The angle of elevation for the given figure will be 68.198°.

<h3>What is a trigonometric function?</h3>

The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.

The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.

The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.

The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.

Given the figure is making a right-angle triangle with a base of 10m and a height of 45 - 20 = 25 m

By trigonometric function tan

Tanθ = 25/10

θ = 68.198°

Hence "The angle of elevation for the given figure will be 68.198°".

Area of circle 1 = πr² 
Area of circle 1 = π (10)²
Area of circle 1 = 100π km²

Area of circle 2 = πr²
Area of circle 2 = π (5)²
Area of circle 2 = 25π km²

Number of times the bigger circle is greater than the smaller circle 
\dfrac{100 \pi }{25 \pi } = 4

------------------------------------------------------------------------------------
Answer: The big circle is 4 times greater than the small circle.

Explain how finding 4 times 384 can help you find 4 times 5384.then find both products
forsale [732]

Answer:

Given the following: 4 times 384 can help you find 4 times 5384.

4 \times 384 = 1536                

Now, find 4 \times 5384

Using Distributive property: a\cdot (b+c) = a\cdot b + a\cdot c

We can write 4 \times 5384 as

4 \times (5000+384)

Apply distributive property we have;

4 \times 5000 + 4\times 384

Now, find both products;

we know:  4 \times 384 = 1536            

20000 + 1536 = 21,536

Part A: The exponential function is the best model for the given data. The data shows that every month the number of visitor approximately doubles from previous month. In other words the number is some base value (2, in this case) with the number of month (t) being in the exponent. This the a key characteristic of an exponential growth.  

Part B: (also explained above). Every month the number of visitors approximately doubles. Starting with 5.74 at month 8, the numbers goes up by about the same amount to 12.0 at month 9. At month 10, a similar increase occurs (doubling would be 24, and the data shows 25, so this is all "aproximate"). This trend continues throughout the table.

Part C:

Month 7 will be estimated as half of month 8 (going backward):

Month 7: 5.74/2=2.87

Estimate for month 7 = 2.87 thousand visitors.
