If the cos 0=3/5 use the Pythagorean identity to find sin 6
Oksanka [162]

The Pythagorean identity is

sin²Ф + cos²Ф=1

or

sin²Ф= 1- cos²Ф

Now in the problem we are given that

cos Ф=3/5

Now to find sin Ф, we can plug the value of cos Ф in the identity

So

sin²Ф= 1- cos²Ф = 1-(3/5)² = 1- 9/25 = (25-9)/25 = 16/25

Sin²Ф= 16/25

take square root on both sides

Now when we take square root on both sides we have to always remember that we will get one positive and one negative answer

So

Sin Ф = 4/5 or -4/5

Find the determinant of the matrix.
Jobisdone [24]

Answer:

-276

Step-by-step explanation:

We'll use the method of cofactors.  Use the coefficient +6 for

9   2

8   10

This gives you one third of the solution:  6 {(9)·(10) - (8)(2) },  or 444.

Next, use the coefficient 9, taking care to change the sign to -9  as follows:

     9   1

-9 |           |     =   -9(90 - 8) = -9(82) = -738  

      8  10

Finally with +2 as y our coefficient, evaluate the cofactor

9  1

9  2

ending up with  

+2(18-9) = +2(9) = 18

Finally add these three results together:

+444 - 738 + 18  =  -276

This, the determinant, D, is -276 (the fourth answer choice)

Zigmanuir [339]

Answer:

<em>The answer is Domain = {3,2,5,6,0} and Range =  {2,4,-3,-7,0}</em>

Step-by-step explanation:

    We have given some points such as (3,2)(2, 4) (5,-3) (6.-7) (0,0)

    As we know as the definition of domain is

    Domain means the input value we are giving to the function is known to

    be the domain of the function

    such that y = f(x) .................................................................. (1)

    where x is the domain

    Range means the output value of the corresponding input such as in

    equation (1) we get y value as value of range

    Domain of the given problem is {3,2,5,6,0}

    Range of the given problem is {2,4,-3,-7,0}

    <em>The answer is Domain = {3,2,5,6,0} and Range =  {2,4,-3,-7,0}</em>
