Answer:

 c = 5 m

Explanation:

this exercise you want to divide the rectangular room into two triangular rooms

                 

the area of ​​triangles is

           A = ½ base height

           A = ½ 4 3

          A = 6 m²

the length of the curtain can be found using the Pythagorean theorem

           c² = b² + a²

           c = √ (4² + 3²)

           c = 5 m

this is the length of the curtain

Determine the kinetic energy of a 1500 kg roller coaster that is moving with a
olga2289 [7]

Answer:

<h2>918,750 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass in kg

v is the velocity in m/s

From the question

m = 1500 kg

v = 35 m/s

We have

k =  \frac{1}{2}  \times 1500 \times  {35}^{2}  \\  = 750 \times 1225 \\  = 918750

We have the final answer as

<h3>918,750 J</h3>

Hope this helps you

Answer:

The patient could be going through paralysis, which is when the motor neurons are severed which stops electrical signals from passing into the muscles.  It can be caused by severe trauma to the body or psychological stress.

The sides of a square increase in length at a rate of 3 ​m/sec. a. At what rate is the area of the square changing when the side
maks197457 [2]

The area of a square is given by:

A = s²

A is the square's area

s is the length of one of the square's sides

Let us take the derivative of both sides of the equation with respect to time t in order to determine a formula for finding the rate of change of the square's area over time:

d[A]/dt = d[s²]/dt

The chain rule says to take the derivative of s² with respect to s then multiply the result by ds/dt

dA/dt = 2s(ds/dt)

A) Given values:

s = 14m

ds/dt = 3m/s

Plug in these values and solve for dA/dt:

dA/dt = 2(14)(3)

dA/dt = 84m²/s

B) Given values:

s = 25m

ds/dt = 3m/s

Plug in these values and solve for dA/dt:

dA/dt = 2(25)(3)

dA/dt = 150m²/s
