The interval that function f(x)=x³-9x has a positive average rate of change is [ -4, -1 ].
Option D) is the correct answer.
Over which interval does f have a positive rate of change?To determine whether the average rate of change is positive, f(max) - f(min) must be greater than zero.
Given the function; f(x) = x³ - 9x
We determine f(max) - f(min)
At interval [ -2, 1 ]
(x³ - 9x) - ( x³ - 9x )
( (1)³ - 9(1) ) - ((-2)³ - 9(-2))= -8 - 10 = -18 NOT POSITIVE
At interval [ -2, 3 ]
(x³ - 9x) - ( x³ - 9x )
( (3)³ - 9(3) ) - ((-3)³ - 9(-3))= 0 - 0 = 0 NOT POSITIVE
At interval [ -1, 2 ]
(x³ - 9x) - ( x³ - 9x )
( (2)³ - 9(2) ) - ((-1)³ - 9(-1))= -10 - 8 = -18 NOT POSITIVE
At interval [ -4, -1 ]
(x³ - 9x) - ( x³ - 9x )
( (-1)³ - 9(-1) ) - ((-4)³ - 9(-4))= 8 - (-28) = 36 POSITIVE
Therefore, the interval that function f(x)=x³-9x has a positive average rate of change is [ -4, -1 ].

a rectangular fish tank is 50 cm long, 40 cm wide, and 30 cm high.
a) how many cubic centimeters of water will the tank hold?
b) how many milliliters of water will the tank hold?
c) how many liters of water will the tank hold?
Answer:
a) 60,000 cubic cm; b) 60,000 mL; c) 60 L
Step-by-step explanation:
a) V = l x w x h
V = 50 cm x 40 cm x 30 cm = 60,000 cubic cm
b) 1 cubic cm = 1 mL, therefore 60,000 cubic cm = 60,000 mL
c) 1000 mL = 1 L; 60,000 mL = 60 L
x+6y=28, solve for y
Answer:
[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]
Step-by-step explanation:
So when you're solving for y you want to get y by it self meaning there should be nothing with y, including any coefficients. The first step is to usually move any terms to the other side and then divide by the coefficient of y so y "technically doesn't" have a coefficient, while it does, but that coefficient 1, so it doesn't really mean much.
Subtract x from both sides
[tex]6y = -x+28[/tex]
Divide both sides by 6
[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]
The given equation solved for y as y = (28 - x)/6.
The given equation is x+6y=28.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solved for y as follows
Here, x+6y=28
⇒ 6y = 28 - x
⇒ y = (28 - x)/6
Therefore, the given equation solved for y as y = (28 - x)/6.

Will is 30% taller than Wanda, so Will's height is ____% of Wanda's height.
Will's height is % of Wanda's height.
Thus we can conclude that if Will is 34% higher than Wanda, then Will's height is 134% (100% + 34%) of Wanda's height.
Will is 34% taller than Wanda, so Will's height is 134% of Wanda's height.
If Will is 34% of Wanda's height, we can conclude that he has all of Wanda's height plus 34% of that height.
All the height of Wanda represents 100% as it is referring to a complete system.
What is the height?
Height is a way to measure someone or something from base to top or head to toe.
From this, we can conclude that Will is 100% more than 34% of Wanda's height.

Which equation represents a circle that contains the point (-2, 8) and has a center at (4, 0)?
Distance formula: √(x₂-x₁)² + (V2 - V₁)²
O(x-4)² + y² = 100
O(x-4)2 + y² = 10
O x² + (y-4)² = 10
O x² + (y-4)² = 100
Answer:
(x-4)² + y² = 100
Step-by-step explanation:
The only circles that have a center at (4 , 0) are :
(x-4)² + y² = 100
(x-4)² + y² = 10
……………………
• (-2 - 4)² + 8² = (-6)² + 64 = 36 + 64 = 100 ≠ 10
Then
The circle (x-4)² + y² = 10 doesn’t contain the point (-2, 8)
• (-2 - 4)² + 8² = 100
Then
The circle (x-4)² + y² = 100 contains the point (-2, 8)

A bank loaned out $11,000, part of it at the rate of 8% per year and the rest at 18% per year. If the interest received in one year totaled $1500, how much was loaned at
The amount loaned at 8% is $4800.
The amount loaned at 18% is $6,200.
What are the linear equations that represent the question?a + b - 11,000 equation 1
0.08a + 0.18b = 1500 equation 2
Where:
a = amount loaned at 8%
b = amount loaned at 18%
How much was loaned at 8 and 18%?Multiply equation 1 by 0.08
0.08a + 0.08b = 880 equation 3
Subtract equation 3 from equation 2

You enter a room. 2 dogs, 4 horses, 1 giraffe, and a duck are lying on the bed. 3 chickens are flying over a chair.
How many legs are on the ground?
Answer:
36
Step-by-step explanation:
I think it’s a trick question because “legs” can also mean like chair legs that hold it up. Therefore:
2 dogs = 8 legs
4 horses = 16 legs
1 giraffe = 4 legs
And a bed: 4 legs(things that hold it up)
And a chair: 4 legs (things that hold it up)
This is assuming that the bed is a normal bed with stools holding it up
And the chair has 4 piles aswell as no missing legs in the animals… lol

We can simplify the given rational function into a linear one, the graph is below.
Which graph represents the function?
Here we have the rational function:
[tex]f(x) = \frac{4x^2 - 16}{2x - 4}[/tex]
Factorization the numerator, we get:
4x² - 16 = 0
4x² = 16
x² = 16/4 = 4
x = ±√4 = ±2
Then the numerator can be written as:
4*(x - 2)*(x + 2)
And the denominator can be rewritten as:
2x - 4 = 2*(x - 2)
Then the function becomes:
[tex]f(x) = \frac{4*(x + 2)*(x - 2)}{2*(x - 2)} \\\\f(x) = 2*(x + 2) = 2x + 4[/tex]
