704 (Continuation) Find an equation for the parabola, in fac-
tored form, y a(z-p)(z-g), whose symmetry axis is parallel
to the y-axis, whose a-intercepts are -2 and 3, and whose y
intercept is 4. Why is factored form sometimes referred to as
intercept form?
The equation of the parabola in factored form is: y = 16(z - 1/2)(z - 8)
What is parabola?
A parabola is a symmetrical plane curve that is shaped like an arch. It is a quadratic function and is defined by the equation y = ax² + bx + c, where a, b, and c are constants.
Ryan's reasoning is justified because the z-intercepts of a parabola are the points where the parabola intersects the z-axis, which are the points where x = 0. Therefore, if the parabola can be expressed in the form y = a(x + 1)(x - 4), then its z-intercepts are at x = -1 and x = 4. This is because when x = -1, (x + 1) = 0 and when x = 4, (x - 4) = 0, which makes y = 0, indicating that the parabola intersects the z-axis at these two points.
To find the value of a, we need to use the given information that the y-intercept of the parabola is at (0, 2). Substituting x = 0 and y = 2 into the equation y = a(x + 1)(x - 4), we get:
2 = a(0 + 1)(0 - 4)
2 = -4a
Therefore, a = -1/2. So the equation of the parabola is y = (-1/2)(x + 1)(x - 4), in factored form.
To find the equation of the parabola in factored form y = a(z-p)(z-g), we can use the given information about its intercepts and symmetry axis. Since the symmetry axis is parallel to the y-axis, the parabola is of the form y = a(z - h)² + k, where (h, k) is the vertex. We know that the a-intercepts are -2 and 3, which means that the points (-2, 0) and (3, 0) lie on the parabola. Substituting these points into the equation, we get:
0 = a(-2 - h)² + k
0 = a(3 - h)² + k
Solving for h and k, we get:
h = 1/2
k = 4
Therefore, the vertex is at (1/2, 4), and the equation of the parabola is:
y = a(z - 1/2)² + 4
We can find the value of a by using the fact that the y-intercept is 4. Substituting z = 0 and y = 4, we get:
4 = a(0 - 1/2)² + 4
4 = a(1/4)
a = 16
Therefore, the equation of the parabola in factored form is:
y = 16(z - 1/2)(z - 8), which is sometimes referred to as intercept form because it explicitly shows the intercepts of the parabola on the z-axis.

gregs backyard is 42 feet wide how many yards and feet is that?
pls show your work. thx
Greg's backyard is 14 yards and 1 foot wide. To summarize, we can say that 42 feet is equivalent to 14 yards and 1 foot.
To convert 42 feet to yards and feet, we need to know that there are 3 feet in 1 yard. We can divide the total number of feet (42) by 3 to get the number of yards, and then take the remainder to get the remaining feet.
So, 42 feet divided by 3 feet/yard equals 14 yards. This means that Greg's backyard is 14 yards wide.
To find the remaining feet, we can multiply the decimal part of the result by 3. So, 0.333 x 3 = 0.999. Since we cannot have a fraction of a foot, we round up to the nearest whole foot, which gives us 1 foot.
Therefore, Greg's backyard is 14 yards and 1 foot wide. To summarize, we can say that 42 feet is equivalent to 14 yards and 1 foot.

Step-by-step explanation:
To find the length of the third side, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).
So, in this case, we have:
x^2 + 6^2 = 10^2
Simplifying this equation, we get:
x^2 + 36 = 100
Subtracting 36 from both sides, we get:
x^2 = 64
Taking the square root of both sides, we get:
x = 8 or x = -8
Since the length of a side of a triangle can't be negative, the length of the third side is x = 8 cm.

a tank is shaped like an upside-down square pyramid, with a base with sides that are 4 meters in length and a height of 12 meters. if water is being pumped into the pyramid at a rate of 23m3sec, at what rate is the height of the water increasing when the water is 2 meters deep? (the volume of a pyramid with height h and base area b is given by v
If a tank is shaped like an upside down square-pyramid, then the rate at which the height of water is increasing when the water is 2 m deep is 51.75 m/sec.
The tank is upside down square-pyramid, with sides as 4 meter,
Let the height of water at any time "t" be = "h",
The height of the tank is = 12 meter,
Let, the side of the base of pyramid shaped water at any time "t" be = "b",
So, b = (1/3)h ...because height of pyramid is 12 and each side is of 4, the ratio is 1/3,
The volume of water at nay time "t" is (V) = (1/3)b²h,
⇒ V = (1/3)(1/3h)²h,
⇒ V = h³/27,
Now, dv/dt = (d/dt)(h³/27),
On simplifying further,
we get,
⇒ dv/dt = (h²/9)(dh/dt),
⇒ dh/dt = (9/h²)(dv/dt),
We know that, when the water is 2 meter deep, and if water is pumped out at rate of 23 m³/sec, it means that h = 2, and dv/dt = 23,
So, dh/dt = (9/2²)(23) = 51.75 m/sec.
Therefore, the rate of change of height is 51.75 m/sec.

