tan13pi/4 A. Use the fact that there are 2pi radians in each circle to find another angle, smaller than 2 pi, that is equivalent

to 13pi/4. B. Find the tangent of the angle you found in part A. This is also 13pi/4.

Answer:

1

Step-by-step explanation:

Tan 13π/4 = tan(3π + 1/4π)

According to the trigonometry identity;

tan(A+B) = tanA + tanB/1-tanAtanB

If A = 3π and B = π/4

tan(3π + 1/4π) = tan 3π + tanπ/4/1-tan3πtanπ/4

If πrad = 180°

tan(3π + 1/4π) = tan 540° + tan45°/1-tan540°tan45°

tan(3π + 1/4π) = 0+1/1-0(1)

tan(3π + 1/4π) = 1/1-0

tan(3π + 1/4π) = 1/1

tan(3π + 1/4π) = 1

tan 13π/4 = 1

Hello : 
13π/4  = (16-3)π/4
            = 16π/4 -3π/4
  13π/4  = -3π/4 +4π   
 tan( 13π/4) = tan ( -3π/4)= -  tan ( 3π/4)  =- tan( π - π/4) = - tan(- π/4)
tan( 13π/4) = -(-tan(π/4)) =tan(π/4)=1

Darya [45]

Write a C program to compute Matrix Multiplication of two matrices. Use one dimensional array to store each matrix, where each row is stored after another. Hence, the size of the array will be a product of number of rows times number of columns of that matrix. Get number of row and column from user and use variable length array to initialize the size of the two matrices as well as the resultant matrix. Check whether the two matrices can be multiplied or not. Write a getMatrix() function to generate the array elements randomly. Write a printMatrix() function to print the 1D array elements in 2D Matrix format. Also, write another function product(), which multiplies the two matrices and stores in the resultant matrix. With SEED 5, the following output is generated.


Sample Output


Enter the rows and columns of Matrix A with space in between: 3 5


Enter the rows and columns of Matrix B with space in between: 5 4


Matrix A:


   8     6     4     1     6


   2     9     7     7     5


   1     3     1     1     2

   9     9     8     1


   4     4     3     5




   2     6     2     1


   4     5     2     4


Product AxB:


168   146   106    91


161   186   125    81


50    52    37    22


In conclusion, the answer is D; No, because they are not similar triangles.

#10-1 : What is the probability of randomly choosing a diamond card from a regular deck of 52 cards? What is the probability of
Alchen [17]

\huge{\boxed{\frac{1}{4}}}\ \ \huge{\boxed{\frac{1}{4}}}

There are 13 of each suit in a deck of 52 cards.

This means the probability of drawing a diamond card is \frac{13}{52}. You can divide the numerator and denominator each by 13 to simplify. \frac{13}{52} \div \frac{13}{13} = \boxed{\frac{1}{4}}

Since there are the same number of clubs as there are diamonds, the probabilities are the same.

Question 4 of 18
makkiz [27]

Answer b. The probability that at least 41 of them like to swim is 33%.

Solution:

The probability of an event is always 1 or 100%

The probability of at most 40 of them like to swim is 67% = 0.67

The probability of at most 40 not swimming = 1 - 0.67 = 0.33

Hence the probability of at least 41 people swimming is 33%.

<h3>What is Probability?</h3>
  • The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
  • An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
  • The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the odds of both the possibilities, "heads" and "tails," are equally likely to occur. As a result, the probability of either occurrence is half.

2 feet to 2 yards ratio
vredina [299]

Answer:

\frac{1}{3}

Step-by-step explanation:

Three feet make a yard, so 2 yards is 6 feet

\frac{2}{6}  If we divide the top (numerator) and the bottom (denominator) by 2 we get

\frac{2}{6} ÷ \frac{2}{2} = \frac{1}{3}

△ABC = △DBC, AB= 10, AC=7 DC= ?
Furkat [3]

Answer:DC=7

Step-by-step explanation:

As it is written △ABC = △DBC.   So the corresonding legs (the legs which are equal ) are as follows:

AC=DC       AB=DB      BC= BC

So DC=7  the same like AC
