The Sugar Sweet Company is going to transport its sugar to market. It will cost $3500 to rent trucks plus $225 for each ton of sugar transported. The total cost, C (in dollars), for transporting N tons is given by the following function. C(n)=3500+225n)
Answers
Answer:to answer this question you have to look at what the relationship is between tones of sugar and the equation C(n) = 6,500 + 225n. The question gave you a hint in parenthesis in the form of (n) tons. This statement means that the amount of sugar is n so for question 1 the 13 tons is the n value.
Q1:
C(13) = 6,500 + 225*13
C(13) = 6,500 + 2,925
C(13) = 9,425
so what does the 9,425 mean? This is the cost to transport 13 tons of sugar.
Q2:
so this part n is unknown and we are given the C(n) number.
11,450 = 6,500 + 225n
subtract the 6500 from both sides
11,450 - 6,500 = 225n
evaluate
4,950 = 225n
I don't like the n on the right side so I am going to rewrite the equation
225n = 4,950
divide by 225
n = 4,950/225
evaluate
n = 22
So this result means that the company would transport 22 tones of sugar.

Find the value of k in the data set so that f(x) is a linear function.
x = {-7, -2, 2, 5}
f(x) = {-15, k, 3, 9}
Answers
In order for f(x) to be a linear function, determine the value of k in the data set.
x = {-7, -2, 2, 5}
f(x) = {-15, k, 3, 9}
The value of k is {-5}.
Given that to find the value of k in the data set such that the data set represents a linear function.
Linear Function is a straight line on the coordinate plane is represented by a linear function. The formula for a linear function is f(x) = mx + b, where m and b are real values.
Here, f(x) or y is the dependent variable, m is a slope of the line, x is the independent variable and b is the y-intercept.
Here,(x,f(x)) are {(-7,-15),(-2,k),(2,3),(5,9)}
The slope of the function,
(x, f(x)) = (2,3) and (5,9)
Slope formula is m=[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
Slope m= [tex]\frac{9-3 }{5-2}[/tex]
Slope m=[tex]\frac{6}{3}[/tex]
Slope m=2.
Using the point slope form, determine the linear function's equation.
[tex]y-y_{1} =m(x-x_{1})[/tex]
Here, [tex](x_{1},y_{1})=(-7,-15)[/tex] and m=2
We get
y + 15 = 2 (x + 7)
y = 2x - 1
Now at x = -2 and f(x) = k
k = 2(-2) - 1
k = -4-1
k=-5
Therefore, the value of k is -5.

Answers
The distance between Earth and Mars in the standard form is 43, 500, 000 miles.
The correct answer is an option (C)
In this question we have been given the distance between Earth and Mars.
The distance between Earth and Mars is approximately 4.35 × 10^7 miles.
We need to write above distance between Earth and Mars in the standard form.
So, we get an expression,
4.35 × 10^7 miles
= 435 × 10^5 miles
= 435 × 100, 000 miles
= 43, 500, 000 miles
Therefore, the distance between Earth and Mars in the standard form is 43, 500, 000 miles.

pansy measured the height of a window frame as 5.12 feet, but the actual height was 6 feet. what is the percentage of error in pansy's measurement?
Answers
The percentage of error in Pansy's measurement is 14.67%
In the given statement is :
Pansy measured the height of a window frame as 5.12 feet, but the actual height was 6 feet.
We know that
Percentage error can be calculated using the formula: (what was measured - the actual measurement) / actual measurement × 100%.
Thus:
The height that was measured = 5.12 feet
Actual measurement of the height = 6 feet
Percentage error = (6 - 5.12) / 6 × 100

how to Solve 5 |2x - 1 +20=3
Answers
the correct value for x is -1.2, 2.2
Given 5 | 2x - 1 | + 20 = 3
Modulus of a number
The modulus or absolute value, of a number, denoted |x+y| is calculated as
|x + y | =1
x + y = ±1
We need to solve for the value of x
5 | 2x - 1 | = 3 - 20
5 | 2x - 1 | = -17
| 2x - 1 | = - 17 / 5
| 2x - 1 | = - 3.4
2x - 1 = ± (- 3.4)
2x - 1 = -3.4 2x -1 = 3.4
2x = - 3.4 + 1 2x = 3.4 + 1

Answers
The statement "the difference between cross-sectional and time series data is whether the data is evaluated at a single point in time or multiple factors in time" is true.
The distinction between cross-sectional data and time-series data is that time-series data takes into account the identical variables over a period of time, whereas cross-sectional data makes use of specific records for a specific factor in time.
A data set may be both time series and cross sectional.
When the records of go sectional records is regressed, the defined and explanatory variables are all related to the identical single length or point in time.
Time-series and cross-section (TSCS) data collectively are normally analyzed in political technology and associated disciplines.

From the arc length given radius yielded is 22.91 cm.
What is the arc length?
The arc period estimate for a circle equals the radius of the circle. whilst r is in radians, the system for arc length may be written as arc length = r. Arc period = (/180) r, wherein r is the radius and L is the length of an arc.The radius is inversely proportional to the arc period.The length of an arc is the space between its ends measured along a circle (in units like inches or centimeters).The primary angle:

if the rate of inflation is 3.9% per year, the future price pt (in dollars) of a certain item can be modeled by the following exponential function, where t is the number of years from today.
Answers
The current price of the item = 400 dollars
The price in 8 years from today = 543.23 dollars
Given the rate of inflation = 3.9%
The exponential function modelling the future price, p(t) in t years for a certain item is, [tex]p(t)=400(1.039^t)[/tex]
We have to find the current price of the item. This is given by substituting t = 0 in p(t).
That is, p(0) = 400 x 1 = 400 dollars
Therefore current price = 400 dollars
To find the price of the product in 8 years, substitute t = 8 in p(t).
That is, p(8) = [tex]400(1.039^8)[/tex] = 543.23 dollars

In the expression given; the modulus of -6 written as
|-6|=-(-6) this is because the value is less than zero
The modulus of 2 written as; |2|=2 this is because the value is greater than zero. and;
|The modulus of -14 written as; |-14|= -(-14) since the value is less than zero.
Hence, we can rewrite the expression as;
we deal with multiplication first following the rules of BODMAS
