Select the correct answer. You reflect triangle PQR, with vertices P(-2, -4), Q(-3, -1), and R(-4, -4), across the y-axis to get

triangle P′Q′R′. What are the coordinates of triangle P′Q′R′?

Since we have reflected only across the y-axis we know the x-values stay the same (but since they are changing quadrants will become positive) and the same goes for the y-values. Only the negative/positive area will change. Lets get to work:

<em>P(-2, -4) will become P'(2, -4)</em>

<em>Q(-3, -1) will become Q'(3, -1)</em>

<em>R(-4, -4) will become R'(4, -4)</em>

After doing this for a while you will be able to find the reflected coordinates without any trouble or graph.

<u>Key point</u><u>: Values stay the same</u>

Is the statement (3^5)^4 equal to (3^4)^5 ? explain the reasoning, DUE TOMORROW
Shkiper50 [21]

Note that both 5 and 4 are exponents, and their product is 5*4=20, or 4*5=20. Thus,

(3^5)^4 is equal to (3^4)^5

Review:

(a to the power b)to the power c = a to the power bc.

Thus, (3 to the power 5)^4 = 3^20; the same is true if you reverse the positions of the 5 and the 4.

I need help, help me plz !!!!! Match the verbal expression (term) with its algebraic expression (definition). Match Term Definit
Talja [164]

Answer:

Four less than an unknown value E) y-4

Quotient of a variable and four B) \frac{z}{4}

Some number to the power of four A) a^4

Four times an unknown value D) 4x

Four more than some number C) b+4

Step-by-step explanation:

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling y the unknown value, it means we have to write

y-4

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling z the unknown variabl, it means we have to write

\frac{z}{4}

- Some number to the power of four --> this means that we have to write the power of a number, in the form a^m, where m in this case is equal to 4. Calling a the unknown number, it means we have to write

a^4

- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling x our unknown values, we have to write

4x

- Four more than some number --> this means we have to add 4 to an unknown number. Calling b the unknown number, it means we have to write

b+4

Consider a steel ball floating on the surface of mercury in a half-filled container. What happens when the rest of the container
Helen [10]

Answer

The steel ball will be caught up in between the mercury and water medium.

Step-by-step explanation:

  • Mercury with a density of 13546 kg/m^3
  • water with a density of 1000 kg/m^3
  • Steel with a density of 8050 kg/m^3

From the factual density of both substances given above ,it shows that mercury is more heavier than water. In that case mercury will be at the lower layer when mixed with water.

The steel ball will be caught in between both mixtures as the density of  steel is 8050 kg/m^3.Which  is more than Water but less than Mercury.

Mary stated that 2.01 x 10⁶ is less than 4.8 x 10⁴ because 2.01 is less than 4.8. what was mary's mistake ?
PIT_PIT [208]

Answer:

Mary's mistake was that she didn't take into account of the power that 10 is raised to; since 2.01 is multiplied by 10 to the 6, it makes 2.01 bigger. You can also expand the number to check:

2 010 000 vs. 4800
