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
Answer:
The answer is 172.7 centimeters.
Step-by-step explanation:
1.) There are 12 inches in a foot. Multiply 5 feet by 12 inches, the answer would be 60 inches.
2.) Add the additional 8 inches to the 60 to get 68 inches total.
3.) Multiply 68 inches by 2.54 centimeters, the answer is 172.72 centimeters.
4.) Round off your answer to the tenths decimal place to get 172.7 centimeters total.
It is B. Point 8, 4 is on the graph. B is the only one that give 8, 4 as an option.
1.) $83.99 * 0.0825= $6.929175 round that to $6.93 add $83.99 +6.93=$90.92
2). $349.65 divided by 7 = $49.95 for each tree
3)V=l*w*h 13*11*16= 2288 cubic feet
Answer:
The answer is B because x = 4 so 12x4-3=45
