Answer:

12 miles

Step-by-step explanation:

Let the amount of hours it takes Leroy to catch up to Kevin equal x. Since speed multiplied by time is distance, Leroy would have run a total of 6x miles(6*x). Kevin already had a head start of 24 minutes, which is the same as 2/5 of an hour. In 2/5 an hour, Kevin ran 2 miles as 2 is 2/5 *5. For the next x hours his distance would be a total of 5x(5*x). This means, after x hours, Kevins distance is 5x + 2. In this case, catching up to someone is the same as having the same distance value. This means we can set the two expressions equal to each other, and solve:

6x = 5x + 2

x = 2

The time it took Leroy to catch up is 2 hours, but we are looking for the distance, which is represented by 6x. We substitute in 2 to get:

6(2) = 12

This means Leroy had to run 12 miles.

If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is _.
defon

Answer: If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is <u>its conjugate 7-i5</u>.

Step-by-step explanation:

  • We know that when a complex number z=a+ib is a root of a polynomial with degree 'n' , then the conjugate of the complex number (\overline{z}=a-ib) is also a root of the same polynomial.

Given: 7+5i is a zero of a polynomial function of degree 5 with coefficients

Here, 7+5i is a complex number.

So, it conjugate (\overline{7+5i}=7-5i) is also a zero of a polynomial function.

Hence, if 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is <u>its conjugate 7-i5</u>.

valkas [14]
2/3 (simply simplify/divide them by 3)
Or
.66666 (basically repeating numbers)
Or
66.6 % (Make sure for the decimal or percentage you write a line above the 6 after the 1st number behind the decimal to show it as a repeating number!)

Identify the maximum or minimum point from the graphType your answer as an ordered pair (x,y)
Zepler [3.9K]

We have a parabola.

As it is concave down, we have one maximum and no minimum.

We can identify the maximum at point (-2, 4).

Answer: (-2,4)
