W = 2V₁ - V₂ + 3V₃ - 4V₄ = -V₁ + 2V₂ - V₃ + 3V₄

To express vector W as a linear combination of vectors V₁, V₂, V₃, and V₄, we need to find the coefficients that multiply each vector to obtain W. In the first expression, W is written as a linear combination of V₁, V₂, V₃, and V₄ with specific coefficients: 2 for V₁, -1 for V₂, 3 for V₃, and -4 for V₄. This means that we take two times V₁, subtract V₂, add three times V₃, and subtract four times V₄ to obtain W.

In the second expression, the coefficients are different. W is expressed as a linear combination of V₁, V₂, V₃, and V₄ with coefficients: -1 for V₁, 2 for V₂, -1 for V₃, and 3 for V₄. This means that we take negative V₁, add two times V₂, subtract V₃, and add three times V₄ to obtain W.

By finding these two different expressions, we can see that there are multiple ways to represent W as a linear combination of V₁, V₂, V₃, and V₄. The choice of coefficients determines the specific combination of the vectors that make up W.

Step-by-step explanation:

Alessia spent $5,408 on entertainment in 2021.

To determine how much Alessia spent on entertainment in 2021, we need to work backward from the given information about her salary in 2022.

Let's assume Alessia's salary in 2021 was the same as in 2022, which is $26,000 after tax.

Since Alessia spends 35% of her after-tax salary on rent, we can calculate her rent expenditure:

Rent = 35% × $26,000

= $9,100

The remaining amount is split between food, petrol, and entertainment in the ratio 6:11:8.

To determine the ratio's total parts, we sum the individual parts:

Total parts = 6 + 11 + 8 = 25

Next, we calculate the value of one part of the ratio:

One part = ($26,000 - $9,100) / 25

= $16,900 / 25

= $676

Now, we can calculate how much Alessia spent on entertainment in 2021, which is 8 parts of the ratio:

Entertainment expenditure = 8 × $676

= $5,408

The equation of a line that passes through the point (-4, 3) with slope -5/4 is equal to y = -5x/4 - 2.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

m represents the slope.

x and y represents the data points.

From the information provided above, we have the following slope and data points on the line:

At data point (-4, 3), a linear equation of this line can be calculated in point-slope form as follows:

y - y₁ = m(x - x₁)

y - 3 = -5/4(x - (-4))

y - 3 = -5/4(x + 4)

y = -5x/4 - 5 + 3

Answer:

\(A_X=\frac{15x^2}{16}\)

Step-by-step explanation:

From the question we are told that:

Base of Flower bed \(b=\frac{x}{2}\)

Height of Flower bed \(h=\frac{x}{4}\)

Generally the equation for Area of garden left A_X is mathematically given by

 \(A_X=Area\ of\ Garden\ A_g\ - Area\ of\ flower\ bed\ A_f\)

Where

 \(A_f=b*h\)

 \(A_f=\frac{1}{2}*\frac{x}{2}*\frac{x}{4}\)

 \(A_f=\frac{x^2}{16}\)

Therefore

 \(A_X= A_g - A_f\)

 \(A_X=x^2-\frac{x^2}{16}\)

 \(A_X=\frac{15x^2}{16}\)

Given:

The vertices of triangle FGH are F(-2,1), G(1,3) and H(0,5).

To find:

The vertices of F'G'H' for a reflection over the y-axis.

Solution:

If a figure is reflected over the y-axis, then

\((x,y)\to (-x,y)\)

Using this rule of reflection, we get

\(F(-2,1)\to F'(-(-2),1)\)

\(F(-2,1)\to F'(2,1)\)

Similarly,

\(G(1,3)\to G'(-1,3)\)

\(H(0,5)\to H'(0,5)\)

The vertices of F'G'H' are F'(2,1),G'(-1,3), H'(0,5). Therefore, the correct option is B.

