Suppose point P divides the directed line segment XY so that the ratio of XP to PY is 3 to 5. Describe the point that divides directed line segment YX so that the ratio of YP to PX is 5 to 3.
The point that divides the directed line segment YX so that the ratio of YP to PX is 5 to 3 is P.
According to the question,
We have the following information:
Point P divides the directed line segment XY so that the ratio of XP to PY is 3 to 5.
Now, when the line segment XY is inverted to call the line segment YX then the point P is still there.
And the point P divided the line segment in the same way but the difference is that the measurement are taken from the other side. But the point P has not been removed because it is common in YP and PX and YX (as we observe even from the name of these smaller segments) is the line segment.
Hence, P is the point dividing the line segment YX into the given ratio.

Find three consecutive odd integers such that the sum of the smaller two is three times the largest increased by seven.
Consecutive odd numbers are odd integers that are separated by 2 and come after one another. If the number x is odd, then the numbers x + 2, x + 4, and x + 6 are also odd.
Explain about the consecutive odd integers?The next two odd consecutive integers are (2n + 3) and (2n + 5) if 2n + 1 is an odd number. For illustration, assume that 2n + 1 is the odd number 7. Its successive numbers are identified as (7 + 2) and (7 + 4), or 9 and 11.
Three consecutive odd numbers that are 3, 5, and 7 are all prime. Three successive odd numbers that are not all prime are 109, 111, and 113 (111=37 times 3).
Answer
Let x - 2, x, and x + 2 be the three odd numbers.
x - 2 + x = 3(x + 2) + 7
2x - 2 = 3x + 6 + 7
2x - 2 = 3x + 13
3x - 2x = -2 - 13
x = -15

B∩C = Nil
Xc∩Yc = {February, April, August, September, November, December}
(YUZ)c= {February, March, April, May, August}
the symbol c stands for complement in the solution.
Step-by-step explanation:
union is combining all the elements of sets A and B
AUB = {0,1,2,3,4,6,8}
intersection is combining only the common elements present in both B and C
B∩C = Nil
complement of a set is the number of elements that are not present in the set.
Xc = {January, February, April, August, September, November, December}
Yc= {February, March, April, May, August, September, October, November, December}
Xc∩Yc = {February, April, August, September, November, December}
Y∪Z = {January, June, July, September, October, November, December}
(YUZ)c= {February, March, April, May, August}
the symbol c stands for complement in the solution.
Answer:
A⋃B = {0, 1, 2, 3, 4, 6, 8} B⋂C = { } . . . (the empty set) X'⋂Y' = {Feb, Apr, Aug, Sep, Nov, Dec} (Y⋃Z)' = {Feb, Mar, Apr, May, Aug}Step-by-step explanation:
Given various set definitions, you want to find the union and the intersection of specific pairs of sets.
We find it convenient to list the set contents in such a way that we can readily identify elements in one set or another, neither, or both. That is what we have done in the attachment.
1. A⋃BThe union of sets A and B will be the list of elements in either set. That is, if an element is included in set A or in set B, it is included in their union. An element is only listed once, even if it appears in both sets.
A⋃B = {0, 1, 2, 3, 4, 6, 8}
2. B⋂CThe intersection of sets B and C will be the list of elements contained in both sets. Set B is even digits, and set C is odd digits. Since there are no digits that are both even and odd, their intersection is the empty set.
B⋂C = { } . . . (the empty set)
3. X'⋂Y'The intersection of the complements of sets X and Y is the list of elements of U that are not in either set.
X'⋂Y' = {Feb, Apr, Aug, Sep, Nov, Dec}
4. (Y⋃Z)'The complement of the union of Y and Z is the list of elements of U that are not in either of sets Y or Z. This is effectively the same as Y'⋂Z'.
(Y⋃Z)' = {Feb, Mar, Apr, May, Aug}

The length of the indicated lines segments are as follows:
HI = 10 unitsHJ = 20 unitsHow to find length of a line segment?The line segment is given and we are ask to find the length HI and HJ in the line segment.
Therefore, let's find HI
13.
HI = x - 2
GI = 13
HJ = 2x + 2
GJ = 4x - 19
Hence,
GH = 4x - 19 - (2x + 2)
GH = 13 - (x - 2)
Therefore,
4x - 19 - 2x - 2 = 13 - x + 2
2x - 21 = 15 - x
2x + x = 15 + 21
3x = 36
x = 36 / 3
x = 12
Therefore,
HI = x - 2 = 12 - 2 = 10
12.
Let's find HJ
HJ = x + 30
IJ = 2x + 26
HK = x + 33
IK = 9
Therefore,
JK = x + 33 - (x + 30) = x + 33 - x - 30 = 3
JK = 9 - (2x + 26) = 9 - 2x - 26 = -2x - 17
Therefore,
-2x - 17 = 3
-2x = 3 + 17
-2x = 20
x = 20 / - 2
x = - 10
Therefore,
HJ = -10 + 30 = 20 units

