[tex]$W(\mathbf{x})$[/tex]is a linear transformation. it is not onto .The given statement is false.
The objective is to determine whether the following statement is true or false.
"If [tex]$$T_1(\mathbf{x})$ and $T_2(\mathbf{x})$[/tex] are onto linear transformations from [tex]$\mathbf{R}^n$[/tex] to [tex]$\mathbf{R}^m$[/tex] then [tex]$W(\mathbf{x})=T_1(\mathbf{x})+T_2(\mathbf{x})$[/tex] is an onto linear transformation."
To check whether [tex]$W(\mathbf{x})$[/tex] is a linear transformation or not:
For a, b ∈ R and for x, y ∈ [tex]$\mathbf{R}^n$[/tex],
[tex]$$\begin{aligned}W(a \mathbf{x}+b \mathbf{y})= & T_1(a \mathbf{x}+b \mathbf{y})+T_2(a \mathbf{x}+b \mathbf{y}) \quad\left(\text { Since } W(\mathbf{x})=T_1(\mathbf{x})+T_2(\mathbf{x})\right) \\= & {\left[a T_1(\mathbf{x})+b T_1(\mathbf{y})\right]+\left[a T_2(\mathbf{x})+b T_2(\mathbf{y})\right] } \\& \quad\left(\text { Since } T_1(\mathbf{x}) \text { and } T_2(\mathbf{x}) \text { are onto linear transformations }\right) \\\end[/tex]
[tex]= & a\left[T_1(\mathbf{x})+T_2(\mathbf{x})\right]+b\left[T_1(\mathbf{y})+T_2(\mathbf{y})\right] \\\\= & a W(\mathbf{x})+b W(\mathbf{y})\end{aligned}$$[/tex]
Therefore, [tex]$W(\mathbf{x})$[/tex] is a linear transformation.
To check whether [tex]$W(\mathbf{x})$[/tex] is onto:
Define the linear transformations:
[tex]$$T_1: \mathbf{R} \rightarrow \mathbf{R}$ such that $T_1(\mathbf{x})=\mathbf{x}$[/tex]
[tex]$$T_2: \mathbf{R} \rightarrow \mathbf{R}$ such that $T_2(\mathbf{x})=-\mathbf{x}$[/tex]
Then, [tex]$T_2(\mathbf{x})=-\mathbf{x}=-T_1(\mathbf{x}) \Rightarrow T_2(\mathbf{x})=-T_1(\mathbf{x})$[/tex]
The range of both functions [tex]$T_1, T_2$ is $\mathbf{R}$[/tex] This is same as the co-domain of [tex]$T_1, T_2$[/tex]. So, they are onto functions.
If A and B are the two sets, if for every element of B, there is at least one or more element matching with set A, it is called the onto function.
Therefore, [tex]$T_1, T_2: \mathbf{R} \rightarrow \mathbf{R}$[/tex]are onto linear transformations.
And, [tex]$W=T_1+T_2: \mathbf{R} \rightarrow \mathbf{R}$[/tex] is a mapping.
Now, [tex]$W(\mathbf{x})=T_1(\mathbf{x})+T_2(\mathbf{x})$[/tex]
[tex]$$\begin{aligned}& =T_1(\mathbf{x})-T_1(\mathbf{x}) \\& =0\end{aligned}$$[/tex]
So, the range of [tex]$$W(\mathbf{x})$ is $\{0\} \neq \mathbf{R}($[/tex] co-domain of [tex]$W(\mathbf{x}))$[/tex]
Then, is [tex]$W(\mathbf{x})$[/tex] not onto.
So, the given statement is false.
Hence, the correct answer is 5th option

