Otto's investment portfolio consisted of shares of internet stock and copper stock. During the year, the value of his internet shares increased $10\%$, but the value of his copper shares decreased from $\$10{,}000$ to $\$9{,}000$. During the same year, the total value of his portfolio increased by $6\%$. What was the dollar value of his internet shares at the end of the year?

Answers

Answer 1

Answer:

44000

Step-by-step explanation:

Let w be the initial value of Otto's internet stock, in dollars. At the beginning of the year, the total value of his portfolio is w+10,000 dollars. At the end of the year, the total value of his portfolio is 1.1w+9,000 dollars. Since increasing by 6% is equivalent to multiplying by 1.06, we have

1.06(w+10,000)=1.1w +9,000

Distributing and collecting terms, we find w=40,000. At the end of the year, his internet stock is worth 40,000* 1.1=44,000 dollars.

mrs jones attended a southern living Home party she purchased a vase which cost $34.99 The shipping charge was three dollars and 8.25% sale tax was paid on the subtotal which included the shipping charge how much did she pay for the vase

Answers

The total amount paid for vase is $ 41

Solution:

Given that

Cost of vase = $ 34.99

Shipping charge = 3 dollars

Sales tax = 8.25 % was paid on the subtotal which included the shipping charge

To find: total amount paid for vase

total amount paid for vase = Cost of vase + Shipping charge + sales tax

Let us first find the sales tax

Given that 8.25 % was paid on the subtotal which included the shipping charge

Subtotal = 34.99 + 3 = 37.99

So 8.25 % of 37.99 was paid as sales tax

[tex]\text{ sales tax } = \frac{8.25}{100} \times 37.99 = 3.1341[/tex]

Therefore sales tax amount paid = $ 3.1341

total amount paid for vase = Cost of vase + Shipping charge + sales tax

total amount paid for vase = 34.99 + 3 + 3.1341 = 41.1241 ≈ 41

Therefore total amount paid for vase is $ 41

A new pair if shoes will cost you $86 if you buy them on black friday. They will be dicounted 45%. How much will you save if you wait until black Friday

Answers

Answer:

saving amount=$38.7

Step-by-step explanation:

given cost price=$86

discount on black friday=45%

selling price=cost price(1-discount%)

selling price=86(1-[tex]\frac{45}{100}[/tex])

selling price=86([tex]\frac{55}{100}[/tex])

selling price=$47.3

saving amount=$86-$47.3=$38.7

saving amount=$38.7 answer

To find the savings on the shoes, multiply the original price by 45% to find the discount amount, then subtract it from the original price. The savings amount to $38.70.

You want to know how much you will save on a new pair of shoes that costs $86 if they are discounted by 45% on Black Friday. To calculate the savings, you need to calculate 45% of the original price and then subtract that amount from the original price.

Step-by-Step Calculation:

Calculate 45% of $86: (0.45 × $86 = $38.70).

Subtract the discount from the original price: ($86 - $38.70 = $47.30).

Therefore, if you wait until Black Friday, you will save $38.70 on the shoes.

Find the minimum or maximum value of f(x) = x2 + 6x +11 .

Answers

Answer:

Therefore the Minimum value of f(x) is 2.

Step-by-step explanation:

Given:

[tex]f(x)=x^{2} + 6x+11[/tex]

To Find:

minimum or maximum value of f(x)

Solution:

To find minimum or maximum value of f(x)

Step 1 . Find f'(x) and f"(x)

[tex]f(x)=x^{2} + 6x+11[/tex]

Applying Derivative on both the side we get

[tex]f'(x)=\dfrac{d(x^{2})}{dx}+\dfrac{d(6x)}{dx}+\dfrac{d(11)}{dx}[/tex]

[tex]f'(x)=2x+6+0[/tex]

Again Applying Derivative on both the side we get

[tex]f''(x)=\dfrac{d(2x)}{dx}+\dfrac{d(6)}{dx}[/tex]

[tex]f''(x)=2[/tex]

Step 2. For Maximum or Minimum f'(x) = 0 to find 'x'

[tex]2x+6=0\\\\2x=-6\\\\x=\dfrac{-6}{2}=-3[/tex]

Step 3. IF f"(x) > 0 then f(x) is f(x) is Minimum at x

            IFf"(x) < 0 then f(x) is f(x) is Maximum at x

Step 4. We have

[tex]f''(x)=2[/tex]

Which is grater than zero

then f(x) is Minimum at x= -3

Therefore the Minimum value of f(x) is 2.

