Answer:
x=[15:-5:-25]'
Step-by-step explanation:
In order to create a vector you need to use this command:
x = [j:i:k]'
This creates a regularly-spaced vector x using i as the increment between elements. j is the initial value and k is the final value. Besides you need to add the character ' at the end in order to convert the arrow vector in a column vector
Hi I don’t really understand can you explain a little bit please
Answer:
3/5
Step-by-step explanation:
30 + 40 + 15 + 15 = 100
40/100 will be green
100/100 - 40/100 = 60/100
60/100 will NOT be green
60 ÷ 5 = 12
100 ÷ 5 = 20
12 ÷ 4 = 3
20 ÷ 4 = 5
3/5
Answer:
The graph in the attached figure
see the explanation
Step-by-step explanation:
we have

we know that
The radicand must be greater than or equal to zero
so

solve for x
Adds 3 both sides


Multiply by -1 both sides
Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

so
The domain of the function is the interval (-∞,-3]
For x=-3 ---> the value of y=0
The range is the interval {0,∞)
therefore
The graph in the attached figure
