Remark

If you just focus on the gray ones for a moment.

The series goes up 0 2 4 6

6 is in the fourth figure so you can count by figures.

f(n) = 2*(n - 1) So for the fourth figure, for example, you get f(4) = 2*(4 - 1) = 2 * 3 = 6 which is just what we see.

So far, the nth figure is f(n) = 2*(n - 1) But there is still 1 red one to account for.

Now we get f(n) = 2(n - 1) + 1 or 2n - 2 + 1 or 2n - 1.

Answer: f(n) = 2n - 1 <<<<< answer

ruslelena [56]

If Jackson went to the movies and payed $7 initially for his ticket and then payed $2 for each box of candy that he buys, then the equation could look like this: y = 2x + 7, where y represents the total cost and x represents the number of boxes of candy Jackson buys.

The coffee Lily likes is composed of 97.3% water and 2.7% cocoa. The coffee John likes is composed of 96% water and 4% cocoa. Ho

mestny [16]

30 ounces of the coffee John likes consists of

$0.96\cdot30=28.8$ ounces of water
$0.04\cdot30=1.2$ ounces of cocoa

To this mixture we're adding $x$ ounces of water, so that the new mix has a total volume of $30+x$ ounces and matches the composition of the coffee Lily likes. This means it would consist of

$0.973\cdot(30+x)=28.8+x$ ounces of water
$0.027\cdot(30+x)=1.2$ ounces of cocoa (same amount of cocoa as before because pure water is being added)

Solve for $x$ :

$0.973(30+x)=28.8+x\implies29.12+0.973x=28.8+x$

$\implies0.39=0.027x$

$\implies x\approx14.4$

###

Just to confirm: the new mixture consists of

$28.8+14.4=43.2$ ounces of water
$1.2+0=1.2$ ounces of cocoa

giving a total volume of $43.2+1.2=44.4$ ounces of coffee, and $\dfrac{43.2}{44.4}\approx0.973$ , as required.

The balance owed on your credit card triples from $700 to $2100 in 12 months. If the balance is growing linearly then it would t

Fofino [41]

Answer:

If the balance is growing exponentially the balance after 45.4 months will be $44,925.94.

Step-by-step explanation:

The exponential growth equation is:

$f(x)=700(1+0.096)^{x}$

Compute the value of f (x) for <em>x</em> = 45.4 as follows:

$f(x)=700(1+0.096)^{x}$

$=700(1+0.096)^{45.4}\\\\=700\times (1.096)^{45.4}\\\\=700\times 64.1799181\\\\=44925.94267\\\\\approx 44925.94$

Thus, if the balance is growing exponentially the balance after 45.4 months will be $44,925.94.
