Answer:
left relation only
Step-by-step explanation:
The left relation is a function since each number of the left set is used only once.
In the middle relation, the -9 is used twice. In the relation at the right, the 0 is used twice. That makes those two relations not functions.

You are applying for a fuel tax rebate. The amount of fuel road tax is 32 cents per gallon. If the refund is 50 % of this amount, what is the refund for 8,000 gallons of fuel?
Answers
Answer: $1,280
Step-by-step explanation:
The refund one a gallon is 50% of the cost of the gallon which is $0.32.
The refund on a gallon is:
= 50% * 0.32
= $0.16
If it was for 8,000 gallons the refund would be:
= 8,000 * 0.16
= $1,280
6. The number of bacteria N in a culture is given by the model N(t) = 250e 0.0156 where t is the time in hours.
Find how many hours it takes for the original population to double. Round your answer to the nearest hundredth
of an hour.
i just need to know how to work this out!! please help
Answers
Answer:
t ≈ 44.43 hours
Step-by-step explanation:
Expression that models the population of a bacteria after time 't' is,
N(t) = [tex]250(e^{0.0156t})[/tex]
Here initial population = 250
And N(t) = Population after 't' hours
t = duration
We have to find the duration in which bacterial population gets doubled.
N(t) = 2×250 = 500
From the given expression,
500 = [tex]250(e^{0.0156t})[/tex]
[tex]e^{0.0156t}=2[/tex]
[tex]\text{ln}(e^{0.0156t})=\text{ln}(2)[/tex]
0.0156t[ln(e)] = 0.693147
0.0156t = 0.693147
t = [tex]\frac{0.693147}{0.0156}[/tex]
t = 44.432
t ≈ 44.43 hours

Answer:
The most feasible answer would be the first option - 47
Step-by-step explanation:
This is true because if we look at the triangle it looks as if the sides have equal length, but if we look closely we will notice that the b side is angled more by a slight inch, compared to the other side, thus your answer should be 47 - the first option

A ball is thrown into the air with an initial upward velocity of 48 ft/s. It height h in feet after t seconds is given by the function h (t)=-16t^2+48t+4.
In how many seconds will the ball reach its maximum height?
Answers
Answer:
Step-by-step explanation:
h(t)=-16t^2+48t+4
dh/dt=-32t+48
d2h/dt2=-32
Since acceleration is always negative when the velocity, dh/dt=0, it will occur at the maximum height.
dh/dt=0 when
-32t+48=0
-32t=-48
t=1.5 seconds
Without calculus, the vertex of a parabola will be at -b/(2a) of the quadratic equation. In this case
-48/(2(-16))
-48/-32
1.5 seconds
