Consider the sequence -2, 6, -18, 54,

hram777 [196]

Answer: The sequence is geometric

Step-by-step explanation:

In an arithmetic sequence, the consecutive terms differ by a common difference and this difference is linear.

Common difference = given term - the term before it

In geometric progression, the consecutive terms differ by a common ratio this difference is exponential.

Common ratio = given term/the term before it

Looking at the given sequence,

1) d = 6 - - 2 is not equal to - 18 - 6

Therefore, it is not an arithmetic sequence

2) r = 6/- 2 = - 18/6 = - 3

Therefore, it is a geometric sequence.

nika2105 [10]

Answer:

The value of the car in very nice condition is $28,500.

Step-by-step explanation:

Consider the provided information.

In 1955 an antique car that originally cost 3,943 is valued at 64,125 if in excellent condition, winch is 2 1/4 times as much as a car in very nice condition.

The mixed fraction can be written as:

$2 \frac{1}{4}=\frac{9}{4}$

Let x is the value of car in very nice condition.

$64,125 =\frac{9}{4}x$

$x=\frac{64,125\times 4}{9}$

$x=28,500$

Hence, the value of the car in very nice condition is $28,500.

Question 5 of 30<br> What is the period of the graph of y<br> 5cos(4x – 1) + 3?

Anastaziya [24]

Answer:

Period is $\frac{\pi}{2}$

Step-by-step explanation:

For the function $y=acos(bx-c)+d$ , the period is $\frac{2\pi}{|b|}$ .

Therefore, the period of the function is $\frac{2\pi}{|b|}=\frac{2\pi}{|4|}=\frac{2\pi}{4}=\frac{\pi}{2}$ .

What this means is that the function's wave cycle will repeat every $\frac{\pi}{2}$ units.