The minimum value is 2 when x = -3.

The minimum or maximum value of the function f(x) = x^2 + 6x +11, we need to complete the square or use the vertex formula for a quadratic function.

The function is a parabola that opens upwards (since the coefficient of the x2 term is positive). To complete the square, we group the x-terms and add and subtract the square of half the coefficient of x:

f(x) = (x^2 + 6x + 9) + 11 - 9

f(x) = (x + 3)^2 + 2

The minimum value of this parabola occurs at the vertex, which is (-3, 2).

Solve 5n^2=5 with the quadratic formula

Answers

Answer:

n = 1

Step-by-step explanation:

First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.

5n² = 5

5n² - 5 = 0

State the variables a, b and c.

a = 5;  b = 0;  c = -5

Substitute a, b, and c into the quadratic formula.

[tex]n = \frac{-b ±\sqrt{b^{2}-4ac} }{2a}[/tex]

[tex]n = \frac{-0 ±\sqrt{0^{2}-4(5)(-5)} }{2(5)}[/tex]   Substitute

[tex]n = \frac{\sqrt{100} }{10}[/tex]   Simplify inside the √ and bottom

[tex]n = \frac{10}{10}[/tex]  Simplify the top

[tex]n = 1[/tex]  Final answer

Therefore the solution is n = 1.

The quadratic formula usually is written with x, but it can be solved with any variable in standard form.

The options 3, 4, and 5 are functions.

Step-by-step explanation:

If there is more than one value of y for a given single value of x then this is called a relation but not a function.

That geometrically means that if you can draw a vertical line that intersects the graph that is plotted from the given points that intersect the graph at more than one point then this graph is called a relation and not a function.

Here, in option one the points on the graph are given to be (6,-6), (-3,12), (6,-1) and (-8,13), which is not a function as there are two values of y for x = 6.

Now, in option two the points on the graph are given to be (0,0.5), (2,1), (1,2.5) and (0,2), which is also not a function as there are two values of y for x = 0.

Now, in option three the points on the graph are given to be (8,7), (7,8), (6,5) and (5,6). this can be a function.

Now, in option four the points on the graph are given to be (-2,7), (-3,9), (-5,9) and (-8,11). this can be a function.

15 people received an email and sent it to 3 different friends each, who in turn each sent it to 2 new people. What percent of the total number of people who received the e-mail are the original 15 people?

Answers

The original 15 people are 10% of the total number of people who received the mail.

Step-by-step explanation:

Given,

Number of people who received mail = 15

Mail further sent to 3 more friends;

Number of people who received mail from 15 people = 15*3 = 45 people

Number of people who received mail from 45 people = 45*2 = 90 people

Total number of people = 15+45+90 = 150 people

Now,

Percent of original people = [tex]\frac{Number\ of\ original\ people}{Total\ number\ of\ people}*100[/tex]

Percent of original people = [tex]\frac{15}{150}*100=10\%[/tex]

How many miles could Kenja travel in 1 hour. Is this the same number of hours it takes kenja to travel 1 mile? Explain your answer

Answers

Answer:

Kenja could travel a certain number of miles in 1 hour depending the speedometer. So, it is not necessary that she may always take the same number of hours it takes to travel 1 mile.

For example, If Kenja has traveled 120 miles in three hours. It means it would take 5 hours to travel 200 miles. The reason is that her unit rate is 40 miles per hour. So, it would take her 1/40 hours to travel one mile.

Step-by-step explanation:

Kenja could travel a certain number of miles in 1 hour depending the speedometer.

If she is traveling at the rate of 5 miles per hour, it would take her 12 minutes to travel one mile. The only way she can take the same number of hours to travel 1 miles if she travels at the rate of 1 mile per hour.

