Answer:
1. This question seems to already have the answer. The radius of the circle is the distance from the center of the circle to any point on the circle.
2. $65.91
3. 36.04cm
Step-by-step explanation:
2. First, you neeed to solve for the circumference of the circle to determine how much fencing you will need. To do this, use the formula C=2πr and insert the given radius of 3.8 into the equation.
C = 2 * pi * 3.8
C = 23.88
Then, to find the total cost, multiply the circumference by the price per meter of fencing.
23.88 * 2.76 = 65.91
3. First, you have to find the total area of the circle so you can work backwards to find the diameter. To do this, since there are 12 slices, multiply the area of each slice by 12.
85 * 12 = 1020
So 1020 is the area of the circle. The formula to find the area of a circle is A = πr^2. So we need to use that equation to find the radius, so we can double it to get the diameter.
We know the area is 1020 so we set that to A.
1020 = pi(r^2)
Divide both sides by pi.
1020/pi = r^2
Then square root both sides.
sqrt(1020/pi) = r
r = 18.02
Then, since diameter is r*2, you can just multiply 18.02 * 2 to get the diameter.
d = 18.02 * 2
d = 36.04

That can be factored as
(x -1 (1/3) ) * ( x +3) * (x -4/5)
and the zeroes are located at:
x = 1.33333333... x = -3 and x = .8
Step-by-step explanation:
Answer:
\(\boxed{\sf \ \ \ f(x)=(x+3)(5x-4)(3x-4) \ \ \ }\)
Step-by-step explanation:
We need to factorise the following function
\(f(x)=15 x^3+13 x^2-80 x+48\)
-3 is a trivial solution, we can notice that f(-3)=0
so we can factorise by (x+3)
let s note a, b and c real and let s write
\(f(x)=15 x^3+13 x^2-80 x+48=(x+3)(ax^2+bx+c)\)
\((x+3)(ax^2+bx+c) = ax^3+bx^2+cx+3ax^2+3bx+3c=ax^3+(b+3a)x^2+(3b+c)x+3c\)
let s identify...
the terms in \(x^3\)
15 = a
the terms in \(x^2\)
13 = b + 3a
the terms in x
-80 = 3b+c
the constant terms
48 = 3c
so it comes, c=48/3=16, a = 15, b = 13-3*15=13-45=-32
so \(f(x)=(x+3)(15x^2-32x+16)\)
\(\Delta=32^2-4*15*16=64\)
so the roots of \((15x^2-32x+16)\) are
\(\dfrac{32-8}{15*2}=\dfrac{24}{30}=\dfrac{12}{15}=\dfrac{4}{5}\)
and
\(\dfrac{32+8}{15*2}=\dfrac{40}{30}=\dfrac{20}{15}=\dfrac{4}{3}\)
so \(f(x)=(x+3)(5x-4)(3x-4)\)
the zeros are -3, 4/5, 4/3

(b) a dy integral that represents the surface area of the solid formed when c is rotated about the (x or y)-axis
The surface area of the surface generated by rotating the curve y = x² about the y-axis, and we found that the surface area is approximately 54.33 square units.
In this case, the curve we want to rotate is y = x², and we want to rotate it about the y-axis. To use the formula above, we need to express the equation of the curve in terms of x. Therefore, we need to rewrite y = x² as x = √y.
Next, we need to find the derivative of x = √y with respect to y, which is:
dx/dy = 1/2√y
Substituting this into the formula for the surface area, we get:
Surface Area = 2π ∫[0,4] √y √(1+(1/2√y)²) dy
Simplifying the expression inside the square root, we get:
Surface Area = 2π ∫[0,4] √(y+(1/4)) dy
We can evaluate this integral using the power rule of integration, which gives:
Surface Area = 2π [2/3(y+(1/4))^(3/2)]₀⁴
Simplifying further, we get:
Surface Area = 2π [2/3(17/4)^(3/2)]
Surface Area ≈ 54.33 square units
Therefore, the surface area of the surface generated by rotating the curve y = x² about the y-axis is approximately 54.33 square units.

A square array of numbers, often positive integers, is referred to as a magic square in recreational mathematics if the sums of the numbers in each row, each column, and both main diagonals are the same.
The following values are listed in the question:
The numbers are 4, 5, 6, 14, 15, 16, 24, 25, and 26.
A 3-by-3 magic square is required.
Since the numbers are 4, 5, 6, 14, 15, 16, 24, 25, and 26.
Now the sum of all numbers is :
4 + 5 + 6 + 14 + 15 + 16 + 24 + 25 + 26 = 135
There are now 3 rows and 3 columns, thus the total number is divided by 3.
5 24 16
26 15 4
14 6 25
5 + 24 + 16 = 45
5 + 26 + 14 = 45
26 + 15 + 4 = 45
24 + 15 + 16 = 45
14 + 6 + 25 = 45
5 + 15 + 25 = 45
So, the total of each row and each column is therefore 45.

