If LR = 12 and LP = 7, find PR. Explain.

sergiy2304 [10]

Answer:

PR = 5 because LP + PR = LR according to the Segment Addition Postulate, and 7 + 5 = 12 using substitution

Step-by-step explanation:

The naming of the segments suggests that point P is between L and R, so that ...

LP + PR = LR

This corresponds to the last choice.

_____

Comments on the alternate interpretation

On the other hand, if point L is between P and R, then the segments are PL and LR. The Segment Addition Postulate would tell you that ...

PL + LR = PR

The Reflexive Property of Congruence would tell you that PL = LP. The Substitution Property would tell you LP can be substituted into this equation, making it ...

LP + LR = PR

and by the commutative property, ...

LR + LP = PR.

Multiple properties of addition and congruence are involved with this interpretation, which more or less matches the third choice. That is, the simple explanation of answer choice 3, by itself, is insufficient to explain why the length of PR should be considered to be 19, not 5.

Answer:

____________________________________

$\large{ \tt{ \star \: S \: O \: L \: U \: T \: I \: O \: N : }}$

$\large{ \boxed{ \tt{♡ \: VOLUME \: = l \: \times b \: \times h}}}$

$\longrightarrow \: 4 \frac{1}{3} \times 3 \frac{1}{3} \times 4$

$\longrightarrow \: \frac{13}{3} \times \frac{10}{3} \times 4$

$\longrightarrow \: \frac{540}{9}$

$\longrightarrow \tt \: 57 \frac{7}{9} \: ft ^{3}$

Our final answer is 57 7 / 9 ft^3 .

Write the complex number in polar form with argument between 0 and 2.

pychu [463]

Lets say that √(3+i) is the magnitude of your vector. In polar form, i represents the x component and j represents the y component of the vector. Therefore, the polar form is icosθ√(3+i) + jsinθ√(3+i)

draw a diagram :

z = r(cos θ + i sin θ), where z = complex number, r = modulus, θ = angle of rotation For the given:r = 2θ = π/6 √3 + i = 2(cos π/6 + i sin π/6)

hope thz hlpz ✿
