The average rate of change over the interval [9,10] is greater by 6490.
The average rate of change of a polynomial is the slope of the function.
The average rate of change over the interval [7, 9] is the slope between ( 7, f(7) ) and ( 9, f(9) )
where f(7) and f(9) is the value of the function at 7 and 9.
So, the slope between ( 7, 1852 ) and ( 9, 3878 )
= (3878-1852)/(9-7)
= 2026/2
= 1013
Similarly,
The average rate of change over the interval [4, 6]
i.e. slope between ( 4, f(4) ) and ( 6, f(6) )
So, the slope between ( 4, 358 ) and ( 6, 1178 )
= (1178-358)/(6-4)
= 820/2
= 410
and
1013-410 = 603
So, the polynomial is 603 greater than the average rate of change over the interval [7, 9] than the interval [4, 6]

Do YOU currently have earned or unearned income? Where do you get this money from?
Answer:
Earned Income
Step-by-step explanation:
I get this money from chores I do around the house and my side job of selling sandwiches to my classmates (this is just an example you can personalize it)
if i make $2949 a second how long will it take to get $2,000,000
it will take approximately 678.24 seconds, or about 11 minutes and 18 seconds, to earn $2,000,000 if you make $2949 per second.
Why it is?
We can use a simple formula to solve this problem:
Time = Amount / Rate
where Amount is the amount of money you want to earn ($2,000,000) and Rate is the rate at which you earn money per second ($2949).
Plugging in these values, we get:
Time = $2,000,000 / $2949 per second
Time = 678.24 seconds
Therefore, it will take approximately 678.24 seconds, or about 11 minutes and 18 seconds, to earn $2,000,000 if you make $2949 per second.

A 6-pack of bouncy balls costs $2. 76. What is the unit price?
A 6 pack of bouncy ball costs 2.76$ and the unit price of a bouncy ball is $0.46
To find the unit price of the bouncy balls, we need to divide the total cost by the number of bouncy balls in the pack. Since there are 6 bouncy balls in the pack and the cost is $2.76, we can calculate the unit price as follows: Unit price = total cost ÷ number of units
Unit price = $2.76 ÷ 6
Unit price = $0.46
Therefore, the unit price of a bouncy ball is $0.46.
Unit price is a measure of the cost of a single unit of a product. It is calculated by dividing the total cost of a product by the number of units in the package. The unit price is helpful when comparing the costs of different package sizes or brands of the same product. It allows consumers to make informed decisions about their purchases based on the value they receive for their money. Unit pricing is required by law in some countries, including the United States, to ensure transparency in pricing and to protect consumers from deceptive marketing practices. Overall, knowing the unit price of a product can help consumers save money and make more informed purchasing decisions.

The ratio of the sides of two similar is 2/3. The area of the smaller triangle is 36cm. Find the area of the larger triangle?
Answer:
[tex]\text{Area of larger $\triangle$} = 81 \:cm^2[/tex]
Step-by-step explanation:
Given.
Ratio of corresponding sides of two similar triangles = 2:3 or [tex]\dfrac{2}{3}[/tex]
Area of smaller triangle = 36 cm²
By the property of area of two similar triangle,
Ratio of area of both triangles = (Ratio of their corresponding sides)²

What is percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.
Let's use "x" to represent the total number of pages in the book.
According to the problem, Daniel has read 80 percentage of the book, which means he has read -
8/100 = 0.8x pages
He still has 8 pages left to finish, so we can set up an equation -
0.8x + 8 = x
Solving for x, we can subtract 0.8x from both sides -
0.8x + 8 - 0.8x = x - 0.8x
8 = 0.2x
