The values of P and a that will make f(x)=Pa^x to be an exponential growth function is; A P = 1²; a = 2
How to identify an exponential growth function?The general formula for exponential growth function is;
y = a(b)ˣ
When a is a positive value and 'b' is the base greater than 1,
In order to represent exponential growth, a must be a positive number larger than 1. If a is a fraction less than 1, we are basically taking a percent (less than 100) of the number and this will make it smaller, which would the become a decay function. If a is a negative, the values would alternate between positive and negative.
The only option where a is a positive number larger than 1 is P = 1²; a = 2

Need to explain a bit on why the answer is 11.95. Show work
Explanation:
Use the trigonometric ratio cosine.
Remember that [tex]\cos(x) = \dfrac{\textrm{adjacent}}{\textrm{hypotenuse}}[/tex].
So, we can construct the following equation using the given triangle:
[tex]\cos(23\textdegree)=\dfrac{11}{x}[/tex]
And solve for x. First, take the reciprocal of both sides (flip both sides).
[tex]\dfrac{\cos(23\textdegree)}{1}=\dfrac{11}{x}[/tex]
↓
[tex]\dfrac{1}{\cos(23\textdegree)}=\dfrac{x}{11}[/tex]
Then, multiply both sides by 11.
[tex]11\cdot\left(\dfrac{1}{\cos(23\textdegree)}\right)=\left(\dfrac{x}{11}\right) \cdot 11[/tex]
[tex]\dfrac{11}{\cos(23 \textdegree)} = x[/tex]
[tex]x = \dfrac{11}{\cos(23 \textdegree)}[/tex]
Finally, plug this fraction into your calculator as 11/cos(23) to get approximately 11.95.
Also, make sure that your calculator's mode is degrees, NOT radians.
Express the given in terms of the logarithms of prime numbers:
The expression of log₄405 in terms of the logarithms of prime numbers is; 4 log₄3 + log₄ 5
How to use laws of logarithm?One of the laws of logarithm is that;

Now, we are given the logarithmic expression as; log₄405
We can express 405 in terms of prime numbers as;
405 = 81 * 5 = 3⁴ × 5
Thus, we have;
log₄405 = log₄(3⁴ × 5)
Since log (a * b) = log a + log b, then;
log₄(3⁴ × 5) = log₄3⁴ + log₄ 5
= 4 log₄3 + log₄ 5

La altura de un prisma de base cuadrada es de 15 cm. Si el lado de la base cambia de 10 a 10.02 cm, utilizando diferenciales, calcular el cambio aproximado de su volumen sabiendo que V (x) = 15x2
Según el método de diferenciales, el cambio aproximado del volumen del prisma es aproximadamente igual a 60 centímetros cúbicos.
¿Cómo determinar el cambio del volumen mediante diferenciales?
Las diferenciales son una generalización del concepto matemático de cambio para funciones de una o más variables. Las versiones de una sola variable involucran derivadas ordinarias, mientras las versiones multivariables utilizan derivadas parciales.
El volumen del prisma es igual al producto del área de la base (A), en centímetros cuadrados, y la altura (h), en centímetros.
V(h, A) = h · A
El área de la base es igual al área de un cuadrado, es decir:
A(x) = x²
Donde x es la longitud del lado, en centímetros.
Según el enunciado, la altura del prisma es constante, mientras la longitud del lado de la base es una variable. En consecuencia, tenemos un diferencial que emplea derivadas ordinarias, esto es:
ΔV = (dV / dx) · Δx
V(x) = 15 · x²
dV / dx = 30 · x
Si sabemos que x = 10 cm y Δx = 0.02 cm, entonces el cambio en el volumen del prisma es:
ΔV = 30 · (10 cm)² · (0.02 cm)
ΔV = 60 cm³

Select the correct values. if the area (in square units) of the region under the curve of the function f(x) = 3x − 1 on the interval [a, 4], where a < 4, is 12 square units, identify all the possible values of a.
Answer:
-2, 8/3
Step-by-step explanation:
You can consider the area to be that of a trapezoid with parallel bases f(a) and f(4), and width (4-a). The area of that trapezoid is ...
A = (1/2)(f(a) +f(4))(4 -a)
= (1/2)((3a -1) +(3·4 -1))(4 -a)
= (1/2)(3a +10)(4 -a)
We want this area to be 12, so we can substitute that value for A and solve for "a".
12 = (1/2)(3a +10)(4 -a)
24 = (3a +10)(4 -a) = -3a² +2a +40
3a² -2a -16 = 0 . . . . . . subtract the right side
(3a -8)(a +2) = 0 . . . . . factor
Values of "a" that make these factors zero are ...
a = 8/3, a = -2
The values of "a" that make the area under the curve equal to 12 are -2 and 8/3.
Alternate solution
The attachment shows a solution using the numerical integration function of a graphing calculator. The area under the curve of function f(x) on the interval [a, 4] is the integral of f(x) on that interval. Perhaps confusingly, we have called that area f(a). As we have seen above, the area is a quadratic function of "a". I find it convenient to use a calculator's functions to solve problems like this where possible.

There are 14 members in the club, and there are 4 leadership positions. Each position can be filled by any of the 14 members, so there are 14 ways to fill the first position, 14 ways to fill the second position, and so on. However, we have overcounted because we have not taken into account that a member cannot serve in two positions simultaneously. To correct for this overcounting, we divide by the number of ways that a member can serve in two positions simultaneously, which is 1. Therefore, the total number of ways that the club leadership can be organized is:
14 * 14 * 14 * 14 / 1 = 14^4 = 20736 ways.

