Plug in maximum value of x (3) and see what you get. The maximum value of the expression when plugged in is C.
[tex]3^3-3\cdot3+5=C[/tex]
[tex]27-9+5=C\implies 23=C[/tex]
Now that means,
[tex]x^3-3x+5\leq 23[/tex] for any x in [tex][0,3][/tex]

Does anyone know how to divide a fourth degree polynomial
Answer: Polynomial long division can be used to divide a polynomial by any polynomial with equal or lower degree. The Division Algorithm tells us that a polynomial dividend can be written as the product of the divisor and the quotient added to the remainder.
Step-by-step explanation:
If a stock valued at $40 per share increases by 20% and then decreases by 25% what is the resulting value of the stock?
Answer:
$36
Step-by-step explanation:
The stock value of $40 increased by 20%.
Increased value
= 20% of $40
= (20/100) × $40
= $800/100
= $8
New stock value
= Initial value + increased value
= $40 + $8
= $48
Then, the value decreased by 25%.
Decreased value
= 25% of $48
= (25/100) × $48
= $1200/100
= $12
New stock value
= Initial value + decreased value
= $48 - $12
= $36
So, the resulting stock value is $36.
Answer:
The resulting value of the stock is $36.
Step-by-step explanation:
First, we need to find out what 20% of $40 is.
40 x 0.20 = 8
40 + 2 = $48
Therefore, the stock value, when increased, is $48.
Now, we need to see what 25% of $48 is.
48 x 0.25 = 12
48 - 12 = $36
Therefore, the resulting value of the stock is $36.

Answer:
A.
Step-by-step explanation:
one x value cant go to two y values
Answer:
No....Not at all
You can select option A as the correct answer
Step-by-step explanation:
There can be two possibilities
x is an independent variable and y is a dependent variabley is an independent variable and x is a dependent variableFrom the definition of Function, We know, the value of a dependent variable corresponds to exactly one value of the independent variable
For possibility 1, For x = 5 and 9, y = 2 & for x = 5 and 7, y = 3
So this can't be a function
For possibility 2, For y = 3 and 2, x = 5
So this can't be a function

7+6(-8x-7)=3(-6x+8)+1
Answer:
x = -2
Step-by-step explanation:
7 - 48x - 42 = - 18x + 24 + 1
-35 - 48x = -18x + 25
-48x +18x = 25 =35
-30x = 60
x = -2
Answer:
-2
Step-by-step explanation:
7+6 (-8x-7)=3 (-6x+8)+1
7-48x-42= -18x+24+1
-48+18= 24+1-7+42
-30x=60 then divide the two sides with -30

How do i solve
a·a²·a³
Answer:
a^6
Step-by-step explanation:
When the same numbers, the power can be just added together
For example
n x n x n =n^3 right?
Ya cuz when they don't put the power, it means to the power of 1
Therefore
a x a^2 x a^3
Just means
a ^ (1+2+3)
=a^6
Answer: a^6
Step-by-step explanation:
Term does not have an exponent so it’s automatically 1. So, a^1xa^2xa^3.
Multiply terms and add their exponents. So, a^1+2+3z
Add all exponents and you get 6. So, a^6

A Shape Question 5 options: 13 yd.² 314 yd.² 251 yd.² 503 yd.²
Answer:
What is question? surface area of upright part of cylinder is approx 314 sq yd. Surface area of entire cylinder is approx 471 sq yd, which isn't a choice.
Step-by-step explanation:
Assuming you're looking for surface area of cylinder (since answers are in sq units), you would need to find the area of the top and bottom circles, and the rectangle made by flattening out the upright part of cylinder.
Area of a circle is πr^2 so area of bottom is 25π and of both circles is 50π which equals approx 157.08 sq yd.
The rectangle formed from the upright part would have a width of 10 yds and a length equal to circumference of the circle. Since C = πd, C is approx 31.4yd. A = l x w so A = 31.4 x 10 or approx 314 sq yd.

g= -2+2a
Answer: a= [tex]g+2 / 2[/tex]
Step-by-step explanation:
g= -2 + 2a
>> -2+2a=g ( side change )
>> -2+2a +2 = g+2 ( adding 2 both side)
>> 2a = g+2
>> 2a /2 = g+2 /2 ( divide by 2 both side)
>> a= g+2 /2

The density d kg/m3 of a cube of mass m kilograms and side length x meters is given by the formula:  What is the value of d if m = 40 and x = 0.2?
Answer:
5000kg/m3
Step-by-step explanation:
Its easy to get the answer of a question from the unit.
So, it will be mass over metre cube.
Therefore, m=40kg x= (0. 2)^3 =0. 008m
40/0. 008 = 5000kg/m^3

In Ted's class, students were asked to name their favorite sport. Football was the response of 1/8 of them. If 3 students said football, how many students are in Ted's class?
24 Students
If 1/8 of the total is 3, then the total is 3 multiplied by 8 = 24
Another way:
1/8= 12.5%
12..5%_____3
100%_____x
Cross multiplication
12.5x =3x100(300)
X=24
12.5% of 24 = 3
There are 24 students in Ted's class.
Given that;
In Ted's class, students were asked to name their favourite sport.
And, Football was the response of 1/8 of them.
Let's assume the total number of students in the class is represented by "x".
According to the information given, 1/8 of the class said football, which means (1/8) × x students named football.
We also know that 3 students said football.
So, we can set up the equation:
(1/8) × x = 3
To solve for x, we can multiply both sides of the equation by 8:
x = 3 × 8
x = 24
Therefore, there are 24 students in Ted's class.

A pool charges $7 for 2 daily pool passes.
Which table could represent the situation?
Answer:
Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership.
Option B is the table which could represent the given situation.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
According to the question
A pool charges $7 for 2 daily pool passes.
Using the linear equation y = mx + b
Substitute x = 2, y = 7
[tex]7 = 2m + b[/tex].....(1)
Substitute x = 4, y = 14
[tex]14 = 4m + b[/tex] .....(2)
Using elimination method
Subtract equation 1 from 2
[tex]14 - 7 = 4m - 2m + b - b[/tex]
[tex]7 = 2m[/tex]
[tex]m=\frac{7}{2}[/tex]
Substitute m = [tex]\frac{7}{2}[/tex] in equation 1
[tex]7=2(\frac{7}{2} )+b[/tex]
b = 7 - 7
b = 0
Substitute b = 0 in equation 1
7 = 2m
Similarly
14 = 4m
21 = 6m
28 = 8m
Hence, Option B is the table which could represent the given situation.
