Answer:
39/50 and 0.78
Step-by-step explanation:
78% = 78/100 (or 78 hundredths) = 0.78
39 ÷ 50 = 0.78
Answer:
<em>it is the last one </em>
Step-by-step explanation:
<em>Since a function is based on a set of ordered pairs, where the first element in each pair is from the domain and the second is from the codomain. Also A function is a mapping from a set of inputs (the domain) to a set of possible outputs (the codomain). </em>
<em>The last one doesn't show the correct inputs and outputs</em>

Answer:
3/4
Step-by-step explanation:
Answer: The general formula for exponential sequence or GP is
GP = arn-1 , ie ar raised to the power of n-1 where a is the first term , r is the common ratio and n is the number of terms. Now to find the 14th term we first find the common ratio (r) by dividing the second term by the first term of third by second term.
r = -10/5
=. -2.
Since n is 14-1 = 13. and a is 5
we now put those values in the formula to find the 14th term
T14 = ar^n-1
= 5 x (-2)^13
= 5 x -8192
=. -40,960
There the 14th term of the GP sequence
= -40,960
Step-by-step explanation:
Answer:
Where b is the decay rate for this case. Using the condition given we have:
And our model would be given by:
And replacing the value of t=15 we got:
Step-by-step explanation:
For this case since the half life is 6 hours we have the following condition:
Where 
is the initial amount
Our model for this case is given by this expression:
Where b is the decay rate for this case. Using the condition given we have:
And solving for b we got:
And solving for b we got:
And our model would be given by:
And replacing the value of t=15 we got:
