What is the average rate of change of the function f(x)=2(3)^x from x = 2 to x = 4?
The average rate of change of the given function will be 72.
What is the average rate of change of the function?It quantifies how much the function changed per unit on average throughout that time interval. The slope of the straight line connecting the interval's ends on the function's graph is used to calculate it.
The given function is f(x)=2(3)ˣ and the interval is x ∈ [2,4].
The formula to calculate the average rate of change is (f(b)-f(a))/(b-a).
Here, a = 2 and b = 4
So,f (2) = 2.3² = 18
Now,f (4) = 2.3⁴ = 162
The average rate of change = (162 - 18)/(4 - 2)
The average rate of change = 144/2
The average rate of change = 72
Therefore, the average rate of change of the given function will be 72.

The average rate of change of the function f(x) = 2(3)ˣ from x = 2 to x = 4 is 72. This means the secant line that intersects the graph of the function at x = 2 and x = 4 has a slope of 72.
Step 1: Formula for Average Rate of Change
The average rate of change of a function f(x) over the interval [a, b] is calculated using the following formula:
Average rate of change = (f(b) - f(a)) / (b - a)
where:
f(b) is the function's value at the upper bound (x = 4 in this case).f(a) is the function's value at the lower bound (x = 2 in this case).b is the upper bound of the interval (x = 4).a is the lower bound of the interval (x = 2).Step 2: Find f(b) and f(a)
We are given the function f(x) = 2(3)ˣ . Let's find the function's values at x = 4 (upper bound) and x = 2 (lower bound):
f(4) = 2(3)⁴ = 2 × 81 = 162f(2) = 2(3)⁴ = 2 × 9 = 18Step 3: Calculate the Average Rate of Change
Now that we have f(b) and f(a), we can plug them into the formula along with the interval's bounds:
Average rate of change = (f(4) - f(2)) / (4 - 2)Average rate of change = (162 - 18) / (2)Average rate of change = 144 / 2Average rate of change = 72Use the Laplace transform to solve the given initial value problem. y' + 6y = e^4t ; y(0)=2 ...?
The Laplace transform method is applied to solve the differential equation y' + 6y = e^4t with the initial condition y(0)=2. After transforming, simplifying, and solving for Y(s), we use inverse Laplace transform to find the solution y(t) in the time domain.
Explanation:Laplace transform is a powerful tool in the field of mathematics used for solving differential equations. To solve the given initial value problem y' + 6y = e^4t ; y(0)=2, we can start by taking the Laplace transform of both sides of the equation.
The Laplace transform of y' is sY(s) - y(0) and the Laplace transform of y is Y(s). Therefore, the Laplace transform of y' + 6y gives sY(s) - y(0) + 6Y(s). Given that y(0)=2, this simplifies to sY(s) + 6Y(s) - 2.
On the right-hand side, the Laplace transform of e^4t is 1/(s-4). Thus, we have the equation sY(s) + 6Y(s) - 2 = 1/(s-4).
By solving for Y(s), we can find the inverse Laplace transform to get the solution y(t) in the time domain.

Explain why all linear angle pairs must be supplementary, but all supplementary angles do not have to be linear pairs?
Final answer:
Linear angle pairs are always supplementary and formed by intersecting lines, while supplementary angles can be any two angles that add up to 180 degrees.
Explanation:
In mathematics, linear angle pairs are formed by two adjacent angles that add up to 180 degrees. This is known as supplementary angles. Linear angle pairs always occur when two lines intersect, creating opposite angles or a straight angle, such as in the case of a triangle.
On the other hand, supplementary angles do not have to be linear pairs. Supplementary angles are any two angles that add up to 180 degrees, regardless of their position or relation to each other. They can be adjacent angles, non-adjacent angles, or angles across parallel lines.
For example, two angles measuring 60 degrees and 120 degrees are supplementary angles but not a linear pair, since they are not adjacent to each other or formed by intersecting lines.

