Step-by-step explanation:
Below is a graph of p, an insect population, w weeks after it was first measured. The population grows exponentially.
Write an approximate domain and range for this situation.
Write an equation relating p and w.
The range and the domain of the graph are the sets of non-negative real numbers, while the equation relating p and w is [tex]p = 300 * 3^w[/tex]
From the graph, we have the following ordered pairs
(1,900) and (3,8100)
An exponential function is represented as:
[tex]p = ab^w[/tex]
At the point (1,900), we have:
ab = 900
At the point (3,8100), we have:
ab^3 = 8100
Divide both equations
[tex]\frac{ab^3}{ab} = \frac{8100}{900}[/tex]
Evaluate the quotients
[tex]b^2 = 9[/tex]
Take the square roots of both sides
b = 3
Recall that:
ab = 900
So, we have:
3a = 900
Solve for a
a= 300
Hence, the equation is:
[tex]p = 300 * 3^w[/tex]

Answer:
27
Step-by-step explanation:
Answer:
$27
Step-by-step explanation:
substitute the value of p (price of the package of henna powder) which has been given as $12 and the value of s (price of the squeeze bottle) which has been stated as $3 into the equation from part b).
since the equation is 3(p-5) + 2s
write 12 instead of p, and 3 instead of s.
then solve the equation.
= 3(12-5) + 2(3)
= 3(7) + 2(3)
= 21 + 6
= 27

To rent a certain meeting room, a college charges a reservation fee of $19 and an additional fee of $4 per hour. The chemistry club wants to spend at most $47 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Answer:
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Step-by-step explanation:
h=hours
19+4h=47
Subtract 19 from both sides of the equation.
4h=28
Divide 4 from both sides of the equation.
h=7
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Hope this helps :)
Answer:
7 hours
Step-by-step explanation:
There is $47 total dollars. The reservation fee is $19 dollars. Subtract the two:
47-19= 28 dollars
Now the per hour fee is 4 dollars an hour. And you have 28 hours. So divide the two to get maximum hours:
28/4=7 hours

The sum of two numbers is 91. The smaller number is thirteen less than the larger number. Find both numbers.
x - large number
y - small number
Answer:
x=52 and y=39
Step-by-step explanation:
52 + 39 = 91
52 - 13 = 39
What you would do is make the equation:
91=X+(X-13)
Then, you would solve for X and once you find X, you would subtract 13 from it.
The answers should be 52 and 39.

help pls and letter d is 4 1/2
Answer: The answer is B.
Step-by-step explanation:
To figure out, you must first turn the mixed fraction (3 1/2) into an improper fraction (7/2). We can do so by:
3 * 2 = 6
6 + 1 = 7 or 7/2
Next, you follow the rules of KCF: Keep, Change, Flip. Keep the first fraction, Change the sign to its inverse operation, and Flip the second fraction.
Our original equation is 7/2 /(divided by) 3/2 = ?
1. Keep the first fraction
7/2 / 3/2 = 7/2 / 32
2. Change the sign to its inverse operation
7/2 / 3/2 = 7/2 * 3/2
3. Flip the second fraction
7/2 * 3/2 = 7/2 * 2/3
Now, solve.
7/2 * 2/3
7 * 2 / 2 * 3 = 14/6
To make this a proper mixed number, first simplify.
14/6 / 2 = 7/3
Now, figure out how many wholes are in 7/3.
7/3 / 3 = 2 1/3
This is because 2 times 3 is six, and 7 minus 6 equals 1, or 1/3.
Therefore, the answer is 7/3 OR 2 1/3 OR B
A cell phone company charges a monthly fee of $50 for 300 minutes. Each addition minute costs $0.05. Determine if the function is linear or no linear and explain your reasoning.
Answer:
linear
Step-by-step explanation:
The graph would be linear since it's .05 every minute, which would mean that every minute it would cost .05 --> adding up minutes. The flat fee at the beginning is trying to trick you up, don't get fooled ;)

Answer: 29.5 inches tall.
Step-by-step explanation:
If Eva was 1.5 inches taller than her original height, she would be half of Maria’s height. So, we divide Maria’s height by two to find the height Eva would be if she was 1.5 inches taller.
62 / 2 = 31 inches
Next, to find Eva’s real height, we subtract 1.5 inches from the 31 inches. This is because Eva would only be half Maria’s height IF she was 1.5 inches taller, but she is not, so therefore we can deduct it.
31 - 1.5 = 29.5 inches
Therefore, Eva’s height is 29.5 inches tall. We can prove this, as well.
29.5 + 1.5 = 31 inches
31 * 2 = 62 inches
Therefore, Eva is 29.5 inches tall.

i. Statements b and d would map Shape l onto Shape IIii. Statements a, c, e, and f does not map Shape l onto Shape IITransformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation.Translation is a method that requires moving every point in a given shape in the same direction and same unit.
Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased.Thus the answers to the question are listed as follows:

Max is already 224 miles into his road trip. If he is averaging 52 miles per hour and the trip is 640 miles total, how many more hours does he have left to drive?
x - hours left to drive
Answer:
8 hours.
Step-by-step explanation:
1. Subtract 640-224=416
2. Divide 416/52
3. 8 hours
8 hours.
Step-by-step explanation:
We have been given that Max is averaging 52 miles per hour and the trip is 640 miles total. Max is already 224 miles into his road trip.
Let us find the remaining distance of trip by subtracting the distance already covered from total distance.
Remaining Distance = 640 miles - 224 miles
Remaining Distance = 416 miles
We will use formula: Time = Distance/Speed to find the number of hours Max still have to drive.
Time = 416 miles/52 miles/hour
Time = 416 miles/52 × hour/miles
Time = 416/52 hour
Time = 8 hours
Therefore, Max have left 8 more hours to drive.
