Checking for a perfect cube

3.1 21x3-6x2+7x-2 is not a perfect cube

Trying to factor by pulling out :

3.2 Factoring: 21x3-6x2+7x-2

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1: 7x-2

Group 2: 21x3-6x2

Pull out from each group separately :

Group 1: (7x-2) • (1)

Group 2: (7x-2) • (3x2)

-------------------

Add up the two groups :

(7x-2) • (3x2+1)

A used car salesman wants to be able to predict the resale value of a car based on the age of the car. What type of variable is the age of the car? * A. Categorical B. Quantitative (Discrete) C. Quantitative (Continuous) D. Cannot be determined without seeing the data.

Answers

Answer:

D. Cannot be determined without seeing the data.

Step-by-step explanation:

Option “D” is correct because age is a quantitative variable but if we look at the exact number or exact age of the car then the car’s age is quantitative discrete but if we look at the age of the car by going a number of years then it will be continuous. Therefore, without getting the exact information of the age of the car we cannot predict the type of variable. So the option “D” best fit for the answer.

Final answer:

The age of the car in a resale assessment is considered a Quantitative (Continuous) variable due to its numerical value and its ability to take any value within a given range, including fractions of a year.

Explanation:

The age of the car is a Quantitative (Continuous) variable. This is because age is a numerical value that can take any value within a given range, including fractions of a year. Continuous data can have an infinite number of values within a selected range, and age of a car could be represented in years, months, or even days if needed for precision sake in the case of used car sales, making it continuous.

Determine the derivative of the following and leave the answer with positive exponentsAy/ax if y=5x+√x to the exponent 5/2x²

Answers

Hello,

It was a long time i have done this.

y=(5x+√x) ^(2.5 x²)

ln y= 2.5x² ln (5x+√x)

We use:
d (ln y)/dx=1/y* dy/dx

y'/y= 5x*ln(5x+√x)+2.5x²*1/(5x+√x) *(5+1/(2√x))

y'=(5x+√x) ^(2.5 x²)*[5x*ln(5x+√x)+2.5x²*1/(5x+√x) *(5+1/(2√x))]

How to show your work to solve 3r^2-16r-7=5

Answers

OK so 3r^2-16r-7=5
Subtract five from both sides
3r^2-16r-7-5=0
Add like terms
3r^2-16r-12=0
Factorise it, this means putting it into brackets
(3r + 2)(r - 6)
Find out what multiplies to make negative twelve but adds to make negative sixteen
However none of the terms do this so we put negatives next to the "r"s
(-3r + 2)(-1r - 6)
The answer is r=6

Answer:

Step 1: Subtract 5 from both sides.

3r2−16r−7−5=5−5

3r2−16r−12=0

Step 2: Factor left side of equation.

(3r+2)(r−6)=0

Step 3: Set factors equal to 0.

3r+2=0 or r−6=0

r=−2/3

or r=6

Answer:

r=−2/3

or r=6

Twins Lidia and Henry collected snow globes. When they left for college, they split the collection, such that Lidia got 75% of the snow globes. If Lidia got 460 more snow globes than did Henry, how many snow globes did Henry get?

Answers

Answer:

230

Step-by-step explanation:

Okay, so if Lidia got 75% means that Henry got 25%, right?

Then Lidia got 50% more than Henry did. So that 460 = 50%

So Henry got 25% which is 460/2 = 230 snow globes
