D.
729

Answer 1

Answer: This answer uses NMF, which can be found out about in my profile:

We know that the length has to equal the width and height. This means that the amount of cubes used in total has to be the cube (power of 3) of the side length.

The answer is
floor#({3}√{x}) = {3}√{x}
where x is your possible answers and the statement is true.

If we do x = 81, then we can do
{3}√{81} ≈ 4.33
floor#(4.33) ≠ 4.33
therefore the answer is not 81

x = 243:
{3}√{243} ≈ 6.24
floor#(6.24) ≠ 6.24

x = 486:
{3}√{486} ≈7.86
floor#(7.86) ≠ 7.86

x = 729:
{3}√{729} = 9
floor#(9) = 9
Because they are equal, the number of cubes used is 729.

Answer:

B) {8.71}

Step-by-step explanation:

3. l.c.m=28

28×3/7=28×b-7/4

4×3=7(b-7)

12=7b-49

12+49=7b

61=7b

61/7=7b/7

8.71=b

b=8.71.

B. y=-√x-2) +5

C. y=-√x+2) -5

D. y=-√x-5) +2

y = √(x + 5) + 2

Further explanation

Given:

The graph of $y = √(x)$ is

shifted 2 units up, and
5 units left.

Question:

Which equation represents the new graph?

The Process:

The translation is a form of transformation geometry.

Translation (or shifting): moving a graph on an analytic plane without changing its shape.

In general, given the graph of y = f(x) and v > 0, we obtain the graph of:

$\boxed{ \ y = f(x) + v \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ upward v units.
$\boxed{ \ y = f(x) - v \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ downward v units.

That's the vertical shift, nowthe horizontal one. Given the graph of y = f(x) and h > 0, we obtain the graph of:

$\boxed{ \ y = f(x + h) \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ to the left h units.
$\boxed{ \ y = f(x - h) \ }$ by shifting the graph of $\boxed{ \ y = f(x) \ }$ to the right h units.

Therefore, the combination of vertical and horizontal shifts is as follows:

$\boxed{\boxed{ \ y = f(x \pm h) \pm v \ }}$

The plus or minus sign follows the direction of the shift, i.e., up-down or left-right.

- - - - - - - - - -

Let's solve the problem.

Initially, the graph of $y = √(x)$ is shifted 2 units up.

$\boxed{y = √(x) \rightarrow is \ shifted \ 2 \ units \ up \rightarrow \boxed{ \ y = √(x) + 2 \ }}$

Followed by shifting 5 units left.

$\boxed{y = √(x) + 2 \rightarrow is \ shifted \ 5 \ units \ left \rightarrow \boxed{ \ y = √(x + 5) + 2 \ }}$

Thus, the equation that represents the new graph is $\boxed{\boxed{ \ y = √(x + 5) + 2 \ }}$

The answer is A.
