There is an integer n such that 2n2 − 5n + 2 is prime. To prove the statement it suffices to find a value of n such that (n, 2n2

− 5n + 2) satisfies the property "2n2 − 5n + 2 is prime." Show that you can do this by entering appropriate values for n and 2n2 − 5n + 2.

Answer:

n = 0 or 3

Step-by-step explanation:

2n² - 5n + 2

2n² - 4n - n + 2

2n(n - 2) -1(n - 2)

(n - 2)(2n - 1)

Prime number is one which is divisible by itself and 1

n-2 = 1 n = 3

2n-1 = 1 n = 0

Given A(-2,3), B(m, 5) and C(-1,0). Find the possible<br>values of m if AB = 2AC.​
babymother [125]

Answer:

m = 4 or m = -8

Step-by-step explanation:

length between 2 points = √(difference of x)² + (difference of y)²

AB² = (m - (-2))² + (5 - 3)² = (m + 2)² + 4 = m² + 4m +8

AC² = ((-1) - (-2))² + (0 - 3)² = 10

AB² = 4AC²

m² + 4m +8 = 40

m² + 4m - 32 = 0

(m - 4) (m + 8) = 0

m = 4 or m = -8

Darcy harvests 8 3/4 acres of corn every 5/6 of an hour. Darcy harvests corn at a constant rate. How many acres does she harvest
Inessa05 [86]

Answer: 10 1/2, which can be simplified as 10.5

Explanation: First, set up a proportion with acres of corn to time in hours:

8 3/4 acres = x acres

5/6 hour = 1 hour

Reorder the terms:

x = (8 3/4) / (5/6)

To figure that out the math, change the mixed fraction to an improper fraction, and change the division into a multiplication:

x = (35/4) * (6/5)

Next cancel out:

x = (7/2) * (3/1)

x = 21/2

Lower that faction the the lowest denominator:

21/2 = 10½

Thus, your answer is 10½, or in other words 10.5

Hope this helps! :)
