The value of d/dx (fourth root 5x) is 5/4x^-1/3
What is differentiation?Differentiation is a method used to compute the rate of change of a function f(x) with respect to its input x . This rate of change is known as the derivative of f with respect to x .
Differentiation is used to determine the instantaneous rate of change of quantities. For instance, if we want to find the velocity of a car, we can do it by using differentiation. Mathematically, it is expressed as v = d s /d t , where s is displacement and t is time.
if y =x^n
dy/dx = nx^n-1
therefore to find d/dx(fourth root 5x)
fourth root 5x = 5x^1/4
= d/dx(5x^1/4)
=1/4×5x^1/4-1

let $k$ be the product of all factors $(b - a)$ (not necessarily distinct) where $a$ and $b$ are integers satisfying $1 \le a < b \le 20$. find the greatest positive integer $n$ such that $2^n$ divides $k$.
The greatest positive integer [tex]$n$[/tex] such that [tex]$2^n$[/tex] divides [tex]$k$ is $n = 4$[/tex].
[tex]$k = (2 - 1)(3 - 1)(4 - 1)...(20 - 1)$[/tex]
We can rewrite [tex]$k$[/tex] as [tex]$k = 2^1 \cdot 3^1 \cdot 4^1 \cdot ... \cdot 20^1$[/tex], and then use the formula [tex]$2^n \mid (p_1^{\alpha_1} \cdot p_2^{\alpha_2} \cdot p_3^{\alpha_3} \cdot ... \cdot p_m^{\alpha_m})$ $\iff$ $2^n \mid p_1^{\alpha_1}$[/tex] and [tex]$2^n \mid p_2^{\alpha_2}$[/tex] and[tex]$2^n \mid p_3^{\alpha_3}$ and ... and $2^n \mid p_m^{\alpha_m}$[/tex]
Since all of the exponents [tex]$\alpha_1, \alpha_2, \alpha_3, ..., \alpha_m$[/tex] are equal to 1, we can simplify this to: [tex]$2^n \mid p_1$ and $2^n \mid p_2$ and $2^n \mid p_3$ and ... and $2^n \mid p_m$[/tex]
In this case, [tex]$p_1 = 2$, $p_2 = 3$, $p_3 = 4$[/tex], and so on, so [tex]$2^n$[/tex] must divide all of the prime numbers from 2 to 20 in order for it to divide k.

A car dealership has been keeping detailed records of the colors of cars sold during the current year. This chart shows the probabilities for each color.
What is the probability that for the next two cars sold, the first will be black and the second will be silver?
The requried probability that for the next two cars sold, the first will be black and the second will be silver is 41%.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
To find the probability that a customer will purchase a silver or white car, we add the probabilities of each individual color:
silver = 23%
white = 18%
silver or white = 23% + 18% = 41%
So, the probability that a customer will purchase a silver or white car is 41%.

two marbles are drawn at random and without replace- ment from a box containing two blue marbles and three red
The probability of drawing one blue marble and one red marble is thus 6/25 or 24%.
The probability of drawing two marbles from a box containing two blue marbles and three red marbles is calculated as follows. The total number of possible outcomes is calculated by multiplying the number of marbles in the box (2 blue and 3 red) by the number of marbles drawn (2): 5 x 5 = 25. The number of possible outcomes in which two blue marbles are drawn is calculated by multiplying the number of blue marbles in the box (2) by the number of marbles drawn (2): 2 x 2 = 4. The probability of drawing two blue marbles is thus 4/25 or 16%. Similarly, the probability of drawing two red marbles is 12/25 or 48%. The probability of drawing one blue marble and one red marble is calculated by multiplying the number of blue marbles in the box (2) by the number of red marbles in the box (3): 2 x 3 = 6. The probability of drawing one blue marble and one red marble is thus 6/25 or 24%.

Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. (Round your answer to three decimal places.)
Radius r Arc Length s Central Angle θ
86 km 166 km radians
The central angle of the circle with a radius of 86 km that intercepts an arc of length 166 km is approximately 3.142 radians.
The formula for the central angle of a circle given the arc length is:
θ = 2 * arccos(s/(2 * r))Plugging in the given values, we get:
θ = 2 * arccos(166/(2 * 86))
= 2 * arccos(1)
= 2 * 90°
= 180°
= 3.142 radians (rounded to three decimal places)
So the central angle of the circle with a radius of 86 km that intercepts an arc of length 166 km is approximately 3.142 radians. The central angle of a circle given arc length is given in the formula; for a given 86 km radius & 166 km arc, the central angle is approximately 3.142 radians.

The researcher decided to make the number of parties attended per week the explanatory variable and the number of text messages sent per day the response variable. The least squares regression line for this relationship is y-hat = 64.96 + 25.41x. Interpret the y-intercept if appropriate. 1000 2002 Legend Fitted line Parties Do not interpret. The predicted number of text messages per day for someone who has not attended a party this week is 64.96. The predicted number of text messages per day for someone who has not attended a party this week is 25.41. The predicted number of parties attended this week for someone that hasn't sent any text messages is 64.96. The predicted number of parties attended this week for someone that hasn't sent any text messages is 25.41.
The predicted number of text messages sent per day for someone who has not attended a party this week is 64.96 and the predicted number of text messages sent per day for someone who has attended one party this week is 90.37 (64.96 + 25.41).
The least squares regression line is a mathematical formula that is used to predict the response variable (in this case, the number of text messages sent per day) based on the explanatory variable (the number of parties attended per week). The formula for the least squares regression line is y-hat = b0 + b1x, where y-hat is the predicted response variable, b0 is the y-intercept, b1 is the slope, and x is the explanatory variable. In this example, the y-intercept is 64.96 and the slope is 25.41. This means that the predicted number of text messages sent per day for someone who has not attended a party this week is 64.96 and the predicted number of text messages sent per day for someone who has attended one party this week is 90.37 (64.96 + 25.41).

Carrying capacity is the value of p where [tex]0.1p-0.00025p^{2} =0[/tex]. Soln: increasing between 0 and K, decreasing when p > K.
The largest population that can be supported in a certain ecosystem is known as the carrying capacity. It can be found by setting the derivative of the logistic equation to zero, which represents the maximum population growth rate. The carrying capacity of the logistic equation, [tex]0.1p-0.00025p^{2} =0[/tex], can be found by solving for p when the derivative is equal to zero. The solution is p = 40,000.
When t is between 0 and the carrying capacity, the population is increasing because the derivative of the logistic equation is positive. When t is greater than the carrying capacity, the population is decreasing because the derivative of the logistic equation is negative.
The logistic equation represents the growth of a population with time, where p is the population size, and t is measured in weeks. The carrying capacity is the maximum population size that can be sustained in the environment and is given by the value of p that makes the right-hand side of the equation equal to 0. The solution is increasing when t is between 0 and the carrying capacity, and decreasing when t is greater than the carrying capacity.

The distance along an arc on the surface of the earth is 4.605miles
What is length of an arc?Given an angle and the diameter of a circle, we can calculate the length of the arc using the formula: Arc Length = ( 2 * pi * radius ) * ( angle / 360 ) Where pi = 22/7, diameter = 2 * radius, angle is in degree.
1 minutes = 1/60 degree
4 minutes = 1/60 × 4
4 minutes = 1/15 °
l = tetha/360 × 2πr
l = 1/15 × 1/360 × 2 × 3.14 × 3960
