Answers

Answer 1

Answer:

Answer:

This would be .0051 as an ordinary number.

An airplane flies six hundred miles to the south; then, after landing and refueling, it flies due north for three hundred miles. What is the airplane's displacement? (Remember, displacement is a vector, so direction needs to be indicated in your answer).

Answers

Displacement =

   (distance between the start-point and the end-point)
in the direction of
   (direction from the start-point to the end-point).

For the entire story, the displacement is

   300 miles south .

If it's going 600 miles S, and 300 miles N, the displacement is 300 miles S

Which corresponds to the perimeter of triangle ABC?A (-5,-1)
B (-2,3)
C (6,-3)

A. 15 units
B. square root 250 units
C.15+ square root 125 units
D.125+ square root 125 units

Answers

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

A (-5 , -1)

B (-2, 3)

C (6, -3)

Perimeter = ?

Formula

$d = \sqrt{(x2 - x1)^(2) + (y2 - y1)^(2) }$

distance AB $d = \sqrt{(-2 + 5)^(2) + (3 + 1)^(2) }$

$d = \sqrt{(3)^(2) + (4)^(2) }$

$d = √((9 + (16) )$

$d = √(25)$

d = 5

Distance BC $d = \sqrt{(-3 - 3)^(2) + (6 + 2)^(2) }$

$d = \sqrt{(-6)^(2) + (8)^(2) }$

$d = √(36 + 64)$

$d = √(100)$

d = 10

Distance AC $d = \sqrt{(-3 + 1)^(2) + (6 + 5)^(2) }$

$d = \sqrt{(-2)^(2) + (11)^(2) }$

$d = √(4 + 121)$

$d = √(125)$

d = 11.2

Perimeter = 5 + 10 + 11.2

= 15 + $√(125)$

How do you find LCM of 5 and 35

Answers

Answer:

LCM is 35

Step-by-step explanation:

The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

Answer:

The answer would be 35

Step-by-step explanation:

The answer would be 35 because 35 is the least Common Multiple of 35 and 5

Can Someone please find me the value of Y? Thanks!

Answers

Since the triangles are similar the corresponding sides are in the same proportion, so:-

16/30 = 14/y

y = 30 * 14 / 16 = 26.25

What is the standard form of the equation for this circle?
(x – 4)2 + (y + 5)2 = 5.5
(x – 4)2 + (y + 5)2 = 30.25
(x + 4)2 + (y – 5)2 = 30.25
(x + 4)2 + (y + 5)2 = 11
(x + 4)2 + (y – 5)2 = 5.5
