Answer 1
Answer:

Answer:

The correct option is C.

Step-by-step explanation:

A general exponential function is defined as

y=a(1+r)^x

Where, a is initial value and r is growth rate.

The sales of company A is

y=340(1.03)^x

It can be written as

y=340(1+0.03)^x

Therefore the initial sales of company A is 340 and percent of increase is 3%.

The sales of company B is

y=275(0.89)^x

It can be written as

y=275(1-0.11)^x

Therefore the initial sales of company B is 275 and percent of increase is -0.11%. It means sales decrease by 11%.

The sales of company C is

y=180(1.23)^x

It can be written as

y=180(1+0.23)^x

Therefore the initial sales of company C is 180 and percent of increase is 23%.

The sales of company D is

y=260(1.90)^x

It can be written as

y=260(1+0.90)^x

Therefore the initial sales of company D is 260 and percent of increase is 90%.

We have to rank the company sales by smallest to largest percent of increase.

-11\%<3\%<23\%<90\%

B<A<C<D

Therefore the correct option is C.

Which explains why the graphs of geometric sequences are a series of unconnected points rather than a smooth curve?The range contains only natural numbers.

The domain contains only natural numbers
.
Exponential bases must be whole numbers.

Initial values must be whole numbers.

Answers

The correct answer is:


The domain contains only natural numbers .


Explanation:


The domain of a geometric sequence is the set of term numbers. This is the position of each term in the sequence: first, second, third, etc.


Since the domain is the set of positions, there are no decimal or fraction numbers in the domain. There would be no "2 and a half" term; it goes from the second to third.


This means that the values between the terms of the sequence have no value, and the graph will not be connected.

Answer: B.

(The domain contains only natural numbers.)

Step-by-step explanation:

Solve for x: 25x2 − 36 = 0

Answers

25x^2-36 = 0 \n\n(5x)^2-6^2=0\n \n(5x-6)(5x+6)=0\n \n5x-6=0 \ \ or \ \ 5x+6=0\n \n5x=6 \ \ or \ \ x=-6\n \nx=(6)/(5) \ \ or \ \ x=-(6)/(5) \n \n \n a^2-b^2 =(a-b)(a+b)
25x^2-36=0

25x^2=36

x^2=(36)/(25)

x=\sqrt{(36)/(25)}  or  x=-\sqrt{(36)/(25)}

x=(√(36))/(√(25))  or   x=-(√(36))/(√(25))

x=(6)/(5) or x=-(6)/(5)

x=1(1)/(5) or x=-1(1)/(5)
