The number of trout in America since 2000 is given by the following formula:
[tex]y=x^2+3x+2[/tex]
"x" is the number of years and "y" is the number of trout in the millions.
Based on this formula, estimate the number of trout in the years 2005, 2010, and 2015.
Describe the trend in the number of trout as the years increase.
Answer:
See below
Step-by-step explanation:
Given formula
y = x² + 3x + 2x- is the number of years after 2000,y - is the number of troutYear 2005, finding number of trout
x = (2005 - 2000) = 5y = 5² + 3*5 + 2 = 42 millionsYear 2010, finding number of trout
x = (2010 - 2000) = 10y = 10² + 3*10 + 2 = 132 millionsYear 2015, finding number of trout
x = (2015 - 2000) = 15y = 15² + 3*15 + 2 = 272 millionsNumber of trout is trending up with significant increase over yeas
Answer:
42 million132 million272 millionThe number of trout inceases a lot each 5 years that pass.Step-by-step explanation:
Number of trout in 2005.
Find the number of years apart from 2000 to 2005.
2005 - 2000 = 5
Substitute for x and solve for y.
y = x² + 3x + 2
y = (5)² + 3(5) + 2
y = 25 + 15 + 2
y = 40 + 2
y = 42 million
Number of trout in 2010.
Find the number of years apart from 2000 to 2010.
2010 - 2000 = 10
Substitute for x and solve for y.
y = x² + 3x + 2
y = (10)² + 3(10) + 2
y = 100 + 30 + 2
y = 130 + 2
y = 132 million
Number if trout in 2015.
Find the number of years apart from 2000 to 2015.
2015 - 2000 = 15
Substitute for x and solve for y.
y = x² + 3x + 2
y = (15)² + 3(15) + 2
y = 225 + 45 + 2
y = 270 + 2
y = 272 million

Step-by-step explanation:
You are certain to get 2 Kings when selecting 50 cards from a shuffled deck. express the indicated degree of likelihood as a probability value between zero and one inclusive
Answer:
1
Step-by-step explanation:
The probability of this happening would be a 1 when placing a value between zero and one inclusive. One in this case would indicate a 100% probability. This is the case because in the question it is stated that it is "certain" that you will get 2 kings when selecting 50 cards, this means that no matter what it will happen every time 50 cards are drawn, thus making the probability 100%. If the question were phrased differently such as "what is the probability of getting 2 kings from 50 cards drawn?" then the probability would be 0.04 or 4% which is 2/50.
Using probability concepts, it is found that the likelihood is of 1.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
A few observations regarding probabilities are important.
It assumes values between 0% and 100% as percentages and between 0 and 1 as decimals.If an event is certain not to happen, the probability is of 0% = 0.If an event is certain to happen, the probability is of 100% = 1.In this problem, you are certain to get 2 Kings when selecting 50 cards from a shuffled deck, hence the likelihood is of 1.

