5. Two trains travel in the same direction on

Mathematics
1 answer:
Sedbober [7]2 years ago
6 0

If the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour then after 5 hours they will be in the same place.

Given that the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour.

We are required to find the time after which both the trains will be in same place.

Speed is basically the distance travelled in a particular time.

Speed=Distance/Time.

Because the difference between both the train A and train B is 10 kilometers per hour so train B will cover 50 kilometers in 5 hours.

They will be at same place after 5 hours.

Hence if the speed of train A is 90 kilometers per hour and the speed of train B is 100 kilometers per hour then after 5 hours they will be in the same place.

stepan [7]

Answer:

sin = \frac{\sqrt{5} }{3}

Step-by-step explanation:

                                             <u>SOH CAH TOA</u>

Where:

s = sin

c = cos

t = tan

o = opposite

a = adjacent

h = hypotenuse  

cos = 2/3 where 2 is adjacent side and 3 is hypotenuse, now find opposite side using a^2 + b^2 = c^2 //c is hypotenuse side

2^2 + b^2 = 3^2

4 + b^2 = 9

b^2 = 9 - 4

b^2 = 5

b = square root (5) = 5^(1/2) //opposite side

sin = O/H

sin = \frac{\sqrt{5} }{3}

//Hope it helps.

Notice that 6 = 4+2,

11=6+5

19 = 11+8

30 = 19+11

Following the same pattern,

(next number) = 30 + 14 = 44

44 is the next number in the sequence 4, 6, 11, 19, 30, ...

NEED HELP PLEASE!!!<br><br> Given f(x)=9x+4 and g(x)= -5x+1, what is g(x)-f(x)?
GenaCL600 [577]

Answer:

g(x) - f(x) = -14x - 3

Step-by-step explanation:

We need to subtract the function f(x) = 9x + 4 from the function g(x) = -5 + 1.  Rewriting these two functions in columns, we get

       g(x)= -5x+1

      - f(x) = -(9x+4)         Note:  Use parentheses as shown here.

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

g(x) - f(x) = -14x - 3
