f+an=g Solve for 'f'.
Answer:
f = g - an
Step-by-step explanation:
f + an = g
To isolate f, we need to do inverse (opposite) operation for an.
The opposite of +an is -an
f = g - an

3) The time taken is 1.2 s
4) The time taken is 81 s
5) The time taken is 5.7 s
What is the time taken for the free fall?Using the equation of kinematics under gravity we knw that;
h = ut + 1/2 gt^2
h = height from which it fell
u = initial velocity
g = acceleration due to gravity
t = time taken
Given the fact that the objects were dropped from a height u = 0 m/s
h = 1/2 gt^2
t = √2h/g

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}
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.

find the radius r of the circle if an arc of length 20 cm on the circle subtends a central angle of 40°. (round your answer to two decimal places.)
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:
40°
Arc size
20 cm
Recall the arc length formula.
[tex]l=(\frac{Theta}{360} )*(2\pi r)[/tex]
Inserting the values:

true or false: the difference between cross-sectional and time series data is whether the data is evaluated at a single point in time or multiple points in time
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.
Therefore, 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.

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?
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

Applying the rule of modulus for given values, the expression will result to 20.
What is Modulus or Absolute ValuesThe modulus of a value for example |a|=a if a is greater than or equal to zero
and also
|a|=-a if a is less than zero
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
2×-(-6)-3×2+[-(-14)]
2×6-6+14
and thus adding values
12+14-6
and finally we subtract;

how to Solve 5 |2x - 1 +20=3
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
2x = - 2.4 2x = 4.4
x = - 1.2 x = 2.2

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.
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

Freida is a clothing factory manager and wants to minimize her costs in the upcoming production cycle.
Her bosses have ordered that at least 100 shirts (s) and more than 150 pairs of pants (p) must be made to
meet inventory requirements. The factory cannot produce more than 800 garments in total and at east as
many pants as shirts produced. The total garments produced must also be at least 300. Shirts cost $8 each
to manufacture and sell for $22 while pants cost $5 to make and sell for $15. The factory costs $600 to run no
matter how many garments are made. How many shirts and pants should be made in order to minimize
costs?

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)
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.

Step-by-step explanation:
a hexagon inscribed in a circle has three consecutive sides each of length 3 and three consecutive sides each of length 5. the chord of the circle that divides the hexagon into two trapezoids, one with three sides each of length 3 and the other with three sides each of length 5, has length equal to $m/n$, where $m$ and $n$ are relatively prime positive integers. find $m n$.
According to given conditions, m+n is equal to 409.
Consider the diagram below.
In the hexagon ABCDEF, let
AB = BC = CD = 3;
DE = EF = FA = 5;
Arc BAF is equal to one-third of the circle's circumference.
Hence, ∠BCF = ∠BEF = 60°;
Similarly, ∠CBE = ∠CFE = 60°;
Let the point of intersection of BE and CF be P, BE and AD be Q and CF and AD be R.
∴ Δ EFP and Δ BCP are equilateral, and so Δ PQR is also equilateral.
Also, ∠ BAD and ∠ BED subtend the same arc and so do ∠ ABE and ∠ ADE.
∴ Δ ABQ is similar to Δ EDQ
[tex]\frac{AQ}{EQ} = \frac{BQ}{DQ} = \frac{AB}{ED} = \frac{3}{5}[/tex]
Also,
[tex]\frac{\frac{AD - PQ}{2} }{PQ + 5} = \frac{3}{5}[/tex]
and [tex]\frac{3 - PQ}{\frac{AD + PQ}{2} } = \frac{3}{5}[/tex]
On solving these simultaneous equations, we get AD = 360/49
∴ m + n = 409.
