It looks like selections A and C are identical. (Neither is equivalent to 9^x.)

If B is supposed to be 3^(2x), it is equivalent to F and D and to the given expression.

Of course, D evaluates to 9^x, so is equivalent.

Choice E evaluates to 3^(x+2), which is not equivalent to 3^(2x).

The applicable choices appear to be

... B. 3^(2x)

... D. (3*3)^x

... F. (3^x)*(3^x)

Help ASAP lines a and b are perpendicular. The equation of like a is y=1/3x+3 what is the equation of line b

PSYCHO15rus [73]

Answer:

y = -3x - 4

Step-by-step explanation:

From the graph we see that the equation of a line is y = $\frac{1}{3}x + 3$

Note that the product of the slopes of perpendicular lines = -1.

The general equation of the line is: y = mx + c, where m is the slope.

Since the slope of this line is 1/3, the slope of its perpendicular line should be -3.

Therefore, we arrive at the slope - one point form to determine the equation of the line.

That is: (y - y₁) = m(x - x₁)

where, (x₁, y₁) is the point passing through the given line.

Here, from the graph the point (0, 4) passes through it.

So, y - (-4) = -3(x - 0)

⇒ y + 4 = -3x

⇒ y = -3x - 4 which is the required equation of the line.

Need a refresh on scientific notation? help.

Dmitrij [34]

Scientific notation can be scary but it really is simple
the exponent after the 10 is how many places you move the decimal. If it is positive you move it right, if it negative you move it left
2 x 10^2 means you move the decimal place right twice to make 200
4 x 10^-3 means you move the decimal place left three times to make .004
The question is asking you to multiply 900000 and .0000006

The graph of the function g(x) contains the point (4,1/5). What point must be on the graph of y=5g(x+1)?

stich3 [128]

<em>The point that must be on the graph of:</em>

$y=5g(x+1)$

$(3,1)$

<h2>Explanation:</h2>

In this case, we have the following function:

$g(x)$

This function contains the point:

$(4,\frac{1}{5})$

In other words:

$For \ the \ point \ (4,\frac{1}{5}) \rightarrow x=4 \ and \ y=\frac{1}{5} \\ \\ So: \\ \\ y=g(x) \ and \ g(4)=\frac{1}{5} \\ \\ \\ For \ y=5g(x+1) \\ \\ We \ know \ g(4) \ So: \\ \\ x+1=4 \ \therefore x=3 \\ \\ Then: \\ \\ y=5g(3+1) \\ \\ y=5g(4) \\ \\ y=5(\frac{1}{5}) \\ \\ y=1$

<em>So the point that must be on the graph of:</em>

$y=5g(x+1)$

$(3,1)$
