8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 = 40320.
Answer:
(2,2)
Step-by-step explanation:
The graph of a function and that of its inverse should be always symmetric around the line y = x (goes at 45 degrees and crosses the origin of coordinates).
Therefore any intersection of the graphs must lie on the line y = x, which forces the x value of the intersection point to be the same as the y-value.
The only option shown where x and y have the same numerical value is the third listed option : (2,2)
Answer:
t = 6.3
Step-by-step explanation:
N=Noe^(-kt)
No = 14 grams
k = .1092
We want to find t when N = 7 or 1/2 of 14
N=Noe^(-kt)
7 = 14 e ^ (-.1092t)
Divide each side by 14
1/2 = e ^ (-.1092t)
take the natural log of each side
ln (1/2) = ln e ^ (-.1092t)
ln (1/2) = -.1092t
Divide each side by -.1092
ln (1/2)/ -.1092 = t
t≈6.3475
Rounding to the nearest tenth
t = 6.3
A = l*w
l = 2w + 4
400 = (2w + 4)*w
0 = 2w^2 + 4w - 400
Then use the quadratic equation where a=2, b=4, and c=-400.
w = <span>13.2
l = 30.4
