Simplify the following expression. Write the resulting polynomial in descending order.
–2x(1–3x) + (2x + 3)(3x – 2)
Answer: 4x² + x - 2
Step-by-step explanation: First distribute the -2x into (1-3x) which = -2x + 6x²
Now let's work on the second part:
Distributing (2x + 3) to (3x - 2) = 6x² - 4x + 9x - 6. Combining like terms: 6x² - 4x + 9x - 6 --> 6x² + 5x - 6. Now let's combine the like factors of our two equations which equals
12x² + 3x - 6. Now reduce by dividing by 3 which gives us the final answer of:
4x² + x - 2.
What is the completely factored form of 3x5 – 7x4 + 6x2 – 14x?
(x Superscript 4 Baseline + 2 x) (3 x minus 7)
x Superscript 4 Baseline (3 x minus 7) (2 x minus 1)
x (x cubed + 2) (3 x minus 7)
x (3 x Superscript 4 Baseline minus 7 x cubed + 6 x minus 14)
Answer:
x(x³ + 2)(3x - 7)
Step-by-step explanation:
I got it right
The solution is Option D.
The equation is simplified as A = x ( 3x⁴ - 7x³ + 6x - 14 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 3x⁵ - 7x⁴ + 6x² - 14x be equation (1)
Now , on factorizing the equation , we get
Taking the common factor as x in the equation , we get
A = x ( 3x⁴ - 7x³ + 6x - 14 )
Therefore , the value of A is x ( 3x⁴ - 7x³ + 6x - 14 )
Hence , the equation is A = x ( 3x⁴ - 7x³ + 6x - 14 )

A manufacturer who is considering the implementation of a one-week training program for all new employees decides to test the program with the next 100 employees hired, and then compare their productivity rate to the productivity rate of new employees based on past records–a rate that is normally distributed with a mean of 60 and a standard deviation of 8. The new program needs to produce a minimum improvement of 4 to be considered worthwhile. What is the comparison distribution's standard deviation?
Answer:
0.8
Step-by-step explanation:
From the given information:
The population mean = 60
The standard deviation = 8
The sample size = 100
The sample distribution which follows a normal distribution is the set of values taken by this statistic on each sample from the same population.
The standard deviation of the comparison distribution's = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex]
The standard deviation of the comparison distribution's = [tex]\dfrac{8}{\sqrt{100}}[/tex]
The standard deviation of the comparison distribution's = 8/10
The standard deviation of the comparison distribution's = 0.8

mia has 14 coins in her pocket that total $1.10. what are the coins in her pocket
Answer: Either 8 dimes and 6 nickles, or 4 quarters and 10 pennies. Both combinations add up to $1.10.
Have a nice day
The 14 coins can be:
- 8 dimes and 6 nickels
Or
- 10 pennies and 4 quarters
Given,
14 coins make up $1.10
We need to find what are the 14 coins.
What are the different types of coins that make up a dollar?We have,
100 pennies = $1
20 nickels = $1
10 dimes = $1
4 quarters = $1
Find the coins that are worth $1.10
We have
10 dimes = $1
So,
1 dime = $0.10
8 dimes = $0.80 _____(1)
20 nickels = $1
So,
1 nickels = $0.05
6 nickels = $0.30 _____(2)
100 pennies = $1
10 pennies = $0.1 _____(3)
4 quarters = $1 ______(4)
From (1) and (2)
8 dimes + 6 nickels = $0.80 + $0.30
14 coins = $1.10
From (3) and (4)
10 pennies + 4 quarters = $0.1 + $1
14 coins = $1.10
Thus the 14 coins can be:
- 8 dimes and 6 nickels
- 10 pennies and 4 quarters

is 9.90 biger or less or equal 9.9
Answer:
Equal
Step-by-step explanation:
9.90 = 9.9
The difference is just decimal places
Evaluating the two values, both numbers 9.90 and 9.9 are equal.
The value 9.90 is written to 2 decimal places as the value of 0 in the hundredth place adds no value in terms of size to the number. The other value 9.9 is written to 1 decimal place. Hence, both values are of equal size.Hence, the values 9.90 and 9.9 are equal.

in general how does perimeter "a" affect y=a(b x-c)?
A affects the slope of the graph.
When a is less than 1, the amplitude of the graph decreases which causes the slope of the graph to appear more flat.
When a is greater than 1, the amplitude of the graph increases which causes the slope of the graph to appear more steep.
