Given directed line segment AB determine point X on the graph such that X partions the segment A to B in a ratio of 1:4 and given its coordinates A(5,1) and b(-5,4)
(NEED THIS ASAP!!)
Answer:
The coordinates of point X that divides the line in 1:4 are: (3,8/5)
Step-by-step explanation:
When a point divides a line with coordinates (x1,y1) and (x2,y2) in ratio m:n,
the coordinates of point are given by:
[tex](x,y) = (\frac{mx_2+nx_1}{m+n} , \frac{my_2+ny_1}{m+n})[/tex]
Given points are:
(x1,y1) = (5,1)
(x2,y2) = (-5,4)
Putting the values in the formula
[tex]X(x,y) = (\frac{(1)(-5)+(4)(5)}{1+4} , \frac{(1)(4)+(4)(1)}{1+4})\\= (\frac{-5+20}{5}, \frac{4+4}{5})\\=(\frac{15}{5}, \frac{8}{5})\\=(3,\frac{8}{5})[/tex]
Hence,
The coordinates of point X that divides the line in 1:4 are: (3,8/5)
Use the figure to identify the correct rule for the translation. (x, y) Right-arrow (x – 3, y + 4) (x, y) Right-arrow (x + 3, y – 4) (x, y) Right-arrow (x – 4, y + 3) (x, y) Right-arrow (x + 4, y – 3)
Answer:
(x, y) Right-arrow (x – 3, y + 4)
(the top one)
applying the appropriate transactional rule When the coordinates are added to or subtracted from, the values of x and y change.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given four transformations of coordinates (x, y)
Mathematical transformations describe how 2D figures move around a plane or coordinate system.
If the transformation occurs in the x-axis, then the coordinators move left or right.If transformation occurs in the y-axis, then the coordinators move upwards or downwardsthus for (x, y ) => (x - 3), (y + 4)
From the given rule:
x is decreased by 3 and y is increased by 4 or in other words, we can say the graph moves downward by 3 units and to the right by 4 unit
for (x, y ) => (x + 3), (y - 4)
From the given rule:
x is increased by 3 and y is decreased by 4 or in other words, we can say the graph moves upward by 3 units and to the left by 4 units.
for (x, y ) => (x + 4), (y - 3)
From the given rule:
x is increased by 4 and y is decreased by 3 or in other words, we can say the graph moves upward by 4 units and to the left by 3 units.
Therefore, using the correct rule of the transaction The value of x and y will increase or decrease by adding or subtracting from the coordinates.

What is the value of x in the proportion below?
1/2 / 4 = x/28
3 1/2
7 1/2
14
56
Answer:
A 3 1/2
Step-by-step explanation:
There are a number of ways that you can solve this
Method 1)
Since these proportions are set equal to each other, we know that x is also equivalent to 1/2. So, we need to find the whole-number that was multiplied by the first fraction (1/2/4) that gave us the second fraction (x/28).
So we need to divide the denominators
28/4 = 7
Now that we have that number, we will mutiply 1/2 by it because we know that whatever x is the 1/2 times 7 since 28 is 4*7:
1/2 * 7 = 3.5 or 3 1/2, so 3 1/2 is our answer...
Another way that we can solve this is by using the cross product (butterfly method)
Method 2)
Multiply 28 by 1/2 = 14.
Now we will divide 14 by 4. 14/4 = 3.5
3.5 = 3 1/2, so that is our answer.

if 5x+2y=20 and y=10, what is 3x?
Answer:
3x = 0
Step-by-step explanation:
Given,
y = 10
now,
5x+2y = 20
or, 5x+2×10=20
or, 5x = 20-20
or, 5x = 0
or, x = 0/5
or, x = 0
Again,
3x = 3×0 =0

What is the solution to this system of equations?
x = 12 − y
2x + 3y = 29
Answer:
x=11, y=1 or (11, 1)
Step-by-step explanation:
I used substitution to solve this. Basically wherever there's an x, I would fill it in as 12-y.
2(12-y)+3y=29
24+2y+3y=29
24+5y=29
subtract 24 from both sides
5y=5
divide by 5
y=1
Now substitute y back in to get x.
x=12-1
x=11
You can also graph this into desmos, and wherever they intercept, that's your answer. I hope this helps!

20 students voted for vanilla.
What percentage of the students chose chocolate as their favorite ice-cream flavor?
Answer:36%
Step-by-step have 12+18+20 which equals 50 and 18 out of 50 is 36%
The percentage of the students who chose chocolate as their favorite ice cream flavor will be 36%
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
It is given that, there are 18 students voted for chocolate,12 students voted for strawberry and 20 students voted for vanilla.
The total number of students = 18+12+20 = 50
A percentage of the students chose chocolate as their favorite ice cream flavor is,
%choclate = (Number of students voted for chocolate / Total student)×100
%choclate =(18/50)×100

given that cosec A= -2, sec B= -2, A and B lie in the same quadrant. Find sin (2A+2B)
help me please,
Answer:
sin (2A+2B) = 0
Step-by-step explanation:
Given that,
cosec A= -2 and sec B= -2, A and B lie in the same quadrant.
We need to find the value of sin (2A+2B).
[tex]A=cosec^{-1}(-2)\\\\=-30[/tex]
And
[tex]B=\sec^{-1}(-2)\\\\=120^{\circ}[/tex]
To find the value of sin (2A+2B) as follows :
sin [2(-30)+2(120)] = sin (-60+240)
=sin (180)
= 0
So, the value of sin (2A+2B) is qual to 0.

Evaluate the surface integral
S
F · dS
for the given vector field F and the oriented surface S. In other words, find the flux of F across S. For closed surfaces, use the positive (outward) orientation.
F(x, y, z) = yj − zk,
S consists of the paraboloid
y = x2 + z2, 0 ≤ y ≤ 1,
and the disk
x2 + z2 ≤ 1, y = 1.
Since S is closed, you can use the divergence theorem, which says
[tex]\displaystyle\iint_S \vec F(x,y,z) \cdot \mathrm d\vec S=\iiint_R \mathrm{div}\vec F(x,y,z)\,\mathrm dV[/tex]
where R is the interior of the surface S.
We have
div F (x, y, z) = ∂/∂x (0) + ∂/∂y (y) + ∂/∂z (-z) = 1 - 1 = 0
so the flux would be 0.
In this exercise we have to calculate the flux by the divergent theorem:
The flux would be ZERO
Since S is closed, you can use the divergence theorem, which says:
[tex]\int\limits\int\limits_s {F(x,y,z} \, ds= \int\limits \int\limits\int\limits_R {divF(x, y, z)} \, dv[/tex]
where R is the interior of the surface S. We have:
[tex]\nabla F (x, y, z) = 1-1= 0[/tex]
so the flux would be ZERO.