Which of the following are equivalent to the function y = 4cos x - 2? Check all that apply.
A. y = -4cos x + 2
B. y = 4sin(x +π/2 ) - 2
C. y = 4sin(x - π/2) - 2
D. y = 4cos(-x) - 2 ...?
Out of the given options, B (y = 4sin(x +ext{ extpi}/2 ) - 2) and D (y = 4cos(-x) - 2) are equivalent to the function y = 4cos x - 2, due to trigonometric identities and properties.
To determine which of the given options are equivalent to the function y = 4cos x - 2, we need to look at trigonometric identities and properties of cosine and sine functions.
Option A: y = -4cos x + 2 is not equivalent since it represents a reflection in the x-axis followed by a vertical shift, which alters the original function's graph completely.Option B: y = 4sin(x +rac{ext{extpi}}{2}) - 2 is equivalent because of the co-function identity sin(x + rac{ext{ extpi}}{2}) = cos x, which makes the functions identical.Option C: y = 4sin(x - rac{ext{extpi}}{2}) - 2 is not equivalent because sin(x - rac{ext{extpi}}{2}) is not equal to cos x.Option D: y = 4cos(-x) - 2 is equivalent due to the even property of the cosine function, which states that cos(-x) = cos x.

Which represents "The integer has one digit if and only if the integer is less than 10”?
p ∨ q
p ∧ q
p → q
p ↔ q
Answer:
p ↔ q
Step-by-step explanation:
Given :
Let p: The integer has one digit.
Let q: The integer is less than 10.
To Find:Which represents "The integer has one digit if and only if the integer is less than 10”?
Solution:
1. p ∧ q denotes “p and q”
2.p ∨ q denotes “p or q" (or both)
3.p → q denotes “if p then q”

A population of 240 birds increases at a rate of 16% annually. Jemel writes an exponential function of the form f(x) = abx to represent the number of birds after x years. Which values should she use for a and b?
Answer:
Hence the values of a and b are given by:
a=240
and b=1.16.
Step-by-step explanation:
It is given that:
A population of 240 birds increases at a rate of 16% annually.
i.e. the initial population of birds is 240.
Also they are increasing at a rate of 16% =0.16.
Hence, it clearly implies that the growth is exponential and the function that represents the population of the birds after x years is given by:
[tex]f(x)=240\times (1+0.16)^x\\\\\\f(x)=240\times (1.16)^x[/tex]
Hence, on comparing our function with the exponential function:
[tex]f(x)=ab^x[/tex]
we have:
a=240
and b=1.16.

If f(x) = 8, what is f(x) when x = 10? 4 9 13 36
If f(x) = 8, then f(x) when x = 10 is also 8, because the function's value is constant for all x.
Explanation:If the function f(x) is defined as f(x) = 8 for all values of x, then regardless of the value we substitute for x, the function's output remains constant at 8. So when x = 10, the value of f(x) is still 8. This is an example of a horizontal line on a graph where the y-value does not change regardless of the x-value. In terms of probability, if we're dealing with a continuous probability distribution where f(x) is a constant, then to find P(0 < x < a), we would simply evaluate the integral of f(x) over the interval from 0 to a. However, given that in this case f(x) is not a probability density function and is a constant value, P(x) would not be applicable.
What is 1036.50 rounded the the nearest whole number?
60% of what number is 13.5?
The required, 60 percent of 22.5 is equal to 13.5, as of the given condition.
What is percentage?The percentage is a way of expressing a fraction or a decimal number as a portion of 100. It is denoted by the symbol '%'. For example, the percentage of 0.75 can be calculated as 0.75 x 100% = 75%. In other words, we are expressing 0.75 as a fraction of 100.
Here,
To find out what number 60% of is equal to 13.5, we can use algebra. Let x be the number we are looking for. Then we can write:
60% of x = 13.5
We can convert 60% to a decimal by dividing by 100:
0.6x = 13.5
Finally, we can solve for x by dividing both sides of the equation by 0.6:
x = 13.5 ÷ 0.6
x = 22.5
Therefore, 60% of 22.5 is equal to 13.5.
