Consider the following function. g ( x ) = x 3 − 6 A) Find its average rate of change over the interval [ − 2 , 2 ] . B) Compare this rate with the instantaneous rates of change at the endpoints of the interval.
A- The average rate of change of g(x) over the interval [-2, 2] is 4, B- the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.
A) To find the average rate of change of the function g(x) over the interval [-2, 2], we need to compute the difference quotient:
average rate of change = [g(2) - g(-2)] / [2 - (-2)]
First, we find the values of the function at the endpoints of the interval:
g(-2) = [tex]-2^{3}[/tex] - 6 = -14
g(2) = [tex]2^{3}[/tex] - 6 = 2
Substituting these values into the
average rate of change = (2 - (-14)) / (2 - (-2)) = 16 / 4 = 4
Therefore, the average rate of change of g(x) over the interval [-2, 2] is 4.
B) To compare this rate with the instantaneous rates of change at the endpoints of the interval, we need to find the derivatives of the function at x=-2 and x=2 using the power rule of differentiation:
g'(x) = 3[tex]x^{2}[/tex]
g'(-2) = 3[tex]-2^{2}[/tex] = 12
g'(2) = 12
The instantaneous rate of change at x=-2 is 12, and the instantaneous rate of change at x=2 is also 12. These values are equal to the average rate of change over the interval [-2, 2], which is 4.
This means that the function g(x) is not a linear function over the interval [-2, 2], and the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.

Jessica makes $48,960.00 per year. She has a clothing budget of 5 % of her monthly budget. What was the average amount of money that Jessica's budget allowed for clothing the first six months of 2001?
Answer: Jessica's average clothing budget for the first six months of 2001 was $102.
Explanation: To calculate the average amount of money that Jessica's budget allowed for clothing in the first six months of 2001, we first need to find her monthly budget.
We can do this by dividing her annual salary by 12 (the number of months in a year):
$48,960 / 12 = $4,080 per month
Next, we need to find her clothing budget for one month. We're told that her clothing budget is 5% of her monthly budget, so we can calculate this as follows:
5% of $4,080 = (5/100) x $4,080 = $204
Therefore, Jessica's clothing budget for one month is $204.To find her average clothing budget for the first six months of 2001, we simply need to multiply her monthly clothing budget by the number of months (i.e., 6):
$204 x 6 = $1,224
Finally, we divide this total by the number of months to find the average: $1,224 / 6 = $102
Does (2, –2) make the equation y = –5x + –2 true? yes or no
(2, -2) does not make the equation y = -5x - 2 true.
Why it is and what is an equation ?
We can check if the point (2, -2) satisfies the equation y = -5x - 2 by plugging in the values of x and y and seeing if the equation is true:
y = -5x - 2
-2 = -5(2) - 2
-2 = -12
Since -2 is not equal to -12, the equation is not true for the point (2, -2). Therefore, (2, -2) does not make the equation y = -5x - 2 true.

At Silver Gym, membership is $45 per month, and personal training sessions are $25 each. At Fit Factor, membership is $75 per month, and personal training sessions are $15 each. In one month, how many personal training sessions would Sarah have to buy to make the total cost at the two gyms equal?
Answer:
3
Step-by-step explanation:
Set the equations. Let the variable x denote the amount of months that are needed.
Silver Gym:
In Silver Gym, the membership is a flat fee (constant) of $45, and training sessions are $25 for each session (25x, x denoting the amount of sessions).
Therefore, total cost is:
Total Cost (c) = Training session x Training cost per session + Flat Fee
or
c = 25x + 45
Fit Factor:
In Fit Factor, the membership is a flat fee (constant) of $75, and training sessions are $15 for each session (15x, x denoting the amount of sessions).
Therefore, the total cost is:
Total Cost (c) = Training session x Training cost per session + Flat Fee
or
c = 15x + 75
~
You are trying to solve for the amount of training sessions that have to be bought in which both prices will be the same. Note that both equations are equal to c. Based on the transitive property of equality, if a = b and b = c, then a = c. Therefore:
c = 25x + 45
c = 15x + 75
15x + 75 = c = 25x + 45
15x + 75 = 25x + 45
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 25x and 75 from both sides of the equation:
15x (-25x) + 75 (-75) = 25x (-25x) + 45 (-75)
15x - 25x = 45 - 75
-10x = -30
Next, divide -10 from both sides of the equation:
(-10x)/-10 = (-30)/-10
x = -30/-10 = 3

