What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.

kari74 [83]

Answer:

We conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.

Step-by-step explanation:

Given

L(3,4)

M(1,-2)

Determining the length of LM

(x₁, y₁) = (3, 4)

(x₂, y₂) = (1, -2)

The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)

$=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}$

$=\sqrt{2^2+6^2}$

$=\sqrt{4+36}$

$=\sqrt{40}$

$=\sqrt{4\times 10}$

$=\sqrt{2^2\times \:10}$

$=2\sqrt{10}$

$=6.3$

Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.

Coach kunal stacks all of the tennis balls in a square pyramid. The number of tennis balls, P(n), in n layers of the square pyra

Zolol [24]

Answer:

D. 9

Step-by-step explanation:

We are told in the question that: The number of tennis balls represented by P(n), in n layers of the square pyramid is given as

P(n) = P(n - 1) + n²

Let's take the first layer

n = 1

P(1) = P(1 - 1) + 1²

P(1) = 1 tennis ball.

It is important to note that the first layers we have one tennis ball.

Let's take the second layer

n = 2

P(2) = P(2 - 1) + 2²

P(2) = P(1) + 2²

Note that: P(1) above = 1

P(2) = 1 + 2²

P(2) = 5 tennis balls

It is important to note that the second layer we have five tennis balls

Let's take the third layer

n = 3

P(3) = P(3 - 1) + 3²

P(3) = P(2) + 3²

Note that: P(2) above = 5

P(3) = 5 + 3²

P(3) = 14 tennis balls

It is important to note that the second layer we have fourteen tennis balls

Let's take the fourth layer

n = 4

P(4) = P(4 - 1) + 4²

P(3) = P(4 - 1) + 4²

P(3) = P(3) + 4²

Note that: P(3) above = 14

P(3) = 14 + 4²

P(3) = 30 tennis balls

It is important to note that the fourth layer we have thirty tennis balls

Hence, the number of tennis balls from the first four layers will be: 1, 5, 14, 30,

So, the number of tennis balls that Coach Kunal could not have is 9.

PLEASE PLEASE PLEASE HELP ME WITH THIS MATH

Rasek [7]

(x,y)=(x1+k(x2-x1),y1+k(y2-y1))
k is determined by writing the numerator over the sum of the numerator and the denominator of the original ratio.
k=3/(3+7)=3/10.
Point A is located at (5, 10) and point B is located at (20, 25).
(x,y)=(5+(3/10)*(20-5),10+(3/10)*(25-10))
(x,y)= (9.5,14.5)
The answer would be
(9 1/2, 14 1/2)