The sales in thousands of dollars that Terrific Toys makes during one month can be approximated by the functions S(x)=2x³-2x²+4x, where x represents the number of days after the first day of the month. About how many days will it take the store to make $50,000?
Answer:
The days will it take the store to make $50,000 in a whole number are:
30 days.Step-by-step explanation:
Remember that x represents the number of days, so, you must replace different values in the formula until you obtain a value of $50,000, in this form:
S(x)= 2x³-2x²+4xS(1)= 2*1³-2*1²+4*1S(1)= 4 ($4).So, I'll show you that the value that you need is 30 in a whole number.
S(30)= 2*30³-2*30²+4*30S(30)= 52,320 ($52,320)I know that the value exceeds the amount of $50,000, but if you use just a day before:
S(29)= 2*29³-2*29²+4*29S(29)= 47,212 ($47,212)How you can see, if you use 29 days, the value doesn't reach $50,000, by this reason, you must use 30 days to reach it.
Use the formula p=le^kt. A bacterial culture has an initial population of 500. If its population grows to 7000 in 2 hours, what will it be at the end of 4 hours
Answer:
98,000 bacteria.
Step-by-step explanation:
We are given the formula:
[tex]P=le^{kt}[/tex]
Where l is the initial population, k is the rate of growth, and t is the time ( in hours).
We know that it has an initial population of 500. So, l is 500.
We also know that the population grows to 7000 after 2 hours.
And we want to find the population after 4 hours.
First, since we know that the population grows to 7000 after 2 hours, let's substitute 2 for t and 7000 for P. Let's also substitute 500 for l. This yields:
[tex]7000=500e^{2k}[/tex]
Divide both sides by 500:
[tex]e^{2k}=14[/tex]
We can solve for the rate k here, but this is not necessary. In fact, when can find our solution with just this.
Let's go back to our original equation. We want to find the population after 4 hours. So, substitute 4 for t:
[tex]P=500e^{4k}[/tex]
We want to find the total population, P. Notice that we can rewrite our exponent as:
[tex]P=500(e^{2k})^2[/tex]
This is the exact same thing we acquired earlier. So, we know that the expression within the parentheses is 14. Substitute:
[tex]P=500(14)^2[/tex]
Square and multiply:
[tex]P=500(196)=98000[/tex]
So, after 4 hours, there will be 98,000 bacteria.
And we're done!

Find the midpoint of the segment with the endpoints: (-2, 6) and (-3, 7)
Answer:
The midpoint is ( -2.5, 6.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2
(-2+-3)/2 = -5/2 = -2.5
To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2
(6+7)/2 = 13/2 = 6.5
The midpoint is ( -2.5, 6.5)

Blair expects an increase of 3% in her current annual
salary of $42,000. What would her new annual salary
be?
Answer:
$43,260
Step-by-step explanation:
You have the 3% annual income, which you can convert to a decimal. This gives:
42000 * 1.03
42000 represents Blair's initial income, and 0.03 represents the 3% increase.
I chose 1.03 because I don't have to subtract 97% and add it to 42000.

The third term of an A.P is 4m - 2n. If the ninth term of the progression is 2m - 8n. Find the common difference in terms of m and n
Let [tex]a_n[/tex] denote the n-th term in the progression. So
[tex]a_n=a_{n-1}+d[/tex]
for some constant difference between terms d.
Solve for [tex]a_n[/tex] explicitly:
[tex]a_4=a_3+d[/tex]
[tex]a_5=a_4+d=a_3+2d[/tex]
[tex]a_6=a_5+d=a_3+3d[/tex]
and so on, up to
[tex]a_n=a_3+(n-3)d[/tex]
We're told that the third term is [tex]a_3=4m-2n[/tex], and the ninth term is [tex]a_9=2m-8n[/tex], and according to the recursive rule above, we have
[tex]a_9=a_3+6d[/tex]
Solve for d :
[tex]2m-8n=(4m-2n)+6d[/tex]
[tex]-2m-6n=6d[/tex]
[tex]d=-\dfrac{2m+6n}6=\boxed{-\dfrac{m+3n}3}[/tex]

n(t) = 3.53t^2 - 33.04t + 117.56
Which graph would most likely be associated with the given model?
Regression equations can be linear, quadratic or exponential
The graph that would most likely be associated with the given model is (b)
The regression equation is given as:
[tex]n(t) = 3.53t^2 - 33.04t + 117.56[/tex]
The above regression equation is a quadratic function (and non-linear).
So, the graph must represent a non-linear relationship.
From the given graphs, only graph (b) represents a quadratic function.
Other options are either linear models or exponential.
Hence, the graph that would most likely be associated with the given model is (b)

Don't worry, don't worry child. Oh, geometry. How lucky are you: finally knowing this treasury of humanity. I'm jealous now. Haha.
In the annex, you can see what is happening :)
Look that, if a and b are paralels, 4x + 28 is External Alternate of the Opposite Vertex of 116, which is also 116. Then, they have the same value: 4x + 28 = 116.
If you don't remember those concepts, review the initial part of geometry. The proof of that is quite simply, moreover is easy to mentally deduce that.