In his spare time, Kim likes to go cycling. He cycles partly on paved surfaces and partly off-road, through hilly and wooded areas. He cycles at 25km/h on paved surfaces and at 10 km/h off-road. One day, he cycled 41 km in 2 hours. How far did he cycle on the paved road and how far off-road?
Kim travelled 35 km on a paved surface and 6 km off-road which took 1.4 hours and 0.6 hours respectively
Speed of Kim when cycling on paved surfaces: 25 km/hr
Speed of Kim when cycling off-road = 10 km/hr
Distance covered by Kim = 41 km
Time is taken by Kim = 2 hours
Let x be the time Kim travels on a paved surface, and y represents the time off-road
Using the formula:
Speed = Distance/Time
Distance travelled by Kim on paved surface = 25*x
Distance travelled by Kim off-road = 10*y
x + y = 2-------(1)
25x + 10y = 41-------(2)
Multiplying equation (1) with 25 and equating with (2) we get:
25x + 25y = 50
25x + 10y = 41
15y = 9
y = 0.6 hours
x = 1.4 hours
Distance travelled on paved surface = 25*1.4 = 35 km
Distance travelled off-road = 10*0.6 = 6km

Rebecca needs 10 1/2 yards of fabric to make a quilt. she has one piece of fabric that is 2 1/2 yards and another piece of fabric that is 4 1/4 yards. how many more yards of fabric does does Rebbeca need to make a quilt
pls put step by step
The most appropriate choice for fraction will be given by -
Rebeca still needed [tex]3\frac{3}{4}[/tex] yards of fabric to make a quilt.
What is a fraction?
Suppose there is a collection of objects and a part of collection has been taken. The part which is taken is called fraction. In other words, part of a whole is called fraction.
The upper part of fraction is called numerator and the lower part of fraction is called denominator.
Here,
Length of fabric needed to make a quilt = [tex]10\frac{1}{2}[/tex] yards = [tex]\frac{21}{2}[/tex] yards
Length of one piece of fabric = [tex]2\frac{1}{2}[/tex] yards = [tex]\frac{5}{2}[/tex] yards
Length of another piece of fabric = [tex]4\frac{1}{4}[/tex] yards = [tex]\frac{17}{4}[/tex] yards
Total length of fabric Rebeca has = [tex]\frac{5}{2} + \frac{17}{4}\\[/tex]
= [tex]\frac{10 + 17}{4}\\[/tex]
= [tex]\frac{27}{4}[/tex] yards
Length of Fabric Rebeca still needed to make a quilt = [tex]\frac{21}{2} - \frac{27}{4}\\[/tex]
= [tex]\frac{42 - 27}{4}[/tex]
= [tex]\frac{15}{4}[/tex]

What is meant by the inverse of the function?An inverse function, also known as an anti function, is a function that can be reversed into another function. Simply put, if any function "f" takes x to y, then its inverse will take y to x. The inverse function is signified by f-1 or F-1 if the function is signified by 'f' or 'F'. Here, (-1) should not be confused with exponent or reciprocal.For the given question,
The functions as given as;
f(x) = x/3 + 1
g(x) = x³
Now, the find the composite function f o g (x).
Put the value of g(x) at the place of x in f(x).
f o g (x) = x³/8 + 1
Let the obtained composite function be y.
y = f o g (x) = x³/8 + 1
Find the value of x in terms of y.
y = x³/8 + 1
y - 1 = x³/8
8(y - 1) = x³
taking cube root.
x = 2 ∛(y - 1)
Now, substitute the value of x in place of y.
(f o g )⁻¹(x) = 2 ∛(x - 1)
Now, put the value of x as 5.
(f o g )⁻¹(x) = 2 ∛(x - 1)
(f o g )⁻¹(5) = 2 ∛(5 - 1)
Thus, the value of the composite inverse function is obtained as 2 ∛(5 - 1).
