How many times greater is the population of china than the population of france? write your answer in standard notation

bezimeni [28]

In Scientific Notation:
China's current population is 1,355,692,544 while France only has 66,259,012. China has 1.29x10⁹ more people than the latter has. China is 0.20x10⁻² times greater in terms of population than France.

In Mathematical sentence:
China has over 1,289,433,532 people than France.
It is 20.46050044 times greater in population than France.

Answer:

The vertex form of a quadratic function:

(h,k) - the coordinates of the vertex

If a>0, then the parabola opens upwards, so the vertex is the minimum of the function.

If a<0, then the parabola opens downwards, so the vertex is the maximum of the function.

Really could use help here.

Answer:

$\mathsf {y =\frac{15}{7}x }$ < $\mathsf {y=\frac{13}{6}x }$ < $\mathsf {y=\frac{11}{5}x }$ < $\mathsf {y=\frac{21}{9}x }$ < $\mathsf {y= \frac{19}{8}x}$

Step-by-step explanation:

Finding the unit rate of the graph :

Take 2 points and find the slope
⇒ (0,0) and (12, 25)
⇒ m = 25 - 0 / 12 - 0
⇒ m = 25/12
The equation is : y = 25/12x

Now, the equations with greater unit rates (in increasing order) are :

$\mathsf {y =\frac{15}{7}x }$ < $\mathsf {y=\frac{13}{6}x }$ < $\mathsf {y=\frac{11}{5}x }$ < $\mathsf {y=\frac{21}{9}x }$ < $\mathsf {y= \frac{19}{8}x}$

change the mixed numbers to improper fractions before dividing

1 $\frac{1}{4}$ = $\frac{5}{4}$ and 15 $\frac{1}{3}$ = $\frac{46}{3}$