What are complementary and supplementary angles? How do you find the measure of an unknown angle using these relationships? Give an example and show your work.
Two angles are called complementary when their measures add up to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
Complementary angles add up to 90°- example: 15° & 75° are complimentary
For example:
Suppose if one angle is x then the other angle will be 90° – x.
Now, to find the complement of 2x + 52°, subtract the given angle from 90 degrees.
90o – (2x + 52o) = 90o – 2x – 52o = -2x + 38o
The complement of 2x + 52o is 38o – 2x.

What is the slope of the line that fits Bryce's data?
y = 7 x is the situation's linear equation in two variables and 7 is Slope of line.
How to calculate Slope?To determine a line's inclination or steepness, use the slope formula. By calculating the ratio of the change in the y-axis to the change in the x-axis, it may be used to calculate the slope of any line. A line's slope is determined by how its "y" coordinate changes in relation to how its "x" coordinate changes.
Calculation:The faucet leakage rate is shown here to be 7 gallons per hour.
Since y gallons could leak in x hours , we have
Leakage rate is expressed as gallons per hour divided by the number of hours.
Given that our leakage was y gallons, and
The duration of the leaking is x hours, as well.
7 gallons per hour is the leakage rate, so we have;
Amount of gallons leaked = Gallons leaking per hour × Number of hours
The situation is represented by the linear equation =
y = 7 × x.
By comparing this with y=mx+c, Slope of line is 7
y = 7 x is the situation's linear equation in two variables and 7 is Slope of line.

consider the words consisting of 5 letter "a"'s, 7 letter "b"'s, and 1 letter "c". find the number of such words where there are no two consecutive "b"'s.
Answer:
To avoid consecutive b's, the string of b's must be divided into one or more groups of 1, 2, or 3 b's. There are a total of 5 + 1 = 6 possible places to insert the dividers to create these groups. For example, suppose we have a string of 7 b's and we insert dividers between the 3rd and 4th b's, and between the 5th and 6th b's. This would create the following groups of b's: bb|bb|b. In general, the number of possible ways to divide the string of b's into groups of 1, 2, or 3 b's is equal to the number of ways to insert 6 dividers into a string of 7 b's. This is equal to the number of ways to choose 6 of the 8 possible places to insert the dividers, which is equal to $\binom{8}{6} = 28$.
Since the 5 a's and the 1 c must be arranged in a specific order, there is only 1 way to arrange these letters. Therefore, the total number of words consisting of 5 letter a's, 7 letter b's, and 1 letter c is equal to $1 \times 28 = 28$.
Answer:
6 possible words.-----------------------------------------------
According to the question there are 7 'b' s and we can't have them together. We assume more than two consecutive 'b' s contain two consecutive 'b' s and hence not considering any option of having 3, 4, 6 or 7 'b' s.
There is only one way to place 'b' s apart which leaves us with 6 gaps.
There are 5 + 1 = 6 other letters which is just the number to fill in the gaps between 7 'b' s.
We have only an option for 'c' to have any of the 6 gaps, it gives us 6 options and no other options for 'a' s.
Therefore in total we have 6 possible ways.

The percentile rank of score 71 on the test is 26.7 and The score of the 60th percentile on the test is 84.
What is a percentile?The figure that a particular percentage falls within is referred to as the percentile. For instance, 80% of the kids in a group of 20 are shorter than you, and Ben is the fourth tallest.
Given:
58, 64, 66, 70, 71, 75, 77, 80, 84, 85, 87, 90, 93, 95, 96
Calculate the percentile of score 71 as shown below,
[tex]Percentile= n / N \times 100[/tex]
Here, n is the number of scores below 71 and N is the total number of scores,
Percentile = 4 / 15 × 100
Percentile = 0.267 × 100
Percentile = 26.7 percentile
Therefore, the percentile rank of score 71 on the test is 26.7
(B)
Substitute the value in the formula given below,
60 = n / 15 × 100
n / 15 = 60 / 100
n = 0.6 × 15
n = 9
Thus, the 9th term here is 84,
Therefore, the score of the 60th percentile on the test is 84.

→ [ x = 2 ]
Hence, the value of x is 2.
as it reaches the point (1, 5), the y-coordinate is increasing at a rate of 4 cm/s. how fast is the x-coordinate of the point changing at that instant?
The rate of increase of the y-coordinate as it approaches the point (1, 5) is 4 cm/s.At that instant, the x-coordinate of the point is not changing; it is staying at 1.
When a point reaches a certain coordinate, it means that the point is not changing anymore. In this case, the point has reached the coordinate (1, 5), which means that the x-coordinate (1) is not changing, while the y-coordinate (5) is increasing at a rate of 4 cm/s. Therefore, the x-coordinate of the point is not changing at that instant.
x = 1
Rate of Change (x-coordinate) = 0 cm/s

The solution of the z-score of the standard deviation is [tex]0.5[/tex].
What is the standard deviation?
The standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
Here given that,
The weight for twelve month old baby boys are normally distributed wih the mean [tex]22.5[/tex] pounds and a standard deviation of [tex]2.2[/tex] pounds.
Here, [tex]mean=22.5[/tex] , standard deviation [tex]=2.2[/tex]
z-score = (Blood pressure reading - mean)/standard deviation
[tex]=\frac{23.6=22.5}{2.2}\\\\=\frac{1.1}{2.2}\\\\=0.5[/tex]
Hence, the percentage is [tex]0.5[/tex].
