Write an exponential growth function, and then describe a real-world situation that the
function could represent. Do the same for an exponential decay function. Share your
functions and the situations they represent.
Answer:
Step-by-step explanation:
Exponential growth function can be represented as follows
y =
Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or
dy / dt =by , or rate of increase depends upon y itself
dy / y = bdt
integrating on both sides
lny = bt
y =
It represents very fast increase in y .
The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.
For exponential decay function
y =
The decay of a radioactive material is an example of exponential decay function.
Answer:
Exponential growth function can be represented as follows
y =

A vine grows 7.5 feet every 5 days. Is the length of the vine on the last day proportional to the number of days of growth? Explain.
Answer:
yes since it grows at a constant rate at 7.5 feet/5 days so it should be proportional if you treat it as an algebraic equation and solve for the rate of 1 day's growth but that gives an assumption that no factors would affect the growth and it'll always grow at that exact rate
Step-by-step explanation:

At a music store, the price of a set of speakers is $245, plus the sales tax of 6.5%. What is the total cost of the speakers, including the sales tax?
Answer:
$260.93
Step-by-step explanation:
$245 x 6.5% = $15.925 Tax
$15.925 rounds to $15.93
$245 + $15.93 = $260.93

Answer: Joe is right
Step-by-step explanation:
Joe is right because he said that the two points are different and he is right because the difference is that Point P is a negative number and that Point Q is a positive, even though they are both just opposites Joe would still be right.
Answer:
Tim is correct.
Step-by-step explanation:
When looking at absolute value, a number that is negative becomes positive so both fractions would be the same

−8⋅f(1)−4⋅g(4)= Help me please!!
Answer: -8
Step-by-step explanation:
−8 * f(1) −4 * g(4)
= -8 * (-2) -4 * 6
= 16 - 24
= -8
The calculated value of the given expression is "-8f-16g" following are the calculated steps for the given expression:
Expression calculation:= −8 × f(1) −4 × g(4)
= −8 × 1 × f −4 × 4 ×g
= −8f −16g
Explanation of the evaluation of the expression:
In the above-given expression the value of f(1) will be "1 × f", and similarly the g(4) the value will be equal to "4 × g" that's why the calculated value of the given expression will be equal to "−8f −16g".So, the final evaluated value of the given expression will be "−8f −16g".

The formula for any geometric sequence is an = a1 · rn - 1, where an represents the value of the nth term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the sequence -3, -6, -12, -24, ...?
an = -3 · 2 n - 1
an = -3 · (-2) n - 1
an = 2 · (-3) n - 1
an = -2 · (-3) n - 1
Answer: an = -3 · 2^n - 1
Step-by-step explanation:
In a geometric series, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
an = a1 × r^(n - 1)
Where
a1 represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
Looking at the given sequence,
a = - 3
r = - 6/ - 3 = 2
Therefore, the formula for the sequence is
an = - 3 × 2^(n - 1)

Elena has some bottles of water that each holds 17 fluid ounces. How much water is in 51 bottles??
Answer:
867 fluid ounces
Step-by-step explanation:
51 bottles x 17 fluid ounces per bottle equals 867 fluid ounces
Multiply 51 by 17.
51 x 17 = 867 ounces.
1 gallon = 128 ounces
867/128 = 6 gallons and 99 ounces

Matt is making cookies. He adds fraction 3 over 4 of a cup of sugar to a bowl. He then removes two fraction 1 over 8 cups of sugar. Which of the following best explains the amount of sugar left in the bowl?
fraction 3 over 8, because fraction 3 over 4 minus 2 times fraction 1 over 8 equals fraction 3 over 4 minus fraction 2 over 8
fraction 3 over 8, because fraction 3 over 4 minus 2 times fraction 1 over 8 equals fraction 3 over 4 minus fraction 3 over 8
fraction 4 over 8, because fraction 3 over 4 minus fraction 2 times 1 over 8 equals fraction 3 over 4 minus fraction 3 over 8
fraction 4 over 8, because fraction 3 over 4 minus 2 times fraction 1 over 8 equals fraction 3 over 4 minus fraction 2 over 8.

Pablo purchased adult and youth tickets for the football game. He bought x adult tickets for $74 each and y youth tickets for $35. Write an expression that can be used to show the total cost, C, of all tickets. (4 points) a C = (74 + 35)x b C = (74 + 35)(x + y) c C = 74y + 35x d C = 74x + 35y
Answer:
c=74x+35y (answer c)
Explanation:
The adult tickets are x and the youth tickets are y. They are not influenced by but add up to the total coast.
A does not work because it is 35+74 multiplied by the amount of tickets needed for adults. B does not work because it mulitplies the cost of tickets by the amount of tickets needed. Therefore C is right.
The answer is C= 74x +35y
You should have the appropriate variable with the appropriate price, so the x for adult tickets goes with the prices for adult tickets and y for number of youth tickets to go with youth prices.
Since these numbers are separate and different, you don't want to combine them like A and B do.

Please look at the attached image to answer the question.
Answer for 1st set:
m∠1=105° and m∠2=75°
Breakdown:
You're given one angle of 75°. That one angle is equal to m∠2. Since m∠2 is making a linear pair with m∠1, you take 180° (Straight line) and take 75° from it.
180-75=105
Answer for 2nd set:
m∠1=130° and m∠2=50°
Breakdown:
Using the same logic as before, linear pair, blah-blah-blah, you're given 130.
180-130=50
Answer:
m∠1=105° and m∠2=75°
