Helga [31]

Answer:

C

Step-by-step explanation:

This is a compound growth problem which is governed by the formula shown below:

F=P(1+r)^t

Where

F is the future amount (we want to find this)

P is the present amount (which is 75,000)

r is the rate of increase, in decimal (this is 2.2% or 2.2/100 = 0.022)

t is the time in years (which is 11 years)

Substituting the known values, we find F, the amount it is worth after 11 years:

F=P(1+r)^t\\F=75,000(1+0.022)^{11}\\F=75,000(1.022)^{11}\\F=95,284

Rounding to nearest hundred, that will be $95,300

Answer choice C is right.

Galina-37 [17]

The correct answers are:

- Wage/salary;

- Active job seekers;

The amount of money you earn by working is your wage or salary. The difference being that the wage represents the money you get paid on hourly, weekly, or monthly basis, while the salary is what you earn in year. The wages/salaries vary a lot, some being very high, some being modest, some very high, depending on the type of job, type of economy, as well as the qualifications of the worker.

The percentage of people that are actively looking for job is called active job seekers. The active job seekers can be people that are unemployed, but also people that re employed but want to work something or somewhere else. While some people struggle to find jobs and would accept almost anything, other people want to constantly progress, thus they are not satisfying with a job where they do not progress, so they seek for new challenges and opportunities.

Find the value of the lesser root of x^2 + 12x + 35 = 0.
morpeh [17]

Answer:

x = - 7

Step-by-step explanation:

Given

x² + 12x + 35 = 0

Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (+ 12)

The factors are + 7 and + 5, since

7 × 5 = 35 and 7 + 5 = 12, thus

x² + 12x + 35 = 0

(x + 7)(x + 5) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 5 = 0 ⇒ x = - 5

Thus the lesser root is x = - 7
