What is the value of x when the Richter scale rating is 3.1

Answer:

To calculate the book value of the building, we need to calculate the annual depreciation amount and multiply it by the number of years elapsed since the building was completed.

The annual depreciation amount is calculated as: $1 million / 50 years = $20,000

In 2014, the book value of the building was: $1 million - ($20,000 * (2014 - 2010)) = $1 million - ($20,000 * 4) = $960,000

In 2022, the book value of the building will be: $1 million - ($20,000 * (2022 - 2010)) = $1 million - ($20,000 * 12) = $680,000

Answer:

g(3) = 11

g(-3) = 16

g(-1) =3

Step-by-step explanation:

For g(3)

g(x)= x² +2

g(3) = 3² + 2

g(3) = 9+2

g(3) = 11

For g(-3)

g(x) = -3x + 7

g(-3) = -3(-3) + 7

g(-3) = 9 + 7

g(-3) = 16

For g(-1)

g(x) = x² + 2

g(-1) = (-1)² +2

g(-1) = 1+2

g(-1) =3

Answer:

888.4 mL.

Step-by-step explanation:

To solve this problem, we can use the following formula:

Amount of drug (in mg) = concentration (in mg/mL) × volume (in mL)

We are given the concentration of the drug as 5.315 mg per 3.743 mL. To find the volume of the drug needed to give 4.719 g, we need to rearrange the formula to solve for volume:

Volume (in mL) = amount of drug (in mg) ÷ concentration (in mg/mL)

First, we need to convert 4.719 g to mg by multiplying by 1000:

4.719 g × 1000 mg/g = 4719 mg

Now we can substitute the given concentration and the calculated amount of drug into the formula and solve for volume:

Volume (in mL) = 4719 mg ÷ 5.315 mg/mL

Volume (in mL) ≈ 888.5 mL

Therefore, approximately 888.5 mL of the drug are needed to give 4.719 g. Rounded to 1 decimal, the answer is 888.4 mL.

Answer:

You can multiply the numerator and denominator by the same number.

For example, 1x2/4x2=2/8 which is equal to 1/4.

The probability of observing heads when tossing either coin is P(h) = 0.5*P(f) + 0.6*P(b), and the probability of observing tails is P(t) = 0.5*P(f) + 0.4*P(b).

Let's denote the probability of observing heads when tossing the fair coin as P(h|f) and the probability of observing tails when tossing the fair coin as P(t|f). Similarly, we can denote the probability of observing heads when tossing the biased coin as P(h|b) and the probability of observing tails when tossing the biased coin as P(t|b).

In this experiment, the probability of tossing the fair coin is P(f) and the probability of tossing the biased coin is P(b). We can calculate the probability of observing heads as:

P(h) = P(h|f)*P(f) + P(h|b)*P(b)

= 0.5*P(f) + 0.6*P(b).

Similarly, the probability of observing tails is:

P(t) = P(t|f)*P(f) + P(t|b)*P(b)

= 0.5*P(f) + 0.4*P(b).

The probability of observing heads when tossing either coin is P(h) = 0.5*P(f) + 0.6*P(b), and the probability of observing tails is P(t) = 0.5*P(f) + 0.4*P(b).

The solutions to the system of equations are x = 2 and 4

From the question, we have the following parameters that can be used in our computation:

f(x) = x - 3

g(x) = 1/(x - 3)

The solution to the system of equations implies that

f(x) = g(x)

So, we have

x - 3 = 1/(x - 3)

Cross multiply the equation

This gives

(x - 3)² = 1

So, we have

x - 3 = ±1

Add 3 to both sides

x = 3 ± 1

So, we have

x = 2 and 4

Hence, the solutions to the system of equations are x = 2 and 4

After 18 years, the investment compounded periodically (quarterly) will be worth $1,230.23 more than the investment compounded annually.

Compounded interest refers to the interest system that charges interest on both principal and accumulated interest.

The period of compounding in a year determines the worth of the future value.

The future value can be ascertained using an online finance calculator as follows:

Interest periods: = 4 times yearly (Quarterly)

Principal = $5,000

Annual interest rate = 9%

Number of years: 18

N (# of periods) = 72 quarters (18 years x 4)

I/Y (Interest per year) = 9%

PV (Present Value) = $5,000

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $24,815.83

Total Interest = $19,815.83

Interest periods: = Annually

N (# of periods) = 18 years

I/Y (Interest per year) = 9%

PV (Present Value) = $5,000

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $23,585.60

Total Interest = $18,585.60

Difference in Future Values $1,230.23 ($24,815.83 - $23,585.60)

Polynomials are classified according to their number of terms. 4x3 +3y + 3x2 has three terms, -12zy has 1 term, and 15 - x2 has two terms. As already mentioned, a polynomial with 1 term is a monomial. A polynomial with two terms is a binomial, and a polynomial with three terms is a trinomial

Step-by-step explanation:

The polynomial -10x is a first-degree polynomial and consists of one term.

The polynomial -10x can be named based on its degree and number of terms.

Degree: The degree of a polynomial is determined by the highest exponent of the variable in the expression. In this case, the highest exponent of the variable 'x' is 1. Since there is no 'x^2', 'x^3', or any higher power of 'x', the degree of the polynomial is 1.

Number of terms: The number of terms in a polynomial is determined by how many separate expressions are added or subtracted together. In -10x, there is only one term, which is -10x.

So, we can name the polynomial -10x as:

Degree: 1 (since the highest exponent of 'x' is 1)

Number of terms: 1 (since there is only one term)

In summary, the polynomial -10x is a first-degree polynomial and consists of one term. It does not have any constant term (a term with no 'x') and contains only the term -10x, which has a coefficient of -10 and a variable of 'x'.
