Find the distance between the points (-1,-9) and (1,-4)

Snezhnost [94]

The distance between the two points is 5.4

Explanation:

The points are (-1,-9) and (1,-4)

The distance between the two points can be determined using the formula

$d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}$

Substituting the values in the formula, we get,

$d=\sqrt{(1+1)^{2}+(-4+9)^{2}}$

Adding the values,

$d=\sqrt{2^{2}+5^{2}}$

Squaring the terms, we get,

$d=\sqrt{4+25}$

Simplifying, we have,

$d=\sqrt{29}=5.4$

Thus, the distance between the two points is 5.4

Express √12+√27 in the form n√3, where n is an integer.

Answer:

5sqroot3

Step-by-step explanation:

see image.

An integer is just a whole positive or negative (positive in this case) number that's not a fraction or decimal or mixed number. In the answer that is the 5.

To simplify a radical, look for a factor that is a perfect square. Radicals and multiplying are very friendly to each other and you can separate the "radicand" (the inside number) into factors inside the radical also into separate radicals to simplify. See image

Use the Law of Sines to find the missing angle of the triangle. Find m<b to the nearest tenth.

defon

1. By the Law of Sines, you have:

SinA/a=SinB/b=SinC/c

2. You don't need the fraction SinC/c, so you can eliminate it. Then:

SinA/a=SinB/b

A=40°
a=19
B=m∠b
b=13

3. When you substitute this values into SinA/a=SinB/b, you obtain:

SinA/a=SinB/b
Sin(40°)/19=SinB/13
SinB=13xSin(40°)/19
m∠b=SinB^-1(13xSin(40°)/19)
m∠b=26.1°

Therefore, the answer is: 26.1 degrees.
