The graph of y=4x2-4x-1=0
Answers
Answer:
Here we have the equation:
y = 4*x^2 - 4*x - 1
And we should have the graph (you can see it below this answer)
Now we want to find the solutions of:
4*x^2 - 4*x - 1 = 0
These solutions will be the two values of x at which the graph of our function intersects the line y = 0, that is the x-axis.
Then we need to find the two values of x at which our graph intersects the x-axis.
In the graph, we can estimate the solutions as:
x = -0.2
x = 1.2
To find the exact solutions we can use the Bhaskara's equation, and we will find that the solutions are given by:
Then the two solutions are:
x = (4 + 5.66)/8 = 11.2075
x = (4 - 5.66)/8 = -0.2075

A-which temperature is warmer, -2 degrees Celsius or, -5 degrees Celsius B-Write and inequality to express the relationship between -2 and -5
Answers
Answer:
Step-by-step explanation:
On a number line, -2 appears to the right of -5, and therefore -2 is warmer than -5. (Answer A)
The difference between -2 and -5 is -2 - (-5) = 5 - 2 = 3 degrees C (Answer B)
In other words, -2 is 3 degrees C warmer than -5 degrees C.
When the fifth term of an arithmetic sequence whose  common difference is D=six and whose first term is a1 =four
Answers
Answer:
28 is the answer
Step-by-step explanation:
in an arithmetic sequence nth term An is given by the equation
[tex]an \: = a1 + (n - 1) \times d[/tex]
where A1 is first term and d is common difference. thus from the question we have
[tex]a5 = 4 + ((5 - 1) \times 6) \\ = 4 + (4 \times 6) \\ = 4 + 24 \\ = 28[/tex]

36) In the diagram, the coordinates of endpoints A and B are (-3, 9) and (9,5). Find the length from A to E?
Answers
Step-by-step explanation:
the length of AB = √(9+3)²+(5-9)²
= √144+16=√180 = 6√5
the length from A to E = ⅜× 6√5
= 2.25 √5 or 5.03
Length of AB,
→ √(9+3)² + (5-9)²
→ √144+16
→ √180
→ 6√5
Length from A to E,
→ ⅜ × 6√5
→ 2.25 √5
→ 5.03

Side note: I used the points (3,0) & (4,1)
Answer:
1
Step-by-step explain
firstly find any two point on the line
e.g. (0,-3) and (3,0)
for any straight line
[tex]m=\frac{y'-y}{x'-x}[/tex]
where m is slope, y' x' y x are coordinates of two point (x,y) and (x',y')
in this case, we can use (0,-3) and (3,0)
