answer is D. last one
Answer:
D. All positive real numbers
Step-by-step explanation:
The range of a function f(x) are all the possibles values that f(x) can take. So in the function of the question it doesn't matter what value takes x, f(x) is always going to be a positive number. For example:
f(0)=[tex]4^{0}[/tex]=1
f(-1)=[tex]4^{-1}[/tex]=1/4
f(2)=[tex]4^{2}[/tex]=16
Then, the range of f(x) is all positive real numbers.

What is the fourth term in the arithmetic sequence 13,10,7
Answers
The fourth term in the arithmetic sequence 13, 10, 7 is 4.
Explanation:The arithmetic sequence 13, 10, 7 has a common difference of -3. To find the fourth term, we can start with the first term and keep subtracting the common difference. So, 13 - 3 = 10, 10 - 3 = 7, and 7 - 3 = 4. Therefore, the fourth term in the arithmetic sequence 13, 10, 7 is 4.

Andrew is planning a tailgate party before the big football game. He has budgeted a maximum of $60 for hamburgers and hot dogs. Hamburgers cost $3 per pound, and hot dogs cost $2 per pound. Write an inequality to describe the possible number of pounds of hamburgers and of hot dogs he can purchase.
Answers
The inequality that describes the the possible number of pounds of hamburgers and of hot dogs he can purchase is 3x + 2y ≤ 60.
We have,
Let x be the number of pounds of hamburgers that Andrew purchases, and let y be the number of pounds of hot dogs that he purchases.
The cost of x pounds of hamburgers is 3x dollars, and the cost of y pounds of hot dogs is 2y dollars.
According to the problem, Andrew has budgeted a maximum of $60 for hamburgers and hot dogs.
Therefore, we can write the following inequality:
3x + 2y ≤ 60
This inequality describes the possible combinations of x and y that Andrew can purchase, such that the total cost of hamburgers and hot dogs does not exceed his budget of $60.
Thus,
The inequality that describes the the possible number of pounds of hamburgers and of hot dogs he can purchase is 3x + 2y ≤ 60.

Solve your formula from problem 12 for m. Then find the taxi driver’s hourly rate of his pickup rate is $2 and he charges $19.50 for a 7 - mile trip
Answers
Answer: Cost per mile m = $4.78.
Step-by-step explanation:
Since we have given that
Pick up rate = $2
Charges for a 7 mile trip = $19.50
Charges for a mile trip would be
[tex]\dfrac{19.50}{7}\\\\=2.78[/tex]
So, amount of taxi's drivers is given by
[tex]\$2.78+\$2\\\\=\$4.78[/tex]

Juan's baseball card collection was worth 800$. Over the last 5 years,thw collection decreased $300 in value. What integer representa the average decrease in value each year.
Answers
Final answer:
The average yearly decrease in the value of Juan's baseball card collection, which decreased by $300 over 5 years, is $60. This integer represents the yearly reduction in value.
Explanation:
Juan's baseball card collection was worth $800. Over the last 5 years, the collection decreased by $300 in value. To find the average decrease in value each year, we can use the formula: Average decrease per year = Total decrease / Number of years.
Given that the total decrease is $300 and the time period is 5 years, the calculation would be:
Average decrease per year = $300 / 5 = $60.
Therefore, the integer that represents the average decrease in value each year for Juan's baseball card collection is $60.

Maria wrote the equation of a line that has a slope of 4/3and passes through point (3, 5). Which statement is true?
Answers
Answer:
B
Step-by-step explanation:
The slope intercept equation is [tex]y=\frac{4}{3}x+1[/tex] is true statement. Option C is correct.
From the given information the slope of the line is 4/3 and it is passing through point (3, 5).
Now, determine the equation of line in slope intercept form.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
To find the equation, first find the y intercept by considering the point values (3, 5).
[tex]5 = \frac{4}{3}+b[/tex]
[tex]5=4+b[/tex]
[tex]b=1[/tex]
Now plug in the values of slope and y intercept in slope intercept form:
[tex]y=\frac{4}{3}x+1[/tex]
Hence, Option C is correct, he equation of the line is [tex]y=\frac{4}{3}x+1.[/tex]

What is a number greater than 1,000 whose prime factorization contains 1 prime number that does not repeat, 1 prime number that repeats three times, and 1 prime number that repeats twice
Answers
So for the prime number that doesn't repeat, you can just say a random prime number, say like 7.
For the prime number that repeats 3 times, say like 11.
And the prime number that repeats twice, you can just say something like 13.
Then it would be 7 * 11 * 11 * 11 * 13 * 13, which the solution would be 1,574,573, above 1000.

A percentage is a way to describe a part of a whole. The retail price of a couch at a furniture store that has a wholesale price of $115 and is marked up by 75% is $201.25.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the wholesale price of the couch at a furniture store is $115. Now, as the retail price is marked up by 75%, therefore, the new price of the couch can be written as,
The new price of the couch = 175% of the wholesale price
= 1.75 × $115
= $201.25
