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.

Response:

n = 0 or 3

Detailed explanation:

2n² - 5n + 2

2n² - 4n - n + 2

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

(n - 2)(2n - 1)

A prime number is defined as one that can only be divided by itself and 1

Setting n-2 = 1 gives n = 3

Setting 2n-1 = 1 gives n = 0

243.875 to nearest tenth, hundredth, ten, and hundred
Inessa [3926]
When rounding 243.875: to the nearest tenth, it becomes 243.9; to the nearest hundredth, it is 243.88; to the nearest ten, it rounds down to 240; and to the nearest hundred, it rounds down to 200. The general rule in rounding states that if the decimal is less than 5, the number remains the same; if it is 5 or more, you round up.

−7x−50≤−1 AND−6x+70>−2
PIT_PIT [3949]

Answer:

-7\geq x and [-7,12) expressed in interval notation.

Step-by-step explanation:

A compound inequality -7x-50\leq -1\text{ and }-6x+70>-2 has been provided. Our task is to determine the solution for this inequality.

Initially, we will address each inequality independently, followed by merging the findings by combining the overlapping intervals.

-7x-50\leq -1

-7x-50+50\leq -1+50

-7x\leq 49

By dividing with a negative number, it is necessary to reverse the inequality sign:

\frac{-7x}{-7}\geq \frac{49}{-7}

x\geq -7

-6x+70>-2

-6x+70-70>-2-70

-6x>-72

Again, dividing by a negative requires flipping the inequality sign:

\frac{-6x}{-6}

x

In combining both intervals, we will arrive at:

-7\geq x

Thus, the solution for the inequality provided is -7\geq x and [-7,12) in interval notation.

David is performing the following construction. Based on the markings that are present, what construction is he performing?
Svet_ta [4341]

Answer:

He is dividing the angle BAC into two equal parts.

Step-by-step explanation:

Initially, he places the compass at point A and draws two small arcs intersecting points D and E. Next, setting the compass at D and then at E, he draws two arcs that intersect between the line segments AB and AC.

The bisecting line is drawn from point A through the intersection of these arcs.
