Answer: 0.75
Step-by-step explanation:
We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.
We now have a triangle with the values of:
x = 4
y =3
h^2= 4^2 + 3^2
h^2 = 16 + 9
h^2 = 25
h = 5
h = 5
Tangent = opposite/adjacent
= y/x
= 3/4
= 0.75

show that the points ( 4,9,6) (-1,6,6 ) and (0,7,10) form an isosceles right angled triangle. find the perimeter of the triangle.
The perimeter of the triangle is the sum of the lengths of its sides, which is: 12.24
Explanation:
To show that the given points form an isosceles right angled triangle, we first need to find the lengths of the sides of the triangle using the distance formula.
Let the given points be A(4, 9, 6), B(-1, 6, 6), and C(0, 7, 10).
The distance between points A and B is given by:
AB = sqrt((4 - (-1))^2 + (9 - 6)^2 + (6 - 6)^2) = sqrt(5^2 + 3^2 + 0^2) = sqrt(34)
The distance between points A and C is given by:
AC = sqrt((4 - 0)^2 + (9 - 7)^2 + (6 - 10)^2) = sqrt(4^2 + 2^2 + 4^2) = 2*sqrt(6)
The distance between points B and C is given by:
BC = sqrt((-1 - 0)^2 + (6 - 7)^2 + (6 - 10)^2) = sqrt(1^2 + 1^2 + 4^2) = sqrt(18)
Now, we can see that the triangle ABC is not isosceles since all three sides have different lengths.
To check if the triangle is right-angled, we can use the Pythagorean theorem. If the square of the length of the longest side is equal to the sum of the squares of the other two sides, then the triangle is right-angled.
Here, the longest side is AC with length 2*sqrt(6), so we need to check if:
AC^2 = AB^2 + BC^2
4*6 = 34 + 18
24 = 52
This equation is not true, so the triangle ABC is not a right-angled triangle.
Therefore, the given points do not form an isosceles right angled triangle.
The perimeter of the triangle is the sum of the lengths of its sides, which is:
AB + AC + BC = sqrt(34) + 2*sqrt(6) + sqrt(18) ≈ 12.24

Find the volume of the solid whose base is a circle of radius 5, if slices made perpendicular to the base are isosceles right triangles with one leg on the base. (express numbers in exact form. Use symbolic notation and fractions where needed. )
V = ____
The solid has a 62.5 cubic unit volume. Finding the volume of a solid with a circular base of radius 5 units is the task at hand.
The following formula can be used to determine how much of the magical potion is left after a specific period of time:
Let h represent the solid's height. The volume can therefore be stated as follows:
V = (12.5 dh from 0 to h)
Combining, we obtain:
V = 12.5h
The height of the solid is equal to the radius of the circle, which is 5 units, because the slices are perpendicular to the base. Therefore:
V=12.5h=12.5(5)=62.50 cubic metres

Consider the line 3x+8y=1what is the slope of a line parallel to this line?what is the slope of a line perpendicular to this line?
To find the slope of the line given, we write the equation in slope-intercept form:
\(y=mx+b\)For the equation,
\(3x+8y=1\)subtracting 3x from both sides gives
\(8y=1-3x\)Finally, dividing both sides by 8 gives
\(y=\frac{1-3x}{8}\)which can be rearranged and written as
\(y=-\frac{3}{8}x+\frac{1}{8}\)Hence, the slope of the line parallel to the given line is -3/8.
To find the slope of the perpendicular line, we have to remember that
\(m_{\perp}=-\frac{1}{m}\)Since m = -3/8, the above gives
\(m_{\perp}=-\frac{1}{(-\frac{3}{8})}\)Simplifying the above gives
\(m_{\perp}=\frac{8}{3}\)Hence, the slope of the perpendicular line is 8/3.
two partners divide a profit of $2,000 so that's a difference between the two amounts is half of their average. what is the ratio of the larger to the smaller amount?
Answer:
5/3
Step-by-step explanation:
The partners have a total profit of $2000. Since there are only 2 partners, then the average profit each one makes is $2000/2 = $1000.
The difference between the 2 amounts is half of the average, so it is $1000/2 = $500.
One amount is x.
The other amount is x + 500
The sum is 2000
x + x + 500 = 2000
2x + 500 = 2000
2x = 1500
x = 750
x + 500 = 750 + 500 = 1250
The partners had profit of $1250 and $750.
The ratio is 1250/750 = 125/75 = 5/3
Answer: 5/3
The ratio of the larger to the smaller amount will be 5 : 3
What are ratios?
A ratio says how much of one thing there is compared to another thing. We can write the ratio as -
x : y
{x/y} = k
x = ky
[k] is called the scale factor.
Given is that two partners divide a profit of $2,000 so that's a difference between the two amounts is half of their average.
Assume that the amount with partner [1] is $[x] and with partner [2] is $[y]
. So, we can write according to the question as -
x + y = 2000 ......Eq [1]
x - y = {1/2 x (x + y)/2} ......Eq [2]
Now -
x - y = {1/2 x (2000/2)}
x - y = {1/2 x 1000}
x - y = 500
x = 500 + y
So, we can write the equation [1] as -
x + y = 2000
500 + y + y = 2000
2y = 1500
y = 750
So, [x] will be equivalent to -
x = 2000 - 750
x = 1250
The ratio of the larger to the smaller amount will be -
x/y = 1250/750 = 250/150 = 50/30 = 5/3
Therefore, the ratio of the larger to the smaller amount will be 5 : 3.

