Which substance is a mixture?<br> salt<br> gasoline<br> aluminum<br> carbon dioxide
pogonyaev
First, we must understand why the three other choices are not mixtures. Salt is a compound made from elements Sodium and Chlorine. Aluminum is an element. Carbon dioxide is also a compound composed of Carbon and Oxygen. Now, gasoline. is substance made from refined crude oils (or hydrocarbons). As a matter of fact, gasoline is an example of a homogenous mixture. Thus, amongst the choices, the mixture would be gasoline<span>. </span>

Create three new exponential equations to represent Alison, Cindy, and Javier. Alison loves social media and likes for her posts
k0ka [10]

The new exponential equations to represent Alison, Cindy, and Javier would be 1/(1+e^-x) representing an s curve showing a lot of growth.

<h3>What is an exponential equation?</h3>

The exponential function is a mathematical function denoted by f(x)=\exp or e^{x}.

Here, he new exponential equations to represent Alison, Cindy, and Javier would be 1/(1+e^-x) representing an s curve showing a lot of growth while Cindy and Javier would be ln(x) and x^(1/2) as they will grow somewhat fast at first and then die out.

Find the value of $1000 deposited for 10 years in an account paying 6% annual interest compound
Romashka [77]

Answer:

You have to use the formula for compound interest which is: A=P(1+r/n)^nt

The Givens info is:

A=?

P=1000

r= 6% = 0.06 (convert into decimal)

n=12(# of interest periods: since it is monthly n=12)

t=10

Now your formula should look like this:

A= 1000*(1+(0.06/12))^12*10

A=1000*(1.005)^120

A=1000*(1.819396734)

A=$1819.40

The number of electrical outages in a city varies from day to day. Assume that the number of electrical outages ( x ) in the cit
svlad2 [7]

Answer:

0.26 and 0.577

Step-by-step explanation:

Given :

x :___0 ___ 1 ____ 2 ____ 3

f(x):_0.80 _0.15__0.04 __0.01

The mean :

E(X) = Σ(x * p(x))

E(X) = (0*0.8) + (1*0.15) + (2*0.04) + (3*0.01)

E(X) = 0 + 0.15 + 0.08 + 0.03

E(X) = 0.26

Var(X) = Σx²*p(x)) - E(x)²

Σx²*p(x)) = (0^2*0.8) + (1^2*0.15) + (2^2*0.04) + (3^2*0.01) = 0.4

Σx²*p(x)) - E(x)² = 0.4 - 0.26² = 0.3324

Std(X) = √0.334 = 0.577

If Sin 3x= Cos (x-60), find the value of x​
Kamila [148]

Answer:

x = 15

Step-by-step explanation:

Assuming 3x and x-60 are in degrees, you can use:

cos(a) = sin(a+90)

To rewrite the equation as:

sin(3x) = sin(x-60+90)

sin(3x) = sin(x+30)

3x = x+30

2x = 30

x = 15

But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
