The formula of the distance between two points:

A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\|AB|=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}

We have:

A(-3;-4);\ B(-8;\ 1)

substitute:

|AB|=\sqrt{(-8-(-3))^2+(1-(-4))^2}=\sqrt{(-8+3)^2+(1+4)^2}\\\\=\sqrt{(-5)^2+5^2}=\sqrt{25+25}=\sqrt{25\cdot2}=\sqrt{25}\cdot\sqrt2\\\\=\boxed{5\sqrt2\approx7.07}

Answer: B. 7.07

Given<br> BAI BD<br> mZCBD = 40 +52<br> m ABC = 82 - 10°<br> Find mZCBD:<br> B<br> D
sergij07 [2.7K]

Answer:

m∠CBD=68°

Step-by-step explanation:

BA is perpendicular to BD, meaning they form a right angle (90°)

This means m∠CBD + m∠ABC=90, or they are supplementary.

We have expressions given for these angles, so

4x+52+8x-10=90

12x+42=90

12x=48

x=4

Knowing x=4, we can substitute back into our expression for m∠CBD because that's what we're looking for.

4(4)+52=68

m∠CBD is 68°.

mel-nik [20]

Answer:

f(x)=3x−1

      2

Step-by-step explanation:

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:
