Answer:

Nina can run:

13 1/2 km in 1 hour

Step-by-step explanation:

4 1/2 = 4 + 1/2 = 8/2 + 1/2 = 9/2

proportions:

9/2 hours ⇔  1/3 hour

N hours ⇔ 1 hour

N = (9/2)*1 / (1/3)

N = (9/2) / (1/3)

N = (9*3) / (2*1)

N = 27/2

27/2 = 26/2 + 1/2 = 13 + 1/2 = 13 1/2

Nina can run:

13 1/2 km/h

A bounded sequence is convergent.

A) Since Sequence means its range st is bounded then it's lower bound and upper bound exist.

Ler v be an upper bound of sequence then,

B) Let {\(a_{n}\)} be a sequence,

Since \(a_{n}\) goes to l, for all ε >0

The total amount accrued, principal plus interest, with compound interest on a principal of $3,000.00 at a rate of 6% per year compounded 1 times per year over 3 years is $3,573.05.

Given Data

A = P + I where

P (principal) = $3,000.00

I (interest) = $573.05

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 3,000.00(1 + 0.06/1)^(1)(3)

A = 3,000.00(1 + 0.06)^(3)

A = $3,573.05

Scott's analysis of the impact of trade deficits on American jobs fails to consider the macroeconomic effects of trade deficits on domestic employment.

Irwin argues that Scott's analysis is incomplete as it ignores the long-term impact of trade deficits on employment. Scott's analysis is limited to looking at the short-term effect of trade deficits on the number of jobs lost or gained in certain industries.

He argues that trade deficits do not necessarily lead to a net loss of jobs in the economy, as the money saved by consumers through lower prices can be spent elsewhere, creating new jobs in other sectors.

However, Irwin argues that this analysis misses the bigger picture. Irwin suggests that trade deficits can lead to a long-term decline in the manufacturing sector, which can have significant negative consequences for domestic employment. Trade deficits can lead to a decrease in demand for domestically produced goods, as foreign competitors offer lower-priced alternatives. This can lead to a reduction in domestic production and employment in the affected industries.

Furthermore, Irwin argues that trade deficits can have a negative impact on the economy as a whole. Trade deficits can lead to a decrease in the value of the dollar, which can increase inflation and reduce consumer purchasing power. This, in turn, can lead to a decrease in demand for goods and services, which can negatively impact employment across multiple sectors.

In conclusion, Scott's analysis of the impact of trade deficits on American jobs is incomplete, as it fails to consider the long-term macroeconomic effects of trade deficits on domestic employment. Irwin argues that a full accounting of the impact of trade deficits on American jobs must take into account the potential negative consequences on the manufacturing sector and the economy as a whole.

The vector function r'(t), r"(t), r'(t) r"(t), and r'(t) x r"(t). is
(a) r'(t) = 3ti - 3j + 15t²k

(b) r"(t) = 3i + 15tk

(c) r'(t) · r"(t) = 9t - 45t²

(d) r'(t) x r"(t) = -90t²i - 45tj - 9k

To find the derivatives of the vector function r(t) = 3²³i - 3tj + 5t³k, we differentiate each component of the vector with respect to t.

(a) To find r'(t), we differentiate each component separately:

r'(t) = (d/dt)(3²³i) - (d/dt)(3tj) + (d/dt)(5t³k)

= 0i - 3j + 15t²k

= 3ti - 3j + 15t²k

(b) To find r"(t), we differentiate each component of r'(t) with respect to t:

r"(t) = (d/dt)(3ti) - (d/dt)(3j) + (d/dt)(15t²k)

= 3i + 0j + 15tk

= 3i + 15tk

(c) To find r'(t) · r"(t), we take the dot product of r'(t) and r"(t):

r'(t) · r"(t) = (3ti - 3j + 15t²k) · (3i + 15tk)

= 9t - 45t²

(d) To find r'(t) x r"(t), we take the cross product of r'(t) and r"(t):

r'(t) x r"(t) = (3ti - 3j + 15t²k) x (3i + 15tk)

= -90t²i - 45tj - 9k

In summary, r'(t) = 3ti - 3j + 15t²k, r"(t) = 3i + 15tk, r'(t) · r"(t) = 9t - 45t², and r'(t) x r"(t) = -90t²i - 45tj - 9k.

Based on the AA Similarity Theorem, triangles PQR and TSR are proven to be similar to each other because they have two pairs of corresponding angles that are congruent to each other.

The AA (Angle-Angle) Similarity Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This means that the corresponding sides of the triangles are in proportion to each other.

The root of the equation sinx = 2x-3 is 0.8401 (approx).

Given equation is sinx = 2x-3

We need to solve this equation using false position method.

False position method is also known as the regula falsi method.

It is an iterative method used to solve nonlinear equations.

The method is based on the intermediate value theorem.

False position method is a modified version of the bisection method.

The following steps are followed to solve the given equation using the false position method:

1. We will take the end points of the interval a and b in such a way that f(a) and f(b) have opposite signs.

Here, f(x) = sinx - 2x + 3.

2. Calculate the value of c using the following formula: c = [(a*f(b)) - (b*f(a))] / (f(b) - f(a))

3. Evaluate the function at point c and find the sign of f(c).

4. If f(c) is positive, then the root lies between a and c. So, we replace b with c. If f(c) is negative, then the root lies between c and b. So, we replace a with c.

5. Repeat the steps 2 to 4 until we obtain the required accuracy.

Let's solve the given equation using the false position method.

We will take a = 0 and b = 1 because f(0) = 3 and f(1) = -0.1585 have opposite signs.

So, the root lies between 0 and 1.

The calculation is shown in the attached image below.

Therefore, the root of the equation sinx = 2x-3 is 0.8401 (approx).

Answer and Step-by-step explanation: Area of a right triangle, (as any other triangle), is calculated as:  \(A1=\frac{(base)(height)}{2}\)

Area of a rectangle is calculated as: \(A2=(side)(side)\)

Area of a right trapezoid is: \(A3=\frac{(a+b)h}{2}\), where:

a is short base

b is long base

h is height

1) Expressing areas in terms of x:

Area of triangle S1:

\(S1=\frac{(2x-3)(4x-6)}{2}\)

\(S1=4x^{2}-12x+9\)

Area of rectangle S2:

\(S2 = (4x-6)(3x-2)\)

\(S2=12x^{2}-26x+12\)

Area of trapezoid S3:

\(S3=\frac{(2x+3+4x+1)(2x-3)}{2}\)

\(S3=\frac{(6x+4)(2x-3)}{2}\)

\(S3=6x^{2}-5x-6\)

2) a) \(S=4x^{2}-12x+9+12x^{2}-26x+12-(6x^{2}-5x-6)\)

\(S=4x^{2}-12x+9+12x^{2}-26x+12-6x^{2}+5x+6\)

\(S=10x^{2}-33x+37\)

Which is the same as S = (2x-3)(5x-9)

b) For the areas to be the same:

\(\frac{(3x-2+3x-2+2x-3)(4x-6)}{2}=\frac{(6x+4)(2x-3)}{2}\)

\(\frac{(8x-7)(4x-6)}{2}=\frac{(6x+4)(2x-3)}{2}\)

\(32x^{2}-48x-28x+42=12x^{2}+8x-18x-12\)

\(20x^{2}-66x+54=0\)

Using Bhaskara to solve the second degree equation:

\(\frac{66+\sqrt{(-66)^{2}-(4.20.54)} }{2(20)}\)

\(x_{1}=\frac{66+6}{40}\) = 1.8

\(x_{2}=\frac{66-6}{40}\) = 1.5

For the areas of AFGC and ADEB to be equal, x has to be 1.5 or 1.8.

c) Expand a polynomial (or equation) is to multiply all the terms, remiving the parenthesis. Reduce a polynomial (or equation) is to combine terms alike,e.g.:

\(S=(2x-3)(5x-9)\)

\(S=10x^{2}-18x-15x+27\) (expand)

\(S=10x^{2}-33x+27\) (reduce)

d) For area of AFCG to be bigger than area of ADEB by 27:

\(32x^{2}-48x-28x+42=12x^{2}+8x-18x-12+27\)

\(32x^{2}-48x-28x+42=12x^{2}+8x-18x+15\)

\(20x^{2}-66x+27=0\)

Solving:

\(\frac{66+\sqrt{(-66)^{2}-(4.20.27)} }{2(20)}\)

\(\frac{66+46.86}{40}\)

\(x_{1}=\frac{66+46.86}{40}=\) 2.82

\(x_{2}=\frac{66-46.86}{40}\) = 0.48

According to the enunciation, x cannot be less than 1.5, then, the value of x so that area AFGC exceeds the area ADEB by 27 is 2.82

The cost of one yard of green fabric is $10.

Let's assume that the cost of one yard of green fabric is represented by the variable x. Since the blue fabric costs $3 more per yard, the cost of one yard of blue fabric can be expressed as (x + $3).

La Tanya buys 4 yards of blue fabric, so the total cost of the blue fabric is 4(x + $3). She also buys 7 yards of green fabric, so the total cost of the green fabric is 7x.

The total cost of the fabrics is given as $122, so we can set up the equation:

4(x + $3) + 7x = $122

Simplifying the equation:

4x + $12 + 7x = $122

11x + $12 = $122

11x = $122 - $12

11x = $110

Dividing both sides by 11:

x = $110 / 11

x = $10

Therefore, the cost of one yard of green fabric is $10.
