Write your question here (Keep it simple and clear to get the best answer)4x³-5x is it odd or even function
Answer:
odd
Step-by-step explanation:
To determine if odd/ even
• If f(x) = f(- x) then it is even
• If f(- x) = - f(x) then it is odd
Given
f(x) = 4x³ - 5x , then
f(- x) = 4(- x)³ - 5(- x) = - 4x³ + 5x
Since f(x) ≠ f(- x) then it is not even
- f(x) = - (4x³ - 5x) = - 4x³ + 5x
Since f(- x) = - f(x) , then 4x³ - 5x is odd

Swim team members can race or dive. At a meet, 18 members race. The ratio of racers to divers is 6 : 2. How many members are on the team? Show your work.
Answer:
24
Step-by-step explanation:
Given that:
Total number of members who race = 18
Ratio of racers to divers = 6 : 2
To find:
Total number of members of the team = ?
Solution:
Given the ratio = 6 : 2
As per the ratio given, we can let the number of racers = [tex]6x[/tex]
and
As per the ratio given, we can let the number of divers = [tex]2x[/tex]
As the swim team members can either race or dive, we can say that:
Total number of members on the team = Number of racers + Number of divers
Total number of members on the team = [tex]6x+2x=8x[/tex]
As per the question statement, we are given that:
[tex]6x=18\\\Rightarrow x =\dfrac{18}{6}\\\Rightarrow x =3[/tex]
Therefore, total number of team members = 8 [tex]\times[/tex] 3 = 24

Vincent wants to have balloons delivered to
a friend. He can choose between two
stores.
• Store) charges $70.00 for delivery,
plus $2.50 per balloon delivered.
• Store K charges $60.00 for delivery.
plus $5.00 per balloon delivered.
The equations below represent the charges
at the two stores, where represents the
total charge for delivering balloons.
Answer: store 1 f(X)= 70+2.50X Store 2 f(x) 60+5x
Step-by-step explanation: So i gave you the equations because i don't really understand the what its asking me for and the lower price is store 1
The equations that represents the two stores are as follows;
f(x) = 70 + 2.50x
g(x) = 60 + 5x
How to form linear equations?The situation can be modelled to a linear equation.
Therefore,
y = mx + b
where
m = slopeb = y-interceptTherefore,
First stores equation:
f(x) = 70 + 2.50x
where
x = number of ballon delivered.
Second stores equation:
g(x) = 60 + 5x
where
x = number of ballon delivered

9 x 10^2 is ? times as much as 3 x 10^-2.
A. 6 x 10^0
B. 3 x 10^-4
C. 6 x 10^4
D. 3 x 10^4
Answer: 3 × 10^4
Step-by-step explanation:
9x10^2 is how many times as much as 3x10^-2?
9 × 10^2 = 9 × 100 = 900
3 × 10^-2 = 3 × 0.01 = 0.03
We then divide, this will be:
= 900/0.03
= 30000
This can be represented as:
30000 = 3 × 10^4
It can be clearly seen that 9 x 10^2 is is 3 x 10^4 times of the number 3 x 10^-2.
What is multiplication?Multiplication is one of the basic mathematical operations. When a number is multiplied by another, the it is a given number of times that number.
As such, we can we that 9 x 10^2 is is 3 x 10^4 times of the number 3 x 10^-2.

On average, a refrigerator door is opened 22 times each day. Len has two refrigerators in his house. Based on this average, about how many times in a 9−week period are the refrigerator doors opened?
Answer:
2772 times
Step-by-step explanation:
On average, a refrigerator door is opened 22 times each day.
Len has two refrigerators in his house.
Step 1
From the above question:
1 refrigerator = 22 times
2 refrigerators = 2 × 22 times
= 44 times.
Hence, Per days 2 refrigerators is opened 44 times
Step 2
In 1 week = 7 days =(For 2 refrigerators)
1 day = 44 times
7 days = x times
x = 7 × 44
x = 308 times.
Hence in 1 week, the 2 refrigerators are opened 308 times
Step 3
How many times in a 9−week period are the refrigerator doors opened
1 week period = 308 times
9 week period =
308 times × 9
= 2772 times
Write a sine function that has a midline of 3, an amplitude of 4 and a period of 2π.
PLEASE HELP! WILL MARK BRAINLIEST!
Answer:
y = Asin(Bx-C) + D
D is midline. A is amplitude. Period is 2π/|B| (More useful for graphing and shows the effect of B). Strictly speaking, the frequency is the inverse of period: f = |B|/(2π), but a lot of math texts say frequency when they mean angular frequency which is rad/s vs. cycles/sec. The angular frequency ω = 2πf (2π rads/cycle) or just |B|. Finally the function is translated to the right C/B (to the left if C/B is negative)
Step-by-step explanation:
The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be y = 4 sin(2πx) + 3.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The sinusoidal function is given as,
y = A sin(2πx + ∅) + k
Where 'A' represents the amplitude, '∅' represents the phase difference, '2πx' represents the time period, and 'k' represents the midline.
The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be given as,
y = 4 sin(2πx) + 3
The sine function has a midline of 3, an amplitude of 4, and a period of 2π will be y = 4 sin(2πx) + 3.
