Which of the following explains why f(x) = log4x does not have a y-intercept? Check all that apply.

Answers

The function f(x) = log4x does not have a y-intercept Because there is no power of 4 that is equal to 0.

What is a logarithm?

Exponentiation's inverse function is the logarithm. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.

The logarithm counts the number of times the same factor appears in repeated multiplication in the simplest case.

Following are the reason why f(x) = log4x does not have a y-intercept

1. There is no power of 4 that is equal to 0.

2. Its inverse does not have any x-intercepts.

3. f(x) approaches negative infinity.

Hence  f(x) = log4x does not have a y-intercept.

Answer:

8 crabs and 2 octopi

Step-by-step explanation:

Let c represent the amount of crabs and o represent the amount of octopi.

We can use this to set up a system of equations:

6c+8o=64

c=4o

We can solve this system using substitution. In this case, we can substitute 4o for c:

6(4o)+8o=64

24o+8o=64

Combine like terms

32o=64

Divide both sides by 32

o=2

Substitute 2 for o to solve for c:

c=4o=4(2)=8

There are 8 crabs and 2 octopi

The sum using summation notation will be - 312. The sum of the following progression is found by the formula as [tex]S_n = \frac{a(1 - r^n)}{(1 - r)}[/tex].

What is geometric progression?

Geometric Progression (G.P.) is a sort of sequence in which each successive phrase is obtained by multiplying the prior term by a set number known as a common ratio.

This progression is also known as a pattern-following geometric sequence of integers. Here you may also learn about mathematical progression.

A non-zero value is obtained by multiplying the common ratio by each phrase to obtain the next term 5 - 15 45 - 135.. is an example of a geometric series with a common ratio of -3.

The common ratio will be;

[tex]\rm r= \frac{-15}{3} \\\\ \rm r= -5[/tex]

The first term is 3

So  the sum using summation notation will be;

[tex]S_n = \frac{a(1 - r^n)}{(1 - r)} \\\\ S_n = \frac{3(1 - (-5)^4)}{(1 - (-5))} \\\\ S_n =- 312[/tex]

Hence the sum using summation notation will be - 312.

Please show how to do it, because I need to know how to do it again

Answers

Answer:

the system will be worth $1892.25 after 2 years.

Explanation:

as the value decreases: [tex]\sf A = P(1 - \frac{r}{n})^{nt}[/tex] ......notice the ' - '  as its *decreases*

given:

P = 2500n = 1 per year t = 2 yearsr = 13%

solve:

[tex]\sf A = 2500(1 - \frac{0.13}{1})^{1*2}[/tex]

[tex]\sf A = 1892.25[/tex]

another way of doing it easily is:

[ $2500 * (100- 13)% ] * (100- 13)% = $1892.25

P=2500r=13t=2

Use compound interest formula

[tex]\\ \rm\hookrightarrow P(1-r/100)^t[/tex]
