Answer:
y-intercept is (0, -2) and asymptote of y = -2.5
Step-by-step explanation:
If you substitute 0 in for x and simplify, then you will have the y-intercept
y = [tex]\frac{1}{2} (7)^{0} - 2.5 = \frac{1}{2} (1) - 2.5 = \frac{1}{2} - 2.5 = -2[/tex]
The y-intercept is (0, -2)
If the -2.5 were not there, then the graph would have an asymptote at y = 0 or the x-axis
The -2.5 moves the graph down 2.5 units so that y = -2.5 is the asymptote
Therefore, the first answer is correct

I really really need help with this and no one is answering. I've looked everywhere for how to do this and I fell like its simple but I can't find it. given -2+4i, express the complex number in polar form. I know the answer is 2 root 5(cos2.03 + isin2.03), but I don't know where the 2.03 comes from. Can someone explain please?

Complex number:
The polar form of z is:
Explanation:
z = −2 + 4i
z = 4.4721 · (cos 117o + i · sin 117o)
The polar form of the complex number z = a + bi is:
z = r · (cos θ + i · sin θ)
where, r is the modulus of z and θ is an argument of z. The moduo for a = −2 and b = 4 is:
r = a2 + b2 = · · · = 4.4721 To find argument θ we use one of the following formulas:
b θ=arctan a ifa>0
b o θ=arctan a +180 ifa<0
θ=90o ifa=0andb>0 θ=270o ifa=0andb<0
Inthisexample: a=−2andb=4so:
θ=arctan a +180
θ=arctan 4 +180o −2
b o
θ = arctan (−2) + 180o θ ≈ 117o

[One Step Inequalities]
Answer:
C
Step-by-step explanation:
Who can answer this??
Ths question is not complete but I will try my best to guide you through it so you can answer it. So what the question is asking you to do is that you have to plug in the coordinates into the equation. I don't want to give you an incorrect answer so I will explain it and you can do it yourself with the full question. First use the second equation as it is a full equation with an equal sign. Once plugged in you can find that c and d do not make the second equation true. A and B both complete the second equation. This means that either A or B is the answer. Since the first equation does not have an equal sign meaning it is not complete I can not answer it and I am sorry. But I have cut the answer down for you to A and B. If this answer helped you in the slightest please check out my channel The Game Rater. Thank you and I appreciate it.

The math club is going to sell t-shirts as a fundraiser. They buy 100 t-shirts and pay a total of $600 for the t-shirts and printing costs.
If they sell each t-shirt for $12, how many t-shirts must they sell to make a profit of $300?
O A. 9
OB. 25
O C. 50
OD. 75
O E 100
They have to sell D. 75 shirts to make a profit of $300.
The total cost of buying and printing the shirts was $600.
In order to make a profit of $300, they would therefore have to raise:
= Cost + profit
= 600 + 300
= $900
As they are selling each shirt $12, the number of shirts they would have to sell to get to $900 is:
= 900 / 12
= 75 shirts
They would therefore have to sell 75 shirts in order to make a profit of $300.

Biologists notice an alarming trend in the walleye population in Lake Erie. Despite efforts, the population is decreasing by 15% each year. They estimate the walleye population was 26 million at the beginning of the current year. Write a sequence that lists the population for the first 4 years using 26 million as the first term.
Walleye populations are considered to be in a rehabilitation state when they are between 15 and 20 million. In what year will the population reach this level? In addition to a harvest restriction, what intervention could be used?
Using the formula [tex]s_n = \frac{a^1 - a^1 (1 + r)^n}{1-(1+r)}[/tex] the sum of the population for the first 10 years? Remember it is decreasing by 15% each year!!
Answer:
Part A
The population for the first four years are;
Year 1; 26,000,000,
Year 2; 22,100,000
Year 3; 18,785,000
Year 4; 15,967,250
Part B
i)The third year
ii) Provision of spawning environment and the reduction of predators
Part C
The population after 10 years is approximately 139,208,436
Step-by-step explanation:
Part A
The given parameters are;
The rate at which the population is decreasing = 15%
The population of the walleye at the beginning of the current year, P = 26 million
Therefore, we have;
The population of subsequent year = 0.85 × The population of the current year
Therefore, we have a geometric series, with a first term, a = 26 million, and a common ratio, r = 0.85, given as follows;
aₙ = a + ar + ar² + ...
Therefore the first 4 years using 26 million as the first term are;
a₁ = 26 × 10⁶
a₂ = 26 × 10⁶ × 0.85 = 22,100,000
a₃ = 26 × 10⁶ × 0.85² = 18,785,000
a₄ = 26 × 10⁶ × 0.85³ = 15,967,250
The population for the first four years are;
26,000,000, 22,100,000, 18,785,000, 15,967,250
Part B
i) Given that the walleye population are considered to be in rehabilitation state when they are between 15 and 20 million, we have;
The population in the third year = 18,750,000 < 20,000,000
Therefore, the population enters rehabilitation state in the 3rd year
ii) Other intervention method includes provision of a adequate environment for spawning and the removal of predators
Part C
The formula for the sum of the geometric progression is presented as follows;
[tex]S_n = \dfrac{a^1 - a^1 \cdot (1 + r)^n}{1 - (1 + r)}[/tex]
Therefore, we have;
[tex]S_n = \dfrac{26 - 26 \cdot (1 - 0.15)^{10}}{1 - (1 - 0.15)} = 139.208436581[/tex]
The population after 10 years, Sₙ = 139.208436581 × 10⁶ ≈ 139,208,436

Answer:
x = -1, and y = -2, giving you the answer (-1, -2)
Step-by-step explanation:
In the second equation, we're told that y is equal to 2x. With that, we can replace "y" in the first one with "2x", giving us:
-4x - 2x = 6
-6x = 6
x = -1
Now that we know the value of x, we can simply plug it into the first equation to find y:
-4x - y = 6
-4(-1) - y = 6
4 - y = 6
-4 + y = -6
y = -6 + 4
y = -2
So x = -1, and y = -2
The sum of two numbers is 17 and their difference is 5, what are the two numbers?
Answer:
11, 8
Step-by-step explanation:
x + y = 17
x - y = 5
The "y" cancels out when you add the two equations and you end up with:
2x = 22
x = 11
Then, plug the "x" back into one of the equations to find "y":
11 + y = 17
y = 6
