After 6 years, Federico earned $1485 in simple interest from a cd into which he initially deposited $ 9000. What was the annual interest rate of the cd?A. 2.75% B.5.5% C. 8.25 D.11%
Answers
I=Prt
I=interest earned
P= principal
r= rate in decimal form
t= time in years
I=Prt
1485=9000(r)(6)
1485=54000r
Divide by 54000:
0.0275=r
Change to percent form:
r=2.75%

Answer:
- domain (-∞, ∞)
- range (-∞, 4]
- increasing (-∞, 0)
- decreasing (0, ∞)
- constant (only at x=0, not on any interval)
Step-by-step explanation:
The graph is of the equation y = -x^2 +4. It is a polynomial of even degree, so has a domain of all real numbers: (-∞, ∞).
The vertical extent of the graph includes y=4 and all numbers less than that:
range: (-∞, 4]
The graph is increasing to the left of its vertex at x=0, decreasing to the right.
increasing (-∞, 0); decreasing (0, ∞)
There is no interval on which the function is constant. It has a horizontal tangent at x=0, but a single point does not constitute an interval.
Final answer:
The domain of a function refers to all possible inputs while the range comprises all potential outputs. The function increases, decreases, or remains constant when the respective slope is positive, negative, or zero. I've provided an explanation based on the indication of the respective slopes described in your problem.
Explanation:
To determine the domain, range, and intervals of increase, decrease, or constant for a function, we need to examine the specific input and output values as well as the curvature of the function.
Domain of a function refers to all possible input values (x-values). For example, in the probability distribution function (PDF), the domain may include all numerical values or could be expressed through a non-numerical set such as different hair colors. From the provided information, I can deduce that the domain of X is {English, Mathematics, ...} - a list of all majors offered at the university, indicating all the possible inputs of this function. The domain of Y and Z are numerical, from zero up to an upper limit.
Range of a function is all the potential output values (y-values). The range is usually derived from the domain values after undergoing certain transformations via the function. Unfortunately, without further specifics about the function, I can't provide a conclusive range.
For intervals of increase, decrease, or constant, you look at the slope of the function. A function is increasing on an interval if the y-value increases as the x-value increases. Contrary to this, a function is decreasing on an interval if the y-value decreases as the x-value increases. If the y-value remains constant as the x-value varies, the function is constant on that interval. Different parts of your provided solutions indicate the function starts with positive slope (increasing), then levels off (becomes constant).

Using the function concept, it is found that:
A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.
--------------------------------
- A function has the following format:
- In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.
- The input is x and the output is y.
- Then, the word independent completes the sentence.

Answer:
A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.
Step-by-step explanation:
We have been an incomplete statement. We are asked to complete the given statement.
We know that a function is a relation between two sets. A relation is known as function when each input in the domain has exactly one specific corresponding output.
We also know that independent variable is known as input of function and dependent variable is known as output of function.
Therefore, the correct word for given statement would be independent variable.
