Which of the following points are more than 5 units from the point P(−2, −2)? Select all that apply. A A (2, 1) B B (4, −1) C C

netineya [11]

The distance between any 2 points P(a,b) and Q(c,d) in the coordinate plane, is given by the formula:

 $|PQ|= \sqrt{ (a-c)^{2} + (b-d)^{2}}$

Using this formula we calculate the distances |PA|, |PB|, |PC|, |PD| and |PE| and compare to 5.

$|PA|= \sqrt{ (-2-2)^{2} + (-2-1)^{2}}= \sqrt{16+9}= \sqrt{25}=5$

$|PB|= \sqrt{ (-2-4)^{2} + (-2+1)^{2}}= \sqrt{36+1}= \sqrt{37} \approx 6$

$|PC|= \sqrt{ (-2-2)^{2} + (-2+3)^{2}}= \sqrt{16+1}= \sqrt{17}\approx4$

$|PD|= \sqrt{ (-2+6)^{2} + (-2+6)^{2}}= \sqrt{16+16}= \sqrt{32}\ \textgreater \ \sqrt{25}=5$

$|PE|= \sqrt{ (-2+5)^{2} + (-2-1)^{2}}= \sqrt{9+9}= \sqrt{16}=4$

P(a) = 2a -3; find p(a) = 15

Andrei [34K]

Since both is equal to p(a), you can set them as equal to each other:

15 = 2a - 3
18 = 2a
9 = a

Answer:

b= 70

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to exterior angle.

a+b = 140

We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal

b+b = 140

2b =140

Divide by 2

2b/2 =140/2

b= 70

The figure shows a circle within a square. Find the circumference of the circle let π = 3.14.

Andru [333]

The side of the square = 16 in

When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle.

So, the diameter of the circle is equal to 16 in => radius = 8 in

Circumference = 2πr = 2π8 = 16π = 50.24
