Write functions for each of the following transformations using function notation. Choose a different letter to represent each function. For example, you can use R to represent rotations. Assume that a positive rotation occurs in the counterclockwise direction.
translation of a units to the right and b units up
reflection across the y-axis
reflection across the x-axis
rotation of 90 degrees counterclockwise about the origin, point O
rotation of 180 degrees counterclockwise about the origin, point O
rotation of 270 degrees counterclockwise about the origin, point O
please use this format:
T(x, y) = (x + 6, y)
T<6, 0>(x, y) = (x + 6, y)
T6, 0(x, y) = (x + 6, y)
Answers
Answer:
[tex](a)\ T_{a,b} =(x +a,y+b)[/tex]
[tex](b)\ F_{y\ axis} = (-x,y)[/tex]
[tex](c)\ F_{x\ axis} = (x,-y)[/tex]
[tex](d)\ R_{o,90^o} = (-y,x)[/tex]
[tex](e)\ R_{o,180^o} = (-x,-y)[/tex]
[tex](f)\ R_{o,270^o} = (y,-x)[/tex]
Step-by-step explanation:
Solving (a): Translate a units right, b units up
When a function is translated a units right, the number of units will be added to the x coordinate
When a function is translated b units up, the number of units will be added to the y coordinate.
So, we have:
[tex]T_{a,b} =(x +a,y+b)[/tex]
Solving (b): Reflect across y-axis
When a function is translated across the y-axis, the x coordinate gets negated.
So, we have:
[tex]F_{y\ axis} = (-x,y)[/tex]
Solving (c): Reflect across x-axis
When a function is translated across the x-axis, the y coordinate gets negated.
So, we have:
[tex]F_{x\ axis} = (x,-y)[/tex]
Solving (d): 90 degrees rotation counterclockwise
When a function is rotated 90 degrees counterclockwise, the y-coordinates gets negated and then swapped with the x-coordinate.
So, we have:
[tex]R_{o,90^o} = (-y,x)[/tex]
Solving (e): 180 degrees rotation counterclockwise
When a function is rotated 180 degrees counterclockwise, the coordinates are negated.
So, we have:
[tex]R_{o,180^o} = (-x,-y)[/tex]
Solving (f): 270 degrees rotation counterclockwise
When a function is rotated 270 degrees counterclockwise, the x-coordinates gets negated and then swapped with the y-coordinate.
So, we have:
[tex]R_{o,270^o} = (y,-x)[/tex]

Is this sequence arithmetic or geometric? How do you know?
Answers
Answer:
[tex]\sum_{n = 1} 2*(-5)^{n-1}[/tex]
Step-by-step explanation:
An arithmetic sequence is of the form:
[tex]A_n = A_{n-1} + d[/tex]
While a geometric sequence is of the form:
[tex]A_n = A_{n-1}*r[/tex]
notice that first, we have a change of sign in our sequence, so we already can discard the arithmetic sequence.
In fact, the pattern is kinda easy to see.
The first term is:
A₁ = 2
the second term is:
A₂ = -10
notice that:
A₂/A₍ = r = -10/2 = -5
The third term is:
A₃ = 50
the quotient between the third term and the second term is:
A₃/A₂ = 50/-10 = -5
Whit this we can already conclude that the n-th term of our sequence will be:
[tex]A_n = A_{n-1}*(-5)[/tex]
Then the summation will be something like:
[tex]\sum_{n = 1} A_n = A_1 + A_2 + A_3 + ... = 2 - 10 + 50 - ...[/tex]
We can write:
[tex]A_n = A_{n-1}*(-5) = (A_{n-2}*(-5))*(-5)) = A_1*(-5)^{n-1} = 2*(-5)^{n-1}[/tex]
Then the summation is just:
[tex]\sum_{n = 1} 2*(-5)^{n-1}[/tex]

Answer:
down by 1 unit and left by 4 units
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Then
g(x) = (x + 4)² - 1
is f(x) shifted down by 1 unit and shifted left by 4 units

Answers
9514 1404 393
Answer:
160,000 m²16 haStep-by-step explanation:
The side length of a square is 1/4 of the perimeter, so the side length of the square orchard is (1600 m)/4 = 400 m.
The area of a square is the square of the side length, so the area of the orchard is (400 m)² = 160,000 m².
A hectare is 10,000 m², so the area of the orchard in hectares is ...
16·(10,000 m²) = 16 ha

