Answer:

5

Step-by-step explanation:

Segments are named by their endpoints. Therefore, segment PQ will have endpoints P and Q. The length of the segment is equal to the distance between these points.

To find the distance between P and Q given their coordinates, use the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Let:

P(-2, 7)\implies (x_1, y_1),\\Q(1, 3)\implies (x_2, y_2)

The distance between these points is equal to:

d=\sqrt{(1-(-2))^2+(3-7)^2},\\d=\sqrt{3^2+(-4)^2},\\d=\sqrt{9+16},\\d=\sqrt{25},\\d=\boxed{5}

Answer:

5

Step-by-step explanation:

This problem gives one the following points on a line: (P(-2,7)), and (Q(1,3)). The problem asks one to find the distance between the two points. The formula to find the distance between two points on a coordinate point is the following,

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Substitute the given values in and solve for the distance;

D=\sqrt{(-2)-(1))^2+((7)-(3))^2}

Simplify,

D=\sqrt{(-2)-(1))^2+((7)-(3))^2}\\\\D=\sqrt{(-3)^2+(4)^2}\\\\D=\sqrt{9+16}\\\\D=\sqrt{25}\\\\D = 5

Find the number of positive integers n is less than or equal to 1000 such that 15n is a perfect square.
boyakko [2]

Answer:

8 positive integers.

Step-by-step explanation:

One value of n would be 15 because 225 = 15^2.

Other values  are 225 * n where 15n  <= 1000 and n is a perfect square.

So n = 4 gives us 225* 4 = 900 which is a perfect square and 15*4 = 60.

n = 9  gives us 225 * 9 which is a perfect square and 15*9 = 135.

n = 16 gives us 225*16  and 15*16 = 240 , so OK.

n = 25   gives a perfect square and  and 15*25 = 375 - so OK.

n = 36 gives a perfect square and 15*36 = 540 - so OK.

n = 49 gives a perfect square and  15*49 = 735 - so OK.

n = 64 gives a perfect square and 15*64 = 960 - so ok.

n = 81 gives a perfect square and 15 * 81 = 1215  so NOT ok.

Mr.gilliam is 3 years younger than his wife.the sum of their ages is 95.how old is mr.gilliam
Usimov [2.4K]
X = the age of Mr. Gilliam
His wife is 3 years older, so the age of Mr. Gilliam's wife = x+3
The sum of their ages is 95.

x+x+3=95 \\&#10;2x+3=95 \\&#10;2x=95-3 \\&#10;2x=92 \\&#10;x=46

Mr. Gilliam is 46 years old.
