Answer:
24
Step-by-step explanation:
A negative integer times a negative integer is the same as a positive integer times a positive integer, so this would be the same as (8)(3) which is 24.
In a video game, two characters follow paths represented by r = StartRoot 3 EndRoot + 2 cosine (theta) and r = 4 cos(θ), respectively. The characters travel at different speeds and could collide with each other. Which values of θ correspond to possible collision points? Check all that apply.
The point of collision is θ = π/6.
What are polar equations?A curve's polar equation is often stated with r as a function of θ and represented in polar coordinates.
The given equations are r = √3 + 2cosθ and r = 4cosθ.
The characters will collide at the intersection of these paths, the intersection of the two equations is given by:
√3 + 2cosθ = 4cosθ
4cosθ - 2cosθ = √3
2cosθ = √3
cosθ = √3/2
θ = cos⁻¹(√3/2)
θ = π/6
Hence, the point of collision is θ = π/6.

What is the difference between: |x+3| = 10 & |x| + 3 = 10
Answer:
Step-by-step explanation:
|x+3| = 10 means the absolute value of x+3 equal 10, so the answer to that means x= -13 or x= 7 (i.e. |-13+3| = |-10| =10, |7+3| = |10| = 10)
|x| + 3 = 10 means the absolute value of just x, so the answer to that would be x= -7 or x= 7 (i.e. |-7|+3 = 7+3 = 10, |7|+3 = 7+3 = 10)
However, take everything I say with a grain of salt, because I struggle some with Absolute Value Equations as well.
I hope this helps give you an idea of what you're looking at, though :)

Samuel invested $53,000 in an account paying an interest rate of 6.7% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be in the account after 17 years?
Answer:
A≈165553.09
Step-by-step explanation:
To the nearest cent, there would be $174,529.50 in Samuel's account after 17 years of continuous compounding at an interest rate of 6.7%.
What is continuous compounding?The formula for calculating the amount of money in an account with continuous compounding is:
[tex]A = Pe^{(rt)}[/tex]
where:
A = the amount of money in the account after t years
P = the principal amount invested
r = the annual interest rate (as a decimal)
t = the time in years
e = Euler's number (approximately 2.71828)
Using this formula, we can calculate the amount of money in Samuel's account after 17 years as follows:
[tex]A = 53,000 \times e^{(0.067\times 17)[/tex]
A ≈ $174,529.50
Therefore, to the nearest cent, there would be $174,529.50 in Samuel's account after 17 years of continuous compounding at an interest rate of 6.7%.

Answer:
B, the parabola is narrower.
Step-by-step explanation:
Given the parent square function: x^2.
A vertical stretch by a scale factor of 3 is made to transform x^2 into 3x^2.
A stretch makes the function narrower, a compression makes the function wider.
Therefore the parabola is narrower.
The perimeter of a fence must be no larger than 500 feet in length. The longer side of the fence must be 10 feet more than twice the length of the shorter side. Write and solve and inequality to determine the maximum length of the shorter side of the fence.
Answer:
The shortest side of the fence can have a maximum length of 80 feet
Step-by-step explanation:
Inequalities
To solve the problem, we use the following variables:
x=length of the longer side
y=length of the sorter side
The perimeter of a rectangle is calculated as:
P = 2x + 2y
The perimeter of the fence must be no larger than 500 feet. This condition can be written as:
[tex]2x + 2y \le 500[/tex]
The second condition states the longer side of the fence must be 10 feet more than twice the length of the shorter side.
This can be expressed as:
x = 10 + 2y
Substituting into the inequality:
[tex]2(10 + 2y) + 2y \le 500[/tex]
This is the inequality needed to determine the maximum length of the shorter side of the fence.
Operating:
[tex]20 + 4y + 2y \le 500[/tex]
Simplifying:
[tex]20 + 6y \le 500[/tex]
Subtracting 20:
[tex]6y \le 500 - 20[/tex]
[tex]6y \le 480[/tex]
Solving:
[tex]y \le 480 / 6[/tex]
[tex]y \le 80[/tex]
The shortest side of the fence can have a maximum length of 80 feet
a bag contains 5 red balls and some Blue Balls if the probability of drawing a blue ball is double that of red ball find the number of a blue balls in the back
Answer:
10
Step-by-step explanation:
Let the number of blue balls be x.
Number of red balls = 5
Total number of balls = x + 5
P (getting a red ball) = 5/x+5
P (getting a blue ball) = x/x+5
Given that
2(5/x+5) = x/x+5
10(x+5) = x^(2) +5x
x^(2)-5x-50=0
x(x-10)(x+5)
Now either x-10 = 0 or x+5= 0
But number of balls cannot be negative.
Hence, the number of blue balls is 10.