There is a shaded bar up to 8 above 10 to 19, up to 6 above 20 to 29, up to 2 above 30 to 39, and up to 2 above 50 to 59. There is no shaded bar above 40 to 49.
Which measure of center should the charity use to accurately represent the data? Explain your answer.
The median of 22.7 is the most accurate to use to show that they have plenty of money.
The mean of 20 is the most accurate to use to show that they need more money.
The median of 20 is the most accurate to use, since the data is skewed.
The mean of 22.7 is the most accurate to use, since the data is skewed
Answer: C. The median of 20 is the most accurate to use, since the data is skewed.
The most accurate measure of center to use in this case is the median of 20. This is because the data is skewed, with a few high-value donations (such as the two donations of 55 dollars) that pull the mean up. However, most of the donations are clustered around 10 to 20 dollars. As a result, the median, which is the middle value when the data is sorted in order, is a better representation of the "typical" donation amount.
In this case, the median is 20, which means that half of the donations were less than 20 dollars and half were more. This is a more accurate representation of the central tendency of the data than the mean of 22.7, which is influenced by the high-value donations. Therefore, the charity should use the median of 20 to accurately represent the typical donations received.

On multiplying minus sign in B equation, to eliminate the x- component in the equation.
3x +2y= -6 becomes (-3x - 2y = 6)
Then, the equation becomes,
3x - 4y= -24
-3x - 2y = 6 (+ 3x - 3x are equal and opposite becomes zero.)

Find the surface area of each triangular prism.
Also don't mind my writing on the paper
The surface area of the given triangular prism is approximately 58.26 square units.
what is triangular prism?
A triangular prism is a three-dimensional geometric shape that consists of two congruent parallel triangles as its bases and three rectangular faces that connect the corresponding sides of the two triangles.
In the given question,
To find the surface area of a triangular prism, we need to add the area of all the faces of the prism. A triangular prism has two congruent triangular bases and three rectangular lateral faces.
First, let's calculate the area of the triangular bases. We can use the formula for the area of a triangle:
Area of a triangle = (1/2) * base * height
In this case, the base of the triangle is 5 and the height is 6. To find the height, we need to use the Pythagorean theorem because we are given the slant height of the triangular prism, which is the hypotenuse of the right triangle formed by the base, the height, and the slant height. The Pythagorean theorem is:
slant height² = base² + height²
Substituting the given values, we get:
6.5² = 5² + height²
42.25 = 25 + height²
height² = 17.25
height = √17.25 ≈ 4.15
Now we can calculate the area of each triangular base:
Area of a triangular base = (1/2) * base * height
Area of each triangular base = (1/2) * 5 * 4.15
Area of each triangular base ≈ 10.38
Next, we need to calculate the area of each rectangular lateral face. The length of each lateral face is the same as the base of the triangle, which is 5, and the width is the same as the width of the prism, which is 2.5. The height of each lateral face is the same as the height of the prism, which is 6. Therefore, the area of each rectangular lateral face is:
Area of a rectangular lateral face = length * width
Area of each rectangular lateral face = 5 * 2.5
Area of each rectangular lateral face = 12.5
Finally, we can find the total surface area of the prism by adding up the areas of the two triangular bases and the three rectangular lateral faces:
Total surface area = 2 * area of a triangular base + 3 * area of a rectangular lateral face
Total surface area ≈ 20.76 + 37.5
Total surface area ≈ 58.26
Therefore, the surface area of the given triangular prism is approximately 58.26 square units.

Sara is paid semi-monthly. Her annual salary is $37,560. What is her semi-monthly to the nearest cent?
A)$1,444.62
B)$1,502.40
C)$1.565,00
D)$727.31
Step-by-step explanation:
To find Sara's semi-monthly salary, we need to divide her annual salary by the number of semi-monthly periods in a year.
Since there are 24 semi-monthly periods in a year (twice a month), we can divide her annual salary by 24 to get her semi-monthly salary:
$37,560 ÷ 24 = $1,565.00
Therefore, Sara's semi-monthly salary to the nearest cent is option C) $1,565.00.
onsider an economy with three industries: I1, I2, and I3. Consumer demand is currently
‚ 100 units from I1,
‚ 75 units from I2,
‚ 200 units from I3.
Also suppose that
‚ for every unit that I1 produces, it needs 0.5 units from I2 and 0.1 units from I3;
‚ for every unit that I2 produces, it needs 0.25 units from I1 and 0.2 units from I3;
‚ for every unit that I3 produces, it needs 0.3 units from I1 and 0.4 units from I2
Set up a system of equations
We have the following system of equations:
x₁ + 0.5x₂ + 0.1x₃ = 100
0.25x₁ + x₂ + 0.2x₃ = 75
0.3x₁ + 0.4x₂ + x₃ = 200
Define the term equation?Statement gives the equality of different mathematical expressions is called as an equation.
Let x₁, x₂, and x₃ be the outputs of I₁, I₂, and I₃, respectively. Then the total production must satisfy the following system of equations:
For I₁:
I₁ itself produces x₁ unitsIt requires 0.5 units of I₂ for every unit, so it requires 0.5x₂ unitsIt requires 0.1 units of I₃ for every unit, so it requires 0.1x₃ unitsTherefore, total demand from I₁ is x₁ + 0.5x₂ + 0.1x₃ = 100For I₂:
I₂ itself produces x₂ unitsIt requires 0.25 units of I₁ for every unit, so it requires 0.25x₁ unitsIt requires 0.2 units of I₃ for every unit , so it requires 0.2x₃ unitsTherefore, total demand from I₂ is x₂ + 0.25x₁ + 0.2x₃ = 75For I3:
I₃ itself produces x₃ unitsIt requires 0.3 units of I₁ for every unit, so it requires 0.3x₁ unitsIt requires 0.4 units of I₂ for every unit, so it requires 0.4x₂ unitsTherefore, total demand from I₃ is x₃ + 0.3x₁ + 0.4x₂ = 200Therefore, the system equations are:
x₁ + 0.5x₂ + 0.1x₃ = 100
0.25x₁ + x₂ + 0.2x₃ = 75
0.3x₁ + 0.4x₂ + x₃ = 200

