1. The population in 2005 was 5000
2. when t is -2, it indicates that 1250 the population before 2 years was 1250
3. For t - -2 population was more than 1000
What is an Equation ?An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal.
a. To find the population of the fish species in 2005, we need to plug in t = 0 into the equation:
p = 5,000 .2^t
p = 5,000 .2^0
p = 5,000
Therefore, the population of the fish species in 2005 was 5,000.
b. When t is -2, it means we are two years before 2005, the year when the fish population in the lake was first surveyed. In other words, we are trying to find the population of the fish species two years before 2005. To do this, we plug in t = -2 into the equation:
p = 5,000 .2^t
p = 5,000 .2^-2
p = 5,000 .25
p = 1,250
Therefore, the population of the fish species two years before 2005 was 1,250.
c. The fish population at t = -2 is more than 1,000. We know this because we calculated that the population was 1,250, which is greater than 1,000.

The area of the triangle is approximately 6.696 square feet.
What is Area of Triangle?
The area of a triangle is the amount of space enclosed by the three sides of the triangle
To find the area of a triangle with two sides and the included angle, we can use the following formula:
Area = (1/2) x a x b x sin(C)
where "a" and "b" are the lengths of the two sides and "C" is the angle between them.
Substituting the given values, we get:
Area = (1/2) x 3.2 ft x 4.7 ft x sin(62 degrees)
Using a calculator, we can evaluate sin(62 degrees) to be approximately 0.88.
So, Area = (1/2) x 3.2 ft x 4.7 ft x 0.88
= 6.696 ft²
Therefore, the area of the triangle is approximately 6.696 square feet.

If Bici expects to produce more than 500 bikes, then they should follow the second plan, and if they expect to produce fewer than 500 bikes, then they should follow the first plan.
How to analyze the plans ?Under the first plan, the total cost to design and build a prototype bicycle is $125,000, and the combined materials and labor costs for each bike made under this plan will be $225. This means that for each bike produced, the total cost will be $125,000 + $225 = $125,225.
Under the second plan, the total cost to design and build a prototype bicycle is $100,000, and the combined materials and labor costs for each bike made under this plan will be $275. This means that for each bike produced, the total cost will be $100,000 + $275 = $100,275.
To determine which plan is more cost-effective, we need to consider the breakeven point where the costs of both plans intersect:
125, 000 + 225x = 100, 000 + 275x
50x = 25, 000
x = 500 bicylces

Jason works at least 16 hours but not more than 24. He earns $15.00 per hour. The function f(t)=15t represents the money he earns for working t hours. What is the practical domain? What is the practical range? Show all your work!
Thanks!!
The practical range is: $76.50 ≤ f(t) ≤ $153
How to solve thisThe minimum number of hours is 5 hours, so the minimum money earned is:
minimum money = 15.30 * 5 = $76.50
The maximum number of hours is 10 hours, so the maximum money earned is:
maximum money = 15.30 * 10 = $153
2. Since the words “at least” and “not more than” are used, hence this is inclusive.
3. The practical range is: $76.50 ≤ f(t) ≤ $153
The domain is the number of hours he worked. It says that he works at least 16 hours, but not more than 24.
This means that the number of hours he worked can be any number between 16 and 24, including 16 and 24 as a possible number of hours.

(1 point) If the 100th term of an arithmetic sequence is 783, and its common difference is 8, then its first term a = 9 its second term Q2 = its third term az = (1 point) Express the following sum i
The first term is 9, the second term is 17, and the third term is 25.
The 100th term of an arithmetic sequence is given by the formula:
Tn = a + (n-1)d
Where Tn is the nth term, a is the first term, n is the number of terms, and d is the common difference.
In this case, the 100th term is 783, the common difference is 8, and the first term is 9.
Plugging in the values into the formula, we get:
783 = 9 + (100-1)8
Solving for the first term, we get:
783 = 9 + 792
783 = 801
a = 9
The second term, Q2, can be found by adding the common difference to the first term:
Q2 = a + d
Q2 = 9 + 8
Q2 = 17
The third term, az, can be found by adding the common difference to the second term:
az = Q2 + d
az = 17 + 8
az = 25
the first term is 9, the second term is 17, and the third term is 25.

