The per capita consumption (in pounds) of all poultry in a country is approximated by the function C(x) = 2.49x +93.19, where x is the number of years since 2001. Find and interpret C(1), and
estimate the per capita consumption of all poultry in the country in 2010.
a. Find and interpret C(1).
The value at intercept C(1) is 95.68 pounds
The estimated per capita consumption in the year 2010 will be 115.6 pounds
Part a:
Per capita consumption of all the poultry in a country is given by the function C(x) = 2.49x + 93.19
Finding intercept C(1):
For C(1) the value of x will be 1
C(1) = 2.49(1) + 93.19
C(1) = 95.68
Hence, the value at intercept C(1) is 95.68 pounds
Part b:
Finding the per capita consumption in the year 2010:
where x will be 9, as the time period from 2001 to 2010 is 9 years
C(2010) = 2.49(9) +93.19
= 22.41 + 93.19
= 115.6
Hence, the estimated per capita consumption of all the poultry in the country will be 115.6 pounds in the year 2010

On a coordinate plane, a function has four connecting lines. The first line goes from (0, 0) to (2,2), the second line goes from (2, 2) to (3, 1), the third line goes from (3, 1) to (5, 3), and the fourth line is horizontal to the x-axis at 3. This graph shows a portion of an even function. Use the graph to complete the table of values. x f(x) −1 −3 −5 −6
Considering that the function is even, the numeric values are given as follows:
x = -1, f(x) = 1.x = -3, f(x) = 1.x = -5, f(x) = 3.x = -6, f(x) = 3.What are even and odd functions?In even functions, we have that f(x) = f(-x) for all values of x.In odd functions, we have that f(-x) = -f(x) for all values of x.If none of the above statements are true, the function is neither.In this problem, we have that the function is even, hence:
The first line goes through points (0,0) and (2,2), hence y = x, then when x = 1, y = 1 and when x = -1, y = 1, because f(x) = f(-x).f(3) = 1, hence, f(-3) = 1.f(5) = 3, hence f(-5) = 3.Due to the horizontal line, f(6) = 3, hence f(-6) = 3.More can be learned about even functions at https://brainly.com/question/3964641

Given the dimensions of the shape, the length of PR can be found to be 19.8 units.
How to find the length of PR?The given triangle is an equilateral triangle which means that all the sides are equal.
That then means that:
PR = QR
So we can solve as:
2n + 9 = 7n - 18
Solving for n gives:
7n - 2n = 18 + 9
5n = 27
n = 5.4
The length of PR is therefore:

You can spend at most $48 at the fair. Game tickets cost $1 each, and ride
tickets cost $3 each. You want to buy at least 4 game tickets and more than 3
ride tickets. Which system of linear inequalities represents the situation?
Answer:b i think
but im not sure
Step-by-step explanation:
According to the question, equation 3r + g ≤ 48 where r > 3 and g ≥ 4 represents the given situation.
What are linear inequalities?When two mathematical expressions or two numbers are compared in an unequal way, it is known as an inequality in mathematics. Inequalities can generally be classified as either algebraic or numerical or as a combination of the two. When a polynomial of degree 1 is compared to another algebraic expression of a degree less than or equal to 1, this is an example of a linear inequality, which is an inequality involving at least one linear algebraic expression.
Given, A maximum of $48 can be spent during the show. Each game ticket (g) costs $1, while each ride ticket (r) costs $3. At least 4 game tickets and more than 3 transportation tickets are what you want to purchase. From that, we can drive that sum of 3 times of ride ticket and game ticket cost should be at least greater than 48. Hence,
$3 * ride cost + $1 * game cost ≤ 48
Therefore, The above circumstance is represented by the equation
3r + g ≤ 48, where r > 3 and g ≥ 4.

Determine whether each function is an example of exponential growth or decay. Then find the y -intercept.
y=0.6(1/10)x
The function y = 0.6 × ( 1/10)ˣ is a form of exponential decay and the value of y-intercept is 0.6.
The term "exponential decay" refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)ˣ, where x is the amount of time that has passed, a is the initial amount, b is the decay factor, and y is the final amount.
Consider the function,
y = 0.6 × ( 1/10)ˣ
This equation is a form of exponential decay because the number being raised in the power is a fraction, and whenever a fraction is raised to a positive power, the result decreases.
In order to determine the y-intercept of the function, we substitute the value of x as zero and find the value of y. Whenever a number is raised to zero power, the answer is always one.
Therefore,
y = 0.6 ( 1/10)ˣ
y = 0.6 × ( 1/10 )⁰

A piece of ribbon of length 1m 10cm was cut off from a length 5m. What length remained?.
The length of ribbon that remained is 3m and 90 cm which is calculated by subtracting the cut length from the total length of the ribbon.
An arithmetic operation called subtraction simulates the process of removing items from a collection.
Subtraction can mean eliminating or lowering physical and abstract quantities utilizing a variety of things, such as negative integers, fractions, irrational numbers, vectors, decimals, functions, and matrices, however it is typically linked with natural numbers in mathematics.
The total length of the ribbon is is 5 meters or 500 centimeters. The length of the piece of ribbon that was cut is 1 m 10 cm=110 cm.
Length of the ribbon that remained is calculated by subtracting the total length form the cut off length 500-110 = 390 centimeters.

3: Recycling Center B processes aluminum faster; its rate is about 120 pounds per hour.
4: Recycling Center B processes aluminum faster; its rate is about 240 pounds per hour.
We need to know about unitary method to solve the given question. Option () is correct, Recycling Center A processes aluminium faster; Recycling Center B's rate is about 24 pounds per hour.
Unitary method is a method to find out the value for a single quantity and then derive the value for the asked quantity. Here is this question we know Center A processes aluminium at a rate of 100 pounds per hour and center B processes 2 tons per week, we need to know who processes aluminium faster. To find the answer we need to first find how much aluminium center B processes per hour, to find that we need to use unitary method.
1 ton=2000 pounds
so, 2tons=2x2000=4000 pounds
Thus Center B processes 4000 pounds per week
A day has 24 hours, a week has 7 days, we know that the centers operate all day every day so number of hours in a week is
7x24=168 hours
Center B processes 4000 pounds in 168 hours
Center B processes 4000/168 pounds in one hour
Center B processes about 24 pounds in one hour
Therefore, we can see that Center A processes aluminium faster and Center B's rate is about 24 pounds per hour, thus option (2) is right.
