Answer:
<u>It takes them 30/11 hours to paint them together.</u>
Step-by-step explanation:
This is known as a work problem (rate * time = work). We are given the individual times for Tom and Huck (6 hours and 5 hours respectively). However, we are not given the rates at which they can paint the fence. Since we know that the total work that they both do individually is 1 (there is 1 job to do), we can calculate the rates at which Tom and Huck paint the fence on their own:
We can isolate R{t} and R{h} to find the rates at which Tom and Huck work:
Now, we can calculate the time it takes for Tom and Huck to work together using the same formula (the combined rate is just the sum of Tom and Huck's individual rates):
Therefore, the time it takes them to paint the fence together is <u>30/11 Hours</u>
Answer:
x-2i
Step-by-step explanation:
Complex roots come in pairs, called complex conjugates
If you have a root a+bi, the other root is a-bi
Since you have one root x+2i, the other root is x-2i
The set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.
<h3>When does a relation represents a function?</h3>
A set, or a relation, represents a function when <u>each value of x is mapped to only one value of y</u>.
In this problem, we have that option A represents a function, as:
- In option B, x = 2 and x = -2 are mapped to two values.
- In option C, x = 4 is mapped to four values.
- In option D, both x = 1 and x = 2 are mapped to two values.
Hence the set of points that represents a function is given by:
A {(2, 1), (7, 9), (3, 12), (4, 10)}.