A scientist has acid solutions with concentrations of 4% and 15%. He wants to mix some of each solution to get 44 milliliters of solution with a 12% concentration. How many milliliters of each solution does he need to mix together?
Answers
Let x and y be the amounts (in mL) of the 4% and 15% solutions, respectively, that the scientist needs to use.
He wants to end up with a 44 mL solution, so
x + y = 44 mL
Each milliliter of 4% solution contains 0.04 mL of acid, while each mL of 15% contains 0.15 mL of acid. The resulting solution should have a concentration of 12%, so that each mL of it contains 0.12 mL of acid. Then the solution will contain
0.04x + 0.15y = 0.12 × (44 mL) = 5.28 mL
of acid.
Solve for x and y. In the first equation, we have y = 44 mL - x, and substituting into the second equation gives
0.04x + 0.15 (44 mL - x) = 5.28 mL
0.04x + 6.6 mL - 0.15x = 5.28 mL
1.32 mL = 0.19x
x ≈ 6.95 mL
==> y ≈ 37.05 mL
3.3 A circle has a radius of 12cm. An angle of 3.2 radians is subtended at the centre by an arc. Calculate the length of the arc. (3)
Answers
Answer:
S = 38.4 centimeters.
Step-by-step explanation:
Given the following data;
Radius, r = 12 cmAngle = 3.2 radsTo find the length of the arc of a circle;
A full circle measures an angle of 360 degrees.
π = 180°
So; Angle, A = 360° = 2π
Therefore, a full circle is equal to 2π in terms of radians (rads).
Also, the circumference (the length of an arc) of a circle is equal to 2πr or Ar.
Mathematically, the length of the arc of a circle is given by the formula;
S = rA
Where;
S is the length of the arc.A is the angle measured in radians.Substituting into the formula, we have;
S = 12 * 3.2
S = 38.4 centimeters.

A population has a mean of 300 and a standard deviation of 18. A sample of 144 observations will be taken. The probability that the sample mean will be between 297 to 303 is:_______
a. 0.9545.
b. 0.9332.
c. 0.0668.
d. 0.4332.
Answers
Answer:
0.9545
Step-by-step explanation:
Given that :
Mean = 300
Standard deviation, σ = 18
Sample size, n = 144
Zscore = (x - mean) ÷ σ/√n
At score, x = 297
Zscore = (297 - 300) / (18/12) = - 2
P(Z< - 2) = 0.02275
At score, x = 303
Zscore = (303 - 300) / (18/12) = 2
P(Z< 2) = 0.97725
P(Z < 2) - P(Z < - 2) = 0.97725 - 0.02275 = 0.9545
The probability that the sample mean will be between 297 to 303 is 0.9545.
We have given that ,A population has a mean of 300 and a standard deviation of 18. A sample of 144 observations will be taken.
Mean = 300
Standard deviation, σ = 18
Sample size, n = 144
We have to find the probability that the sample mean will be between 297 to 303
Therefore we use the formula of Z score.
What is the formula of Z score?[tex]Zscore = \frac{ (x - mean)}{\sigma/\sqrt n}[/tex]
At the score, x = 297
Zscore = (297 - 300) / (18/12) = - 2
P(Z< - 2) = 0.02275
At score, x = 303
Zscore = (303 - 300) / (18/12) = 2
P(Z< 2) = 0.97725
Therefore we get,
P(Z < 2) - P(Z < - 2) = 0.97725 - 0.02275 = 0.9545
Therefore,the probability that the sample mean will be between 297 to 303 is 0.9545.

The mean of the data set 21.8, 23.3, 18.9, 22.9, 19.4, 23.7, 21.8, 22.8, 20.9, 21.1, 21.5, 22.9, 18.8, 22.6, 22.3, 20.8, 20.3, 19.1, 23.3, 18.8, 19.8, 24.2 is 21.41 the asnwer is 21.41.
What is mean?It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
We have a data set:
{21.8, 23.3, 18.9, 22.9, 19.4, 23.7, 21.8, 22.8, 20.9, 21.1, 21.5, 22.9, 18.8, 22.6, 22.3, 20.8, 20.3, 19.1, 23.3, 18.8, 19.8, 24.2}
As we know from the definition of the mean:
The mean can be calculated using the formula:
Mean = sum of the data set/number of the data in the data set
Mean = 471/22
Mean = 21.409 ≈ 21.41
Thus, the mean of the data set 21.8, 23.3, 18.9, 22.9, 19.4, 23.7, 21.8, 22.8, 20.9, 21.1, 21.5, 22.9, 18.8, 22.6, 22.3, 20.8, 20.3, 19.1, 23.3, 18.8, 19.8, 24.2 is 21.41 the asnwer is 21.41.
