Find the average rate of change of f (x)=x-2√x on the interval [1, 9].
The average rate of change of f(x) = x - 2√x on the interval [1, 9] is 1/2.
What is average rate of change?It is a measure of how much the function changed per unit, on average, over that interval.
We have,
f(x) = x - 2√x
On the interval [1,9].
[1, 9] = [a, b]
The average rate of change:
= f(b) - f(a) / b - a
= f(9) - f(1) / 9 - 1
= [(9 - 2√9) - (1 - 2√1)] / 8
= [ (9 - 6) - (1 - 2) ] / 8
= (3 + 1) / 8
= 4 / 8
= 1/2
Thus the average rate of change of f(x) = x - 2√x on the interval [1, 9] is 1/2.

During a game of one-on-one, Rodney and Justin scored 39 points altogether. If Justin lost the game by 1 point, how many points did each player score? Use a system of linear equations in two variables to solve the problem
The points scored by Rodney is 20 points.
The points scored by Justin is 19 points.
How many points did each player score?x + y = 39 equation 1
x - y = 1 equation 2
Where:
x = points scored by Rodney
y = points scored by Justin
In order to determine the points scored by Justin, take the following steps:
Subtract equation 2 from equation 1 :
2y = 38
Divide both sides of the equation by 2
y = 38/2
y = 19 points
To determine the value of x, substitute for y in equation 2
x - 19 = 1
Combine similar terms: x = 19 + 1
Add similar terms together: x = 20

Answer:
4a.) 0.0005 = 5 x 10 to the exponent -4
4b.) 0.0025 = 2.5 x 10 to the exponent -3
5a.) 2 x 10 to the exponent -2 = 0.02
5b.) 16 x 10 to the exponent -4 = 0.0016
Tip:
The number being multiplied has to be less than or equal to 10. Count the places the decimal point moves from the end of the number to the number in the original equation.
Example: 0.05 = 5 x 10 to the exponent -2
0.05 has 2 spaces for the decimal point to move up to 5 going right. We use a negative decimal because 0.05 is less than 5. Here is an example where the exponent is positive:
5000 = 5 x 10 to the exponent 3
5000 has 3 spaces for the decimal point to move down to 5 going left.
A helicopter takes off from the roof of a building that is 225 feet above the ground. The altitude of the helicopter increases by 125
Answer: i think you want y=125x+225
Step-by-step explanation:
the linear equation is created by sticking these two numbers into y=mx+b
so we start at 225 feet, which means that goes where b is, and the helicopter goes up 125 per whatever, which means we put 125 where m is
Debra bought 4 hammers and 6 tape measures for $94. Heather bought 5 hammers and 3 tape measures for $77 . Letting x represent the price of each hammer and y represent the price of each tape measurewrite a cost equation for both Debra and Heather
The cost equation for Debra is given by 4x + 6y = 94 and for Heather is 5x + 3y = 77.
What are Linear equations in two variables?Linear equations in two variable have one, none, or infinitely many solutions, with the highest exponent order of 1 in each of the two variables. The standard form of a two-variable linear equation is ax + by + c = 0, where x and y are variables. Solutions can also be written in pairs, for example (x, y). A two-variable linear equation system is represented graphically by two straight lines that can intersect, parallelize, or coincide.
According to the given condition, we have 2 equations:
4x + 6y = 94
5x + 3y = 77
Now, multiply by 2 on both sides of the equation 5x + 3y = 77 to obtain:
10x + 6y = 154
Now, subtracting the equation 10x + 6y = 154 and 4x + 6y = 94.
[10x + 6y = 154] - [ 4x + 6y = 94]
6x + 0y = 60
x = 10
Putting the value of x = 10 in equation 4x + 6y = 94, we get
y = 9
So, the cost of 1 hammer is 10$ and tape is 9$.

a) What is P(1) if Rhonda chooses spinner A? P(1|A) = __
b) What is P(1) if Rhonda chooses spinner A? P(1|B) = __
c) Choose the correct symbol to make the statement true
Using probability we get (a) P(1|A) = 1/2 and (b)P(1|B) =3/4 , hence P(1|A) ≠ P(1|B).
Probability is the study of chance . The part of mathematics known as probability deals with fractional representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, 0 denotes the event's impossibility and 1 denotes certainty.
Probability is calculated by the fraction possible outcomes ÷ total outcomes
a) The first spinner has the total 4 sections. so there are 4 total outcomes.
Favorable outcome = 1
Total number of favorable outcome=2
Probability P(1|A) = favorable outcome ÷ total outcome
∴ P(1|A) =2/4 or P(1|A) =1/2
b) The first spinner has the total 4 sections. so there are 4 total outcomes.
Favorable outcome = 1
Total number of favorable outcome=3
Probability P(1|B) = favorable outcome ÷ total outcome
∴ P(1|B) =3/4 or P(1|B) =3/4
c)Therefore P(1|A)≠P(1|B) so the events A and B are dependent.

Write your answer as a fraction or whole number.
P(blue)=
The experimental probability of next person to have Blue eyes is 3/7.
Probability :Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
It is based on the possible chances of something to happen.
Probability (P) = Number of a Favourable outcome {n (E)} / Total number of outcomes {n (S)}
Simply, P = n (E) / n (S)
Given, Eye colors of the people
Green = 2
Blue = 30
Brown = 38
To find the probability of next person to have blue eyes, first we will add the given eye colors
Total number of Eye Colors = 2 + 30 + 38 = 70
Number of Blue Eyes = 30
Then, Probability to have blue eyes P(blue) = Number of Blue Eyes / Total number of Eye Colors

How to fine the line that is perpendicular to the given lineGiven data
line y = -x/8 + 3
The equation of a line is represented as y = mx + c where m represents the slope. The unique feature of perpendicular line is that the slopes are negative reciprocals of each other.
Hence we find the line that has same value of m which is the slope
using the second option: y - 8x = -2
y - 8x = 2
y = 8x - 2
y = 8x - 2

The average amount of soda consumed per person in the US from 1990 to 2010 can be modeled by the following equation, where x is the number of years since 1990. f(x) 5.852x^4-0.002x³ + 0.006x² + 0.029x + 47.855 Find the average rate of change for each time interval. a. 1990 to 1996 b. 1990 to 2000 c. 2005-2010
Using it's concept, the average rates of change are given as follows:
a. 1264.03 soda per person per year.
b. 5851.89 soda per person per year.
c. 128010.89 soda per person per year.
What is the average rate of change of a function?The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
For this problem, the function is given as follows:
f(x) = 5.852x^4 - 0.002x³ + 0.006x² + 0.029x + 47.855.
From 1990 to 1996, we have t = 0 to t = 6, hence:
f(0) = 47.855.f(6) = 5.852(6)^4 - 0.002(6)³ + 0.006(6)² + 0.029(6) + 47.855 = 7632.01.Hence the rate is:
(7632.01- 47.855)/6 = 1264.03.
1264.03 soda per person per year.
From 1990 to 2000, we have t = 0 to t = 10, hence:
f(0) = 47.855.f(10) = 5.852(10)^4 - 0.002(10)³ + 0.006(10)² + 0.029(10) + 47.855 = 58566.75.Hence the rate is:
(58566.75 - 47.855)/10 = 5851.89.
5851.89 soda per person per year.
From 2005 to 2010, we have t = 15 to t = 20, hence:
f(15) = 5.852(15)^4 - 0.002(15)³ + 0.006(15)² + 0.029(15) + 47.855 = 296300.39.f(20) = 5.852(20)^4 - 0.002(20)³ + 0.006(20)² + 0.029(20) + 47.855 = 936354.84.Hence the rate is:
(936354.84 - 296300.39)/5 = 128010.89.
