Answer:

It's called the Natural Logarithm because so many processes in nature can be described mathematically using it.

For example:

1) The population of a colony of rabbits that reproduce at a constant rate

2) The decay rate of a charged capacitor

3) The decay rate of a radioactive isotope

4) The rate at which your money will grow if you apply an interest rate continuously over a period of time.

5) The population of seeds in a sun flower

6) etc.

Answer:6080$

Step-by-step explanation:I did the same question on my test

7.25% of 38,000

10% = 3,800

5% = 1,900

1% = 380

0.50% = 190

0.25% = 95

1,900+380+380+95 = 2,755

38,000+2,755 = 40,755

Answer:

b

Step-by-step explanation:

The function represented by the graph is

y = { x² + 6 , x < 3

        -x + 6 , x ≥ 3}

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

According to the graph

When x < 3 then  y =  + 6

and, at x = 3 we get an open interval.

So, y = x² + 6 is valid for x < 3 not at x =3.

Also , y = -x + 6 is valid for x ≥ 3 and we get a close interval.

Thus, the function represented by the graph is

y = { x² + 6 , x < 3

        -x + 6 , x ≥ 3}

Answer:

  B

Step-by-step explanation:

Euler's formula tells you that ...

  cos(θ) +sin(θ)·i ≡ e^(i·θ)

__

So, for θ = 90° (= π/2 radians), this is ...

  cos(π/2) +sin(π/2)·i = 0 +i = i = e^(i·π/2) . . . . . matches choice B

The number of ways Dr. Orchid can arrange all 9 paintings and 4 paintings is, 362880 and 126 respectively.

Arrangement of the things or object is mean to make the group of them in a systematic order, in all the possible ways.

The number of possible ways to arrange is n!. Here, n is the number of objects.

Dr. Orchid has 9 paintings she wants to hang side by side on her wall.

There are total 9 paintings. So the number of arrangement of these painting is,

[tex]9!=9\times8\times7\times6\times5\times4\times3\times2\times1\\9!=362880[/tex]

There are total 9 paintings, in which Dr. Orchid wants to display 4 of the paintings.  Thus, the number of ways can she choose the paintings she wishes to display is,

[tex]^9C_4=\dfrac{9!}{4!(9-4)!}\\^9C_4=\dfrac{9\times8\times7\times6\times5!}{4!5!}\\^9C_4=126[/tex]

Hence, number of ways Dr. Orchid can arrange all 9 paintings and 4 paintings is, 362880 and 126 respectively.

Answer:

2:3:4=40,000:60,000:80,000

Step-by-step explanation:

plus 2+3+4

thats 9

divide 9 by total amount which is what ratio 1 got =20,000

so now you multiple each ratio with 20,000 to get the ratio.

Answer:

60 gallons

Step-by-step explanation:

so he enlarged it by three so it would be 24by30

because of that, you have to multiply 20g by 3 also

that gives you 60 gallons

Answer:

2 x 30   cm

Step-by-step explanation:

L x W = 60

(2x-12)(3x+9) = 60

 6x^2 -18x-168=0

use quadratic fromula to find   x = 7   or -4 (throw out)

the sides then become   ( using 7)    

 2   and 30   cm  

Firstly this looks like translated log function graph

log1=0

As per graph the graph is pulled some inwards y axis but little bit

Usually log x leaves y axis at -1 but here it leaves at +2

So

y axis is moved upwards (+3)
