Mathematics

deff fn [24]2 years ago
8 0

Step-by-step explanation:

For question no. 3

Since we are aware that measure of the sum of all the three interior angles of a triangle is 180°.

135 \degree + 25\degree +( 2x + 2)\degree  =  180 \degree \\  \\  \therefore \:  2x\degree  = 180 \degree  - 152 \degree  \\  \\ \therefore \:  2x\degree  = 28 \degree    \\  \\ \therefore \:  x\degree  =  \frac{28 \degree}{2}     \\  \\  \therefore \: x = 14

Which recursive sequence would produce the sequence 8,-35,137,…?
vagabundo [1.1K]

The recursive sequence that would produce the sequence 8,-35,137,… is T(n + 1) = -3 - 4T(n) where T(1) = 8

<h3>How to determine the recursive sequence that would produce the sequence?</h3>

The sequence is given as:

8,-35,137,…

From the above sequence, we can see that:

The next term is the product of the current term and -4 added to -3

i.e.

Next term = -3 + Current term * -4

So, we have:

T(n + 1) = -3 + T(n) * -4

Rewrite as:

T(n + 1) = -3 - 4T(n)

Hence, the recursive sequence that would produce the sequence 8,-35,137,… is T(n + 1) = -3 - 4T(n) where T(1) = 8

2/ 9 = ? / (14 + ?)      cross mutiply

28 + 2? = 9?

28 = 7?

X - 5y = 10; (0, -2) Group of answer choices no yes
mr Goodwill [35]
  • Yes, this linear equation is correct on point (0,-2).

Given that:

  • The linear equation

         x - 5y = 10;

  • The point

        (0, -2)

To find

  • We have to prove LHS = RHS

So, according to the question

We have,

The linear equation,

         x - 5y = 10; and point is (0,-2)

From equation,

         x - 5y = 10

Take the left part of given linear equation,

         LHS = x - 5y

Now, putting the values, x = 0 and y = -2.

Then, we will be get.

                = x - 5y

                = (0) - 5 ×(-2)

                = - 5 × -2

                = 10.

So, we can say that

          LHS = RHS.

Where,

           LHS = Left Hand Side.

           RHS =  Right Hand Side.      

We can solve that linear equation in other way,

When we put x = 0, we get y = -2.

So, if we put x = 1, we get y = -9/5.

Similarly, if x = 2, then y = -8/5.

Now, we can say that points (0,-2), (1,-9/5) and (2,-8/5) are lie in the linear equation x - 5y = 10.
