Tan 45°. tan² 30° tan 60° slove it​

Mathematics
1 answer:
makvit [3.9K]1 year ago
4 0

Answer:

\frac{\sqrt{3} }{3} or \frac{1}{\sqrt{3} }

Step-by-step explanation:

We can break the problem into three parts,

tan45 = sin(45)/cos(45)=\frac{\frac{\sqrt{2}}{2} }{\frac{\sqrt{2}}{2} } =1

tan^{2}30 =(tan30))^{2}=(sin30/cos30)^2=((1/2)/(\sqrt{3}/2))^2 =(1/\sqrt{3})^2

tan60=sin60/cos60=\frac{\sqrt{3}/2 }{1/2} =\sqrt{3}

Then, tan45*tan^230*tan60=1*(1/sqrt(3))^2*sqrt(3)=1/sqrt(3)=sqrt(3)/3

Therefore, the solution is sqrt(3)/3

How many ways can 6 people sit on a bench if 3 of them have to sit side by side
pickupchik [31]

Answer:

144 ways

Step-by-step explanation:

Let's think of the 3 persons sitting together as "one". So essentially we have 3 + "1" = "4" persons to arrange.

THey can be arranged in 4! ways, which is:

4! = 4 * 3 * 2 * 1 = 24 ways

Now, the 3 persons themselves can be arranged in 3! ways, which is:

3! = 3 * 2 * 1 = 6 ways

Total ways = 4! * 3! = 24 * 6 = 144 ways

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER. What is the volume
GarryVolchara [31]

Answer:

114.3cm^3

Step-by-step explanation:

Square Pyramid Formulas derived in terms of side length a and height h: Volume of a square pyramid

V = (1/3)(Base area of a square)(Height of the square pyramid).

V = (1/3)area^{2}hight

Area of the square

A = 7 x 7

A = 49

V = (1/3)49 x 7

V = (1/3)343

V = 114.(a repeating term)3

since we rounded

V = 114.3cm^3

The revenue for a company producing widgets is given by y = -20x2 - 50x + 200, where x is the price in dollars for each widget.
lisov135 [29]

Answer:

The  price is   x =  $2.779

Step-by-step explanation:

From the question we are told that

  The  revenue is  y = - 20x^2  - 50 x + 200

   The cost of production is  y = 30 x - 10

Generally at break even point the cost of production is equal to the  revenue

So

      -20x^2 -50x + 200 =  30x-10

=>   20x^2 +20 -210 = 0

Using the quadratic formula to solve this equation we have that

       x =  $2.779
