8x + 6=4x + 38
4x = 32
x = 8
<B = 4x + 38 = 4(8) + 38 = 70
Set each binomial equal to zero to solve.
2n + 3 = 0
2n = - 3
n = - 3 / 2
n - 4 = 0
n = 4
So n = -3/2, 4
The problem wants to calculate the percentage error of the measurement of 7cm and if the measurement is uncertain we could use the formula of getting the error by margin of error over measurement time 100% and base on the data, the error would be if the margin error is 7.5 is 107 %. I hope you are satisfied with my answer
Answer:
= A(t) = 120000(1.06)^t t = 1 year
We just add ^12 to equal 1/12 months.
Then use the notation below.
Step-by-step explanation:
We simply want to write an equivalent form of the same equation that will allow for the time period to be calculated in years.
For one year, t = 1, we want it to grow 6% = 1.06
Yearly Rate of Growth annual equation: = 7200
P(i) 7200/ 120000 x 100% = 6% per year growth rate
the yearly growth factor is 1 + appreciation rate = 1+i =1+0.06= 1.06
So time in years can be added to t
= A(t) = 120000(1.06)^t t = 1 year
The yearly growth factor = 1.06
To equate monthly we add the exponent t*12*1/12 before 120000(1.06)^t
then add 1/12 to replace ^t = monthly, or just keep the t= time
A(t) = 120000(1.06)^12t
