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. ​

Answers

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.

6/5 > 5/6 = Yes

3/8 < 1/4 = No

What is a fraction

A fraction is defined as the part of a whole value which is represented as a numerator and a denominator form.

1/3 is greater than 1/6 because 1/3 = 0.3 which is greater than 1/6 = 0.2

4/3 is not greater than 8/6 because 4/3 = 1.3 which is equivalent to 8/6 = 1.3.

6/5 is greater than 5/6 because 6/5 = 1.2 which is greater than 5/6 = 0.8

3/8 is not less than 1/4 because 3/8 = 0.4 which is greater than 1/4 = 0.3.

Write the standard form of the equation of the circle with center (7,1) that also contains the point (−1,−5).

Enter the equation in simplest terms.
pls no links. my computer can't open

Answers

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]

I hope this helps!
