Hello,
Answer D 5/4
since div 15={1,3,5,15}
and div 8={1,2,4,8}
posiible rational root is a*b where a∈div 15 and b∈div 8
50,000 ÷ 2,500 = 20 bolts
2,500 ÷ 2,500 = 1 ton
20 bolts: 1 ton
20 × 500 = 10,000 more bolts
Hope this helps!
This is the concept of application of exponential growth, suppose in 1990 time,t=0 and in 1990 time,t=9. Using the exponential growth formula given by:
f(t)=ae^(kt)
thus substituting the value we get:
40=37e^(9k)
this can be written as:
(40/37)=e^(9k)
introducing the natural logs we get:
ln(40/37)=9k
hence;
k=1/9ln(40/37)=0.0087
Therefore our formual will be given by:
f(t)=37e^(0.0087t)
N/B: The population is in millions. Thus to get the population in 2016 we shall proceed as follows;
t=26
thus
f(t)=37e^(26*0.0087)
f(t)=46.35 million
Answer: 4
explanation: the rule is 4x = y
if you plug in the x-value 0 for 4(x)=y, then you would get the y-value 0
which makes it (0,0)
and then plug in the other x values 3 and 9:
4(3) = 12
(3, 12)
4(9) = 36
(9, 36)
