Solve the inequality −10 ≤ 2x - 4 < 8

Roman55 [17]

Answer:

- 3 is greater than or equal to x is greater than or equal to 6

Step-by-step explanation:

$- 10 \leq 2x - 4 \leq 8\\\\-10 + 4\leq 2x - 4 + 4\leq 8+4\\\\-6 \leq 2x \leq 12\\\\\\frac{-6}{2} \leq \frac{2x}{2} \leq \frac{12}{2} \\\\-3 \leq x \leq 6$

Hope this helps!!!!

Answer:

A = $5183.36

Step-by-step explanation:

Compound Interest

It occurs when the interest is reinvested rather than paying it out. Interest in the next period is then earned on the principal sum plus previously accumulated interest.

The formula is:

$A=P\left(1+{\frac {r}{n}}\right)^{nt}$

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Abdul deposited P=$4000 into an account with r=2.6% = 0.026 compounded quarterly. Since there are 4 quarters in a year, n=4. We are required to calculate the amount in the account after t=10 years.

Applying the formula:

$A=4000\left(1+{\frac {0.026}{4}}\right)^{4*10}$

$A=4000\left(1.0065\right)^{40}$

A = $5183.36

The population of Brazil was 162,300,000 in 1995. It was growing at a rate of about 2% per decade. Predict the population, to th

stiv31 [10]

Answer:

The population is 168,900,000 to the nearest hundred thousand

Step-by-step explanation:

In this question, we are tasked with calculating the population of Brazil given its population in 1995 and her growth rate per decade.

Mathematically, we use an exponential function to calculate this population.

This can be written as P = I(1 + r)^n

where P is the population in 2015 which we are looking for,

I is the initial population which is 162,300,000

r is the rate of increase per decade given as 2% = 2/100 = 0.02,

n is the number of times between the years we are expecting this growth. The difference between the years 2015 and 1995 is 20 years which signifies 2 decades(1 decade is 10 years). Thus our n is 2

We plug these values into the equation above;

P = 162,300,000(1+0.02)^2

P = 162,300,000(1.02)^2

P = 168,856,920 which is 168,900,000 to the nearest hundred thousand
