Answer:
P(t) = 200·0.95^t
Step-by-step explanation:
Each year, the population drops to 95% of its previous value. That is, the population is multiplied by 0.95 each year. Repeated multiplication is signified by an exponent. Here, that exponent is the number of years from today (t).
The population function can be written as ...
P(t) = 200·0.95^t
So first we need to find the total number of boxes that the cookies could fit in:
Now we know that 47 boxes were made from this amount of cookies.
If Mr. Riley sells each box for 8, then we need to multiply the number of boxes by 8:
So Mr. Riley will collect a total of 376 from selling all of his cookies.
Answer:
1. 6
2. 2
Step-by-step explanation:
1. 9-t=3(t-5)
9-t=3t-15
+t +t
9=4t-15
+15 +15
<u>24</u>=<u>4t</u>
4 4
6=t
2.5(5y+1)=10y-25
25y+5=10y-25
+25 +25
25y+30=10y
-25 -25
<u>30</u>=<u>-15y</u>
15 15
2=y
Sinα=h/d
h=dsinα, since d=10km and α=13
h=10sin13 km
h≈2.24951km
h≈2.2 km (to nearest tenth of a kilometer)
Answer:
when u divide both side by 2 the new equation will be y-5x=-3... and equation of a line is written in form of y=mx+c
so y=5x-3
