Answer:uu
-10 and -12
Step-by-step explanation:
Answer:
x > -2, or (-2, infinity)
Step-by-step explanation:
Alexis, all inputs to the natural log function y = ln x must be greater than zero.
Looking at the given y = ln (x + 2), we see that (x + 2) must be greater than zero for the reason given above.
Thus, the domain of y = ln (x + 2) is x + 2 > 0, or (by subtracting 2 from both sides) x > -2, or (-2, infinity)
Answer:
0.66
Step-by-step explanation:
The exponential growth equation is expressed as;
S(t) = S0e^kt
S(t) is the number of stores after t years
S0 is the initial number of stores
If a chain of retail computer stores opened 2 stores in its first year of operation then at t = 1, S(t) = 2. Substitute into the equation;
2 = S0e^k(1)
2 = S0e^k .... 1
Also if after 8 years of operation, the chain consisted of 206 stores, this means at t = 8, S(t) = 206. Substitute into the equation;
206 = S0e^k(1)
206 = S0e^8k .... 2
Next is to calculate the value of k
Divide equation 2 by 1;
Hence the value of k to the nearest hundredth is 0.66
The probability against selecting someone who commutes by bicycle will be 0.96.
<h3>How to compute the value?</h3>
From the information, 4% of people commute to work by bicycle.
When a person is selected randomly from the town, the odds against selecting someone who commutes by bicycle will be:
= 1 - 4%
= 96%
= 0.96
The probability is 0.96.
