Saved Suppose that the population of deer in a state is 1,500 and is growing 2% each year. Predict the population after 4 years.
mestny [16]
<h2>Steps</h2>

So for this, we will be creating an equation using the exponential formula - which is y=ab^x (a = initial value, b = growth/decay).

Firstly, we know that the original population of the deer is 1,500 so that will be our a value.

Next, we know that the population is growing by 2% annually. With this, we will <em>add</em> 1 and 0.02 (2% in decimal form) since the population is <em>increasing</em>.

  • 1 + 0.02 = 1.02

1.02 will be our b variable. Now putting it together, our equation is: y=1500(1.02)^x

Now that we have our equation set up, plug 4 into the x variable and solve for y as such (Remember to not round until the very end):

y=1500*(1.02)^4\\y\approx 1624

<h2>Answer</h2>

<u>After 4 years, the deer population will be 1,624.</u>

A credit card bill for $559 was due on September 14. Purchases of $289 were made on September 19, and $15 was charged on Septemb
Sunny_sXe [5.5K]

Answer: $623

Step-by-step explanation:

calculation of Finance charge due on October 14

(+) $ 559 due on sep 14, $ 559 * (19.5*31) / (100 * 365) = $ 9.20

(+) purchase $ 289 on sep 19, $ 289 * (19.5*26 ) / (100 * 365) = $ 2.42

(+) finance charge on sep 28, $ 18 *(19.5*17 ) / (100 * 365) = $ 0.17

(-) Repayment on 25 sep , $ 250 * (19.5*20 ) / (100 * 365) = (2.745)

Total finance charges from 14 sep to 14 oct = $ 9.7= appr. 10

Amount due on 14 October = $559+$289+$15+$11.855- $250

= $ 623

Need help quickly plz
skad [1K]

Answer:

m<A = 20

Step-by-step explanation:

6y plus 3y = 9y

180 divided by 9 = 20

20x6=120

20x2=40

120+40=160

a triangle is equal to 180 so..

180-160=20

i did 6y + 3y because that line is 180 degrees ( half of a circle)

Explain why it is easier to graph an equation in slope intercept form than it is to graph an equation in standard form.
Allisa [31]
In slope intercept form you already have the y-intercept and the slope. all you have to do is plot the y-intercept and then plot the slope from that point.

hope this helps :)