Find g(x), where g(x) is the reflection across the x-axis of f(x)=-9x+10.
Lucy wants to but a new car but needs money for the down payment. Her parents agree to lend her money at an annual rate of 5%, charged as simple interest. They lend her $4000 for 2 years. She makes no payments except the one at the end of that time.
Answer the following questions:
How much total interest will Lucy have to pay?
What will the total repayment amount be (including interest)
Answer:
To calculate the total interest that Lucy will have to pay, we need to use the formula for simple interest: I = P * R * T, where I is the interest, P is the principal (the amount borrowed), R is the interest rate (as a decimal), and T is the time in years. Using this formula, we can calculate the total interest that Lucy will have to pay as follows:
I = P * R * T
I = $4000 * 0.05 * 2
I = $400
Therefore, the total interest that Lucy will have to pay is $400.
________________________________________________________
To calculate the total repayment amount (including interest), we need to add the total interest to the original amount borrowed, which in this case is $4000. Therefore, the total repayment amount will be $4000 + $400 = $4400. This is the amount that Lucy will have to pay back to her parents at the end of the two-year period.
Step-by-step explanation:
Answer:
Total interest = $400
Total repayment (including interest) = $4,400
Step-by-step explanation:
Simple Interest Formula
[tex]\large\boxed{ \sf I = Prt}[/tex]
where:
I = Total interest.P = Principal amount.r = Interest rate (in decimal form).t = Time (in years).Given:
P = $4,000r = 5% = 0.05t = 2 yearsTo find the total interest, substitute the given values into the formula and solve for I:
[tex]\implies \sf I=4000 \cdot 0.05 \cdot 2[/tex]
[tex]\implies \sf I=200 \cdot 2[/tex]
[tex]\implies \sf I=400[/tex]
Therefore, the total interest Lucy has to pay is $400.
The total repayment amount is the sum of the principal and the interest:
[tex]\implies \sf A=P+I[/tex]
[tex]\implies \sf A=4000 +400[/tex]
[tex]\implies \sf A=4400[/tex]
Therefore, the total repayment (including interest) is $4,400.

the degrees of freedom for a chi-square test of independence for the following data is 5. group of answer choices true false
The number of independent pieces of information used to calculate a statistic is called the degrees of freedom, which is frequently denoted by the letters v or df. I
What is the degree of freedom?Itbis determined by subtracting the number of restrictions from the sample size. Subtract the number of relations from the number of observations to determine degrees of freedom. You need to deduct one (1) from the total number of observations, n, in order to calculate the degrees of freedom for a sample mean or average.
The degrees of freedom for the chi-square are calculated as df = (r-1)(c-1) where
r = the number of rows
c = the number of columns.
If the observed chi-square test statistic is greater than the critical value, the null hypothesis can be rejected.

If both bouquets have 6 tickseeds, the first bouquet ( roses + tickseeds) has more flowers.
The problem can be solved using ratio.
Bouquet 1 :
Every 2 tickseeds there are 7 roses
Hence, the ratio
Tickseed : rose = 2 : 7
If there are 6 tickseeds, then
2 : 7 = 6 : rose
rose = (6/2) x 7 = 21
Number of flowers = 6 tickseeds + 21 roses = 27 flowers
Bouquet 2 :
Every 3 tickseeds there are 4 daisies
Hence, the ratio
Tickseed : daisy = 3 : 4
If there are 6 tickseeds, then
3 : 4 = 6 : daisy

Which do you prefer: leaving √5 in radical form, or converting it to a decimal? Why? When would it be useful to use each?
I would prefer leaving the answer as a radical number as √5 since it is a shorter form and exact form of the answer.
How to express radical numbers?My reasons for leaving it as a radical form or a decimal approximation are;
1) If we are trying to find an exact answer, then we should leave it as √5. For example, if we are told a square has an area of 5 square units, then it means that the exact length of the side is √5 units.
2) If √5 is the length of an object that has to be made to that specific length, then we would require an approximation. For example, if you are asked to make a square out of cardboard whose area is 5 square feet, then we will definitely need an approximation of √5 ft = 2.24 ft, which would help us make each side of the cardboard square in the length of 2.24 ft.

The average age of ceo's is 56 years. Assume the random variable is normally distributed. If the standard deviation is 4 years, find the probability that the age of a ceo is between 50 and 56 years old.
There is a probability of 33.45% that the age of randomly selected CEO will be between 50 and 55 years old.
What does the math term "probability" mean?
The simple definition of probability is the likelihood that something will occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out.
Statistics is the study of events that follow a probability distribution.
Given that:
Mean = 56, standard deviation = 4, For 50:
z = (50 - 56) / 4 = -1.5
For 44:
z = (55 - 56) / 4 = -0.25
P(50 < x < 55) = P(z < -0.25) - P(z < -1.5) = 0.4013 - 0.0668 = 33.45

6x-3y= -21
4x=3y-9
Help
Answer:
The answer is x = -6 and y = -5.
Step-by-step explanation:
To solve this problem, we can use substitution. Let's first solve one of the equations in terms of the variable y, and then substitute this value into the other equation.
4x = 3y - 9
3y = 4x + 9
Since the term "3y" is present in the other equation given, we can substitute the right side of this equation (4x + 9) into the other equation for 3y. This is shown below.
6x - 3y = -21
6x - (4x + 9) = -21
6x - 4x - 9 = -21
We can simplify the left side of the equation and solve for x.
2x - 9 = -21
2x = -12
x = -6
Now, we can substitute this value for x into one of our equations to solve for y.
4x = 3y - 9
4(-6) = 3y - 9
-24 = 3y - 9
-15 = 3y
y = -5
Therefore, the correct answer is x = -6 and y = -5.

