I just learned about this!

How to get Number 1: This closed circle represents it is more than or equal to 4. so it should be x ≥ 4.

How to get number 2: This circle is open which means it is NOT equal to or close to the number so it should be x≠-4. Because you don't know how much x is and the lines and arrows represent it is not equal.

Number 3: The first option is the correct one as it says clearly x is less than -3 so it should be a open circle.

Number 4: The 2nd one is right because x is less than -1 or equal to -1.

In 2010, a city's population was 1,405,233 and it was decreasing at a rate of 1.1%. At this rate when will the city's population
frez [133]
The equation
                                            P(t) = 1405233 * (1 - 0.011)^(t)
models the population at t years after 2010. Then, when P(t) = 1,200,000, we have
                                 1200000 = 1405233 * (0.989)^t
                                  (0.989)^t = 1200000/1405233
                                                t = log(1200000/1405233)/log(0.989)
                                                t = 14.27 years
This means 14.27 years after 2010. Therefore, the answer to this question is 2024.

Question 5
Mice21 [21]

Answer:

The missing value is 2

Step-by-step explanation:

A direct variation satisfies the equation y=kx.

Since the point (-18, 12) lies on this line, it must satisfy this equation.

\implies 12=-18k

k=-\frac{12}{18} =-\frac{2}{3}

Hence the equation of this line is y=-\frac{2}{3}x

Now we substitute x=-3 to find y.

y=-\frac{2}{3}*-3=2

Therefore the missing value is 2
