Answer:  472,750

Step-by-step explanation:

The population of the city                                       =   310,000

Yearly growing rate                                                 =    3.5%

Now find 3.5% of the population                             =    3.5  x  310,000

                                                                                        ----------------------

                                                                                                  100

                                                                                  =   10,850.

To find the population increase after 15 years       =   10850  x  15

                                                                                  =    162,750

Population in 15 years                                               =   310,000 + 162,750

                                                                                   =   472,750

Answer:

y= x - 300

y = -246 -- Her equivalent weight on earth

Step-by-step explanation:

Given

The attached table

Required

Fill in the gaps

(a) The equation

First, we calculate the slope (m)

m = \frac{y_2  - y_1}{x_2 - x_1}

From the table, we can say that:

(x_1,y_1) = (0,-300)

(x_2,y_2) = (300,0)

So, we have:

m = \frac{0  -(-300)}{300 - 0}

m = \frac{0 +300}{300}

m = \frac{300}{300}

m = 1

The equation is then calculated using:

y - y_1 = m(x - x_1)

This gives:

y - (-300) = 1(x - 0)

y +300 = 1(x)

y +300 = x

y= x - 300

(b) When x = 54

Substitute 54 for x in y= x - 300

y = 54 - 300

y = -246
