The projected annual percent growth is 11% and the worth in 2005 will be $566.92 million. The solution has been obtained by using linear equation.

What is a linear equation?

The degree of the linear equation is 1. It is clear that in linear equations with exponents greater than one, there are no variables. The equation for this graph produces a straight line.

We are given an equation as y = \(246(1.11)^{x}\)

From this, we get the percentage of annual growth as

⇒ (1.11 - 1) * 100

⇒ 0.11 * 100

⇒ 11%

The worth of company in 2005 is given by

y = \(246(1.11)^{x}\), where x = 8

On substituting, we get

⇒ y = \(246(1.11)^{8}\)

⇒ y = $566.92 million

Hence, the projected annual percent growth is 11% and the worth in 2005 will be $566.92 million.

The mixed numbers that have 12 as the LCD are 2 11/12 and 6 4/5. All other fractions do not have 12 as the denominator and are not equivalent.

Mixed numbers consist of a whole number and a fractional part. To add or subtract mixed numbers, the fractions must have the same denominator (the bottom number of the fraction).

The LCD (lowest common denominator) is the smallest number that all of the denominators can be divided into evenly. In this case, the LCD is 12.

2 11/12 and 6 4/5 both have 12 as the denominator. The denominator of 11/12 can be divided by 11 and 12, so it is the same as 12/12. The denominator of 4/5 can be divided by 4 and 12, so it is the same as 48/12 (4 x 12 = 48). Therefore, both fractions have the same denominator.

The other fractions do not have 12 as their denominator. 3 1/7 can be divided by 3, 7, and 12, so it is the same as 21/12 (3 x 7 = 21). 5 3/4 can be divided by 4, 5, and 12, so it is the same as 60/12 (4 x 5 = 60). 8 38/47 can be divided by 8, 47, and 12, so it is the same as 376/12 (8 x 47 = 376). Since none of these fractions are equal to 12/12, they are not equivalent to the other two fractions.

3      2

4      3

5      1

6     2

7     3

Start by calculating the mean using:

\(\bar x= \frac{\sum fx}{\sum f}\)

So, we have:

\(\bar x= \frac{1 * 1 + 2 * 2 + 2 * 3 + 3 * 4 + 1 * 5 + 2 * 6 + 3 *7 + 1 * 8}{1 +2+2+3+1+2+3+1}\)

Evaluate the sum and products

\(\bar x= \frac{69}{15}\)

Divide

\(\bar x= 4.6\)

The mean absolute deviation is then calculated as:

\(|\bar x| = \frac{\sum f|x - \bar x|}{\sum f}\)

So, we have:

\(|\bar x|= \frac{1 * |1 -4.6|+ 2 * |2 -4.6| + 2 * |3 -4.6|+ 3 * |4 -4.6|+ 1 *| 5 -4.6|+ 2 * |6 -4.6|+ 3 *|7 -4.6|+ 1 * |8-4.6|}{1 +2+2+3+1+2+3+1}\)

Evaluate the absolute difference

\(|\bar x|= \frac{1 * 3.6+ 2 * 2.6 + 2 * 1.6+ 3 * 0.6+ 1 *0.4+ 2 * 1.4+ 3 *2.4+ 1 * 3.4}{15}\)

Answer:

4p+3≥40

Step-by-step explanation:

The surface consisting of all points p for which the distance from p to the x-axis is 3 times the distance from p to the yz-plane.

The equation for the surface consisting of all points p for which the distance from p to the x-axis is 3 times the distance from p to the yz-plane is given by -

x = 3y2 + 3z2

To explain this equation, let us consider a point P(x, y, z) on the surface. The distance from this point P to the x-axis is given by |x|, and the distance from P to the yz-plane is given by √y2 + z2.

Now, the given condition states that the distance from P to the x-axis is 3 times the distance from P to the yz-plane. This can be written as |x| = 3√y2 + z2. By squaring both sides, we get x2 = 9(y2 + z2), which can be rearranged to give the equation x = 3y2 + 3z2.

This equation thus gives the surface consisting of all points p for which the distance from p to the x-axis is 3 times the distance from p to the yz-plane.

Answer:

\(\boxed {\boxed {\sf 682}}\)

Step-by-step explanation:

The nth term of an arithmetic sequence can be found using the following formula.

\(a_n=a+d(n-1)\)

where a is the first term, d is the common difference, and n is the term.