For example, if Kenja has traveled 120 miles in three hours. It means it would take 5 hours to travel 200 miles. The reason is that her unit rate is 40 miles per hour.

As

[tex]\frac{120}{3} = 40 mph[/tex]  

So, if the unit rate is 40 mph, then it would take her 1/40 hours to travel one mile.

So, it is not necessary that she may always take the same number of hours it takes to travel 1 mile.

If the two machines work at the same time, they can print 200 T-shirts in
minutes.

Answers

Answer:

They will work together and print 200 T-shirts in 37.5 minutes.

Step-by-step explanation:

One machine can print 200 T-shirts in 50 minutes.

So, in one minute that machine can print [tex]\frac{200}{50} = 4[/tex] T-shirts.

Again, the other machine can print 200 T-shirts in 150 minutes.

So, in one minute the other machine can print [tex]\frac{200}{150} = 1.33[/tex] T-shirts.

Therefore, working together for one minute both the machines will print (4 + 1.33) = 5.33 number of T-shirts.

Hence, they will work together and print 200 T-shirts in [tex]\frac{200}{5.33} = 37.5[/tex] minutes. (Answer)

Answer:
37.5 Minutes
Step-by-step explanation:

1. I set up the fourmula: 1/50 + 1/150 = 1/x

2. I rewrote the fractions with a denominator which was 750 in this case: 50/750 + 150/750 = 1/x

3. I added the numerators: 200/750 = 1/x

4. I took the reciprocal of both sides of the equation: 750/200 = x/1

5. I wrote the result as a decimal number: 3.75 ≈ 37.5 minutes.

So, they can print 200 T-shirts in 37.5 minutes.

If f(n) = (2n + 3)2 – 2n, which statement is true?

2. f(2)= 619
3. f(5) = 16
4. f(-4)= -3

Answers

Final answer:

Upon evaluating the function f(n) = (2n + 3)2 – 2n at the given values, the true statement is f(3) = 75.

Explanation:

To determine which statement about the function f(n) = (2n + 3)2 – 2n is true, we must evaluate the function at the given values of n.

For f(3), we calculate (2·3 + 3)2 – 2·3 = (6 + 3)2 – 6 = 92 – 6 = 81 – 6 = 75.For f(2), we calculate (2·2 + 3)2 – 2·2 = (4 + 3)2 – 4 = 72 – 4 = 49 – 4 = 45, not 619.For f(5), we calculate (2·5 + 3)2 – 2·5 = (10 + 3)2 – 10 = 132 – 10 = 169 – 10 = 159, not 16.For f(-4), we calculate (2·(-4) + 3)2 – 2·(-4) = (-8 + 3)2 – (-8) = (-5)2 – (-8) = 25 + 8 = 33, not -3.

Therefore, the statement that is true is f(3) = 75.

In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to write

The terms are ordered from biggest exponent to lowest exponent

In the given equation,

[tex]6x^5 + 8x - 3x^3 + 7x^7[/tex]

7 is the highest exponent. So we write the standard form as,

[tex]7x^7 + 6x^5 -3x^3 + 8x[/tex]

Thus the terms are arranged from highest exponent to lowest exponent

The  standard form of the polynomial in 6x^5 + 8x-3x^3+7x^7 is

In mathematics, an expression is a combination of numbers, symbols, and/or operators that represents a mathematical phrase or statement. Expressions can consist of variables, constants, arithmetic operations (such as addition, subtraction, multiplication, and division), exponents, and functions.

To write a quadratic function f with zeros at -9 and -1, we use the fact that a quadratic function f(x) can be represented in the form f(x) = a(x - r1)(x - r2), where r1 and r2 are the zeros of the function and a is a nonzero coefficient. In this case, our zeros are -9 and -1, giving us f(x) = a(x + 9)(x + 1). To keep the function in simplest form, we can choose a = 1, which gives us the quadratic function f(x) = (x + 9)(x + 1) or f(x) = x2 + 10x + 9 after expanding the expression.

Final answer:

A quadratic function with zeros at -9 and -1 can be written as f(x) = (x + 9)(x + 1) or f(x) = x^2 + 10x + 9 when expanded.
