Answer:  The correct option is (B) 56 in².

Step-by-step explanation:  We are given to find the area of the trapezoid ABCD shown in the figure.

We know that

AREA of a trapezoid with length of the parallel sides a units, b units and height h units is given by

A=\dfrac{1}{2}(a+b)h.

For the given trapezoid ABCD, we have

a = AB = 6 in,  b = CD = 22 in   and    height, h = 4 in.

Therefore, the AREA of trapezoid ABCD is given by

A\\\\\\=\dfrac{1}{2}(a+b)h\\\\\\=\dfrac{1}{2}(6+22)\times4\\\\=2\times28\\\\=56~\textup{in}^2.

Thus, the required area of the trapezoid ABCD is 56 in².

Option (B) is CORRECT.

A water storage tank is in the shape of a hemisphere​ (half a​ sphere). If the radius is 20 ​ft, approximate the volume of the t
otez555 [7]

Answer:

The approximate volume of the tank is V=16,747\ ft^{3}

Step-by-step explanation:

we know that

The volume of a hemisphere (water storage tank) is equal to

V=\frac{4}{6}\pi r^{3}

we have

r=20\ ft

assume

\pi =3.14

substitute

V=\frac{4}{6}(3.14)(20)^{3}

V=16,747\ ft^{3}

The perimeter, p, of a square is a function of its side length, s. The perimeter of the square is 28 inches or less. What is the
CaHeK987 [17]

The domain of the function for this situation is; s<= 7.

<h3>What is the domain of the function?</h3>

It follows from the task content that the perimeter , p, of a square is a function of its side length, s. The perimeter of the square is 28 inches or less.

On this note it follows that;

P = 4s <= 28

Hence, it follows that; s<=7.

Suppose a skydiver (mass = 75kg) is falling toward the Earth. When the skydiver is 100m above the earth he is moving 60m/s. At t
sleet_krkn [62]

Answer:

Kinetic energy  = 135 kJ

Potential energy = 73.5 kJ

Explanation:

 Mass of sky diver = 75 kg

  Velocity = 60 m/s

   Height = 100 m

 Kinetic energy is given by the expression, KE = \frac{1}{2} mv^2, where m is the mass and v is the velocity.

  So Kinetic energy  = \frac{1}{2} *75*60^2=135000J=135kJ

 Potential energy is given by the expression, PE =mgh, m is the mass, g is the acceleration due to gravity value and h is the height.

 So, Potential energy = 75*9.8*100 = 73500J = 73.5 kJ
