C. (e-9) / 2
E-9 has to be in parentheses because of Pemdas
The key features of polynomials are the vertex, axis of symmetry, x and y intercepts.
1. The degree will help you find the end behavior.
<span>2. </span>The vertex shows you where it changes concavity.
<span>3. </span>X and y intercepts give you a couple of points of reference.
<span>4. </span>Axis of symmetry is only applicable to even degree polynomials.
Answer:
A. √10
Step-by-step explanation:
A rational number can be written as the ratio of two integers
A. √10
This cannot be simplified into the ratio of two integers, Square roots that cannot be simplified are irrational
B. -√81
- 9
-9/1 which is the ratio of two integers so it is rational
c. 5/4
This is the ratio of two integers so it is rational
d. 9.12
912/100
This is the ratio of two integers so it is rational
The answer for the exercise shown above is the first option (Option A), which is: <span>A. Jamie has $8, and she pays $2 per day to ride the bus.
The explanation is shown below:
If you write the values given in the graph in a table, you can notice that the money decreases on each day. This means that the person does not earn money, but pays. On day zero (0), the person has $8 and then that person pays $2 per day. Therefore, the option A is the answer.</span>
Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.
