The exact value of csc(A) is csc(A) = 7/20[√10]

From the question, we have the following parameters that can be used in our computation:

sec(A) = 7/3

Take the inverse of both sides

cos(A) = 3/7

Using the following trigonometry identity, we have

sin²(A) + cos²(A) = 1

Substitute the known values in the above equation, so, we have the following representation

sin²(A) + (3/7)² = 1

So, we have

sin²(A) = 40/49

Take the square roots

sin(A) = ±√(40/49)

The angle is in quadrant II

So, we have

sin(A) = √(40/49)

Take the inverse

csc(A) = √(49/40)

So, we have

csc(A) = 7√(1/40)

This gives

csc(A) = 7/[2√10]

Rationalize

csc(A) = 7/20[√10]

Divisibility rules or Divisibility tests have been mentioned to make the division procedure easier and quicker. If students learn the division rules in Math's or the divisibility tests for 1 to 20, they can solve the problems in a better way. For example, divisibility rules for 13 help us to know which numbers are completely divided by 13. Some numbers like 2, 3, 4, 5 have rules which can be understood easily. But rules for 7, 11, 13, are a little complex and need to be understood in-depth.

Divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10.

Example: 10, 20, 30, 1000, 5000, 60000, etc.

For any given number, to check if it is divisible by 13, we have to add four times of the last digit of the number to the remaining number and repeat the process until you get a two-digit number.  Now check if that two-digit number is divisible by 13 or not. If it is divisible, then the given number is divisible by 13.

For example: 2795 → 279 + (5 x 4)

→ 279 + (20)

→ 299

→ 29 + (9 x 4)

Step-by-step explanation:

The speed of the shadow at any time while the rock is in the air is given by v(1-s) / (H-h).

By the AAA congruency theorem, the two triangles are formed and are similar. Here, the ratio of their sides must be equal, and thus -

= H/d+s = h/s

= Hs = h(d+s)

= Hs = hd + hs

= Hs - hs = hd

= s(H-h) = hd

Differentiating both sides with respect to t -

= {s' (H- h)} + {sh'} = h'

Since we know that h' = v -

= {s' (H- h)} + {sv} = v

= s'(H-h) = v - sv

= s'(H-h) = v(1-s)

The solution of the system of equations plotted is (x,y) = (4,7).

When a system of linear equations is given, then there exist 3 cases:

Case 1: Unique single solution:

In this case, the lines of the system of equations intersect at one point. That point is the solution of both equations.

The reason we consider intersection as the solution since that the intersection point tells us that it can satisfy both of the given equations simultaneously.

Case 2: No solution:

Then there is no such point that can satisfy both equations simultaneously. Thus, there is no solution to the given system of equations.

Case 3: Infinite number of solutions:

Well, in that case, both the lines are overlapping each other. Thus, all of the points of one line lie on another line too.

And since the given lines are made up of an infinite number of points, thus we will get infinite solutions.

If f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.

What is a function?

A function is a mathematical object that assigns exactly one output to each input of a specified type. In other words, a function is a rule that takes in certain inputs (or "arguments") and produces a unique output. The inputs to a function are called the domain, while the set of possible outputs is called the range.

The given functions are f(x) = 3x and g(x)=x-2.

To find f(g(4)), we first need to evaluate g(4). The function g is defined as g(x) = x - 2, so g(4) = 4 - 2 = 2.

Next, we need to evaluate f(2), where f is defined as f(x) = 3x. So, f(2) = 3 * 2 = 6.

Therefore, f(g(4)) = f(2) = 6.

Hence, if f(x) = 3x and g(x)=x-2, then the value of f(g(4)) is 6.

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The function for this problem is defined as follows:

R(t) = 328 - 296e^(-0.004t)

At t = 0, the numeric value is found replacing the lone instance of t by zero, hence:

R(0) = 328 - 296e^(-0.004(0))

Answer: 536

Step-by-step explanation:

We know that 100% of 800 is, well, just 800.Step 2: If 100% of 800 is 800, then we can get 1% of 800 by dividing it by 100. Let's do 800 / 100. This is equal to 8.0. Now we know that 1% is 8.0.Step 3: Now that we know what 1% of 800 is, we just need to multiply it by 67 to get our solution! 8.0 times 67 = 536. That's all there is to it!

A rectangle is a polygon with four right angles and four sides. Two sides of the rectangle ABCD are AC and DB, with AC equal to 2x + 13 and DB to 4x - 1. Angle BAC is measured by 3x + 1 and angle CAD by x + 15. Angles ABD and CDB are measured as 7x - 31 and 4x + 5, respectively. Angles BDC and ADB are measured as 7x + 1 and 9x – 7 respectively. Angles AEC and AE are measured as 5x - 15 and 3x + 3 respectively.

You can find the missing sides and angles by looking at the rectangle's angles and sides. As an illustration, if AC = 2x + 13 and DB = 4x - 1, then DB = 72. Similar to this, if AC = x + 3 and DB = 3x - 19 then AC = 14. If AE = 3x + 3 and EC = 5x - 15, then AC = 6 is the result. If AE = 4x + 9 and DE = 6x - 7 then DB = 8 is the result.

The nearest thousand, there were an estimated 116,000 wild tigers 20 years ago.

The percentage decrease theory suggests that a decrease in the price of a product or service will lead to an increase in demand for that product or service.

This theory is based on the idea that consumers are more likely to buy a product or service if its price is lower. This theory can be applied to both new and existing products or services.

For example, a retailer may decide to decrease the price of a product in order to attract more customers and increase sales. Similarly, a company may choose to reduce the cost of a service in order to make it more attractive to potential customers.

This question is using the percentage decrease theory. According to this theory,

you can calculate the percentage decrease by subtracting the current value from the original value and then dividing by the original value.

Step 1: Subtract the current number of wild tigers (3200) from the original number of wild tigers (20 years ago).

Original - Current = Change

120,000 - 3200 = 116,800

Step 2: Divide the change (116,800) by the original number of wild tigers (120,000)

Change / Original = Percentage Change

116,800 / 120,000 = 97%

Step 3: Multiply the percentage change (97%) by the original number of wild tigers (120,000)

Percentage Change x Original = Estimated Original

97% x 120,000 = 116,400

Therefore, to the nearest thousand, there were an estimated 116,000 wild tigers 20 years ago.