First, we should find the common difference.

We can do this by subtracting each term from the term following it. Basically, subtract the first term from the second term, the second from the third, and so on.

\(d= a_2-a_1\)

The second term is 25 and the first is 16.

\(d= 25-16\)

\(d=9\)

Now we know the common difference is 9. We also know the first term is 16 and we are looking for the 75th term.

\(d=9 \\a=16 \\n= 75\)

Substitute the values into the formula.

\(a_{75}=16+9(75-1)\)

Solve according the PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).

Solve the parentheses first.

\(a_{75}=16+9(74)\)

Multiply next.

\(a_{75}=16+666\)

Finally, add.

\(a_{75}=682\)

The 75th term in the sequence is 682.

The linear and exponential equations for the amount of money in the banks indicates;

TCF Bank Equation

y = 100·x + 1000

Well Fargo Bank Equation

y = (1.06)ˣ

The number of years it will take for both accounts to have the same amount of money is about 17 years

An exponential equation is an equation of the form; y = a·bˣ, where the input variable, x is an exponent.

The equation for calculating the amount in each bank, based on the details are;

TCF Bank;

Amount invested = $1,000

Amount added each year = 100·x

Well Fargo Bank Equation

The percentage of the amount earned as interest each year = 6% = 0.06

The exponential equation for compound interest amount is; y = 1000·(1 + 0.06)ˣ

Therefore; y = 1000·(1.06)ˣ

When the amount in the two accounts have the same amount of money, we get;

1000·(1.06)ˣ = 100·x + 1000

Therefore; (1.06)ˣ = (100·x + 1000)/1000 = 0.1·x + 1

(1.06)ˣ = 0.1·x + 1

Solving the above equation using the substitution method and graphing indicates that we get;

x = 0, and x ≈ 17.125732

Therefore, it takes about 17 years for the two accounts to have the same amount of money

1. 10% of the bill is $138. The final bill once 10% is taken off is $1242.

2. 20% of the total is $34.10. The final total once the 20% is taken off is $136.4

Step-by-step explanation:

1. A crash repair bill comes to $1380.00. How much is 10% of the bill? What is the final bill once 10% is taken off?

To find how much is 10% of the bill, we multiply the bill by 0.1

0.1*1380 = 138

10% of the bill is $138.

To find the final bill, we subtract the initial bill by 10%.

1380 - 138 = 1242

The final bill once 10% is taken off is $1242.

2. A person buys a new fan belt, a new alternator, and a new water pump for their car. The total comes to $170.50. What is 20% of the total? How much is the final total once the 20% is taken off?

Same logic as above.

0.2*170.50 = 34.1

20% of the total is $34.10.

170.50 - 34.1 = 136.4

The final total once the 20% is taken off is $136.4

A house and renting depends on your unique circumstances and priorities. These factors and consider consulting with a financial advisor or real estate professional  provide personalized guidance based on your situation.

Deciding whether buying a house is better than renting depends on various factors, including your personal circumstances, financial situation, and long-term goals. Here are some considerations to help you evaluate the decision:

Financial Stability: Buying a house typically involves a significant upfront cost, including down payment, closing costs, and ongoing expenses like mortgage payments, property taxes, and maintenance. Ensure you have a stable income and sufficient savings to handle these financial obligations.

Long-Term Plans: If you plan to settle in a specific location for an extended period, buying a house can provide stability and potential appreciation in value. Renting, on the other hand, offers more flexibility if you anticipate changes in your job, family, or lifestyle that may require relocation.

Market Conditions: Assess the local housing market to determine if it favors buyers or renters. Consider factors such as property prices, mortgage interest rates, and rental costs. In some markets, renting may be more affordable than buying, while in others, buying could be a better investment.

Lifestyle and Preferences: Owning a home grants you the freedom to personalize and modify the property to suit your needs. Renting often comes with limitations on making changes. Consider whether homeownership aligns with your lifestyle and if you prefer the responsibilities and benefits of homeownership.

Equity and Investment: Buying a house allows you to build equity over time as you pay down your mortgage, potentially providing a valuable asset in the future. Renting, however, does not offer this opportunity for equity growth.

Maintenance and Upkeep: Homeownership comes with the responsibility of maintenance and repairs, which can incur additional costs and effort. Renting typically shifts these responsibilities to the landlord or property management.
