Answer:
mmm idgl
Step-by-step explanation:
In this question, you have to form the equation given the formula of the volume : L x W x D
L = W+5
W = W
D = W-1
(W+5)(W)(W-1) = 20
(W^2+5W)(W-1) = 20
W^3+4W^2-5W-20 = 0
Get the roots by factoring it out.
<span>(w +4) *(w +2.236) *(w -2.236)
</span>
So the roots are: -4, -2.236, 2.236.
Since we're talking about dimensions, let's use the positive root..
L = 7.24
W = 2.24
D = 1.24
Answer:
0.00000003
Step-by-step explanation:
2+ 7 * 4 - 5 = 25
(3/6) ^ 25 = 0.00000003
Answer:
slim to none. He has to wear his shoes
Step-by-step explanation:
I hope this helps
Cos45 = cos(2*22.5) = (cos22.5)^2 - (sin22.5)^2 = (cos22.5)^2 * (1-(tan22.5)^2)
= (1 + cos45)/2 * (1-(tan22.5)^2)
Now, solve for tan22.5:
tan22.5 = sqrt(1 - 2cos45 / (1+cos45) )
