Answer:

x = 83 degree

Step-by-step explanation:

x + 43 = 126 (sum of two interior opposite angle is equal to the exterior angle formed)

x = 126 - 43

x = 83 degree

Answer:

83 degrees

Step-by-step explanation:

To find this you first find the angle opposite to 126. To do this you subtract 126 from 180 as 180 degrees is a straight line, and we are looking for that missing angle.

This equals 54 degrees.

Now, 54 + 43 equals 97.

Because all interior angles of a triangle always equal 180, you can find that last angle by subtracting 97 from 180. This leaves you with 83 degrees.

Nonamiya [84]

Answer:

False

Step-by-step explanation:

Assuming a and b are 2 different terms,

Sqrt a + Sqrt b is not equal to Sqrt (a * b).

The only way to obtain Sqrt (a * b) is by doing the following:

Sqrt (a * b) = Sqrt (a) * Sqrt (b)

Answer:

1. $a_{n}=\frac{1}{3} a_{n-1}$ where $a_{1} =27$

2. $2^{x+1}$

3. The domain is {-12,-8,0,1}. The range is {0,12,8}.

Step-by-step explanation:

1. The recursive formula is defined as an implicit way of writing the rule of a function or pattern. It is implicit because it uses previous terms to find the next term in the pattern. We multiply, add, subtract or divide a previous term by a constant value or expression to find the next. In this case, 27 becomes 9 through division by 3 or multiplication by 1/3. The pattern continues 9(1/3)=3 and so forth.

2. The function f(x) is an exponential and has a general form of $y=ab^x$ . We know f(x) is $2^x$ . The points of g(x) all changed from f(x) by shifting over to the left. This transformation occurred by $2^{x+1}$ .
