Answer:
Your answer to the fig. would be 14cm^2.
Adding area of both rectangles,
(8+6) cm^2
= 14cm^2
Hope it helps!!
It looks like the first 1 is the first problem, problem #1. (because of the period)
If this is the case, then the second sequence is 1, 0, -1, ...
1-1=0
0-1=-1
-1-1=-2
-2-1=-3
-3-1=-4
The sequence would then be 1, 0, -1, -2, -3, -4, ...
Answer:
3 sides
Step-by-step explanation:
Two sides will have the same angle measurement while the third angle will be different.
The amount of the substance (At) at any time t is calculated through the equation,
At = (A0)(e^-kt)
where A0 is the initial amount and k is constant.
For the half-life,
ln (At / A0) = ln 0.5 = -k(5270 years)
The value of k is 1.3153x10^-4 / year.
Substituting this value to the same equation, where At = 0.25A0
ln 0.25 = -(1.3153 x 10^-4)(t)
The value of t from this equation is 10540 years. The closest value to this is letter A.
12.5=5x-3 1/3
5x=12.5+3 1/3
5x=15 5/6
5x=95/6
x=95/30 or simplied x=19/6