Hello. Could someone help me to solve this question? The answer is 86.61cm.
The perimeter of the whole diagram in cm is derived as 86.6158 cm using trigonometric ratios.
Trigonometric ratiosThe trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.
Considering the angle P for right-angled triangle formed by extending the line PQ to the base of the trapezium, so that we have opposite side of 7 cm (22 cm - 15 cm)
so; sinP = 7/25.3
P = sin^(-1)(7/25.3)
P = 16.06
The isosceles triangle PQR have the angle;
Q = 180 - 2(16.06) {sum of interior angles of Isosceles triangle with two equal base angles}
Q = 147.88°
Considering the smaller right-angled triangle formed by the height of the trapezium and one side of the Isosceles triangle, we have its angle;
Q = 180° - 147.88° {sum of angles on a straight line}
Q = 32.12
also;
sin32.12 = 7/hypotenuse (one of the equal sides of the Isosceles triangle)
hypotenuse = 7/sin32.12
hypotenuse = 13.1655
The length TS is equal to the adjacent side of the smaller triangle, so;
cos32.12 = TS/13.1655
TS = 13.1655 × cos32.12
TS = 1.51503
Therefore, the perimeter of the whole diagram is;

After solving this problem, Juan was very clever and invented the following strange question:
A building, in the shape of a rectangular prism with a square base, has on its top a radio tower. The
building is 25 times as tall as the tower, and the side-length of the base of the building is 100 feet less than
the height of the building. If the building has a volume of 2 million cubic feet, how tall is the tower?
The tower is 24 feet tall.
To solve this problem, we need to use the formula for the volume of a rectangular prism, which is V = l × w × h, where l and w are the length and width of the base and h is the height.
We are given that the side length of the base of the building is 100 feet less than the height of the building, so the height of the building is h = l + 100, where l is the side length of the base. We can substitute this expression for h into the formula for the volume of the building:
V = l × w × (l + 100) = 2 million cubic feet
Since the building is 25 times as tall as the tower, the height of the tower is h = (1/25) × h = (1/25) × (l + 100). Substituting this expression for h into the formula for the volume of the building, we get:
V = l × w × (1/25) × (l + 100) = 2 million cubic feet
Solving this equation for l, we find that l = 500 feet. This is the side length of the base of the building, so the height of the building is h = l + 100 = 500 + 100 = 600 feet. The tower is (1/25) × 600 = 24 feet tall.

heart and star pls <3 brainliest will be appreciated <3(っ◔◡◔)っ -{ elyna s }-Which represents the reflection of f(x) = startroot x endroot over the x-axis? a 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 4. The second column is labeled f (x) with entries undefined, 0, negative 1, negative 2. A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 4. The second column is labeled f (x) with entries 1, 0, undefined, undefined.
The correct option is A: A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 4. The second column is labeled f (x) with entries undefined, 0, negative 1, negative 2.
Explain the reflection along the x-axis?In order to reflect over the X axis, one must negate that value of each point's y-coordinate while maintaining its x-value.The x-coordinate remains constant when a point is reflected across the x-axis, however the y-coordinate is assumed to be an additive inverse. Point (x, y) is reflected across the x-axis as (x, -y).The given function is;
f(x) = StartRoot x EndRoot , which is written as;
f(x) = √x
Domain for the x = [ 0 , ∞ )
x f(x)
-1 undefined
0 0
1 1
4 2
The reflection over x-axis.
f(x) ----> - f(x)
x f(x)
-1 undefined
0 0
1 -1
4 -2
Thus, the correct option is; A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 4. The second column is labeled f (x) with entries undefined, 0, negative 1, negative 2.

Yaqub has a bag only containing green and yellow pins. 3 of the pins are green. 7 He picks out a green pin from his bag and gives it to his sister. of the remaining pins in his bag are green. How many of the remaining pins in his bag are green and how many are yellow?
Answer:
The answer is that there are 2 green pins and 5 yellow pins remaining in the bag.
Step-by-step explanation:
There are 3 green pins in the bag at the start and Yaqub gives one to his sister, so there are 3 - 1 = <<3-1=2>>2 green pins remaining in the bag. The rest of the pins in the bag must be yellow, so there are 2 green and 7 - 2 = <<7-2=5>>5 yellow pins remaining in the bag.
Answer:2 green 5 yellow
