Answer:
-56/9
Step-by-step explanation:
Let p and q be the roots of the equation.
So, here's how we're gonna work it out:
Vieta's formulas give us the sum and the product of the roots of a quadratic equation. Using them we obtain:
- p + q = -b / a = - 4 / 3
- p × q = c / a = 12 / 3 = 4
The answer to this question is a simple one.
First, you need this formula :
<span>(<span>x0 </span>+ dx<span>)^2
You need to substitute the values of the formula
Then,.
</span></span><span>(dx)^2 = (0.06)^2
So the answer to this question is .0036
I hope my answer helped you in somehow. </span>
3/4 x -18 = 1/4 x -4
subtract 1/4 x from each side
3/4 x -1/4 x -18 = 1/4 x- 1/4 x -4
2/4 x - 18 = -4
add 18 to each side
1/2 x -18 + 18 = -4 + 18
1/2 x =14
multiply by 2 on each side
2* 1/2 x = 14 * 2
x =28
If the length of JK is 16.4 miles, it will be diameter of this circle, the radius will be JK/2 = 8.2 miles
As we know the length of circle is 2π*r in this case r = 8.2
The arc JM is 1/4 length of the whole circle so arc JM = (2π*8.2)*(1/4) = 2π*8.2/4 = π*8.2/2 = π*4.1
if we assume that π=3.14 the answer will be 3.14 * 4.1 = 12.874.... And as the answer needs to be rounded to the nearest tenth it will be 12.874≈12.9
So the answer will be 12.9
The answer is 486.6
There are 8,760 hours in a year, so 18 divided by 8,760 would = 486.6