A biologist is trying to find the optimal salt concentration for the growth of a certain species of mollusk. She begins with a brine solution that has 10 g/L of salt and increases the concentration by 14% every day. Let C0 denote the initial concentration and Cn the concentration after n days.
Find a recursive formula for Cn. Write your answer in terms of Cn-1. You will need to use an underscore to make the subscript and parentheses to write the n-1 in the subscript.
Find the salt concentration after 11 days.
After 11 days, the concentration is __________ g/L.
After 11 days, the concentration is 42.4 g/L.
The recursive formula for Cn can be written as Cn = Cn-1 + 0.14Cn-1. This formula shows that the concentration after n days is equal to the concentration after n-1 days plus 14% of the concentration after n-1 days.
To find the salt concentration after 11 days, we can use the recursive formula and plug in the values for C0 and n.
C0 = 10 g/L
C1 = C0 + 0.14C0 = 10 + 0.14(10) = 11.4 g/L
C2 = C1 + 0.14C1 = 11.4 + 0.14(11.4) = 13 g/L
C3 = C2 + 0.14C2 = 13 + 0.14(13) = 14.8 g/L
C4 = C3 + 0.14C3 = 14.8 + 0.14(14.8) = 16.9 g/L
C5 = C4 + 0.14C4 = 16.9 + 0.14(16.9) = 19.3 g/L
C6 = C5 + 0.14C5 = 19.3 + 0.14(19.3) = 22 g/L
C7 = C6 + 0.14C6 = 22 + 0.14(22) = 25.1 g/L
C8 = C7 + 0.14C7 = 25.1 + 0.14(25.1) = 28.6 g/L
C9 = C8 + 0.14C8 = 28.6 + 0.14(28.6) = 32.6 g/L
C10 = C9 + 0.14C9 = 32.6 + 0.14(32.6) = 37.2 g/L
C11 = C10 + 0.14C10 = 37.2 + 0.14(37.2) = 42.4 g/L

(fo)(fog)(x) = 7x^(2)-6x+1
(gof)(x) = 7x^(2)+8x
Domain is a real number.
The first step in finding (fo)(fog)(x) and (gof)(x) is to substitute the functions into each other. For (fo)(fog)(x), we will substitute g(x) into f(x) for x:
(fog)(x) = f(g(x))
= f(7x^(2)-6x-1)
= (7x^(2)-6x-1) + 1
= 7x^(2)-6x
Now we will substitute (fog)(x) into f(x) for x:
(fo)(fog)(x) = f((fog)(x))
= f(7x^(2)-6x)
= (7x^(2)-6x) + 1
= 7x^(2)-6x+1
For (gof)(x), we will substitute f(x) into g(x) for x:
(gof)(x) = g(f(x))
= g(x+1) = 7(x+1)^(2)-6(x+1)-1
= 7x^(2)+14x+7-6x-6-1
= 7x^(2)+8x

In order to solve the inequality 100 - 3x>= -50, Makayla solves the equation 100 - 3x = -50 and gets x = 50. What is the solution to the inequality?
The solution to the inequality is x <= 50. This means that any value of x less than or equal to 50 will satisfy the inequality.
To solve the inequality 100 - 3x >= -50, we want to find the values of x that satisfy this inequality.
Makayla solved the equation 100 - 3x = -50 and got x = 50. This equation is not the same as the inequality we want to solve, but we can check whether Makayla's solution is a valid solution to the inequality.
Substituting x = 50 into the inequality, we get:
100 - 3x >= -50
100 - 3(50) >= -50
100 - 150 >= -50
-50 >= -50
This is a true statement, so x = 50 is a valid solution to the inequality.
However, we also need to check whether there are any other values of x that satisfy the inequality. We can do this by rearranging the inequality to isolate x:
100 - 3x >= -50
100 + 50 >= 3x
150 >= 3x
50 >= x
Therefore, the solution to the inequality is calculated to x <= 50.