Define Moore’s law. How Moore’s law is associated with exponential function.
Moore's law is an observation made by Gordon Moore, co-founder of Intel Corporation, in 1965. It states that the number of transistors on a microchip doubles approximately every two years, while the cost of the chip is halved. Essentially, this means that computing power increases exponentially over time.
Moore's law is associated with exponential functions because it describes a situation in which a quantity (the number of transistors) grows at a rate proportional to its size, resulting in exponential growth. Exponential functions are often used to model phenomena in science, engineering, and other fields that exhibit this kind of behavior. In the case of Moore's law, the rate of growth is approximately 41% per year, or a doubling every 1.5 to 2 years. The formula for exponential growth is:
y = a * (1 + r)^tWhere:
y = the final amounta = the initial amountr = the annual growth ratet = the number of yearsMoore's law can be expressed using this formula as:
N = N0 * 2^(t / T)Where:
N = the number of transistorsN0 = the initial number of transistorst = the time elapsed since the initial observationT = the doubling time (approximately 2 years)For example, if a microchip had 1,000 transistors in 2000, according to Moore's law it would have 2,000 in 2002, 4,000 in 2004, 8,000 in 2006, and so on. The exponential function describes the growth of the number of transistors over time, and the formula allows us to predict future values based on past observations.

How do you know if a quadratic equation can be solved by factoring?
A quadratic equation can be solved by factoring if its coefficients are rational numbers and its discriminant, which is the expression under the square root in the quadratic formula, is a perfect square.
To determine if a quadratic equation can be solved by factoring, you must first ensure that its coefficients are rational numbers, meaning that they can be expressed as a ratio of two integers. Once you have confirmed this, you can calculate the discriminant of the quadratic equation, which is the expression b²-4ac, where a, b, and c are the coefficients of the quadratic equation in standard form.
If the discriminant is a perfect square, then the quadratic equation can be solved by factoring. If the discriminant is not a perfect square, then the quadratic equation cannot be solved by factoring using rational numbers, but may still be solvable using other methods, such as completing the square or the quadratic formula.

An angle measures 63.4° less than the measure of its supplementary angle. What is the measure of each angle?
The measure of the angles required are,
Angle A = 58.3deg
Angle B = 121.7deg
What are Supplementary Angles?If two angles sum up to 180 degrees, they are referred to as supplementary angles. When paired, supplementary angles result in a straight angle (180 degrees). In other words, if angle 1 plus angle 2 equals 180 degrees, angle 1 and angle 2 are supplementary. In this case, Angles 1 and 2 are referred to as "supplements" of one another.
Supplementary angles, by definition, add to to a sum of 180deg.
So what we know is:
Angle B + Angle A = 180deg
Angle B - 63.4deg = Angle A
By substitution:
Angle B + (Angle B - 63.4deg) = 180deg
Using the commutative property of addition, we can re-write the equation as:
(Angle B + Angle B) - 63.4deg = 180deg
We can add 63.4deg to both sides of the equation:
(Angle B + Angle B) - 63.4deg + 63.4deg = 180deg + 63.4deg
By simplifying, that gives us:
2(Angle B) = 243.4deg
Dividing both sides of the equation by 2, we can determine the measure of Angle B:
Angle B = 243.4deg/2 = 121.7deg
Now we have the measure of one of the angles, which we can plug back into our first equation:
Angle B + Angle A = 180deg
121.7deg + Angle A = 180deg
Subtracting 121.7deg from both sides, we get:
Angle A = 180deg - 121.7deg = 58.3deg
There’s your answer:
Angle A = 58.3deg
Angle B = 121.7deg

Now, Distance for the anchor drop every 5 seconds is,
Put t = 5;
E = - 2.4t + 75
E = - 2.4 × 5 + 75
E = - 12 + 75
E = 63 meters
