Answer: see proof below
Step-by-step explanation:
Use the Sum & Difference Identity: tan (A - B) = (tanA - tanB)/(1 + tanA tanB)
Use the Half-Angle Identity: tan (A/2) = (1 - cosA)/(sinA)
Use the Unit Circle to evaluate tan (π/4) = 1
Use Pythagorean Identity: cos²A + sin²A = 1
Proof LHS → RHS

In 2003, the population of an African country was about 19.5 million people, which is 2 million more than 5 times the population in 1950. Enter and solve an equation to find the approximate population p (in millions) in 1950.
Answer:
[tex]P = 3.5\ million[/tex]
Step-by-step explanation:
Given
Represent 1950 Population with P and 2003 Population with Q
[tex]Q = 19.5\ million[/tex]
Required
Determine the value of P
From the question; we have that
[tex]Q = 2\ million + 5 * P[/tex]
Substitute 19.5 million for Q
[tex]19.5\ million = 2\ million + 5 * P[/tex]
Subtract 2 million from both sides
[tex]19.5\ million - 2\ million= 2\ million - 2\ million + 5 * P[/tex]
[tex]19.5\ million - 2\ million= 5 * P[/tex]
[tex]17.5\ million = 5 * P[/tex]
Divide both sides by 5
[tex]\frac{17.5\ million}{5} = \frac{5 * P}{5}[/tex]
[tex]\frac{17.5\ million}{5} = P[/tex]
[tex]3.5\ million = P[/tex]
[tex]P = 3.5\ million[/tex]
Hence, the 1950 population is 3.5 million
If n denotes a number to the left of 0 on the number line such that the square of n is less than \small \frac{1}{100}, then the reciprocal of n must be
Answer:
The reciprocal of n must be less than 10.
Step-by-step explanation:
It can be inferred from the question given that n is not a negative number.
But,
[tex](n)^{2}[/tex] < [tex]\frac{1}{100}[/tex]
Find the square root of both sides,
n < [tex]\sqrt{\frac{1}{100} }[/tex]
⇒ n < [tex]\frac{1}{10}[/tex]
n < 0.1
The reciprocal of n can be estimated as;
[tex](n)^{-1}[/tex] < [tex](\frac{1}{10}) ^{-1}[/tex]
[tex]\frac{1}{n}[/tex] < 10
The reciprocal of n is less than 10.

Answer: 4 or [tex]\sqrt{4 * 4}[/tex]
To find the square root of a number, remember that there will be two factors that are the same that will give you the product.
Lets start from 1:
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16
As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.
4 and 4 are the same numbers.
Therefore, [tex]\sqrt{16}[/tex] = 4
It can also be written as [tex]\sqrt{4 * 4}[/tex]
Answer:
the answer is 4

At a local discount theatre, tickets to the film The
Early Bird Gets the Sleepiest cost only $2.50 for
adults and $1 for children. If 19 people attended
the last showing and the theatre sold $40 worth of
tickets:
a.) How many adults attended the showing?
b.) How many children attended the showing?
Answer:
14 adults and 5 children
Step-by-step explanation:
Set up a system of equations, where a is the number of adults and c is the number of children:
2.5a + c = 40
a + c = 19
Multiply the bottom equation by -1 to solve by elimination:
2.5a + c = 40
-a - c = -19
1.5a = 21
a = 14
Now, plug in 14 as a to find the number of children:
a + c = 19
14 + c = 19
c = 5
So, 14 adults and 5 children attended

Two lines extend from point S to create a right angle. The vertical line extends from point S through point R. The horizontal line extends right from point S through point T. A third line extends right and up from point S through point U. Which is the endpoint of a ray? point R point S point T point U
Answer:
Option R
Step-by-step explanation:
The point S is the end point of ray.
What is line?
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.
According to the given information,
A ray's endpoint is a single point that denotes the conclusion of a line segment. In this instance, only one of the three lines that extend from point S contains a ray's terminus.
We must comprehend a ray's qualities in order to establish which location is the endpoint of a ray.
A ray originates at a single place and travels in one direction indefinitely. The beginning of the line segment is the endpoint of a ray.
We can see from the provided lines that the vertical line runs from point S via point R. Since it doesn't go on forever in one direction, this is not a ray example.
Similar to the vertical line,
The horizontal line also extends from point S through point T,
But it does not go on forever.
The third line is a ray because it is infinitely long in one direction and extends right and up from point S via point U.
Therefore, point S, the beginning of the line, is the endpoint of this ray.

