Answer:

Step-by-step explanation:

f(x) = x^2 - x^3

Let x=-2

f(-2) = (-2)^2 - (-2)^3

= 4 - (-8)

= 4+8

= 12

Answer:

f(-2)=12

Step-by-step explanation:

We are given:

f(x)=x^2 - x^3

We are told to find f(-2). We need to find f(x) when x is equal to -2. Therefore, we can substitute -2 in for each x.

f(-2)= (-2)^2 - (-2)^3

Evaluate the exponent -2^2 .

-2^2= -2 * -2= 4

f(-2)= 4- (-2)^3

Evaluate the exponent -2^3

-2^3= -2* -2*-2= -8

f(-2)= 4- -8

f(-2)= 4+8

f(-2) =12

f(-2) is equal to 12, therefore D is correct.

Let log_(b)A=3; log_(b)C=2; log_(b)D=5 what is the value of log_(b)((A^(5)C^(2))/(D^(6)))

Colt1911 [192]

Answer:

-11

Step-by-step explanation:

Given

$\log_bA=3\\ \\\log_bC=2\\ \\\log_bD=5$

Use properties:

$\log_b(A\cdot C)=\log_bA+\log_bC\\ \\\log_b\dfrac{A}{C}=\log_bA-\log_bC\\ \\\log_bA^k=k\log_bA$

Thus,

$\log_b\dfrac{A^5\cdot C^2}{D^6}\\ \\=\log_b(A^5\cdot C^2)-\log_bD^6\\ \\=\log_bA^5+\log_bC^2-\log_bD^6\\ \\=5\log_bA+2\log_bC-6\log_bD\\ \\=5\cdot 3+2\cdot 2-6\cdot 5\\ \\=15+4-30\\ \\=-11$

How do you do trigonometric Ratios<br>

iren2701 [21]

To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.

Where is Point A located on the coordinate grid?

Leya [2.2K]

Answer:

The answer is Quadrant I.

Step-by-step explanation:

Start from the upper left square to the right and go to the bottom left square after you move from there.

Quadrant I is like Quadrant 1. Quadrant II is like Quadrant 2 and so forth. So if each Quadrant is the square with the lines dividing it, your answer is Quadrant I.
