Answer:
This is an error (TypeError) that is displayed by the Python interpreter when one of the parameter in a slice function is not a value of type integer or None.
For example:
>>> a = 'welcome'
>>> a[2.2:3]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: slice indices must be integers or None or have an __index__ method
The error occur because the value 2.2 is not an integer or None
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
An example will help to explain this.
f(x) = 3x^2.
The number multiplying the power term x^2 is the coefficient - it is 3.
The degree is the value of the exponent. here it is 2, the second degree.
Another example:
f(x) = 1.2 x^3: the coefficient is 1.2 and the degree is 3 , the third degree.
Answer:
314.2 cm²
Step-by-step explanation:
The area of the circular cross section of the pipe is given by A = πd²/4 where d = diameter of pipe = 20 cm
So, A = πd²/4
substituting the value of d into the equation, we have
A = π(20 cm)²/4
A = π400 cm²/4
A = 100π cm²
A = 314.16 cm²
A ≅ 314.2 cm²
Explanation:
M is the slope of the equation, basically how much the line goes up or down each unit. To calculate the slope, we divide the rise over the run or
B is the y-intercept or when the line crosses the y-axis.
1. We can see the line moves 1 unit up every 3 units right. The line crosses the y-axis at (0,-4)
m = 1/3
b = -4
2. We can see the line goes 3 units down every 2 units right. The line crosses the y-axis at (0,4)
m = -3/2
b = 4
3. We can see the line goes 1 unit down every 4 units right. The line crosses the y-axis at (0,4)
m = -1/4
b = 4
4. We can see the line goes 1 unit down every 4 units right. The line crosses the y-axis at (0,2)
m = -1/4
b = 2
5. We can see the line goes 1 unit down every 1 unit right. The line crosses the y-axis at (0,1)
m = 1
b = 1
Step-by-step explanation:
the correct answer is option c
