million}{years}$

The average rate of change from 2000 to 2001 is $0.440 \:\frac{million}{years}$

Step-by-step explanation:

The average rate of change of function f(x) over the interval $a\leq x\leq b$ is given by

$\frac{f(b)-f(a)}{b-a}$

It is a measure of how much the function changed per unit, on average, over that interval.

From the information given:

The function that models the population t years after 1990 is $f(t) =29.76(1.013)^t$
The year 1990 is t = 0 and the year 2000 is t = 10.

1. The average rate of change from 1990 to 1991 is:

The interval is $0\leq x\leq 1$

$\frac{29.76(1.013)^1-29.76(1.013)^0}{1-0}\\\\\frac{1.013^1\cdot \:29.76-1\cdot \:29.76}{1-0}\\\\\frac{0.38688}{1-0}\\\\0.387 \:\frac{million}{years}$

2. The average rate of change from 2000 to 2001 is

The interval is $10\leq x\leq 11$

$\frac{29.76(1.013)^{11}-29.76(1.013)^{10}}{11-10}\\\\\frac{0.44022}{11-10}\\\\0.440 \:\frac{million}{years}$

An oblique square prism is shown. Which expression represents the volume of the prism?

Furkat [3]

Answer:

C. $x^2*(x-2)\text{ Cubic units}$

Step-by-step explanation:

We have been given a diagram of an oblique prism and we are asked to choose the expression that represents the volume of the prism.

Since we know that an oblique prism is a prism in which the bases are parallel, but the faces are not directly one over the other.

The volume of an oblique prism is base area multiplied by the height.

$\text{Volume of an oblique prism}=\text{Base area* Height of the prism}$

We can see from our diagram that our prism has an square base as each side of base equals x units.

$\text{Base area of prism}=x\text{ units}*x\text{ units}$

$\text{Base area of prism}=x^2\text{ units}^2$

We can also see from our given diagram that it has a height of (x-2) units and slant height of (x+1) units.

Since volume of oblique prism is base area times by the height (not slant height). So upon substituting the height and base area of our given prism in volume formula we will get,

$\text{Volume of an oblique prism}=x^2\text{ units}^2*(x-2)\text{ units}$

$\text{Volume of an oblique prism}=x^2*(x-2)\text{ units}^3$

Therefore, the volume of our given prism is $x^2*(x-2)\text{ Cubic units}$ and option C is the correct choice.
