Answer:

f(-1) = 3

General Formulas and Concepts;

<u>Pre-Alg</u>

Order of Operations: BPEMDAS

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 9(3)ˣ

x = -1

<u>Step 2: Solve</u>

Substitute: f(-1) = 9(3)⁻¹
Evaluate: f(-1) = 9(1/3)
Multiply: f(-1) = 9/3
Divide: f(-1) = 3

Find the equation of the line through (8,−6) which is perpendicular to the line y=x3−7.

ycow [4]

Answer:

y = (-1/3)(x + 10)

Step-by-step explanation:

The slope of the new (perpendicular) line is the negative reciprocal of the slope of the given line, which appears to be 3. Thus, the perpendicular line has the slope -1/3.

Using the slope-intercept form y = mx + b, and substituting the givens, we obtain:

y = mx + b => -6 = (-1/3)(8) + b, or

-6 = -8/3 + b. We must solve for the y-intercept, b:

Multiplying all three terms by 3 removes the fraction:

-18 = -8 + 3b. Thus, -10 = 3b, and so b must be -10/3.

The desired equation is

y = (-1/3)x - 10/3, or

y = (-1/3)(x + 10)

The replica of the Empire State Building with its antenna spire in Las Vegas is

postnew [5]

Answer: $\frac{485}{ 1,454}$

Step-by-step explanation:

For this exercuse you need to analize the information provided. You know that:

1) The height of the replica of the Empire State Building with its antenna spire in Las Vegas is 485 feet.

2) The height of the real Empire State building is 1,454 feet.

Finally, in order to find the ratio of height of the replica to the height of the real Empire State building, its necessary to divide the height of the replica of the Empire State Building by the height of the real Empire State building.

Therefore, trough this procedure you get that the ratio of height of the replica to the height of the real Empire State building is:

$ratio=\frac{heigth_{ replica}}{heigth_{real}}=\frac{485}{ 1,454}$

(This fraction cannot be reduced)
