What is the average rate of change of the function f(x)=5(2)xfrom x = 1 to x = 5? enter your answer in the box.
The average rate of change is 37.5.
Define Rate of change
Rate of change (ROC) refers to how quickly something changes over time.The acceleration or deceleration of changes (i.e., the rate) and not the magnitude of individual changes themselves.Formula is, Rate of change = ( f(b) - f(a) ) / (b - a)Given function is,
f(x) = 5(2) ^ x
where, x = 1 to x = 5
We know, the formula of rate of change is
Rate of change = ( f(b) - f(a) ) / (b - a)
for x = 5, for that put value of x in given function
f(x) = 5(2) ^ x
f(5) = 5(2) ^ 5
f(5) = 160
for x = 1, for that put value of x in given function
f(x) = 5(2) ^ x
f(1) = 5(2) ^ 1
f(1) = 10
Now, plug in the values in rate of change formula
Rate of change = ( f(5) - f(1) ) / (5 - 1)
= ( 160 - 10) / 4
= 150 / 4
= 37.5
Hence, the average rate of change is 37.5

Can you use a right triangle to represent the distance between any two points on the coordinate plane?.
Yes. A leg of a right triangle can indicate the distance that separates two vertical or horizontal points, and the hypotenuse can represent the distance between two non-vertical or non-horizontal points.
We can use this theorem to calculate the distances between two locations on a coordinate grid. Consider the following example using the points:
( 3, 4 ) and ( − 2, 1 )
We can see how to make a right triangle with the hypotenuse as that of the line connecting these two spots. A right angle is formed at the coordinates ( 3, 1), where the vertical line from ( 3, 4 ) and the horizontal line from ( 2, 1 ) intersect.

How do you calculate obtuse value?.
Calculating the obtuse angle or value of a triangle.
Finding obtuse angle value:
steps:
1) Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together.
For example, if the lengths of the sides measure 4 and 2, then squaring them would result in 16 and 4. Adding the squares together results in 20.
2) Square the length of the side opposite the obtuse angle. For the example, if the length is 5, then squaring it results in 25.
3) Subtract the combined squares of the adjacent sides by the square of the side opposite the obtuse angle. For the example, 25 subtracted from 20 equals -5.
4) Multiply the lengths of the adjacent sides together, and then multiply that product by 2. For the example, 4 multiplied by 2 equals 8, and 8 multiplied by 2 equals 16.
5) Divide the difference of the sides squared by the product of the adjacent sides multiplied together then doubled. For the example, divide -5 by 16, which results in -0.3125.
The obtuse angle value is obtained by inverse of cos:
cos^-1(-0.3125)
= 108.209 degrees.

What does variability mean in mean absolute deviation?.
The mean absolute deviation (MAD), a measure of variability, illustrates the typical distance between an observation's mean and its variation. MAD uses the data's original units to facilitate interpretation.
Greater values indicate a wider range of data points than the average. The term "variability" refers to how much a data collection varies from one constituent to another. Variability measures reflect the level and magnitude of change within the data collection.
The interquartile range and the mean average deviation are the two methods for calculating variability that are required by the requirements for sixth-grade pupils.
The majority of the data values are fairly near to the mean, as shown by a tiny mean absolute deviation. We can infer from a large mean absolute deviation that numerous data values are dispersed widely from the mean.

just designed a cloister (a rectangular garden surrounded by a covered walkway on all four sides). the outside dimensions of the garden are 12 feets by 8 feet, and the area of the garden and the walkway together are 252 square feet. what is the width of the walkway?
The width of the rectangular walkway is 3 feet around.
The walkway has a uniform width around the rectangle.
Let the width of walkway be x
The total length of the garden and walkway will be (12+2x) feet
The total width of the walkway and garden would be (8+2x) feet
Area of the garden and the walkway together are 252 square
Let’s express this mathematically:
(8+2x)(12+2x) = 252
Let’s open the brackets;
96+ 16x+ 24x + 4x^2 = 252
4x^2 + 40x + 96 = 252
4x^2 + 40x + 96-252 = 0
4x^2 + 40x - 156 = 0
Let’s divide all through by 10. We have;
x^2 + 10x -39 = 0
X^2 +13x-3x-39 = 0
x(x + 13) -3(x+ 13) = 0
(x-3)(x + 13) = 0
x -3 = 0 or x + 13 = 0
x = 3 or -13

Step-by-step explanation:
The slope of 2x is a positive slope so it can't be line d(which is negative) or line c(which is horizontal).
That leaves us with lines a and b. 2x is a steep slope and line a has a steep slope while line b has a shallow slope so it is line a.

Based on the frequency distribution above, find the relative frequency for the class with lower class limit 31
Relative Frequency = %
Give your answer as a percent, rounded to one decimal place
The required relative frequency based on the frequency distribution of the students is 8.33%
The relative frequency is the frequency fraction of the number of observations the events occur to the total number of observations. The relative frequency provides a clear understanding of the distribution. This also helped to make a histogram and chart.
The number of times a value appears in a dataset is its frequency. The pattern of frequencies for a variable is known as a frequency distribution. The frequency with which each potential value of a variable appears in a dataset.
The frequency distribution is given.
Total number of student=36
The relative frequency for the class with lower-class limit 31 is calculated as;
R.F=No. of students in class interval/Total no.of students
=3/36
=0.0833
=8.33%

A veterinarian uses weights in kilograms to figure out what dosages of medicines to prescribe for animals. For every 10 kilograms, there are 22 pounds. Calculate this animal’s weight in kilograms and explain your reasoning.
Fido the Labrador weighs 88 pounds.
The required weight of fido the labrador is 40 kilogram.
What is relation between kilogram and pound?
kilogram is the fundamental unit used to measure weight ans pound is used in UK to measure weight of any object.
As we have given in 10 kilogram, there are 22 pounds. So, one kilogram is equal to 2.2 pound.
According to given data in the question:We have to find the weight of fido the labrador in kilogram
here,weight in pound is 88
we know that one pound contain 1/2.2 kilogram
So, weight of 88 pound in kilogram = (88)1/2.2
weight in kilogram = 40 kilograms.
Hence, the required answer is 40 kilogram.

the drive time for a college student commuting between her dorm and her coop job is uniformly distributed between 20 and 45 minutes. the probability that she will get to work in 30 mins or less is
The probability that a college student will get to work in 30 mins or less is 0.4 or 40%.
What does uniformly distributed probability mean?
Uniform distribution refers to a type of probability distribution in which all outcomes are equally likely to occur.
According to the given question:
Since the time is uniformly distributed, every possible travel time has the same likelihood of occurring.
Lower boundary (L) = 20 minutes
Upper boundary (U) = 45 minutes
The probability that a student finishes her trip in 30 minutes or less is:
P (t ≤ 30) = (30 - L)/(U - L)
= (30 - 20)/(45 - 20)
= 10/25
= 0.4 or 40%
The probability that she will get to work in 30 mins or less is 0.4 or 40%
