–81, 108, –144, 192, ...Which formula can be used to describe the sequence?
A.f(x) = –81(4/3)^x-1
B. f(x) = –81(-3/4)^x-1
C. f(x) = –81(-4/3)^x-1
D. f(x) = –81(3/4)^x-1

Answers

r = 108/-81 = -144/108 =192/-144 = -4/3
This is a geometric sequence with a common ratio (r) = -4/3
The nth term of a geometric sequence is given by tn = ar^(n-1) where a is the 1st term.
Therefore, the formular for the sequence is f(x) = -81(-4/3)^(x-1)
Answer: C [f(x) = -81(-4/3)^(x-1)]

Answer: C. f(x) = -81(-4/3)^(x-1)

if Cory is at the elephant and he walks 8 units up and 4 units right, where would he land? What are his new coordinates?

Answers

Answer: The new coordinates are (-2, 7)

===========================================================

Reasoning:

The elephant is at location (-6,-1)

Move 8 units up and we move to (-6,7). Add 8 to the y coordinate while keeping the x coordinate the same.

Then we move 4 units to the right to arrive at (-2, 7). I added 4 to the x coordinate and kept the y coordinate the same.

There are no animals at this location, but Cory is between the giraffe and the deer. In other words, if you draw a line segment from the giraffe to the deer, then Cory's new location is on this line segment. He is closest to the giraffe.

The information given represents lengths of sides of a right triangle with c the hypotenuse. Find the correct missing length to the nearest hundredth. A calculator may be helpful.a = 20, b = 28, c = ?

A.34.41

B.35.45

C.35.88

D.34.72

Answers

The correct answer for the question that is being presented above is this one: "A.34.41." The information given represents lengths of sides of a right triangle with c the hypotenuse.

h^2 = a^2 + b^2
c^2 = 20^2 + 28^2
c^2 = 400 + 784
c^2 = 1184
c = 34.41

What is the measure of an exterior angle of a regular quadrilateral

Answers

-- Any "regular" polygon has all sides equal AND all angles equal.

-- The sum of the angles inside a 4-sided figure is 360° .

-- So it it's a regular figure, then each angle is 360°/4 = 90° .

-- The total angle around each vertex is 360° .
If 90° of them are inside, then the exterior angle is the remaining 270° .

Answer:

90 degrees

Consider f(x)=2|x|What is the rate of change over the interval 0≤x≤4?

How is the rate of change over this interval related to the form of the function?

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

As we know that the average rate of change of f(x) in the closed

interval [a, b] is

$(f\left(b\right)-f\left(a\right))/(b-a)$

Given the interval [a, b] = [0, 4]

$f(x)=2|x|$

$f(b)=f(2)=2\cdot \:4$ ∵ $\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0$

$= 8$

$f(x)=2|x|$

$f(a)=f(0)=2\cdot \:0$ ∵ $\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0$

$= 0$

so the average rate of change :

$(f\left(b\right)-f\left(a\right))/(b-a)=(8-0)/(4-0)$

$=(8)/(4)$

$= 2$

We know that a rate of change basically indicates how an output quantity changes relative to the change in the input quantity. Here, it is clear the value of y increase with the increase of input.
