Answer:
At a distance of 525 km from the station both trains meet.
Step-by-step explanation:
Speed of the first train = 75
Speed of the second train = 105
Distance traveled by first train in two hours = 75 × 2 = 150 km
When the first train traveled a distance of 150 km than second train starts from the station.
Let suppose the two trains meet after T hours.
Value of T is given by
Put the value of D & & we get
T = 5 hours
Thus the two trains meet after 5 hours &
⇒ Distance from the station is = Speed of second train × 5
⇒ Distance from the station is = 105 × 5
⇒ Distance from the station is = 525 km
Therefore at a distance of 525 km from the station both trains meet.

Step-by-step explanation:
Take the beginning number and add or subtract each transaction to get a new balance. For example,
349.45
- 23.42 = 326.03
- 14.95 = 311.08
+ 276.50 = 587.58
- 219.93 = 367.65
- 76.84 = 290.81
Answer:
Its 58
Step-by-step explanation:
Because the bigger triangle is a dilation of the smaller one. In other words only the sides get bigger, the angles stay the same.
You simply need to mulotiply those two numbers
Then u get 126!

Answer:
You need to have some idea where you want to start if you're going to derive equations for these. You can start with a definition based on focus and directrix, or you can start with a definition based on the geometry of planes and cones. (The second focus is replaced by a directrix in the parabola.) In general, these "conics" represent the intersection between a plane and a cone. Perpendicular to the axis of symmetry, you have a circle. At an angle to the axis of symmetry, but less than parallel to the side of the cone, you have an ellipse. Parallel to the side of the cone, you have a parabola. At an angle between the side of the cone and the axis of the cone, you have a hyperbola. (See source link.)
You can also start with the general form of the quadratic equation.
.. ±((x-h)/a)^2 ± ((y-k)/b)^2 = 1
By selecting signs and values of "a" and "b", you can get any of the equations. (For the parabola, you probably need to take the limit as both k and b approach infinity.)