M
Oy--x-3
О У - 3x + 21
Oy - 3x +33
Answer:
y = (-1/3)x + 3.
Step-by-step explanation:
To find the equation of a line perpendicular to a given line, we need to take the negative reciprocal of the slope of the given line.
The slope of the given line Y=3x-5 is 3. Therefore, the slope of a line perpendicular to this line would be -1/3.
Now, using the point-slope form of a line, we can write the equation of the line passing through (-9,6) and having a slope of -1/3:
y - 6 = (-1/3)(x - (-9))
Simplifying:
y - 6 = (-1/3)x - 3
y = (-1/3)x + 3
Therefore, the equation of the line that passes through (-9,6) and is perpendicular to the line Y=3x-5 is y = (-1/3)x + 3.

How do you find the moment of inertia of multiple bodies?
Answer: To find the moment of inertia of multiple bodies, we need to use the parallel axis theorem. The parallel axis theorem states that the moment of inertia of a body about any axis parallel to its centroidal axis is equal to the moment of inertia about the centroidal axis plus the product of the body's mass and the square of the distance between the two axes.
Here are the steps to find the moment of inertia of multiple bodies:
Find the moment of inertia of each body about its centroidal axis using the appropriate formula for that body. For example, the moment of inertia of a solid cylinder about its central axis is 1/2MR^2, where M is the mass of the cylinder and R is the radius of the cylinder.
Determine the centroid of the system of bodies. This is the point through which the axis of rotation passes and is the point about which the moment of inertia is calculated.
Calculate the distance between the centroid and each body's centroidal axis.
Use the parallel axis theorem to find the moment of inertia of each body about the axis passing through the centroid of the system. Add up all the moments of inertia of each body about the centroid of the system to get the total moment of inertia.
The formula for the parallel axis theorem is:
I = I_cm + md^2
where I is the moment of inertia about the axis passing through the centroid of the system, I_cm is the moment of inertia about the centroidal axis of the body, m is the mass of the body, and d is the distance between the two axes.
By using this formula, we can find the moment of inertia of any system of bodies with respect to any axis parallel to the centroidal axis.

Step-by-step explanation:
2) The standard form equation for a circle is ...
(x -h)^2 +(y -k)^2 = r^2
You are given the center: (h, k) = (3, -2) and a point on the circle. So, the equation will be ...
(x -3)^2 +(y +2)^2 = r^2
Since we know a point on the circle we know that ...
(7 -3)^2 +(1 +2)^2 = r^2 = 16 +9 = 25
So, the circle's equation is ...
(x -3)^2 +(y +2)^2 = 25 . . . . . matches choice C
__
5) As in the previous problem, the standard form equation is ...
(x -4)^2 +(y -8)^2 = (-1-4)^2 +(7-8)^2 = 25+1 = 26
To put this in general form, we need to subtract 26 and eliminate parentheses.
x^2 -8x +16 +y^2 -16y +64 -26 = 0
x^2 +y^2 -8x -16y +54 = 0

x^2 +y^2 -10x -12y +36 = 0
A certain rectangular prism has a height of 4 m, a length of 3 m, and a width of 7 m. Give the dimensions of a second rectangular prism that will have the same surface area of the first one.
PLEASE HELP 50 POINTS
To find the dimensions of the second rectangular prism that will have the same surface area as the first one, we can use the formula for the surface area of a rectangular prism which is:
Surface Area = 2lw + 2lh + 2wh
where l is the length, w is the width, and h is the height of the rectangular prism.
For the first rectangular prism, we have:
l = 3 m w = 7 m h = 4 m
Surface Area = 2lw + 2lh + 2wh Surface Area = 2(3)(7) + 2(3)(4) + 2(7)(4) Surface Area = 42 + 24 + 56 Surface Area = 122 m²
To find the dimensions of the second rectangular prism that will have the same surface area as the first one, we can use this formula again and solve for one of the variables. Let’s solve for l:
Surface Area = 2lw + 2lh + 2wh 122 = 2l(w+h) + 2wh 122 = 2l(w+h) + w(4) 122 = 2l(w+h) + 4w 118 = l(w+h)
Now we can choose any value for w and h and solve for l. Let’s choose w=1 and h=1:
118 = l(1+1) 118 = l(2) l = 59
So the dimensions of the second rectangular prism that will have the same surface area as the first one are:
l = 59 m w = 1 m h = 1 m

solve sinx = 2x-3 using false position method
The root of the equation sinx = 2x-3 is 0.8401 (approx).
Given equation is sinx = 2x-3
We need to solve this equation using false position method.
False position method is also known as the regula falsi method.
It is an iterative method used to solve nonlinear equations.
The method is based on the intermediate value theorem.
False position method is a modified version of the bisection method.
The following steps are followed to solve the given equation using the false position method:
1. We will take the end points of the interval a and b in such a way that f(a) and f(b) have opposite signs.
Here, f(x) = sinx - 2x + 3.
2. Calculate the value of c using the following formula: c = [(a*f(b)) - (b*f(a))] / (f(b) - f(a))
3. Evaluate the function at point c and find the sign of f(c).
4. If f(c) is positive, then the root lies between a and c. So, we replace b with c. If f(c) is negative, then the root lies between c and b. So, we replace a with c.
5. Repeat the steps 2 to 4 until we obtain the required accuracy.
Let's solve the given equation using the false position method.
We will take a = 0 and b = 1 because f(0) = 3 and f(1) = -0.1585 have opposite signs.
So, the root lies between 0 and 1.
The calculation is shown in the attached image below.
Therefore, the root of the equation sinx = 2x-3 is 0.8401 (approx).
