Considering the Pythagorean theorem and the definition of perimeter, the perimeter of the triangle is 15.209 miles.

<h3>Right triangle</h3>

A right triangle is one that has an angle of 90º. The two sides that form the right angle are called legs, the opposite and longer side is called the hypotenuse.

<h3>Pythagorean theorem</h3>

The Pythagorean theorem is a mathematical premise that allows us to calculate the length of the sides of a right triangle.

The Pythagorean Theorem states the following:

<em>In any right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs</em>.

The Pythagorean theorem is only applicable to right triangles.

<h3>Definition of perimeter</h3>

The perimeter of a flat geometric figure is the length of its contour and is obtained as the result of the sum of the sides of a flat geometric figure.

<h3>Perimeter of a triangle</h3>

In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. Knowing that:

  • b=4.5 miles.
  • c=6.3 miles.

Side a can be calculated by applying the Pythagorean theorem:

c²= a² + b²

Substituting the corresponding values:

6.3²= a² + 4.5²

Solving:

6.3²- 4.5²= a²

39.69 - 20.25= a²

19.44= a²

√19.44= a

<u><em>4.4090 miles= a</em></u>

On the other hand, the perimeter of the triangle is calculated by:

perimeter= a +b +c

Substituting the corresponding values:

perimeter= 4.4090 miles + 4.5 miles + 6.3 miles

Solving:

<u><em>perimeter= 15.209 miles</em></u>

Finally, the perimeter of the triangle is 15.209 miles.

Solve the following equation: 3x^3+5x^2-4x-4=0
Rama09 [41]

Answer:

1

Step-by-step explanation:

Simplifying

3x + 2(4x + -4) = 3

Reorder the terms:

3x + 2(-4 + 4x) = 3

3x + (-4 * 2 + 4x * 2) = 3

3x + (-8 + 8x) = 3

Reorder the terms:

-8 + 3x + 8x = 3

Combine like terms: 3x + 8x = 11x

-8 + 11x = 3

Solving

-8 + 11x = 3

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 11x = 3 + 8

Combine like terms: -8 + 8 = 0

0 + 11x = 3 + 8

11x = 3 + 8

Combine like terms: 3 + 8 = 11

11x = 11

Divide each side by '11'.

x = 1

Simplifying

x = 1

A mine elevator was at a depth of -120 feet. After 15 seconds, the mine elevator was at a depth of -30 feet. What expression can
Dafna11 [192]

Answer:

The answers to the given question are:

i.  The equipment elevator is at a depth of 176 feet (-176 feet), while the miner's elevator is at a depth of 210 feet (-210 feet) below the surface.

ii. The miner's elevator is deeper than that of the equipment.

The speed of an object is the rate at which the object moves.

i.e. speed =

Thus,

Speed of the equipment elevator = 4 feet per second

Speed of the miner's elevator = 15 feet per second.

Time of descent of the equipment elevator = 30 + 14

                                 = 44 seconds

So that, the distance of the elevator at this time is;

speed =

⇒ distance = speed x time

                  = 4 x 44

                  = 176

  distance = - 176 feet

The distance of the miner's elevator after 14 seconds is:

speed =

⇒ distance = speed x time

                 = 15 x 14

                 = 210

 distance = - 210 feet

Thus, after another 14 seconds, the equipment elevator is at a depth of 176 feet (-176 feet), while the miner's elevator is at a depth of 210 feet (-210 feet) below the surface.

Therefore, the miner's elevator is deeper than that of the equipment.
