Answer:
19
Step-by-step explanation:
1 m = 100 cm or 0.01 m = 1 cm
1900/100=19
To find the roots of a quadratic equation
you need to use the quadratic formula
![x_{1,2} = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}](https://tex.z-dn.net/?f=%20x_%7B1%2C2%7D%20%3D%20%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D%20)
This implies that if
the equation has no solutions, if
the equation has one double solution, and two distinct solutions otherwise.
So, the pseudocode could be something like this:
double delta = b*b - 4*a*c;
if (delta < 0) print ("There are no real solutions!");
else if(delta = 0) {
double x = -b/(2*a);
print("There is a double solution: " + x);
} else {
double det = sqrt(delta);
double x1 = (-b+det)/(2*a);
double x1 = (-b-det)/(2*a);
print ("The two solutions are " + x1 + "and" + x2);
}
There are a bunch of ways to do it but a couple would be 4 tens and 9 ones, or 49 ones. I hope this was helpful.
Intersecting chords are chords that intersect one another at a point
The value of n is -18
<h3>How to determine the value of n</h3>
Using the intersecting chord theorem, we have:
![\frac{7}{n + 4} = \frac{5}{n + 8}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7Bn%20%2B%204%7D%20%3D%20%5Cfrac%7B5%7D%7Bn%20%2B%208%7D)
Cross multiply
![7n + 56 = 5n + 20](https://tex.z-dn.net/?f=7n%20%2B%2056%20%3D%205n%20%2B%2020)
Collect like terms
![7n - 5n =20 - 56](https://tex.z-dn.net/?f=7n%20-%205n%20%3D20%20-%2056)
Evaluate the differences
![2n =-36](https://tex.z-dn.net/?f=2n%20%3D-36)
Divide through by 2
![n = -18](https://tex.z-dn.net/?f=n%20%3D%20-18)
Hence, the value of n is -18
