Answers:
- All values of t must be positive
- A viable solution is (10, 50)
- All values of t must be positive.
EXPLANATION
t, temperature (in Fahrenheit) is dependent on c
c is the number of cricket chirps heard in 14 seconds
Therefore, all values of c must be positive integers
If all values of c must be positive integers
Then all values of t must also be positive integers
- A viable solution is (10, 50).
EXPLANATION
t = c + 40
Since 10 is a positive integer, it is a possible value for c
If c = 10
t = 10 + 10
t = 50
Therefore a viable solution is (10, 50)
EXPLANATION FOR WHY OTHER OPTIONS ARE WRONG:
- The graph is continuous.
This is WRONG because this function only allows the values of c to be only certain points in the interval (only positive integers). Therefore, it is a discrete function.
- A viable solution is (–2, 38)
This is WRONG because the -2 is a negative integer, and the value of c cannot be a negative integer.
- A viable solution is (0.5, 40.5)
This is WRONG because 0.5 is not an integer, and all values of t must also be positive integers.
Answer:
Step-by-step explanation:
Let the box be y
75% of y = 27
75/100 × y = 27
75y/100 = 27
75y = 27 × 100
75y = 2700
y = 2700/75
y = 36

Answer:
r = 0.073/12 ≈ 0.0060833...
Step-by-step explanation:
In the given amortization formula, the interest rate (r) is the rate for one payment period.
<h3>Period interest rate</h3>
The given 7.3% interest rate is presumed to be a nominal annual interest rate. Since there are 12 months in a year, the corresponding monthly interest rate is ...
7.3%/12 = 0.073/12 ≈ 0.00608333...(repeating)
The value of r that goes in this formula is 0.0608333...(repeating).
Answer:
Number of cards at week n = 10,000(0.85)^(n-1).
At week 6 Dylan has 4437 cards.
Step-by-step explanation:
At the start of week 1 he had 10,000 = 10,000(0.85)^0 cards.
So at the start of week 2 he had 10,000(0.85)^(2-1) cards.
Number of cards for week n = 10,000(0.85)^(n-1).
Number of he will have at the start of the 6th week
= 10,000(0.85)^(6-1)
= 4437 cards (answer).
