Which of the following choices simplified the expression:

forsale [732]

<h2>Hello!</h2>

The answer is:

The correct option is the second option:

$\frac{5}{2},\frac{-1}{2}$

<h2>Why?</h2>

We are given the following expression:

$\frac{2+-\sqrt{9}}{2}$

Now, solving we have:

First solution:

$\frac{2+\sqrt{9}}{2}=\frac{2+3}{3}=\frac{5}{2}$

Second solution:

$\frac{2-\sqrt{9}}{2}=\frac{2-3}{3}=\frac{-1}{2}$

Hence, we have that the correct option is the second option:

$\frac{5}{2},\frac{-1}{2}$

Have a nice day!

$\frac{dw}{dt} = \frac{dx}{dt} \times \frac{dw}{dx} + \frac{dy}{dt} \times \frac{dw}{dy} + \frac{dz}{dt} \times \frac{dw}{dz} \\ \frac{dw}{dt} = 3t ^{2} \times {e}^{ \frac{y}{z} } + - t \times \frac{x {e}^{ \frac{y}{z} } }{z} + 4 \times - \frac{xy {e}^{ \frac{y}{z} } }{ {z}^{2} } \\ \frac{dw}{dt} = \frac{ {e}^{ \frac{y}{z} } (3 {t}^{2} {z}^{2} - tzx - 4xy)}{ {z}^{2} }$

Which sequence of transformations produces R'S'T' from RST? On a coordinate plane, triangle R S T has points (0, 0), (negative 2

arsen [322]

Answer:

Step-by-step explanation:

Given is a triangle RST and another triangle R'S'T' tranformed from RST

Vertices of RST are (0, 0), (negative 2, 3), (negative 3, 1).

Vertices of R'S'T' are (2, 0), (0, negative 3), (negative 1, negative 1).

Comparing the corresponding vertices we find that x coordinate increased by 2 while y coordinate got the different sign.

This indicates that there is both reflection and transformation horizontally to the right by 2 units

So first shifted right by 2 units so that vertices became

(2,0) (0,3) (-1,1)

Now reflected on the line y=0 i.e. x axis

New vertices are

(2,0) (0,-3) (-1,-1)
