Classify the polynomial by term and degree
4x - 9x2 + 2x3 + 15
Answer:
Cubic Polynomial
Step-by-step explanation:
The degree is the highest exponent in the equation. (So, 3.)
This makes it cubic.
Anything above three terms is just considered a polynomial.
Hence, Cubic Polynomial.

Catalina and Terri are each saving money to buy a car. Catalina puts $1000 in a safe at home and adds $25 every month. Terri puts $500 in a savings in a savings account at the bank that earns 3.2% interest each month on the total amount of money in the account. For each person, the total amount saved is a function of the number of months. Which of these relationships is a linear function?
Answer:
Catalina´s example is linear
please help, I don't understand this
After substitution in the first equation :
7x + x +21 = -19
= 8x + 21 = -19
by subtracting 21 :
8x = -19 - 21
8x = -40
by dividing over 8 :
x = -5
after substitution in the second equation :
2y = -5 + 21
2y = 16
by dividing over 2 :
y = 8

i need help with my math homework can someone help
Answer:
okay
Step-by-step explanation:
For each one-year period after a car was purchased, its value at the end of the year was 17% less than its value at the beginning of the year. State whether the value of the car as a function of time after it was purchased is best modeled with a linear function, a quadratic function, or an exponential function and explain why. Enter your answer and your explanation in the space provided. If the value of the car 2 years after it was purchased is $17,842.51, what was the value of the car when it was purchased?
Answer:
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
The Value of car when it is purchased = $25,900
Step-by-step explanation:
As given,
The value at the end of the year was 17% less than its value at the beginning of the year.
⇒ value at the end of the year = (100% - 17% ) = 83% of value at the beginning of the year.
Now,
Let the Value of car when it is purchased = x
So,
Price at the end of 1 year = 83% of x = 0.83x
Price at the end of 2 year = 83% of 0.83 x = (0.83)² x
Price at the end of 2 year = 83% of (0.83)² x = (0.83)³ x
and so on
Price at the end of n years = (0.83)ⁿ x
∴ we get
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
Now,
Value of car after 2 year = (0.83)² x = $17,842.51
⇒0.6889x = $17,842.51
⇒x = [tex]\frac{17,842.51}{0.6889}[/tex] = $25,900
∴ we get
The Value of car when it is purchased = x = $25,900
8. Standard to Slope Intercept Form
Put the following equation of a line into slope-intercept
form, simplifying all fractions.
6x + 15y = -15
Answer:
-2/5-1
Step-by-step explanation:
6x+15y=(-15)
subtract both sides by (-6x)
now the equations becomes: 15y=(-6x)-15
divide both sides by 15, since -6 cannot evenly we just leave it as a fraction
Equation becomes y= -6/15x-1
Then simplify it down to y= -2/5x-1
42.Anna pours herself some room-temperature soda from a bottle and adds four ice cubes. In a few minutes the ice cubes are smaller and the soda is much colder. Which of the following best explains the change in temperature of the soda?
A. Heat flowed from the soda to the ice cube and caused it to partially melt.
B. Coldness flowed from the ice cube to the soda, making the soda cooler.
C. The cold water from the melting ice went into the soda, replacing the warmer water that was in the soda
D. The water from the melting ice makes the soda more dilute, and the lower concentration makes the temperature lower.
and send me link for explenation
Answer:
Option A
Step-by-step explanation:
According to the second law of thermodynamics, heat always flows from hot to cold places, unless work is done on the system. In this case the ice is colder than room temperature, and therefore the heat flows from the soda to the ice cube. The ice cube absorbs the heat, and partially melts.

Write a ratio, in the simplest form and a percent for the shaded area (there's a 5x4 box and 6 cubes are shaded)
Answer:
[tex]\%Percent = 30 \%[/tex]
Step-by-step explanation:
Given
[tex]Shaded = 6\ cubes[/tex]
[tex]Box = 5\ x\ 4[/tex]
Required
Determine the percentage of the shaded cubes
First, we calculate the number of boxes:
[tex]Box = 5\ x\ 4[/tex]
Express as multiplication
[tex]Box = 5\ *\ 4[/tex]
[tex]Box = 20[/tex]
This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:
[tex]\%Percent = \frac{Shaded}{Box} * 100\%[/tex]
[tex]\%Percent = \frac{6}{20} * 100\%[/tex]
[tex]\%Percent = \frac{6* 100}{20} \%[/tex]
[tex]\%Percent = \frac{600}{20} \%[/tex]
[tex]\%Percent = 30 \%[/tex]
30% were shaded