**50 Points Possible** I NEED URGENT HELP
please provide a graph
Answer:
See below.
Step-by-step explanation:
1)
For Ben's social media post, we are told that it was initially shared to only 2 people. However, each of those shares it with 3 people. In other words, Ben's post triples every day. This means that the rate of growth is 3. Thus, Ben's post as an exponential function is:
[tex]f(x)=2(3)^x[/tex]
The 2 represents the initial amount at day 0, and the 3 represents the rate at which the post grows each day.
2)
Similarly, Carter's post was originally sent to 10 people. However, each of the 10 shares it with two others. Therefore, it doubles each day. Thus, the rate is 2. So, Carter's exponential function is:
[tex]f(x)=10(2)^x[/tex]
The 10 represents the initial amount while the 2 represents the rate.
3)
I've use Desmos to graph the functions. Refer to the picture attached. Red is Amber, blue is Ben, and green is Carter.
4)
To find out the number of shares each student's post will receive on day 3 and day 10, simply plug the numbers into the functions. Therefore:
For Amber:
Day 3:
[tex]f(3)=3(4)^3=192[/tex]
Day 10:
[tex]f(10)=3(4)^{10}=3,145,728[/tex]
For Ben:
Day 3:
[tex]f(3)=2(3)^3=54[/tex]
Day 10:
[tex]f(10)=2(3)^{10}=118,098[/tex]
And for Carter:
Day 3:
[tex]f(3)=10(2)^3=80[/tex]
Day 10:
[tex]f(10)=10(2)^{10}=10,240[/tex]
5)
Amber's new graph of:
[tex]f(x)=3(4)^x+45[/tex]
will be a shifted version of her original graph. The new graph will be shifted upwards by 45 units. However, since the 45 is not affected by the x in any way, the change will be minuscule. For instance, her number of shares on day 10 of the old graph is 3,145,728. Even with the additional 45, it will just be: 3,145,773. With enough days, the additional number becomes trivial.
6)
On the 10th day, Amber's post was shared almost 3 million times, while Ben's was shared "only" 118,098 times and Carter's with 10,240. Undoubtedly, Amber's post was the fastest.
7)
If you want to most shares as possible, choose Amber with fewer friends initially but more shares. This is because the exponential potential of a number even just a bit higher is insane. For instance, 3^10 (Ben's rate at 10th day) is only 59,049 while Amber's rate will be 4^10 which is 1,048,576. Amber's number is almost 18 times higher than Ben's. Even if Ben's initial number was say 1,000 or even 1,000,000, Amber would catch up rather quickly. Therefore, the rate is the quintessential part of an exponential growth function.

Here is the slope:

First of all, find the length of AB and CD using the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
A(-6, 2) => (x1, y1)
B(3, 2) => (x2, y2)
[tex] AB = \sqrt{(3 -(-6))^2 + (2 - 2)^2} [/tex]
[tex] AB = \sqrt{(9)^2 + (0)^2} = \sqrt{81} = 9 [/tex]
[tex] CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
C(-2, 6) => (x1, y1)
D(-2, 2) => (x2, y2)
[tex] CD = \sqrt{(-2 -(-2))^2 + (2 - 6)^2} [/tex]
[tex] CD = \sqrt{(0)^2 + (-4)^2} = \sqrt{16} = 4 [/tex]
AB = 9
CD = 4
Area of rectangle = ½*AB*CD = ½*9*4 = 9*2 = 18 square units.

A fountain was marked up 170% from an original cost of $1000. Last Friday ,Bernie bought the fountain and paid and additional 13% in sales tax.what was his total cost?
Answer:
$ 3051
Step-by-step explanation:
Original cost = $ 1000
Marked up Price = Original cost + 170% of 1000
= 1000 + 1.7 * 1000
= 1000 + 1700
= $ 2700
Sales tax = 13% of 2700
= 0.13 * 2700
= 351
Total cost paid by Bernie = 2700 + 351 = $ 3051

The length of a side of a square field is 48m.Find the cost of ploughing the field at the rate of rs 25/m and cost of fencing the field at the rate of rs 18/m
Answer: rs 4800, rs 3456
Step-by-step explanation:j
given data:
length of a sid = 48m
cost of ploughing the field = rs 25/m
cost of fencing the field = rs 18/m
solution:
we know a square has four equal sides. so total length of the field is
= m ( 48 + 48 +48 + 48 )
= 192m
cost of ploughing the field
= 192m * rs 25
= rs 4800
cos of fencing the field
= 192m * rs 18
= rs 3456
