Answer:
Step-by-step explanation:
Here are the steps required to solve a quadratic using the quadratic formula:
Example 1 – Solve: x²-8x+14=0
Step 1: Identify a, b, and c and plug them into the quadratic formula. In this case a = 1, b = –8, and c = 14.
Step 2: Use the order of operations to simplify the quadratic formula.
Step 3: Simplify the radical, if you can. In this case you can simply the radical into:
Step 4: Reduce the problem, if you can. In this case you can reduce the entire problem by 2.
Dy/dx=25, 35, 45, 55
d2y/dx2=10,10,10 (this constant just proves that it is a quadratic relation)
Now we can set up a system of equations for ax^2+bx+c
16a+4b+c=80, 9a+3b+c=45, 4a+2b+c=20 getting differences
7a+b=35, 5a+b=25 and again
2a=10, a=5, making 7a+b=35 become:
7(5)+b-35, b=0, making 4a+2b+c=20 become:
4(5)+2(0)+c=20, c=0 so
y=5x^2
So the constant of variation for this quadratic is 5.
0.95 rounded to the nearest hundredth (I assume that's what you mean) would still be 0.95. Since I saw your other question, I think you're looking for 0.095 rounded to the nearest hundredth, which is 0.10.
Answer:
if you're sating 200 tens(10), then it equals 2000
Step-by-step explanation:
because you'd multiply them, and 200 times 10 equals 2000.
and if you ment 200 ton, the it's 400000. because a ton is 2000, so 200 times 2000 equals 400000
