The population of the town at any given time t can be determined using the formulas provided. For example, if the town's population at time t=5 years is desired, the population can be calculated as follows:(a) P(5) = 1600 + 70(5) = 2100 people (b) P(5) = 1600(1.09)^5 = 2266.05 people
(a) P(t) = 1600 + 70t
(b) P(t) = 1600(1.09)^t
(a) In this case, the population increases by 70 people per year, so the formula for the population as a function of time is P(t) = 1600 + 70t. This means that the population is 1600 people at time t=0 and increases by 70 people for each additional year.
(b) In this case, the population increases by 9 percent each year, so the formula for the population as a function of time is P(t) = 1600(1.09)^t. This means that the population is 1600 people at time t=0 and increases by a factor of 1.09 (9 percent) for each additional year.
The population of the town at any given time t can be determined using the formulas provided. For example, if the town's population at time t=5 years is desired, the population can be calculated as follows:
(a) P(5) = 1600 + 70(5) = 2100 people

Explain why these triangles are congruent by AAS (Angle-Angle-Side) and not ASA (Angle-Side-Angle).
The triangles are congruent by AAS (Angle-Angle-Side) and not by ASA (Angle-Side-Angle)
Properties of congruent triangles.When the corresponding length of sides or measure of the internal angles of two or more triangles are equal, then the triangles are said to be congruent. The congruency can be expressed in terms angles, sides, or the combination of sides and angles. An example is the SAA (Side-Angle-Angle) property which implies that a side that is not an included angle and other angles are congruent.
Considering triangles ABC and CDE, it can be seen that two angles are congruent and a side of both are congruent. Since the congruent side is not an included angle, then the congruent relations is AAS (Angle-Angle-Side).

The random variable X is normally distributed with mean 5 and standard deviation 25. The random variable Y is defined by Y = 2 + 4X. What are the mean and the standard deviation of Y ? The mean is 20 and the standard deviation is 102.A) The mean is 20 and the standard deviation is 50.B) The mean is 22 and the standard deviation is 102.C) The mean is 22 and the standard deviation is 100.D) The mean is 22 and the standard deviation is 50.
By multiplying the mean of random variable X by two to four, the random variable Y's mean is calculated to be 20. (5). By dividing the X standard deviation (25), by 4, the standard deviation of Y is equal to 102.
The random variable X has a mean of 5 and a standard deviation of 25. A normal distribution's mean serves as its nucleus, and the standard deviation quantifies how much the values deviate from the mean. Y = 2 + 4X is the definition of the random variable Y. By adding 2 to the mean of X (5), we can determine the mean of Y, which equals 20. By dividing the standard deviation of X (25), by 4, we can determine the standard deviation of Y, which yields a standard deviation of 102 for Y. As a result, the standard deviation is 102 and the mean of Y is 20.

Use the distributive property to write each expression as an equivalent
algebraic expression.
-2(x-4)
Answer:
the equivalent algebraic expression is -2x -8 after applying the distributive property.
Step-by-step explanation:
The distributive property states that for any real numbers a, b, and c, a(b+c) = ab + ac.
To apply the distributive property to the expression -2(x-4), we can distribute the -2 across the parenthesis, like this:
-2(x-4) = -2x + (-2)(-4)
Simplifying the last part of the expression:
-2(x-4) = -2x -8
So, the equivalent algebraic expression is -2x -8 after applying the distributive property.

Also, he must buy no less than 16 apples. If represents the number of apples purchased and y represents the number of mangos purchased, write and solve a system of inequalities graphically and determine one possible solution .
The system of inequalities is:
x + y ≥ 16
x*0.75 + y*2 ≤ 20
And its graph can be seen below, there we can see that one possible solution is (14, 2)
How to write and solve the system of inequalities?
Let's define the variables:
x = number of apples.
y = number of mangos.
Kayden needs to buy not less than 16 items, so the first inequality is:
x + y ≥ 16

x*0.75 + y*2 ≤ 20
The system of inequalities is then:
x + y ≥ 16
x*0.75 + y*2 ≤ 20
To graph it just graph the two lines and shade the region correspondent, for the first inequality shade the region above the line, for the second one shade the region below the line.

