Answer:

O'(-3,-3) M'(-2,4) G'(-1-3)

Step-by-step explanation:

Rule: rotation of (x,y) counterclockwise around the origin gives (-y,x)

Thus

O(-3,3) will be O'(-3,-3)

M(4,2) will be M'(-2,4)

G(-3,1) will be G'(-1,-3)

Therefore O'(-3,-3),M'(-2,4) and G'(-1,-3) would be the answer.

The table shows the concentration of a reactant in the reaction mixture over a period of time.
saveliy_v [14]
<h3>Option C</h3><h3>The average rate of the reaction over the entire course of the reaction is: 2.0 \times 10^{-3}</h3>

<em><u>Solution:</u></em>

Average rate is the ratio of concentration change to the time taken for the change

Average\ rate = \frac{ \triangle c }{\triangle t }

The concentration of the reactants changes 1.8 M to 0.6 M

here, the time interval given is 0 to 580 sec

Therefore,

Average\ rate = \frac{1.8-0.6}{580} \\\\Average\ rate = \frac{1.2}{580} \\\\Average\ rate \approx 2.0 \times 10^{-3}

Thus option C is correct

Which of the following statements is always true? a. Workers being paid on commission make less money than if they are salaried.
cricket20 [7]

Answer:

Step-by-step explanation:

The only answer that makes any sense is B. A commission works on the premise that the more you sell, the more money you take home.

Suppose a car salesman working at a GM dealership is working on a salary of 10% of the selling price. (A bit high).

Suppose on one month he sells 10 trucks, each one selling for 40000 dollars.

1 truck brings in 40000*10/100 = 4000 for the salesman.

10 trucks bring in 10*4000 = 40000 dollars.

The next month he only sells 8 Trucks. His commission is

40000 *  10/100 = 4000 per truck

8 trucks * 4000 = 32000 total for that month. A little less but it's quite a bit for a month's work all the same.

During geometry class, students are told that ΔTSR ≅ ΔUSV. Marcus states that ΔTSR is mapped to ΔUSV by performing a rotation ab
Paha777 [63]

Answer: Both students are correct.

Explanation:

In rotation a shape is rotated about a fixed point and it does not affect its measurements. it only changes its position.

Now, When Marcus rotated the \triangle TSR  about point S then this process did not affect its shape and size this is why he got the \triangle USV which is congruent to the \triangle TSR.

In reflection, when a shape reflected across a line then its all points get reflected across this line. But it also does not affect the measurement of the shape.

So, when Sam mapped \triangle USV by the reflection of \triangle TSR then the measurement of the \triangle USV did not change. And, he also got the congruent triangle.

Thus, we can say that, Both Marcus and Sam are right.
