All these can be done without a calculator by taking the factors of ten separately. We count zeros for the exponents.


I'll leave the rest for you or someone else, sorry.
Answer:
x<-5 <--------o open circle
Step-by-step explanation:
Answer:
a. f(1) = -4
b. One value of x for which f(x) = -1 : 2 (or -2)
Step-by-step explanation:
a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.
b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.
I hope you find my answer and explanation to be helpful. Happy studying.
<span>The CD pays interest at 5.5%, presumably compounded annually at the end of each year. So over the two years, the principal balance will have grown by a factor of 1.055*1.055 = 1.113. Therefore, in order to have $8000 at the end of that time, one would need to start with 8000/1.113 = $7187.60.</span>
Let there be 30 days in a month.
Days in 8 months = 8 x 30 = 240
240/360 = 2/3
The answer is C.
