The solutions {sin(x), sin(x) - cos(x)} are linearly Independent since the linear combination equals zero only when all the coefficients are zero
To test the given set of solutions {sin(x), sin(x) - cos(x)} for linear independence, we can check if the linear combination of the solutions equals the zero vector only when all the coefficients are zero.
Let's consider the linear combination:
c1sin(x) + c2(sin(x) - cos(x)) = 0
Expanding this equation:
c1sin(x) + c2sin(x) - c2*cos(x) = 0
Rearranging terms:
sin(x)*(c1 + c2) - cos(x)*c2 = 0
This equation holds for all x if and only if both the coefficients of sin(x) and cos(x) are zero.
From the equation, we have:
c1 + c2 = 0
-c2 = 0
Solving this system of equations, we find that c1 = 0 and c2 = 0. This means that the only solution to the linear combination is the trivial solution, where all the coefficients are zero
Therefore, the solutions {sin(x), sin(x) - cos(x)} are linearly independent since the linear combination equals zero only when all the coefficients are zero

The only solution to the linear combination being equal to zero is when both coefficients are zero. Hence, the given set of solutions {sin(x), sin(x) − cos(x)} is linearly independent.
To test the given set of solutions for linear independence, we need to check whether the linear combination of these solutions equals zero only when all coefficients are zero.
Let's write the linear combination of the given solutions:
c1 sin(x) + c2 (sin(x) - cos(x))
We need to find whether there exist non-zero coefficients c1 and c2 such that this linear combination equals zero for all x.
If we simplify this expression, we get:
(c1 + c2) sin(x) - c2 cos(x) = 0
For this equation to hold for all x, we must have:
c1 + c2 = 0 and c2 = 0
The second equation implies that c2 must be zero. Substituting this into the first equation, we get:
c1 = 0

Answer:
Triangles are not similar.
Step-by-step explanation:
Properties of the similarity of two triangles,
1). Corresponding angles of two triangles are equal in measure.
2). Corresponding sides of the similar triangles are proportional.
From the given triangles,
- Corresponding angles of the given triangles are not equal in measure.
- Ratios of the corresponding sides,
[tex]\frac{KM}{XY}=\frac{CM}{RY}= \frac{KC}{XR}[/tex]
[tex]\frac{53}{53}= \frac{54}{53}= \frac{64}{53}[/tex]
But these ratios are not equal.
Therefore, both the triangles are not similar.

5 years ago, john was half the age he will be in 8 years. How old is he?
Answer: John is now 18 years old
Step-by-step explanation:
Let, John's age is now x years.
5 years ago, he was (x - 5) years old
In 8 years, he will be (x + 8) years old
By the given condition,
x - 5 = 1/2 (x + 8)
⇒ 2 (x - 5) = x + 8
⇒ 2x - 10 = x + 8
⇒ 2x - x = 8 + 10
⇒ x = 18

6 Work out the sizes of the angles labelled rº, sº and tº.
Plzzzz help I suck at geometry
Answer:
t = 30
s = 25
r = 55
Step-by-step explanation:
Let's begin by r
r is angle in quadlitral shape, so the sum of the interior angles = 360
r = 360 - (95 +100+110) = 55
Then Now it's time for ( t )
Look at the triangle whose angles are r, 95 and t. The sum of the measures of the interior angles of triangle is 180
so t = 180 - ( 95 + r) = 180 - (95 + 55) = 30
Similarly, look at the triangle whose angles are r, s and 100
s = 180 - (100 + r) = 180 - (100 + 55) = 25

A water tank holds 1,088 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds
1,360 gallons but is leaking at a rate of 9 gallons per week. After how many weeks will the amount of
water in the two tanks be the same?
The amount of water in the two tanks will be the same in
weeks.
The first tank hold 1088 - 5t gallons of water after t weeks, while the seocnd tank holds 1360 - 9t gallons after t weeks.
Both tanks hold the same amount of water when
1088 - 5t = 1360 - 9t
Solve for t :
4t = 272
t = 68
So the tanks will hold the same amount of water after 68 weeks.

Step-by-step explanation:
The image of rectangle EFGH after a reflection over the line x = –1 will cover the points G (1,7), H (2,7), F (1,-1), and E (2,-1).
What is a translation?The process of changing the location of the image on the coordinate system will be known as the translation. A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that graph the image of rectangle EFGH after a reflection over the line x= –1. Translated image of the points is attached with the answer below. The translated points are G (1,7), H (2,7), F (1,-1), and E (2,-1).

The shadows of two vertical poles were measured at the same time to be 6m and 15m long. If the first pole is 8cm long, find the height of the second pole
Answer:
20 cm
Step-by-step explanation:
Shadow of vertical poles : 6m ; 15m
Length of poles : 8cm ; h
8cm long pole = shadow length, 6m
h cm long pole = shadow length, 15 m
Using cross multiplication :
8cm * 15 m = h cm * 6m
120 = 6h
h = 120 / 6
h = 20 cm
Height of second pole = 20cm
