Answer:
The vertex form of the equation is .
Step-by-step explanation:
You will use the equation to solve this parabola. (h, k) is the vertex. So, we plug this into the equation to get .
Then, we substitute the point as our x and y to get (a lot of simplifying was done here). Then, add 2 to the right side of the equation and isolate the to get . Finally, divide by 9 on both sides to get .
Now, substitute your back into the equation to get y = .
This is in vertex form. If the answer is needed in standard form, simply distribute and simplify to get .
Answer:
The answer is 2.5135145
Step-by-step explanation:
- The irrational number between 5,25 and 5,26
- 2.5135145...
- The number is non-terminating and non-recurring. Hence, it is an irrational number.
- A real number that cannot be expressed as a simple fraction is called an irrational number.
- It is impossible to express in terms of a ratio.
- If N is irrational, it is not equal to p/q, where p and q are integers and q is not equal to 0.
- Example: √2, √3, √5, √11, √21, π(Pi) are all irrational.
A = L * W
A / L = W <==
when A = 42 and W = 16.8
A / L = W
42/16.8 = W
2.5 = W <=== width = 2.5 inches
