a) Call the savings before the increase, S ....and we have
S + 25% S = 517
S + .25S = 517
1.25S = 517 divide by 1.25
S = 517 / 1.25 = $413.60
b) 517 - 413.60 = $103.40 more saved after increase
....And just when I was gonna' give you 5 points.....
This happened → I beat you chris,
Nah nah na na nah !!!
I think you have
log25 = x
To solve this
x = log 5 / log 2 ≈ 2.32
The vertex is at x = 3
And the x coordinate of the vertex = -b / [2a] = 3 → b = -6a
The product of the roots = c /a = 8 → c = 8a
And we know that
a(1)^2 - 6a(1) + 8a = 6
3a = 6 →
a = 2 b = -12 c = 16
Here'a a graph : https://www.desmos.com/calculator/flafi02koq
[√6 - i √2 ] / [ i √3 ] mult. top/ bottom by i √3
[ i √18 - i^2 √6 ] / [ i^2 *3 ] =
[3i√2 + √6 ] / [ - 3] =
- [ 3 i√2 + √6 ] / 3
" 42 "
9 (2d) = 18d
(-5,-9)
We can reflect twice to find the answer
First...across x ...... (-5,-9) → (-5, 9)......
And (-5, 9) across y → ( 5, 9 ) .....and (5, 9) is the answer.....
Note.......any successive term divided by its predecessor =
an + 1 / an = 1/2 = r
Example..... -82 / -164 = 1/2
I looked at this earlier and I agree wiih EP......
Each side of the base = 8
Thus....each face can be divided into two congruent right triangles..........and each of these would have a "bottom" leg = 4.....and in each case, the lateral edge of 4 would serve as a hypotenuse....however......a leg can never = a hypotenuse.....