Equation:
b) How many miles is Houston from Philadelphia?
Answer:
miles
Give your answer to the nearest mile
Answer: a. The equation using the information as it is given above that can be solved to answer this question is:
distance = speed x time
Let t be the amount of time Krystal spent driving from Houston to Philadelphia.
distance = 50t + 60(46 - 25 - t)
b. To find the distance between Houston and Philadelphia, we can substitute the known values into the equation and solve for t.
distance = 50t + 60(46 - 25 - t)
distance = 50t + 60(21) - 60t
distance = 50t + 1260 - 60t
distance = -10t + 1260
To find the total distance, we can set t = 25
distance = -10(25) + 1260

find the volume v of the described solid s. the base of s is the triangular region with vertices (0, 0), (5, 0), and (0, 5). cross-sections perpendicular to the x-axis are squares.
Using the disk method, it can be concluded that the volume of the solid is 125π /3 cubic units.
Disk Method is a method used to determine the volume of a solid formed by revolving the region about the x-axis and the interval [a, b]. The volume of the solid is the integral of the area of the base times dx.
V = π ∫ Ax dx
From the question, we know that the base of the figure is a triangular region and the coordinates are (0,0), (5,0), and (0,5).
The square is perpendicular to the x-axis. Thus, we can find the side of the square, that is the straight line passing through (5,0) and (0,5) which meet the y = mx + b equation.
First, we determine the slope of the line (m).
m = (y₂ - y₁) / (x₂ - x₁)
= ( 5 - 0 ) / ( 0 - 5 )
= 5 / -5
= -1
To find b, we input the value of m into the equation for point (5,0):
y = mx + b
0 = -1*5 + b
0 = -5 + b
b = 5
So we got the side of the square:
y = mx + b
y = -x + 5
y = 5 - x
Thus the area of the square is:
A = side²
= (5 - x)²
= 25 + x² - 10x
The volume of the solid can be calculated as follows:
V = π ∫ Ax dx
= π ∫₀² (25 + x² - 10x) dx
= π (25x + 1/3x³ - 5x² |₀⁵)
= π (25*5 + 1/3*5³ - 5*5² - 0)
= π (125 + 125/3 - 125 - 0)
= 125π /3 cubic units
Thus, the volume of the solid is 125π /3 cubic units

By constructing 95% confidence intervals for each simulation, we can be 95% confident that the true proportion of wins lies within the range of each interval.
What is Confidence Intervals?A confidence interval is a set of values that, given a specific level of certainty, are likely to include a population parameter like a mean or proportion.
The interval is derived using data drawn from a sample of the population and is frequently presented as a range of values with a 95% confidence level.
The probability that the range of values contains the genuine population parameter is quantified by the confidence level.
In the case of a 95% confidence interval, for instance, it means that 95% of the intervals would contain the real population parameter if we sampled the same population more than once and calculated a confidence interval each time.

The 100th derivative of P(x) = (x+x⁵+x⁷)¹⁰(1+x²)¹¹(x³+x⁵+x⁷) will be zero.
What is a polynomial?An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given:
A polynomial,
P(x) = (x+x⁵+x⁷)¹⁰(1+x²)¹¹(x³+x⁵+x⁷).
To find the degree:
(x⁷)¹⁰(x²)¹¹(x⁷) = x⁹⁹.
The polynomial has a degree of 99.
If we think about it intuitively,
Therefore, if we were to multiply it all out,
the leading word would be x⁹⁹.
The term's first derivative is 99x⁹⁸,
followed by 99(98)x⁹⁷,
and 99(98)(97)x⁹⁶.
And finally,
the 99th derivative is 99×98×97×96×...4×3×3×2×1× (x⁰)

Read the following prompt and type your response in the space provided.
Create a real-life representation of the following multiplication problem. Explain what the result represents in the problem.
15 (2/5)=6
Answer: In a real-life representation of the multiplication problem "15 (2/5) = 6," we can imagine a bag of 15 items, each of which is 2/5 of a whole. To find out how many whole items are in the bag, we can multiply 15 (the number of items) by 2/5 (the fraction of each item that is a whole).
The result of 6 represents the number of whole items in the bag.
Step-by-step explanation:
? ÷ 2/5 = 4
Draw a diagram to represent the situation.
Given expression ?/(2/5)=4 where ?=x gives x=8/5.
what are expressions?
Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
Now,
Given expression ? ÷ 2/5 = 4
let x=?
Therefore,
x=4*2/5
x=8/5