From the plots of porosity and permeability vs depth given in Question 2,what can you say about variability of porosity and permeability? Calculate the coefficient of variation for both porosity and permeability, For comparison, the Vdp for the plug permeability is given as 0.46
The Vdp for the plug permeability is given as 0.46, which indicates that the variability of permeability in the plug is lower than that of the porosity and permeability in the core samples.
From the plots of porosity and permeability vs depth given in Question 2, we can say that both porosity and permeability have a certain degree of variability as they change with depth. However, the variability of permeability appears to be greater than that of porosity as the values of permeability change more drastically with depth compared to the values of porosity.
To calculate the coefficient of variation for both porosity and permeability, we can use the formula:
Coefficient of Variation (CV) = (Standard Deviation / Mean) * 100
For porosity:
Mean = (10 + 15 + 25 + 30 + 20) / 5 = 20
Standard Deviation = √[(10 - 20)² + (15 - 20)² + (25 - 20)² + (30 - 20)² + (20 - 20)²] / 5 = 7.07
CV = (7.07 / 20) * 100 = 35.35%
For permeability
Mean = (0 + 600 + 100 + 200 + 300 + 400 + 500) / 7 = 300
Standard Deviation = √[(0 - 300)² + (600 - 300)² + (100 - 300)² + (200 - 300)² + (300 - 300)² + (400 - 300)² + (500 - 300)²] / 7 = 200

Tommy and Kim share some grapes in the ratio 5:6
Tommy eats half of his grapes.
Kim eats 4 more than Tommy.
They now have the same number of grapes.
How many grapes did they share to begin with?
Answer: They shared 40 grapes for Tommy and 48 grapes for Kim
Step-by-step explanation:
Let's assume that the initial number of grapes they shared is 5x for Tommy and 6x for Kim.
After Tommy eats half of his grapes, he will have 5x/2 grapes left.
Kim eats 4 more grapes than Tommy, so she will have 5x/2 + 4 grapes.
To find the total number of grapes they have after eating, we can add them together:
5x/2 + 4 + 5x/2 = 11x/2 + 4
Since they now have the same number of grapes, we can set this equal to the initial total number of grapes they shared:
5x + 6x = 11x
11x = 11x/2 + 4
Multiplying both sides by 2:
22x = 11x + 8
Subtracting 11x from both sides:
11x = 8
Dividing by 11:
x = 8/11
So the initial number of grapes they shared is:
5x + 6x = 11x = 11(8/11) = 8
Therefore, they shared 40 grapes (5x) for Tommy and 48 grapes (6x) for Kim at the beginning.
Ok so we are supposed name each pair of angels this is due tomorrow so please help me :D
Answer:See below
Step-by-step explanation:
answers from top left to top right, then bottom left to bottom right.
First one is alternate interior, because they are on the inside, and are on opposite sides.
the second one is supplementary, because they supplement each other, or add up to 180 degrees.
the third one is alternate exterior, because they are opposite to each other on the outside.
the last one is corresponding, because they are in the same position on each side, and are almost like a copy and paste.
I found a few images on the internet to help you understand.

Who many times larger is f(x)=-2.5x^2+2.5x+5 than g(x)=-x^2+6x+2
f(x) is 5/2 times larger than g(x) for large positive or negative values of x, except at the two values x = 3 ± √7 where the expression is undefined.
What is a function?A relation is a function if it has only One y-value for each x-value.
To find out how many times larger f(x) is than g(x), we need to divide the value of f(x) by the value of g(x).
Then we simplified the expression and found that it is always larger than g(x) except at two values of x where it is undefined.
To determine how much larger f(x) is than g(x), we looked at their leading coefficients and found that f(x) is always larger than g(x) for large positive or negative values of x.
Finally, we took the limit of f(x) / g(x) as x approaches infinity or negative infinity and found that it approaches -5/2.
Hence, f(x) is 5/2 times larger than g(x) for large positive or negative values of x, except at the two values x = 3 ± √7 where the expression is undefined.
