How do I convert a polynomial into standard form?

Mathematics
2 answers:
Alisiya [41]3 years ago

Answer:

1) Write the term with the highest exponent first

2) Write the terms with lower exponents in descending order

3) Remember that a variable with no exponent has an understood exponent of 1

4) A constant term (a number with no variable) always goes last.

 Step-By-Step Explanation:

Here is an example:

1) 6y3+4y5-2y2-6y+8y4+7

The highest exponent is the 5, so that entire term must be written first:4y5

The next highest exponent is the 4 so that term comes next. So far we have 4y5+8y4

The next highest exponent is the 3 so add that term to get

4y5 +8y4+6y3

Then comes 2. Notice that this term is negative, so don't forget to include the negative sign:

4y5 +8y4 +6y3-2y2

Remember that term has an understood exponent of 1 so it comes next. 4y5+8y4+6y3-2y2 -6y

The constant term (a number with no variable) always comes last so the final answer is:

4y5+8y4+6y3-2y2-6y+7

Hope this Helps! Tell me if I'm wrong

Answer:

One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to right.

Safara wants to rent a bicycle the graph shows the cost for renting a bicycle for different lengths of time. What is the slope o
enot [183]

The slope of the line will be equal to 30.

Slope of a line may be defined as the steepness of a curve. Slope of line can be positive, negative or zero. Slope of a line is used to determine the equation of the line which is given as y = mx + b where m is the slope, b is y intercept and x and y are independent and dependent variables respectively. The slope of a line on points (x₁, y₁) and (x₂, y₂) is given by the formula, m = y₂ - y₁/x₂ - x₁.

According to the question the value of points is (x₁, y₁) = (0, 0) and (x₂, y₂) = (2, 60).

Now, the slope can be calculated as

m = (60 - 0)/(2 - 0)

=> m = 60/2

=> m = 30 which is the required slope.

Fantom [35]

In linear equation, 15.2% did the total number of students on the honor roll decrease.

What in mathematics is a linear equation?

  • A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
  • Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

50 × 24% = 12

50 × 14%= 7

12+ 7 = 19

50+75 = 125

19 ÷125= 15.2%

The following function represents the value of a motorcycle, in dollars, after x years: f(x) = 19,000(0.91)x
Semenov [28]

Answer:

Option C.The decrease in the value of the motorcycle, which is 9%

Step-by-step explanation:

we have a exponential function of the form

f(x)= ab^x

where

a is the initial value

b represents growth or decay factor

If b >1 then it is an exponential growth

if 0<b<1 then it is an exponential decay

In this problem

a=$19,000

b=0.91 -----> it is exponential decay factor

Find the rate of decrease r

b=(1-r)

substitute

0.91=1-r

r=1-0.91=0.09

Convert to percentage

0.09*100=9%

therefore

0.91 represent the decrease in the value of the motorcycle, which is 9%
