Answer:

  False

Step-by-step explanation:

The given formula is the "explicit" formula for the sequence.

The recursive formula would be ...

  a[1] = 160

  a[n] = 1/2·a[n-1] . . . . each term expressed in as a function of previous terms

The given statement is false.

Which statement is true about the end behavior of the
Wittaler [7]

Answer:

End behavior :

1. As the x-values go to positive infinity, the function's values go to negative infinity

2. As the x-values go to negative infinity, the function's values go to positive infinity.

Option D: f(x) over the interval (-4,\infty).  (answer for question in image)

Step-by-step explanation:

From the given graph it is clear that as the x-values go to positive infinity, the function's values go to negative infinity and as the x-values go to negative infinity, the function's values go to positive infinity.

It means,

f(x)\rightarrow -\infty\text{ as }x\rightarrow \infty

f(x)\rightarrow \infty\text{ as }x\rightarrow -\infty

At x=0, the value of function is -3.

Note: All options are incorrect for end behavior.

From the given graph it is clear that the function is above the x-axis before -4 and after that it is below the x-axis. So,

f(x)>0 over the interval (-\infty, -4).

f(x) over the interval (-4,\infty).

Therefore, the correct option is D.

Answer:

∠4 and ∠12

A is correct

Step-by-step explanation:

Parallel lines r and s are cut by two transversals, parallel lines t and u

r || s and t || u

We are four parallel line. Two parallel line cuts two another parallel line.

Angle 8 is form by intersection of s and t line.

Corresponding angle: When two parallel lines are crossed by transversal line,  the angles at matching corners are called corresponding angles.

For angle 8, t || u with s is transveral line.

Thus, ∠8 = ∠12  (By definition of corresponding angle)

For angle 8, s || r with t is transveral line.

Thus, ∠8 = ∠4  (By definition of corresponding angle)

Hence, ∠4 and ∠12 are corresponding angle of ∠8