Step-by-step explanation:
what is the length of AC in the graph below
The length AC of the triangle is 4.47 units.
How to find the length on a graph?The diagram on the graph is a triangle. The question wants us to find the length AC of the triangle.
To find the length AC in the triangle, we have to use distance formula as follows:
Therefore,
A = (1, 1)
C = (3, 5)
AC = √(y₂ - y₁)² + (x₂ - x₁)²
AC = √(5 - 1)² + (3 - 1)²
AC = √4² + 2²
AC = √16 + 4
AC = √20
Hence,
AC = 4.472135955
AC = 4.47 units

Rounding to the nearest tenth, the measure of UV is 7.1.
What is angle?An angle is a measure of space between two lines or planes. It is measured in degrees, using a protractor, and can range from 0 to 360. Angles can be either acute, obtuse, right, straight, reflex, or full. Acute angles are angles that measure less than 90 degrees, obtuse angles measure more than 90 degrees, right angles measure exactly 90 degrees, straight angles measure 180 degrees, reflex angles measure more than 180 degrees, and full angles measure 360 degrees.
To find the measure of UV in ∆ UVW, we will use the law of cosines. The law of cosines states that [tex]c^{2} =a^{2} +b^{2} -2ab cos C[/tex], where c is the length of the side opposite angle C, a and b are the lengths of the other two sides, and C is the angle opposite side c. In this case, side c is UV, a is UW, b is VW, and C is ∠ W.
Plugging in the given values, we get:
[tex]U^{2}V^{2}[/tex] = [tex]9^{2} + 12^{2} - 2 *9* 12 cos *35[/tex]
[tex]U^{2} V^{2}[/tex] = 81 + 83.44 – 162.08 cos 35°
[tex]U^{2} V^{2}[/tex] = 164.44 – 114.45
[tex]U^{2} V^{2}[/tex] = 49.99
Taking the square root of both sides, we get:
UV = 7.086
Rounding to the nearest tenth, the measure of UV is 7.1.

solve the system of equations
Answer:
(2, 3)
Step-by-step explanation:
9x - 7y = -3
+ -9x + 15y = 27
8y = 24 (Divide by 8 on both sides)
8 = 8
y = 3
Substitute y = 3 in any of the two equations.
9x - 7(3) = -3
9x - 21 = -3
+21 = +21 (Add 21 on both sides)
9x = 18 (Divide by 9 on both sides)
9 = 9
x = 2
The formula for the general term of 14,11,8,5,2
The formula for the general term of an arithmetic sequence is:
an = 14 - 3(n-1)
What do you mean by Arithmetic progression ?Arithmetic progression (AP) is a sequence of numbers in which each term after the first is obtained by adding a fixed constant value, called the common difference, to the preceding term. For example, 2, 4, 6, 8, 10, 12, 14... is an arithmetic progression with a common difference of 2. The formula for the nth term of an arithmetic progression is given by:
an = a1 + (n-1)d
The given sequence 14, 11, 8, 5, 2 is an arithmetic sequence with a common difference of -3.
The formula for the general term of an arithmetic sequence is:
an = a1 + (n-1)d
where:
an = the nth term of the sequence
a1 = the first term of the sequence
d = the common difference between consecutive terms
n = the position of the term we want to find
Using the values given in the sequence, we have:
a1 = 14
d = -3
To find the general term, we need to determine the value of n. Let's assume that the first term of the sequence corresponds to n = 1.
For the first term (n = 1):
a1 = 14
For the second term (n = 2):
a2 = a1 + d = 14 - 3 = 11
For the third term (n = 3):
a3 = a1 + 2d = 14 - 6 = 8
For the fourth term (n = 4):
a4 = a1 + 3d = 14 - 9 = 5
For the fifth term (n = 5):
a5 = a1 + 4d = 14 - 12 = 2
Therefore, the general term for the given sequence is:
an = 14 - 3(n-1)
or
an = 17 - 3n (Alternative form)