To record the critical values for a chi-square test, we need to know the degrees of freedom in addition to the level of significance. Assuming the degrees of freedom are not given, I will provide the critical values for degrees of freedom (k-1) at each level of significance:

At 10% level of significance:

- df = 9, Chi-square critical value = 14.6846

- df = 15, Chi-square critical value = 23.6848

- df = 21, Chi-square critical value = 31.4104

At 16% level of significance:

- df = 9, Chi-square critical value = 16.9189

- df = 15, Chi-square critical value = 26.2962

- df = 21, Chi-square critical value = 34.1694

At 22% level of significance:

- df = 9, Chi-square critical value = 19.0228

- df = 15, Chi-square critical value = 29.1407

- df = 21, Chi-square critical value = 37.5662

The critical values for a chi-square test increase with increasing degrees of freedom and increasing level of significance.

To find the dimensions of the bookmark, we need to use the given information about its perimeter and area. The dimensions of the bookmark are 4 centimeters by 8 centimeters.

Let's start by using the formula for the perimeter of a rectangle, which is P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
We know that the perimeter of the bookmark is 24 centimeters, so we can write:
24 = 2(l + w)
Simplifying this equation, we get:
12 = l + w
Now, let's use the formula for the area of a rectangle, which is A = lw, where A is the area, l is the length, and w is the width.
We know that the area of the bookmark is 32 square centimeters, so we can write:
32 = lw
Next, we can use the fact that l + w = 12 to solve for one of the variables in terms of the other. For example, we can solve for l:
l = 12 - w
Substituting this into the equation for the area, we get:
32 = (12 - w)w
Expanding this equation, we get:
32 = 12w - w^2
Rearranging and simplifying, we get a quadratic equation:
w^2 - 12w + 32 = 0
We can solve this equation using the quadratic formula:
w = (12 ± √(12^2 - 4(1)(32))) / (2(1))
Simplifying, we get:
w = 4 or w = 8
If w = 4, then l = 8 (since l + w = 12). If w = 8, then l = 4.
Therefore, the dimensions of the bookmark are either 8 centimeters by 4 centimeters, or 4 centimeters by 8 centimeters.

To find the dimensions of the bookmark with a perimeter of 24 centimeters and an area of 32 square centimeters, follow these steps:
1. Let the length be "L" centimeters and the width be "W" centimeters.
2. The formula for perimeter is P = 2L + 2W. Since the perimeter is 24 centimeters, we have the equation: 24 = 2L + 2W.
3. The formula for area is A = LW. Since the area is 32 square centimeters, we have the equation: 32 = LW.
4. To solve for one of the variables, we can simplify the perimeter equation: 12 = L + W.
5. Next, we can solve for one of the variables in terms of the other. Let's solve for W: W = 12 - L.
6. Now, substitute W in the area equation: 32 = L(12 - L).
7. Expand the equation: 32 = 12L - L^2.
8. Rearrange to form a quadratic equation: L^2 - 12L + 32 = 0.
9. Factor the equation: (L - 4)(L - 8) = 0.
10. Solve for L: L = 4 or L = 8.
11. Use the value of L to find W: If L = 4, W = 12 - 4 = 8; If L = 8, W = 12 - 8 = 4.
The dimensions of the bookmark are 4 centimeters by 8 centimeters.

Relative humidity:

                             Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 % relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. This doesn't mean that the relative humidity must be 100 percent in order for it to rain — it must be 100 percent where the clouds are forming, but the relative humidity near the ground could be much less.

0% humidity means there is an absence of water vapor in the air.

Step-by-step explanation:

b)  The number of roots, doubled tripled etc, should add up to degree.  We know that the curve is even becuase both ends are facing downward..  So the roots/solutions/zeroes, should add up to an even amount.

Roots happen when the curve hits the x-axis

Root (-2,0) is a single root because it goes right through the x-axis

Root (1,0) is a triple.   It does not go right through like a single,  it does not bounce off (like a parabolic shape) that's a double.  This tripe goes through but squiggles through so it's a triple.

C)  We will use factored form and the roots. Each root goes in a parenthesis, opposite sign.   If doubled will be squared, tripled will be cubed.  Also there is a negative in the front because it is a negative curve.
