Answer:
The triangle has sides lengths 28, 56, 48
Step-by-step explanation:
Let x = the shortest side
So then the longest side will be 2x, because the question said that "the longest side... is twice the length of the shortest side" Then the third side would be x + 20.
The perimeter was given so add all the sides and set it equal to 132.
x + 2x + x + 20 = 132
Combine like terms.
4x + 20 = 132
Subtract 20
4x = 112
Divide by 4.
x = 28
Then use x = 28 to find the lengths of all the sides.
Shortest Side:
x = 28
Longest Side:
2x
= 2(28)
= 56
Third Side:
x + 20
= 28 + 20
= 48

Choose the triangle in which angle 2 is not an exterior angle.
help me...new freinds?
Answer:
The third triangle
Step-by-step explanation:
The Exterior Angle is the angle a side of a shape and a line extended from the side next to it.
So for example, the first picture shows an exterior angle because a line was extended and it forms an angle with the triangle's side.
The second picture is still an exterior angle because the angle is formed with an extended line and the triangle's side.
The third photo shows an angle formed between a random line and the triangle's side. This is not an exterior angle because the angle is not formed with any side's extension.
The fourth photo is an exterior angle because it shows the angle being formed with an extension of a line from the triangle and a side of the triangle.
Hope this helps! Feel free to ask any questions! :)

Find the equation of locus of a point which moves so that
1. Its distance from X-axis is always 4 units.
Answer:
Given,
Moving point =P(x,y)
Fixed point = Q(x,0)
PQ = 4 units
now,
PQ² = (x-x)² + (y-0)²
or, 4² = 0² + y²
or, 16 = y²
or, √16 = y
∴ y = ±4
The equation of the locus of the moving point that maintains a distance of 4 units from the X-axis is y = ±4, representing two parallel horizontal lines.
To find the equation of the locus of a point that always maintains a distance of 4 units from the X-axis, let's analyze the given information.
Let P(x, y) be the moving point and Q(x, 0) be the fixed point on the X-axis. The distance between P and Q is denoted by PQ. According to the problem, PQ is always 4 units.
Using the distance formula, we have:
PQ² = (x - x)² + (y - 0)²
Since the x-coordinate of both P and Q is the same (x - x = 0), the equation simplifies to:
PQ² = y²
Substituting the value of PQ as 4 units:
4² = y²
16 = y²
Taking the square root of both sides:
\(\sqrt{16 } = \sqrt{y^2}\)
±4 = y
Therefore, the y-coordinate of the moving point P can be either positive or negative 4, giving us two possible solutions for the y-coordinate.
Hence, the locus of the moving point P that maintains a distance of 4 units from the X-axis is given by the equation:
y = ±4
This equation represents two horizontal lines parallel to the X-axis, with y-coordinates at +4 and -4. Any point (x, y) on these lines will always be at a constant distance of 4 units from the X-axis.

Express the confidence interval 0.039 < p < 0.479 in the form p± E. A. 0.22 ±0.5 B. 0.259 ±0.5 C. 0.259 ±0.44
D. 0.259 ±0.22
Answer:
Step-by-step explanation:
To express the confidence interval 0.039 < p < 0.479 in the form p ± E, we need to find the midpoint of the interval and half of the width.
The midpoint of the interval is the average of the lower and upper bounds:
Midpoint = (0.039 + 0.479) / 2 = 0.259
The width of the interval is the difference between the upper and lower bounds:
Width = 0.479 - 0.039 = 0.44
Half of the width is obtained by dividing the width by 2:
Half Width = 0.44 / 2 = 0.22
Therefore, the confidence interval 0.039 < p < 0.479 can be expressed as:
p ± E = 0.259 ± 0.22
So, the correct option is:
D. 0.259 ± 0.22

The image point of A after a translation right 4 units and up 4 units is the point B (3,8). Determine the coordinates of the pre image point A
The coordinate of the image point A (-1, 4).
What is translation?In mathematics, a translation is an up, down, left, or right movement of shapes. Because the translated shapes appear to be identically similar in size to the original ones, they are congruent with one another.
The Rule of Translation of points is given by (x, y) → (x ± h, y ± k)
where the horizontal and vertical shiftings are h units and k units, respectively.
Given that
The image point of A after a translation right 4 units and up 4 units is the point B
Let A(x, y) be the point that translated to right 4 units and up 4 units
According to the given formula
(x, y) → (x ± h, y ± k)
Since the point is translated to right and up
=> (x, y) → (x + h, y + k)
=> (x, y) → (x + 4, y + 4)
From the given data the final point is B(3, 8)
=> (x + 4, y + 4) = (3, 8)
=> x + 4 = 3 and y + 4 = 8
=> x + 4 = 3
=> x = 3 - 4 = -1
=> x = -`1
=> y + 4 = 8
=> y = 8 - 4
=> y = 4
Therefore,

