Question 5 (5 points)
(04.05 MC)
Which graph best represents the function f(x) = 4(1.5)x? (5 points)
Question 5 options:
1)
graph of increasing exponential function going through point 0, 2
2)
graph of increasing exponential function going through point 0, 3
3)
graph of increasing exponential function going through point 0, 1
4)
graph of increasing exponential function going through point 0, 4
Answers
Answer:
I am guessing the equation you meant to type is [tex]f(x)=4(1.5)^x[/tex]. Based on this information, I know that the answer is:
4) Graph of increasing exponential function going through point (0, 4).
Step-by-step explanation:
I graphed the function in Desmos, and I found that the y-intercept is (0,4). Answer choices 1-3 all have varying y-intercept options, while option number 4 says the graph is going through point (0,4) so we know that's the right answer.
I hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck with the rest of your assignment. I'll attach a photo of the graph below, so you understand the graph.
Answer:
I had the same exact problem on my quiz! The answer is D, because the y intercept is (0,4). Graphing the equation really helped me understand it! :)

Mr Hall sold 78 items at a car boot sale.
35% of his items did not sell,
How many items did Mr Hall have for sale?
Answers
A 35% decrease of (items he had for sale) is 78.
So 65% of (items he had for sale) is 78.
This means that 0.65 x ? = 78
We can work this out by doing 78/0.65 which is 120.
So I believe Mr Hall had 120 items for sale.
This is called reverse percentages if you want to watch some videos explaining it. Hope this helps!

The student council needs posters for the Winter Carnival. The print shop charges $15 for each print job. Each poster will cost an additional
$1.35.
Which equation shows the relationship between the number of posters, n, and the total cost, c, in dollars?
O A. c = 1.35n + 15
O B. n = 1.35n + 15
O C. c = 16.35n
O D. n = 16.35c
Answers
Answer: A. c = 1.35n + 15
Step-by-step explanation:
Given: Charge for each job = $15
Additional cost per poster = $ 1.35
Total cost = Charge for each job + (Additional cost per poster) (Number of posters) ...(i)
Varaibles:
c= Tota; cost for n posters.
Substitute all values in (i), we get
[tex]c=15+1.35n[/tex]
Hence, the required equation : c = 1.35n + 15
Hence, the correct option is A. c = 1.35n + 15.

Laura randomly pulled a marble from a bag and then replaced it.
• After 60 trials, she had pulled the color blue 25% of the trials.
• She had pulled red 15% of the trials.
• The remaining trials she pulled green.
How many times could Laura be expected to pull a green marble after 300 trials?
O A. 150
OB. 120
O C. 180
OD. 100
Answers
Answer: C. 180 times
Step-by-step explanation:
From the 60 trials, the percentage of times Laura picked a green marble was:
= 100% - Percentage of times blue and red were picked
= 100% - 25% - 15%
= 60%
If these results were repeated with 300 trials, the number of times Laura would be expected to pick green would be:
= 60% * 300
= 180 times

Here,
The population of butterflies in West Fremont is 60,000.
And, growing at a rate of 1.4% each year.
How to find interest?
Use compound interest formula [tex]A = P (1 + \frac{r}{100} )^n[/tex] to find interest.
Like in financial interest we have, [tex]A = P (1 + \frac{r}{100} )^n[/tex]
We have;
[tex]240000 = 60000 (1 + \frac{r}{100} )^n\\(1 + \frac{r}{100} )^n = \frac{24}{6} \\(1 + \frac{r}{100} )^n =4\\[/tex]
[tex]n ln (\frac{101.4}{100}) = ln (4)\\ n = \frac{ln 4}{ln 101.4 - ln 100}\\ n = 99.713[/tex]
Hence,
Year = 2004 + 99
So, In year 2103, the population will reach 240,000

This graph represents a transformation of the parent cube root function. Replace the values of h and k to create the equation of the transformed function.
Answers
The equation of the transformed function, y = ∛x+5 - 2
What is parent function?A parent graph is the graph of a relatively simple function. By transforming the function in various ways, the graph can be translated, reflected, or otherwise changed.
This graph represents a transformation of the parent cube root function.
Here, Parent cube root function is
y= ∛x
and the value of h and k is equal to 0
Now, as from the graph we can see that the graph changes direction at (-5,-2) which shows the graph is shifted 5 units to left and 2 unit down
Hence, the equation of the transformed function, y = ∛x+5 - 2

Samuel runs around a 1-mile track in 10 minutes, and Sophia runs around the same track in
10 minutes. Assuming they continue running at their respective speeds, how many total
miles will they run in 35 minutes? Express your answer as a mixed number.
Answers
Answer:
3.5 miles
Step-by-step explanation:
Step one:
given data
Samuel runs around a 1-mile track in 10 minutes
Samuel's speed is
speed= distance/time
speed= 1/10= 0.1 miles per minute
Sophia runs around the same track in 10 minutes
Hence Sophia's speed is also = 0.1 miles per minute
Step two:
Given that the time is 35 minutes, and their speeds are 0.1 miles per minute, we can find the distance from
speed= distance/time
distance= speed*time
distance= 0.1*35
distance= 3.5 miles

entrique uses a gift card to buy coffee at a coffee shop. The initial value of the guft cord is $20. The function n=20-2.75c represents the amount of money still left on the guft card n after c cups of coffee are bought. Find the zero of this function. Describe what this means in context.
Answers
Answer:
7 cups of coffee
Step-by-step explanation:
Given
[tex]n = 20 - 2.75c[/tex]
Required
Find and describe the zero of the function
To do this, we simply equate n to 0
i.e.
[tex]n = 0[/tex]
Substitute 0 for n in [tex]n = 20 - 2.75c[/tex]
[tex]0 = 20 - 2.75c[/tex]
Add 2.75c to both sides
[tex]0 + 2.75c = 20 - 2.75c + 2.75c[/tex]
[tex]0 + 2.75c = 20[/tex]
[tex]2.75c = 20[/tex]
Divide both sides by 2.75
[tex]\frac{2.75c}{2.75} = \frac{20}{2.75}[/tex]
[tex]c = \frac{20}{2.75}[/tex]
[tex]c = 7.273[/tex]
[tex]c = 7[/tex] --- Approximated
This implies that the maximum cups of coffees that can be bought is 7
