Answer:
the answer is B 43 i think im right nut please let me know
Step-by-step explanation:
PLEASE GIVE ME BRAINLYEST
in right angle traingle two angle are equal
so.x=y
in triangle
x+y+90=180(sum of interior angle of triangle)
2x=180-90
x=90/3=45°
We know that
<span>This problem can be represented through the following equation
</span>
A = A₀(1/2)^t/h
where
A-----------> is the amount of substance left after time t
A₀ ----------> is the original amount---------> 2 g
h-------------> is the half-life-----------> 8 days
for A=0.04 g
t=?
0.04 = 2(1/2)^t/8
0.02 = (1/2)^t/8
Take ln on both sides:
ln(0.02) = ln [(1/2)^t/8]
ln(0.02) = (t/8)(ln 1/2)
t = 8*ln(0.02)/ln(1/2)
t = 45.15 days
the answer is 45.15 days
Answer:
See below
Step-by-step explanation:
<u>Given:</u>
- f(x)= { 3x+1, if −9 < x ≤ −2
- f(x)= {−5, if. −2 < x ≤ 1
- f(x)= { x−6, if 1 < x < 7
<u>Combination of domain for the function is the following union:</u>
- (-9, 2]∪ (-2, 1]∪(1, 7) = (-9, 7)
<u>Group of answer choices:</u>
The domain is the depth interval (−26, 1).
- incorrect as (-26, -9) interval is not covered in given function
The domain is the depth interval (−9, 1].
The domain is the set of times −9 < x < −2, −2 < x < 1, and 1 < x < 7.
- incorrect as doesn't include x = -2 and x = 1
The domain is the time interval (−9, 7).
- This is correct as it is same with the domain set we got above.
