Answer:
numbers:letters
5:4 (numbers:letters form)
Step-by-step explanation:
There are 5 numbers in the password and 4 letters
Hopefully this helps :)
20875.2 All you have to do is plug in the numbers to the equation.
The sequence is going up by 4 so u have to multiply each term by four and the -5 is it’s 0th term as well it’s beginning so you have to input that in the equation as well
4(50) - 5 = 200 - 5 = 195
I’m not very good at explaining so I hope u get it
Answer:
196
Step-by-step explanation:
The discriminant (Δ) is given by:
![\Delta = b^2-4ac](https://tex.z-dn.net/?f=%5CDelta%20%3D%20b%5E2-4ac)
Where the polynomial is in the form:
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
In this problem, a = 1, b = 0, and c = -49. Thus, plugging it into the formula:
![\Delta = 0^2-4(1)(-49) = -(-196) = 196](https://tex.z-dn.net/?f=%5CDelta%20%3D%200%5E2-4%281%29%28-49%29%20%3D%20-%28-196%29%20%3D%20196)
Thus, the discriminant of x² – 49 = 0 is 196.

Option C. ![26\ units](https://tex.z-dn.net/?f=26%5C%20units)
Step-by-step explanation:
we know that
Triangles ADE and ABC are similar by AA similarity postulate
AB=2AD
Apply proportion
![\frac{AD}{AB}=\frac{8x-6}{12x+4}\\ \\\frac{AD}{2AD}=\frac{8x-6}{12x+4}\\ \\\frac{1}{2}=\frac{8x-6}{12x+4}\\ \\12x+4=16x-12\\ \\16x-12x=4+12\\ \\4x=16\\ \\x=4\ units](https://tex.z-dn.net/?f=%5Cfrac%7BAD%7D%7BAB%7D%3D%5Cfrac%7B8x-6%7D%7B12x%2B4%7D%5C%5C%20%5C%5C%5Cfrac%7BAD%7D%7B2AD%7D%3D%5Cfrac%7B8x-6%7D%7B12x%2B4%7D%5C%5C%20%5C%5C%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B8x-6%7D%7B12x%2B4%7D%5C%5C%20%5C%5C12x%2B4%3D16x-12%5C%5C%20%5C%5C16x-12x%3D4%2B12%5C%5C%20%5C%5C4x%3D16%5C%5C%20%5C%5Cx%3D4%5C%20units)
