Its 5 divided my 7.50 since each decided to pitch in to help by the pie
Answer:
<h2 />
Step-by-step explanation:
Given the half like of a material to be 8.3 hours and the amount of iron-52 left after t hours is modeled by the equation 
, we can get A(t) as shown;
At t = 8.3 hours, A(8.3) = 1/2
Initially at t = 0; A(0) = 1
Substituting this values into the function we will have;
One way to find out is to subsiute the points and find which ones are true
the points are (3,2) and (-2,-1)
subsiute 3 for x and 2 for y, then -2 for x and -1 for y
y-3=3/5(x-2)
2-3=3/5(3-2)
-1=3/5(1)
-3=3/5 false
-3x+5y=1
-3(3)+5(2)=1
-9+10=1
correct
try the other
-3(-2)+5(-1)=1
6+-5=1
true
one answe ris B
3/5x+1/5
this is incompleteso I can't solve it
maybe it was supposed to be 3/5x+1/5=y, but I don't know
y+1=3/5(x+1)
2+1=3/5(3+1)
3=3/5(4)
3=12/5
false
the answe ris B (maybe C but I con't know)
Answer:
S(x)=42000 * 1.04^x
Step-by-step explanation:
now = 42000
in 1 year = 42000 *1,04, because 4% increase is to multiply 1,04
in 2 years = 42000 *1,04*1.04 = 42000*1.04^2
in x years = 42000 * 1.04^x
1.37 : 7.66
or
1.37/7.66 as a fraction
