Step-by-step explanation:
This triangle is a 45-45-90 triangle.
By using the image I posted, we can find x easily.
So, we have as one of the sides.
They hypotenuse, which is x is just
Simplify and we get x =

Answer:
The correct option is (D).
Step-by-step explanation:
The two expressions are:
On simplifying both the expressions we get:
Compute the value of both expressions for <em>x</em> = 2 as follows:
The value of both expressions are same for <em>x</em> = 2.
Thus, the correct option is:
"They are equivalent because when x = 2, the two expressions have the same value."
Answer:
The speed of the bus is 74.242 kilometers per hour.
Step-by-step explanation:
Let suppose that bus runs at constant speed and that speed is measured in kilometers per hour. Then, the speed of the bus (), in kiometers per hour, is determined by following kinematic expression:
(1)
Where:
- Travelled distance, in kilometers.
- Time, in hours.
If we know that and
, then the speed of the bus is:
The speed of the bus is 74.242 kilometers per hour.
