Step-by-step explanation:
The equation that represents this relationship will be y = 2u³.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
The value of y varies directly as the cube of u. y = 54 when u = 3.
y ∝ u³
Removed the proportionality constant and place the equal sign with constant k.
y = ku³
Put y = 54 when u = 3, then the value of k will be
54 = k (3)³
54 = 27k
k = 2
Then the equation that represents this relationship will be
y = 2u³
The equation that represents this relationship will be y = 2u³.

A snail crawled 7 miles in 8.4 hours. At this speed, how long would it take the snail to crawl 10 miles?
Answer: 12 hours
Step-by-step explanation:
Let's set the speed as "s".
Remember that distance = speed * time
So, plugging the numbers given...
7 = s * 8.4
Divide both sides by 8.4
s = 5/6
Now, plug this into the distance = speed * time, with the distance being 10. Set the time as "t"
10 = 5/6 * t
Divide both sides by 5/6
12 = t
So, it would take 12 hours for the snail to crawl 10 miles.

Answer:
X=9
Step-by-step explanation:
2(9)-5 > 11
18-5 > 11
13>11
2x-5>11
2x-5+5>11+5 five will be cancelled five
2x>11+5
2x>16 divide 2 by 2 you get x then divide 16 by 2
x>8 this means x is greater than eight {x= 9,10,11,12.......}

pls no links. my computer can't open
Answer:
[tex](x-7)^2+(y-1)^2=100[/tex]
Step-by-step explanation:
1) Find the radius
We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (7,1) and (-1,-5)
[tex]d=\sqrt{(-1-7)^2+(-5-1)^2}\\d=\sqrt{(-8)^2+(-6)^2}\\d=\sqrt{64+36}\\d=\sqrt{100}\\d=10[/tex]
Therefore, the radius of the circle is 10 units.
2) Plug the data into the equation of a circle
Equation of a circle (when not centred at the origin):
[tex](x-h)^2+(y-k)^2=r^2[/tex] where the centre is [tex](h,k)[/tex] and r is the radius
Plug in the centre (7,1) as (h,k)
[tex](x-7)^2+(y-1)^2=r^2[/tex]
Plug in the radius 10
[tex](x-7)^2+(y-1)^2=10^2\\(x-7)^2+(y-1)^2=100[/tex]

Answer:
x>-8 (Or option D)
Step-by-step explanation:
-2x+7<23 Subtract 7 from both sides
-2x<16 Now divide by -2. You also have to flip the < sign because you are dividing by a negative number
x>-8
The reasoning for D over C is because D is an open circle meaning that it is only less than or greater than. When it is a closed circle, it means less than or equal to or greater than or equal to. :)

A train moving at 40km/h applies brakes so that there is a constant 0.5m/s².find the time taken before the train stops.
Answer:
t = 22.22 s
Step-by-step explanation:
Given that,
The initial speed of the train, u = 40 km/h
Acceleration of the train, a = 0.5 m/s²
Finally, it stops, v = 0
We need to find the time taken by it to stop. using first equation of motion to find it such that,
[tex]v=u+at\\\\t=\dfrac{v-u}{a}\\\\t=\dfrac{0-40\times \dfrac{5}{18}}{-0.5}\\\\t=22.22\ s[/tex]
So, it will take 22.22 seconds to stop.
