Answer:

Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take  as an example to see how the atoms actually bond in tetrahedron.  It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.

NemiM [27]

Answer:

The height of the statue is 21.4 feet

Step-by-step explanation:

We are given

A person is standing 50 ft from a statue

The person looks up at an angle of elevation of 16 degree when staring at the top of the statue

hen the person looks down at an angle of depression of 8 degree when staring at the base of the statue

Firstly, we will draw diagram

In triangle ABF:

FC=50

we can use trig formula

tan(16)=\frac{y}{50}

y=50tan(16)

y=14.33727ft

now, we can find x

In triangle DEF:

we can use trig formula

tan(8)=\frac{x}{50}

x=50tan(8)

x=7.0270ft

we can see that

height of statue =x+y

so, the height of statue is

=14.33727+7.0270

=21.4ft

What is the surface area of the figure shown above
gtnhenbr [62]

Answer:

  230 cm^2

Step-by-step explanation:

The area of each parallelogram face is ...

  A = bh = (8 cm)(3 cm) = 24 cm^2

The area of the two rectangular faces shown is ...

  A = (area of top face) + (area of right side face)

  A = (8 cm)(7 cm) +(5 cm)(7 cm) = 91 cm^2

The three faces we have figured the area of are half the total area, since there are three more faces exactly the same size. Then the total area of the figure is ...

  total surface area = 2(24 cm^2 +91 cm^2) = 230 cm^2

_____

Of course, the area of a rectangle is given by A=L·W, where L and W represent the length and width of the rectangle.

Suppose f(x)=x^2 what is the graph of g(x)= f(5x)
Novosadov [1.4K]

Answer:

Step-by-step explanation:

That '5' in f(5x) will compress the graph of x^2 horizontally.

If you were to graph f(x) = x^2, you'd get a parabolic graph; the parabola will open UP.

Suppose you graphed f(x) = x^2 on the interval [-4, 4].

Then the graph of g(x) = f(5x) would be graphed on the interval [-4/5, 4/5].  In other words, the graph would be on a shorter interval, one shorter by a factor of 5.
