First let's solve for the rate, "b", by setting up a ratio with the two points given:

16.875/7.5=(ar^3)/(ar)

2.25=r^2

r=1.5

Now we need to solve for the initial value a using either point given...

7.5=a(1.5)^1

7.5=1.5a

a=5

So now we have solved for both variables and have a complete equation:

y=5(1.5)^x

5.39 jings =15.4 hings

Dima020 [189]

Step-by-step explanation:

It is given that,

5.39 jings =15.4 hings ....(1)

4.9 hings = 2.8 gings ...(2)

From equation (2), the value of 1 ging is :

$1\ \text{ging} = \dfrac{4.9}{2.8}\ \text{hing}\ .....(3)$

From equation (1), the value of 1 jing is :

$1\ \text{jing} = \dfrac{15.4}{5.39}\ \text{hing}\ .....(4)$

From equation (3) and (4), we get :

$\dfrac{\text{1 ging}}{\text{1 jing}}=\dfrac{4.9}{2.8}\times \dfrac{5.39}{15.4}\\\\\dfrac{\text{1 ging}}{\text{1 jing}}=\dfrac{49}{80} \\\\1\ \text{ging}=\dfrac{49}{80}\ \text{ jings}$

Hence, the correct option is (g) "49/80"

Can some one help me if your good at geometry?

Shkiper50 [21]

Answer:

<h2><u> $x = 15 ft.$ </u></h2>

Step-by-step explanation:

Using Pythagoras Theorem:

$x^{2} + 8^{2} = 17^{2}$

⇒ $x^{2} = 17^{2} - 8^{2}$

⇒ $x = \sqrt{(17^{2} - 8^{2})}$

⇒ $x = \sqrt{(289 - 64)}$

⇒ $x = \sqrt{(225)}$

⇒ $x = 15 ft.$

A moterboat that ravels with a speen of 20km/hour in still water has traveld 20 km against the current and 180km with the curren

Ira Lisetskai [31]

Answer:

10 kph

Step-by-step explanation:

Find the speed of the current of the river.

20/(20 - c) + 180/(20 + c) = 8

20(20 + c) + 180(20 - c) = 8(400 - c^2)

8c^2 - 160c + 800 = 0

8(c^2 - 20c + 100) = 0

8(c - 10)^2 = 0

c = 10

The speed of the current of the river is 10 km/hour.

erica [24]

D. X/4=18/6

Step-by-step explanation:

Let x be the number of logs=18 hours

6 logs=4 hours

X*4=18*6

4x=108

x=27 logs

so therefore 27 logs are needed to keep the fire burning for 18 hours