find f ( a ) , f ( a h ) , and the difference quotient for the function given below, where h ≠ 0 . f ( x ) = 8 x − 9
The difference quotient for the function is 8.
The function is given by:
f ( x ) = 8 x − 9, where h ≠ 0
To find f(a), substitute a for x in the function. So we have:
f ( a ) = 8 a − 9
To find f(a + h), substitute a + h for x in the function. So we have:
f ( a + h ) = 8 ( a + h ) − 9
The difference quotient can be found using the formula:
(f(a + h) - f(a))/h
Substituting the values found above, we have:
(8 ( a + h ) − 9 - (8 a − 9))/h
Expanding the brackets and simplifying, we have:
((8a + 8h) - 9 - 8a + 9)/h

Sin0=20/29 find tan 0
Answer:
Step-by-step explanation:
here opposite =20, hypotenuse=29
to find adjacent use formula
a^2+b^2=c^2
20^2+b^2=29^2
400+b^2=841
b^2=841-400
b=\(\sqrt{441\\}\)
b=21
tan theta=opposite/adjacent
=20/21
therefore tan theta =20/21
Answer:
D. tanθ = 20/21
Step-by-step explanation:
Remember that sinθ = opposite/hypotenuse. In this case, since sinθ = 20/29, we are going to say that opposite = 20 and hypotenuse = 29.
To solve for the adjacent side, use the Pythagorean theorem, a^2 + b^2 = c^2.
When you plug in your values and solve for the other leg, you'll get 21.
Now that we know that the adjacent side/other leg is equal to 21, we can find tanθ, since it's equal to opposite/adjacent.
Opposite = 20
Adjacent = 21
tanθ = 20/21

shaunta is developing a recursive formula to represent an arithmetic sequence in which 5 is added to each term to determine each successive term. which formula could represent her sequence? f(n 1)
The recursive formula f(n+1) = f(n) + 5, you can find any term in the sequence by starting with the initial term and adding 5 repeatedly.
To represent the given arithmetic sequence where 5 is added to each term to determine each successive term, the recursive formula can be expressed as: f(n+1) = f(n) + 5
In this formula, f(n+1) represents the next term in the sequence, while f(n) represents the current term. By adding 5 to each term, we can generate the next term in the sequence.
For example, let's assume the first term of the sequence is f(1) = a. Then, the second term would be f(2) = a + 5. The third term would be f(3) = (a + 5) + 5 = a + 10, and so on.
By using the recursive formula f(n+1) = f(n) + 5, you can find any term in the sequence by starting with the initial term and adding 5 repeatedly.

Find the volume of the following solids.
The base of the solid is the region between the curve y=2√sin x and the interval [0,π] on the x-axis. The cross-sections perpendicular to the x-axis are
a. equilateral triangles with bases running from the x-axis to the curve.
b. squares with bases running from the x-axis to the curve.
To find the volume of the solid with equilateral triangular cross-sections, we need to integrate the area of each equilateral triangle over the interval [0,π]. The area of an equilateral triangle with side length s is given by (s^2√3)/4. Since the triangles have bases running from the x-axis to the curve y=2√sin x, their side lengths will be 2√sin x. Therefore, the volume is given by the integral:
V = ∫[0,π] (2√sin x)^2√3/4 dx
Simplifying, we get:
V = √3∫[0,π] sin x dx
Using the substitution u = cos x, we get:
V = √3∫[-1,1] √(1 - u^2) du
Using the formula for the integral of the half-circle, we get:
V = (√3/2)π
Therefore, the volume of the solid is (√3/2)π.
To find the volume of the solid with square cross-sections, we need to integrate the area of each square over the interval [0,π]. Since the squares have bases running from the x-axis to the curve y=2√sin x, their side lengths will be 2√sin x.
Therefore, the volume is given by the integral:
V = ∫[0,π] (2√sin x)^2 dx
Simplifying, we get:
V = 4∫[0,π] sin x dx
Using the identity ∫sin x dx = -cos x + C, we get:
V = -4cos x ∣[0,π]
Since cos π = -1 and cos 0 = 1, we get:
V = -4(-1 - 1) = 8
Therefore, the volume of the solid is 8.

Parallel lines are always coplanar. Perpendicular lines are always coplanar and, Distance around an unmarked circle can never be measured.
What are parallel and perpendicular lines?Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.
1. Parallel lines are always coplanar.
When two lines are parallel to each other it means that the two lines will never intersect each other and their plane is also the same.
2. Perpendicular lines are always coplanar.
From the definition that two lines will be perpendicular to each other their angle should be 90 degrees or they should intersect at 90 degrees angle to each other.
3. Distance around an unmarked circle can never be measured.
We need to have a marked circle to measure the distance. So, the distance from the centre of the circle to one point of it is the radius. Moreover, the distance between two points of the circle taking a line passing through the centre is the diameter of the circle.
