Train A and Train B start off at the same point and are traveling in the same direction. It takes Train A 30 minutes to get to S
kaheart [24]

Answer:

No difference

Step-by-step explanation:

The given parameters are;

The point Train A starts off = The point Train B starts off

The direction of travel of Train A = The direction of travel of Train B

The time it takes Train A to get to Station X, t₁ = 30 minutes = 0.5 hour

The speed of Train A, v₁ = 100 miles per hour

The time it takes Train B to get to Station Y, t₂ = 100 minutes = (5/3) hours

The speed of Train B, v₂ = 30 miles per hour

The distance from the starting point to Station X, d₁, is given as follows;

v₁ = d₁/t₁

∴ d₁ = v₁ × t₁

By substituting the known values, we have;

d₁ = 100 mph × 0.5 h = 50 miles

The distance from the starting point to Station Y, d₂, is given as follows;

v₂ = d₂/t₂

∴ d₂ = v₂ × t₂

By substituting the known values, we have;

d₂ = 30 mph × (5/3) h = 50 miles

Therefore;

The difference in the distances to Station X and Station Y = d₁ - d₂

d₁ - d₂ = 50 miles - 50 miles = 0

∴ The difference in the distances to Station X and Station Y = 0 (No difference).

Find the area of the region that lies under the parabola y=5x - x^2, where 1≤x≤4. I would definitely like to see some work :)
Elena L [17]

Answer:

  16.5 square units

Step-by-step explanation:

You are expected to integrate the function between x=1 and x=4:

  \displaystyle\text{area}=\int_1^4{(5x-x^2)}\,dx=\left.\left(\dfrac{5}{2}x^2-\dfrac{1}{3}x^3\right)\right|_{x=1}^{x=4}\\\\=\dfrac{5(4^2-1^2)}{2}-\dfrac{4^3-1^3}{3}=37.5-21=\boxed{16.5}

__

<em>Additional comment</em>

If you're aware that the area inside a (symmetrical) parabola is 2/3 of the area of the enclosing rectangle, you can compute the desired area as follows.

The parabolic curve is 4-1 = 3 units wide between x=1 and x=4. It extends upward 2.25 units from y=4 to y=6.25, so the enclosing rectangle is 3×2.25 = 6.75 square units. 2/3 of that area is (2/3)(6.75) = 4.5 square units.

This region sits on top of a rectangle 3 units wide and 4 units high, so the total area under the parabolic curve is ...

  area = 4.5 +3×4 = 16.5 . . . square units

The mean of a set of data is 45 years. Find the missing numbers in the data set {40,45,48,?,54,?,45}. Explain the method or stra
Vera_Pavlovna [14]

Answer:

42 and 41

Step-by-step explanation:

So how I did it tbh I went everywere with this but I went backwards because the how you find the mean of something is adding all the values and then dividing them by the number of values(40+41+42+45+45+48+54=315, 315divided by 7=45) but anyway 45x7(because multiplication is the opposite of division)that equals 315-232 which is the answer to 40+45+48+54+45 which were the numbers that were given
