Answer: It's either 278 or 178
Step-by-step explanation: I didn't know what equation the question wants you to use so for the first equation it showed I did (10^2+24+10+144) and got 278. For the second equation I did 24+10+144 and got 178. Considering it gave you ax+b as an area equation I just added them (same with the other equation). I don't know whether those are correct of not though.

At a baseball game, 3 drinks and 4 hotdogs cost $15.00. At the same game, 3 drinks and 1 hotdog cost $10.50. Find the cost for a drink.
Answers
Answer:
$3
Step-by-step explanation:
Given data
Let the cost of drinks be x
and the cost of hotdogs be y
so
3x+4y=15-------1
also
3x+y= 10.5------2
solve 1 and 2
3x+4y=15
-3x+y= 10.5
3y= 4.5
divide both sides by 3
y= 4.5/3
y= $1.5
Put y= 1.5 in 1
3x+4(1.5)=15
3x+6= 15
3x=15-6
3x= 9
x= 9/3
x= $3
Hence the cost of a drink is $3

What is the area of the shaded sector?
A. 41π units^2
B. 8π units^2
C. 16π units^2
D. 20π units^2
Answers
The area of the shaded sector of the circle is 16π units².
How to find the area of a circle?Suppose the circle has radius of 'r' units, then, its area is given as:
[tex]A = \pi \times r^2[/tex]
sq. units
Since radius of a circle is half of its diameter, so if diameter is of 'd' length, then r= d/2, thus, area can be rewritten as:
[tex]\pi \times (\dfrac{d}{2})^2[/tex]
sq. units
We are given that;
θ = r radians
r = 4 units
Now,
To convert radians to degrees, we use the formula:
Degrees = Radians × 180°/π
So,
θ = r × 180°/π
Substituting these values in the formula for area of a sector, we get:
Area of a sector = (r × 180°/π / 360°) × π(4)²
Simplifying, we get:
Area of a sector = r² units²
=16π units².
Therefore, by the area of a circle the answer will be 16π units².

f(-2) = 28
Step-by-step explanation:
Given that,

We need to find the value of f(-2). Put x = -2 in the given function. SO,
[tex]f(-2) = - 3(-2)^3 -(-2)^2 +8\\\\=24-4+8\\\\=28[/tex]

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!!
Answers
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