Jack was 13 years older than Priscilla. together their ages totaled 163 years . What were their ages?
Answer:
Jack is 88, Priscilla is 75.
Step-by-step explanation:
Let J represent Jack's age and let P represent Priscilla's age.
Their age totaled 163, so:
\(J+P=163\)
And we know that Jack was 13 years older than Priscilla. In other words:
\(J=13+P\)
Solve for J and P. To do so, substitute the second equation into the first:
\(13+P+P=163\)
Combine like terms:
\(2P+13=163\)
Subtract 13 from both sides:
\(2P=150\)
Divide 2 from both sides:
\(P=75\)
So, Priscilla is 75 years old right now.
Jack is 13 years older meaning that Jack is 88 years right now.

Your answer is -24.
Step-by-step explanation:
Given information.
The graph of f(x) and g(x)
Solving for
-6 * f(3) - 6 * g(-1) = ?
think of f(x) = y as x is the input and y is the output.
Input a value of x into f(x) or g(x) gets us a y value.
Looking at the graph of f(3) = -2 and the graph of g(-1) = 6
Now substitute that and solve.
-6 * -2 -6 * 6 = 12 - 36 = -24
Answer: -24
Step-by-step explanation:
We should first find the outputs to the functions f and g with inputs 3 and -1 respectively. We can do this by looking at the graph and finding the y value for each desired x value.
Thus, we can see that f(3) = -2 and g(-1) is 6.
We can replace these into the expression to get
\(-6*-2-6*6\)
We should first multiply, so we get
\(12 -36\)
\(-24\)
Hence, the answer is -24.

Answer:
m∠XYZ = 162°
Step-by-step explanation:
We can see that ∠XYZ is an exterior angle while ∠W and ∠X are the opposite interior angles.
We know that the exterior angle of triangle is equal to the sum of opposite interior angles
Given
m∠XYZ = (15x-18)°
m∠W = (5x+2)°
m∠X = (8x+4)°
Mathematically it can be written as:
m∠X+m∠W = m∠XYZ
\(8x+4+5x+2 = 15x-18\\13x+6 = 15x-18\\13x-15x = -18-6\\-2x = -24\\\frac{-2x}{-2} = \frac{-24}{-2}\\x = 12\)
Putting x=12 in m∠XYZ
\(15x-18\\=15(12)-18\\=180-18=162\)
Hence,
m∠XYZ = 162°

Which sequence of transformations was applied to the parent tangent function to create the function m(x) = 2tan(3x+4)
The function m(x) = 2tan(3x+4) is obtained by applying a sequence of transformations to the parent tangent function.
To determine the sequence of transformations, let's break down the given function:
1. Inside the tangent function, we have the expression (3x+4). This represents a horizontal compression and translation.
2. The coefficient 3 in front of x causes the function to compress horizontally by a factor of 1/3. This means that the period of the function is shortened to one-third of the parent tangent function's period.
3. The constant term 4 inside the parentheses shifts the function horizontally to the left by 4 units. So, the graph of the function is shifted to the left by 4 units.
4. Outside the tangent function, we have the coefficient 2. This represents a vertical stretch.
5. The coefficient 2 multiplies the output of the tangent function by 2, resulting in a vertical stretch. This means that the graph of the function is stretched vertically by a factor of 2.
In summary, the sequence of transformations applied to the parent tangent function to create the function m(x) = 2tan(3x+4) is a horizontal compression by a factor of 1/3, a horizontal shift to the left by 4 units, and a vertical stretch by a factor of 2.
Example:
Let's consider a point on the parent tangent function, such as (0,0), which lies on the x-axis.
After applying the transformations, the corresponding point on the function m(x) = 2tan(3x+4) would be:
(0,0) -> (0,0) (since there is no vertical shift in this case)
This example helps illustrate the effect of the transformations on the graph of the function.

Statement 5: "The Day Care and the Community Center are supplementary angles and on opposite sides of the transversal."
This is TRUE.
Statement 6: "The Bank and the Community Center are on opposite sides of the transversal and form a pair of alternate interior angles"
This is NOT TRUE.
They are on opposite side of the transversal but one the bank is an exterior angle while the community center is an interior angle.
Statement 7: "The Park and the Museum are adjacent angles and form a vertical pair of angles."
This is NOT TRUE.
They do not share the same side, so they can't be adjacent angles. They only share the same vertex, which makes them vertical angles.
Statement 8: "The Fire Station and the Community Center are consecutive interior angles lying on the same side of the transversal."
This is TRUE.
