Answer:
A.This is the graph of the greatest integer function
E. f(-3.4)=-4
Step-by-step explanation:
The graph shown in the attachment is the parent greatest integer function.
f(x)=[x]
This takes any integer as an input and the output is the greatest integer less than the input.
For instance
f(4.9)=4 because 4 is the greatest integer less than 4.9
f(-3.4)=-4 because -4 is the greatest integer less than -3.4
This graph is not one-to-one because more x-values can correspond to one y-value.
For instance f(3.4)=3 and f(3.9)=3
The correct options are A and E
Answer:
Step-by-step explanation:
The triangle is a right triangle.
We can use trigonometric functions to solve the problem.
tan θ = opp/adj
tan 30 = y/(4√3)
y = 4√3 tan 30
y = 4
We can set up this equation using this formula:
a = p(1 + r/n)^nt
p = starting amount.
r = interest.
n = number of times it's compounded in a year
t = years
We'd set it up like this:
a = 50(1 + ?/1)^1(12)
Because we're missing the amount of interest, it would be impossible to tell what the amount would be after 12 years.
Unit rates is the rate of a quantity in comparison to 1 i.e. unit.
Based on the given parameters, Shanya is the fastest typist
From the question, the unit rates are given as:
- James: 0.5 words per second
- Shanya = 3 words per seconds
The unit rates of Tristan and Ebony are not given.
So, we compare the rates of James and Shanya
3 words in a second is greater than 0.5 words in a second.
Hence, Shanya is the fastest typist
