For this we will use kinematic equations.

We need the time of flight to compute the range.

With the given information, the most useful formula is:

Δy=v0yt−g2t2

Because our equation is taking only vertical motion into account,

v0y=30sin(45)

Because we are looking for the range of the object,

Δy=0

This leaves us with only one unknown:  t

0=30sin(45)t−g2t2

g2t2=30sin(45)t

g2t=30sin(45)

t=60gsin(45)

For horizontal distance, the formula we need is:

Δx=v0xt

Because we are taking into account the horizontal range,

v0x=30cos(45)

In substituting our derived values into the equation we can see that:

Δx=30cos(45)∗60gsin(45)

Range=30cos(45)∗60gsin(45)

What was the legacy Louis XIV left for his successor, Louis XV?
lidiya [134]

In the king's final hours, he received his five-year-old great-grandson, the successor future Louis XV, to share his legacy. He advised his grandson to try to avoid going to war as much as possible, and to focus on relieving the burden on the people. He said that this was the ruin of the people.

<h3>What does legacy mean?</h3>

A legacy is someone who has three mortal grandparents and one godly grandparent, or who is a further descendant of a particular deity. There is no distinction between a legacy of Ares/Mars and a legacy of Zeus/Jupiter because a legacy only counts the god it is descended from as an ancestor, not that deity's parents or grandparents. But through different ancestral combinations, it is possible to carry the genetic legacy of two or more gods.

As with Octavian's gift of prophecy or Periclymenus' descendants gaining the ability to change their shape, it is demonstrated that legacies can occasionally possess the skills of their divine ancestor. Some legacies do possess the skills of their divine ancestor, but this is only true of some of them.

The five members of the traynor family each buy train tickets. During the train ride, each family member buys a boxed lunch for
OLga [1]

Answer:

Each ticket is $43.20

Explanation:

If there are five family members, and the meals are $.6.50 each, we will multiply $6.50 by 5.

$6.50 × 5= $32.5

Now we subtract the meals from the total of $248.50.

$248.50 - $32.5= $216

All five tickets cost $216, now we divide this by 5 since five tickets were bought.

\frac{216}{5}= $43. 2

Each ticket was $43.20

Let's double-check:

$32.5 + $43.20(5)= $32.5 + $216= $248.50
