Answers
The required answer choices are (i)exponential decay (ii) linear and (iii) exponential growth
What are exponential growth and exponential decay?
Quantities that fluctuate quickly are subject to exponential growth and decay. The idea of geometric progression has been used to infer exponential growth and decay. Exponential growth or exponential decay are terms used to describe quantities that vary exponentially rather than continuously.
From question,
1) The first question is like, initially delivery van price is $25,000 after 2 years, the value of the van becomes $17,500
This means it is decaying. The difference between the initial price and after 2 years price is $7500.
To be linear, further after 2 years, or from start after 6 years, the price should be $10000. But it is given to be $12250.
Thus exponential decay.
2) In the second, Initially, a laptop had 100% battery life. After 3 hours, the laptop has 60% battery life. Thus the loss in 3 hours is (100 - 60) = 40%.
After 4 hours, the loss is (60 -20) = 40%
As the loss is the same in equal intervals of time, the decay is linear.
3) In the third one, A tiger reserve had an initial population of 20 tigers.
After 5 years the population was 30 tigers, thus the growth is (30-20) =10.
After 10 years, the population was 45 tigers. Thus the growth is (45-30) = 15.
Thus the increase is non-linear, and so is exponential growth.

What is value ?
Value in mathematics can refer to a number of closely related ideas. A mathematical value can generally be any specific mathematical object. This is most frequently a number in elementary mathematics, such as a real number like or an integer like 42.
Depending on where it is in the number, each digit has a different value, which is referred to as value. We figure it out by multiplying the digit's place value by its face value. Place value plus face value equals value. Consider the number 45, for example. Here, the fourth digit is in the tens column.
If triangle is isosceles it means the two sides and angles are equal
∴ BC = AC
AC = 8 cm

Answers
Answer:
(-5, 0)
|z| = 5
Step-by-step explanation:
Complex numbers can be represented on an Argand diagram.
The x-axis is called the real axis and the y-axis is called the imaginary axis.
The complex number z = x + iy is represented on the diagram by the point P(x ,y), where x and y are Cartesian coordinates.
Therefore, the complex number z = -5 can be represented on the Argand diagram by the point:
(-5, 0)The absolute value of a complex number is the magnitude of its corresponding vector.
For a complex number z = x + iy, the absolute value is given by:
[tex]|z|=\sqrt{x^2+y^2}[/tex]
Therefore, the absolute value of complex number z = -5 is:
[tex]\implies |z|=\sqrt{(-5)^2+(0)^2}[/tex]
[tex]\implies |z|=\sqrt{25+0}[/tex]
[tex]\implies |z|=\sqrt{25}[/tex]

Answers
Hello,
I hope you and your family are doing well!
To solve this problem, you need to set up a proportion using the information given in the problem. Let x represent the number of miles the family will travel during the next 4 hours. The proportion will look like this:
318 miles / 6 hours = x miles / 4 hours
To solve for x, you can cross-multiply and solve the equation:
318 miles / 6 hours = x miles / 4 hours
6 hours * 318 miles = 4 hours * x miles
1848 miles = 4x miles
x = 462 miles
Therefore, if the family continues at the same rate, they will travel a total of 462 miles during the next 4 hours.

Robin worked his 40 regular hours last week plus 20 overtime hours at the time-and-a-half rate. His gross pay was $16,203. What is his regular hourly rate?
Answers
Answer:
His rate is a whopping $231.47 per hour.
:)
Step-by-step explanation:
We can conclude that.
[tex]r*t_1=p_{reg}[/tex] is the gross pay from his regular hours.
[tex]1.5r*t_2=p_{ovt}[/tex] is the gross pay from his overtime hours.
So all together we can say
[tex](r*t_1)+(1.5r*t_2)=p[/tex]
We are looking for his hourly rate.
Lets solve for [tex]r[/tex].
Multiply the terms in the parenthesis.
[tex]rt_1+1.5rt_2=p[/tex]
Factor [tex]r[/tex] out of [tex]rt_1[/tex].
[tex]r(t_1)+1.5rt_2=p[/tex]
Factor [tex]r[/tex] out of [tex]1.5rt_2[/tex].
[tex]r(t_1)+r(1.5t_2)=p[/tex]
Factor [tex]r[/tex] out of [tex]r(t_1)+r(1.5t_2)[/tex].
[tex]r(t_1+1.5t_2)=p[/tex]
Divide each term in [tex]r(t_1+1.5t_2)=p[/tex] by [tex]t_1+1.5t_2[/tex] and simplify.
[tex]\frac{r(t_1+1.5t_2)}{t_1+1.5t_2} =\frac{p}{t_1+1.5t_2}[/tex]
Simplify the left side. Cancel the common factor of [tex]t_1+1.5t_2[/tex]
[tex]r=\frac{p}{t_1+1.5t_2}[/tex]
Now we have an equation to find his regular hourly rate.
We are given
[tex]p=16203[/tex]
[tex]t_1=40[/tex]
[tex]t_2=20[/tex]
Lets plug these numbers into our equation for [tex]r[/tex].
[tex]r=\frac{16203}{40+1.5*20}[/tex]
[tex]r=\frac{16203}{70}[/tex]
[tex]r=231.47[/tex]

2)Solve the differential equation
3) Evaluate the solution at the specified value of the independent variable. (Round your answer to three decimal places.)

