The answer if we go by solving only for "r" Will be -2, in other words r=-2
...it is a triangle...if it's asking to prove it's not a certain type of triangle, I can do that, but the only requirement for a triangle to exist is that the 2 shorter sides added together are greater than the longest side.
Answer:
Hence final answer is $15.17
Step-by-step explanation:
Given that Dirk opened up a savings account with $600.
So P=$600
"At a yearly interest rate of 5 percent"
Means r=5% = 0.05
"compounded monthly" means n=12
i= monthly rate of interest = r/n=0.05/12
"how much interest will Dirk earn in six months." means find Interest when time is 6 months
Plug these values into compound interest formula:





A=615.169372966
which is approx
A=615.17
Now interest earned will be difference of A and P
Interest =A-P=615.17-600=$15.17
Hence final answer is $15.17
Answer:
117.8 in.
Step-by-step explanation:
To find the perimeter, add all the side lengths together. If we do that, we get 117.8 in, which is the answer.
Answer: 11
Step-by-step explanation:
c(4)=-7+6(4-1)
c(4)= -7 + 6(3)
c(4)= -7 +18
c(4)= 11
