A marine biologist is studying the growth of a particular species of fish. She writes the following equation to show the length of the fish, f(m), in cm, after m months:
f(m) = 4(1.08)m
Part A: When the marine biologist concluded her study, the length of the fish was approximately 6.86 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(m) represent? (2 points)
Part C: What is the average rate of change of the function f(m) from m = 3 to m = 7, and what does it represent? (4 points)

Answer:
0 ≤ m ≤ 70.4541 cm/month; average rate of growth over last 4 months of studyStep-by-step explanation:
Part A:
The study was concluded after 7 months. The fish cannot be expected to maintain exponential growth for any significant period beyond the observation period. A reasonable domain is ...
0 ≤ m ≤ 7
__
Part B:
The y-intercept is the value when m=0. It is the length of the fish at the start of the study.
__
Part C:
The average rate of change on the interval [3, 7] is given by ...
(f(7) -f(3))/(7 -3) = (4(1.08^7) -4(1.08^3))/4 = 1.08^3·(1.08^4 -1)
≈ 0.4541 cm/month
This is the average growth rate of the fish in cm per month over the period from 3 months to 7 months.

HELP PLEASE I DON´T UNDERSTAND RATIOS!
Answers
Answer:
Jake made 7 bead strings
Step-by-step explanation:
The ratio is 2:6 next would be 4:12 then 6:18 and so on. You just add what you started with to the corresponding side. 8:24, 10:30, 12:36, 14:42. The right side is 3x the left side.
Answer:
Step-by-step explanation:
You don't really need to use ratios for this question. You need to understand that for each necklace he uses 2 red and 6 whites.
Let the number of necklaces he can make = x
The total number of beads = 56
2x + 6x = 56
8x = 56 Divide by 8
8x/8 = 56/8
x = 7
So the number of necklaces possible is 7.
If you insist on doing this with ratios then you could do it as
2/8 = x/56 What this means is that 2 reds to the total = x / 56. The 56 is the total number of beads used. The x represents the number of reds.
2/8 = x/56 Cross multiply
2 * 56 = 8x Divide both sides by 8
2 * 56/8 = x
x = 14.
That means of the 56 beads used, 14 of them are red.
6/8 = y / 56 Cross multiply
6*56 = 8y
336 = 8y Divide by 8
336/8 = 8y/8
y = 42
This means that 42 beads were white
The total is 56. But here's the catch. The highest prime common to both is 7 and that's how many necklaces can be made.

Working simultaneously, four fudge machines complete a big order in 32 hours. All the machines at the fudge factory work at the same pace. How many hours would it take to complete the order with twice the number of working machines?
Answers
Answer:
4 Hours
Step-by-step explanation:
Let's say that the rate of the machines 1/x, because every time they complete an order, it takes them x hours. To find x, we have to add the the rates of the individual machines, which would equal the rate of the machines working together. We know that there are four machines working together at the same rate, and it took them 32 hours.
So:
1/x + 1/x + 1/x + 1/x = 1/32
1/4x = 1/32
4x = 32
x = 8
Thus, the rate of the machines is 1/8.
Now we have to find the time of the order with only half of the machines working together. This time, we don't know the combined rate, so I'll substitute it for y.
1/8 + 1/8 = 1/y
1/4 = 1/y
y = 4
The time taken to complete it is 4 hours.

equation of line M is Y=5/8x+1 . Line N is perpendicular to M. What is the slope of line N?
Answers
Step-by-step explanation:
the slope of a line is always the factor of x in the equation. in our case here : 5/8.
the slope is the y/x ratio indicating how many units y changes, when x changes by a certain amount of units (e.g. when going from one point on the line to another).
the perpendicular slope (crosses the original line in a right angle = 90 degrees) turns x and y upside-down and flips the sign.
so, in our case, it is -8/5.

A line with a slope of 5 passes through the points (4,5) and (5,u) What is the value of u?
Answers
Answer:
See Below
Step-by-step explanation:
Slope is rise over run.
Rise is the difference in the y values
Run is the difference in the x values.
Rise/Run = 5 (slope)
You have both x values 4 from one point and 5 from the other point so the difference is 1. The Run is equal to 1
So you now have Rise / 1 = 5
The first y value you have is 5 and based on (rise/1 = 5), you know the difference in the y values must equal 5. That means the other y value has to be either 10 or 0.
0 will not work because that would make the slope negative since the line would slope downward from left to right.

Using the slope formula to calculate the slope (m):
m = [tex]\frac{y2-y1}{x2-x1}[/tex]

= (0+2)/3
= 2/3
Hence, the slope (m) is 2/3.
