Answer:
13.2 years
Step-by-step explanation:
The decay rate is 15%, so the decay factor is 1 - 15% = 0.85. Then the exponential equation for the value is ...
v(t) = 85000·0.85^t
We can set v(t) = 10,000 and solve for t:
10000 = 85000·0.85^t
10000/85000 = 0.85^t . . . . divide by 85000
log(2/17) = t·log(0.85) . . . . . .reduce fraction, take logs
t = log(2/17)/log(0.85) ≈ 13.2
It will take about 13.2 years for the value to fall below $10,000.
_____
Such a question is nicely answered by a graphing calculator.
Answer:
x=2
Step-by-step explanation:
5×2=10-2=8
You subtract add two to both sides, giving you 5x=10
Divide the 10 by 5 and you get 2.
Answer
Find out the what is the ratio of students with pets to students without pets .
To prove
As given
of 60 students, 24 students have a pet.
Thus Total number of student = 60
students have pets = 24
students without pets = 60 - 24
= 36
Now ratio of students with pets to students without pets .
simplify the above
Therefore the ratio of students with pets to students without pets be 2:3 .
Hence proved
Answer:
angle NXo= 90-67 = 23
angle NXP=90
angle MXN= 70 + 67+ 23
MXO= 70 + 23