What conjecture can you make about the sum of the first 33 positive odd numbers?
Answer:
The number series 1, 3, 5, 7, 9, . . . . , 59. Therefore, 900 is the sum of first 30 odd numbers.
The conjecture we can make is C. The sum is equal to the no. of terms squared.
According to the given question we have been asked What conjecture can you make about the sum of the first 33 positive odd natural numbers.
We know that the sum of first 'n' odd natural numbers is n².
So, the sum of first 33 odd natural numbers is (33)² which is = 1089.
Let us prove this by AP.
First term(a₁) is = 1.
common difference(d) = 2.
No. of terms (n) = 33.
∴ aₙ = a₁ + (n-1)d
aₙ = 1 + (33-1)2
aₙ = 1 + 32(2).
aₙ = 1 + 64.
aₙ = 65.
∴ S₃₃ = 33/2×[ 2(1) + (33-1)2].
S₃₃ = 33/2×[ 2 + 64].
S₃₃ = 33/2×66.
S₃₃ = 33×33.
S₃₃ = 1089.

What is the largest multiple of 7?
Answer:

Step-by-step explanation:
In a trivia contest, players form teams and work together to earn as many points as possible for their team. Each team can have between 3 and 5 players. Each player can score up to 10 points in each round of the game. Elena and four of her friends decided to form a team and play a round.
Write an expression, an equation, or an inequality for each quantity described here. If you use a variable, specify what it represents.
1. the number of points that Elena's team earns in one round
2. the number of points Elena's team earns if each player misses one point
3. the number of players in a game if there are at least 3 teams
Answer:
(i) From 0 to 50.
(ii) From 3 to 5.
(iii) From 3R to 5R, where R=3,4,5,...
Step-by-step explanation:
Let N be the number of players in a team.
As each team can have numbers of player ranging from 3 to 5, so
[tex]3\leqN\leq5\cdots(i)[/tex]
Let P be the points scored by one player in one round of the game.
As each player can score up to 10 points in each round of the game, so
[tex]0\leq P \leq 10\cdots(ii)[/tex]
(1) There are 5 members in the team formed by Elena.
So, points earned by 5 players in 1 round = 5P
From equation (ii), the range is
[tex]0\leq 5P \leq 50[/tex]
Hence, the points earned by Elena's team is ranging from 0 to 50.
(2) If each played misses 1 point, then,
Points earned by 1 player in 1 round = 10-1=9
Hence, points earned by 5 players in 1 round = 9x5=45.
(3) Let R (an integer) denoted the number of teams.
As there are at least 3 teams in the game, so
[tex]R\geq3\cdots(iii)[/tex]
As the number of players in one team is N, so
the number of players in R team is NR, where R=3,4,5,...
Now, from equation (i)
[tex]3R\leqNR\leq5R[/tex]
Hence, if there are at least 3 teams, then the number of players is ranging from 3R to 5R.
For R=3, the number of players in the game is ranging from 3x3=9 to 5x3=15.
Which graph represents this equation?
y = 1/2x^2 + 2x - 6
Answer:
C
Step-by-step explanation:
y = 1/2x^2 + 2x - 6
When, x = 0, y = - 6
you don't need to find another variable. Because in number C u can find a graph that has y= -6 when x =0.
The graph of the given equation is the graph C
What is a graph?In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
Given is an equation, y = x²/2+2x-6, we need to identify the graph for the same,
y = x²/2+2x-6
Put x = 0,
y = -6
Point = (0, -6)
Put x = 2,
y = 2+4-6
y = 0
Point = (2, 0)
Put x = -6
y = 18-12-6
y = 0
Point = (-6, 0)
If we see all these points are lying in graph C, which means the graph C is satisfying the condition of the given equation,
Hence, the graph of the given equation is the graph C
