Answer:

Step-by-step explanation:

using the identity

cos²x = 1 - sin²x

consider the left side

\(\frac{1-cosx}{sinx}\)

multiply numerator/ denominator by (1 + cosx)

= \(\frac{(1-cosx)(1+cosx)}{sinx(1+cosx)}\) ← expand numerator

= \(\frac{1-cos^2x}{sinx(1+cosx)}\)

= \(\frac{sin^2x}{sinx(1+cosx)}\) ← cancel sinx on numerator/ denominator

= \(\frac{sinx}{1+cosx}\)

= right side , thus proven

Gentiana has $12 left to spend on the pizza pie as of the equation model.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,

Let the amount spend on pizza pie be x,
According to the question,
40 = 10 + 25% of 40 + 20% of 40 + x

40 = 10 + 40 × 0.25 + 40 × 0.20 + x
40 = 10 + 10 + 8 + x
x = 40 - 28
x = 12

Thus, Gentiana has $12 left to spend on the pizza pie as of the situation model.

d. It is impossible to determine how the Gini coefficient will change as it will depend on the original income distribution.

The Gini coefficient is a measure of income inequality in a society. It takes into account the entire income distribution, not just the average or total increase in income. The change in the Gini coefficient depends on how the income increase is distributed among different income groups.

If the income increase is distributed equally among all households, then the Gini coefficient would stay the same because the relative income differences between households remain unchanged. However, if the income increase is concentrated among higher-income households, it is likely that the Gini coefficient would increase, indicating a higher level of income inequality.

On the other hand, if the income increase is disproportionately distributed to lower-income households, it is possible for the Gini coefficient to decrease, indicating a reduction in income inequality.

Therefore, without knowing the initial income distribution and how the income increase is distributed across households, it is impossible to determine how the Gini coefficient will change over the 10-year period.

Answer: x-6, x+3, x-3

Step-by-step explanation;

Split the equation into two.

x2(x-6)-9(x-6)

(x-6) is seen as one of the tiles. Now work on x2-9

x2-9 is a difference of squares meaning the last two are (x+3) and (x-3).

L1 and L2 are intersecting lines is (0.8462, 0.4359).

When two lines intersect each other, it means that they have a common point. This point is known as the point of intersection.

In the given, we are given two lines, L1 and L2. We need to determine whether these lines intersect each other or not.

We can do this by comparing the slopes of the two lines. If the slopes are equal, then the lines are parallel and do not intersect each other. If the slopes are not equal, then the lines intersect each other.

Let's find the slopes of the given lines: Equation of line L1: 2x + 3y = 4We can rewrite this equation in slope-intercept form, y = mx + b, by solving for y:3y = -2x + 4y = (-2/3)x + 4/3The slope of line L1 is -2/3.

Equation of line L2: 4x - 5y = 3We can rewrite this equation in slope-intercept form, y = mx + b, by solving for y:-5y = -4x + 3y = (4/5)x - 3/5The slope of line L2 is 4/5.

Since the slopes of the two lines are not equal, we can conclude that the lines intersect each other. Now we need to find the point of intersection.

To find the point of intersection, we can solve the two equations of the lines simultaneously.2x + 3y = 4 ------------(1)4x - 5y = 3 ------------(2)Multiplying equation (1) by 4 and equation (2) by 3, we get:8x + 12y = 16 ------------(3)12x - 15y = 9 ------------(4)Multiplying equation (4) by 8, we get:96x - 120y = 72 ------------(5)Adding equations (3) and (5), we get: 104x = 88 Dividing by 104,

we get x = 0.8462 Substituting this value of x in equation (1), we get:2(0.8462) + 3y = 4Simplifying, we get: y = 0.4359 Therefore, the point of intersection of lines L1 and L2 is (0.8462, 0.4359).

Nolan and his children went into a grocery store and he bought $9 worth of apples and bananas, The three ways are explained below

Generally, One way to determine the number of apples, x, and the number of bananas, y, that Nolan bought is to use the equation:

x + y = a (total number of apples and bananas)

0.75x + 0.5y = 9 (total cost of apples and bananas)

Another way is to use the equation:

x = y + 2 (number of apples is 2 more than the number of bananas) 0.75x + 0.5y = 9 (total cost of apples and bananas)

A third way is to use the equation

y = x - 2 (number of bananas is 2 less than the number of apples)

0.75x + 0.5(x-2) = 9 (total cost of apples and bananas)

You can then solve for x and y using either of the above equations.

Step 1: Eliminating a negative and changing our operation

−2 1/6 + 1 3/4

Step 2: Rewriting our equation with parts separated

-2 − 1/6 + 1 + 3/4

Step 3: Solving the whole number parts

−2 + 1 = −1

Step 4: Solving the fraction parts

−1/6 + 3/4 = ?

Step 5: Find the LCD of 1/6 and 3/4 and rewrite to solve with the equivalent fractions.

When the pile is 22 feet high, the height of the pile changes to 20/1089π.

Given (dV)/(dt) = 20, h = 22 feet , dh /dt =?

The volume of cone is V = 1/3 * pi * r ^ 2 * h

d=3h

2r = 3h

r = (3h)/2

V = 1/3 * pi * r ^ 2 * h

= 1/3 * pi * ((3h)/2) ^ 2 * h

= 1/3 * pi((9 * H ^ 2 )/4) * h

= (9pi)/12 * h ^ 3

Differentiate w.r.to t

(dV)/(dt) = (3pi)/4 * (3h * h^ 2) * (dh)/(dt)

(dV)/(dt) = (9pi)/4 * (h ^ 2) * (dh)/(dt)

(dV)/(dt)=20, h=22 feet

20 = (9pi)/4 * (22 ^ 2) * (dh)/(dt)

(dh)/(dt) = 80/ (9pi * (22^ 2))

h^ t = 20/ 1089 *pi   ft / min
