AnnZ [28]3 years ago
6 0

Answer:

Normally, Acceleration due to gravity is

9.8m/s^2\\

or

10m/s^2

Step-by-step explanation:

From the web

These two laws lead to the most useful form of the formula for calculating acceleration due to gravity: g = G*M/R^2, where g is the acceleration due to gravity, G is the universal gravitational constant, M is mass, and R is distance

a person is standing on top of a smaller building looking across the street at a taller building, which is 260 feet away horizon
Anuta_ua [19.1K]

The height of the smaller building is <u>94.63 feet</u>, computed using the trigonometric ratios.

In the question, we take AB to be the taller building, where A is its top and B is its base, CD to be the shorter building, where C is its top and D is its base, and CE to be the perpendicular from C to AB.

Given that the horizontal distance between the two buildings is 260 feet, we can say that BC = CE = 260 feet.

The angle of elevation from the top of the shorter building to the top of the taller building is 30°, that is, ∠ECA = 30°.

The angle of depression from the top of the shorter building to the base of the taller building is 20°, that is, ∠ECB = 20°.

When ∠ECB = 20°, then ∠CBD = 20°, as they are alternate angles.

We are asked to find the height of the shorter building, that is, we are asked to find CD.

In ΔCBD,

tan ∠CBD = CD/BD {perpendicular/base},

or, tan 20° = CD/260,

or, CD = 260*tan 20° = 260*0.36397023426 {∵ tan 20° = 0.36397023426},

or, CD = 94.6322609092.

Therefore, the height of the smaller building is <u>94.63 feet</u>, computed using the trigonometric ratios.

7.003 x 10 to the power of 4
pishuonlain [190]
In scientific notation, just move the decimal point over however many numbers are in the power. 

In 7.003 • 10^4, move the decimal point over 4 places to the right, (or left if it's negative) making it 70,030

What is the circumference of a circle with a radius of 80 inches? (Use Pi = 3.14)
Bingel [31]

Answer:

The  circumference  of given circle = 502.4 inches

Step-by-step explanation:

Formula:

Circumference of circle = 2πr

Where r - Radius of circle

and π is a constant value

<u>To find the Circumference of circle</u>

Here

radius r = 80 inches and

π = 3.14

Circumference = 2πr = 2 * 3.14 * 80 = 502.4 inches

Therefore Circumference  of given circle = 502.4 inches
