Answer: $\overline{PQ}=\overline{PR}$

Step-by-step explanation:

Tangent :- A line that touches a curve or circle at a point but if extended does not cross it at that point.

From the given picture, it can be seen that $\overline{PR}\text{ and }\overline{PQ}$ are two tangents on circle from an external point P .

We know that the length of any two tangents drawn from any external point to the circle are congruent.

Therefore, the equation for the relationship between the measures of the segments will be:-

$\Rightarrow\overline{PQ}=\overline{PR}$

Given two vectors A=2i+3j+4k,B=i-2j+3k find the magnitude and direction of sum (physics question)

Law Incorporation [45]

Answer:

$Magnitude =\sqrt{59} \\\\Direction \: of \: \overrightarrow{A + B} = \frac{3}{\sqrt {59}} , \:\frac{1}{\sqrt {59}} , \:\frac{7}{\sqrt {59}}$

Step-by-step explanation:

A=2i+3j+4k

B=i-2j+3k

Sum of the vectors:

A + B = 2i+3j+4k + i-2j+3k = 3i + j + 7k

$Magnitude =\sqrt{3^2 + 1^2+ 7^2} \\\\Magnitude =\sqrt{9+1+49} \\\\Magnitude =\sqrt{59}$

Direction of the sum of the vectors:

$\widehat{A + B} =\frac{\overrightarrow{A + B}}{Magnitude\: of \:\overrightarrow{A + B}} \\\\\widehat{A + B} =\frac{3i + j + 7k}{\sqrt {59}} \\\\\widehat{A + B} =\frac{3}{\sqrt {59}} i +\frac{1}{\sqrt {59}} j+\frac{7}{\sqrt {59}} k\\\\Direction \: of \: \overrightarrow{A + B} = \frac{3}{\sqrt {59}} , \:\frac{1}{\sqrt {59}} , \:\frac{7}{\sqrt {59}} \\\\$

Which measurement could be a volume measure? A; 25 kg B; 36 m 2 C; 44 mm D; 75 in 3 help please ..

DanielleElmas [232]

Answer:

Step-by-step explanation:

Volume can be described as the total amount of space that is in a closed surface. this amount of space is usually three dimensional. Volume is usually measured in m³ or cm³ or in³

For example, the volume of a rectangular box given the following dimension : length - 3cm

breadth - 8cm

height - 10 cm

volume = length x width x height = 8 x 3 x 10 = 240 cm³

140 degrees decreased by 65%

BaLLatris [955]

Hey there!
Here are the steps involved:

1.Change 65% into a decimal. Move the decimal two places to the left and you get 0.65.

2. Multiply 0.65 by 50.
140 x 0.65 = 91.

3. Since you are decreasing 140 by 65%, subtract 140 by 91.
140-91= 49