What is meant by differential equation?In practical contexts, derivatives frequently represent the rates of change of physical quantities, and the differential equation establishes a relationship between the two. As a result of the frequent occurrence of these correlations, differential equations are widely employed in a wide range of disciplines, including engineering, physics, economics, and biology.
Only the simplest differential equations can be resolved explicitly, but many aspects of a given differential equation's solutions can be determined without doing an exact calculation.
1) The differential equation is: dP/dt=kP
Here k is the proportionality constant
2) Now, we have to solve the differential equation on dP/dt=kP
∫dP/P=∫kdt+lnP₀
lnP₀=kt+lnP₀
lnP/P₀=kt
P=P₀[tex]e^{kt}[/tex]
Here P₀ is the constant of integration.
P(t)=P₀[tex]e^{kt}[/tex]
And they have given that,
P(0)=8000=P₀e⁰
P₀=8000
P(1)=5200
5200=8000[tex]e^{k}[/tex]
k=-2log(2)+log(3)≈ -0.28
Therefore, the required function is:
P(t)=8000[tex]e^{-0.28t}[/tex]
3) Now, we have to put t=6 in the above equation:
P(6)=8000[tex]e^{-0.28*6}[/tex]

A response variable can be described in terms of a linear combination of predictor variables using linear models. The response ought to be continuous and at least roughly regularly distributed. Although these models are widely used, they are unable to handle clearly discrete or skewed continuous data.
In the table, we see that as x increases, y values change in a steady manner. The slope of this function is approximately 1860.
We use straight lines to visually illustrate linear relationships. Typically, a linear model has two parameters: the slope, also known as the growth factor or rate of change, and the y-intercept, often known as the beginning value. The linear model can be expressed as a linear function, y = mx + b or y=mx+b, where m is the slope and b is the y-intercept.

0.48 ln(x+2)=28-27
ln(x+2)=1/0.48
ln(x+2)=2.08
[tex]\rm x+2 = e^{2.08}[/tex]
x+2 = 8.004
x=8.004 - 2
x=6.004
Thus, for the given function, f(x)=0.48 ln (x+2)+27. The distance is 6.004 from the eye is the pressure of 28 inches of mercury.

Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 526
randomly selected adults showed that 61% of them would erase all of their personal information online if they could. Find
the value of the test statistic.
The value of the test statistic is
(Round to two decimal places as needed.)
Answers
The value of the test statistic rounded to two decimal places is equal to 5.05.
What is a sample proportion?In Mathematics, a sample proportion can be defined as the proportion of individuals in a sample that have a specified characteristic or trait.
For a claim that most adults would erase all of their personal information online if they could, the appropriate null hypothesis and alternative hypothesis would be given by this mathematical expression:
H₀: p ≤ 0.5.
Ha: p > 0.5.
How to calculate the value of the test statistic?Mathematically, the test statistic for the z-test of a population proportion can be calculated by using this mathematical expression;
[tex]z=\frac{\hat{p} \;- p}{\sqrt{\frac{p(1\;-p)}{n } } }[/tex]
Where:
z represents the test statistic.p^ represents the sample proportion.n represents the sample size.p represents the population proportion.Substituting the given parameters into the formula, we have;
z = (0.61 - 0.5)/√(0.5(1 - 0.5)/526)
z = (0.11)/√(0.5(0.5)/526)
z = (0.11)/√(0.25/526)
z = 0.11/0.0218
z = 5.05.

A. The farmer needs 96 crates to ship out all apples. False
B. The farmer needs 97 crates to ship out all the apples. True
C. At least one of the crates will not be filled to capacity. True
D. To determine the number of crates needed, divide 30 by 2,903. False
Answer:
A. False, you will need another crate in order for all of the apples to be shipped to the supermarkets.
B. True, this will hold all of the apples with some extra space left in the last crate.
C. True, 2,903 divided by 30 is 96.76666666666667. Meaning that one of them won't have exactly 30 apples.
D. False, you divide 2,903 by 30.
