That’s a trapezoid. To find the area of a trapezoid, you take the 2 bases (9ft and 14ft) and add them up (23ft). Then divide the sum of the 2 bases by 2 (23/2=11.5). Then you take that and multiply it by the height (7ft). So 11.5(7)=80.5ft^2.
Formula for area of trapezoid:
a+b/2•h
a=base 1. b=base 2. h=height

What is the equation of a hyperbola with a = 9 and c = 12? Assume that the transverse axis is horizontal
Lorico [155]
The general equation of a hyperbola with a horizontal transverse axis is defined as:
x²/a² - y²/b² = 1

Solving for b², we use the formula: a² + b² = c²
b² = 12² - 9² = 63

Equation of our hyperbola will be:
x²/81 - y²/63 = 1

I NEED HELP PLEASE, THANKS! :)

Hey there! :)

Answer:

First option: As x⇒ ∞ f(x) ⇒ -∞.  As x⇒ -∞ f(x) ⇒ ∞.

Step-by-step explanation:

Rearrange the equation:

f(x) = -x³ - 2x² + 1

This is a negative cubic function. The function decreases over the interval

(-∞, ∞). Therefore:

As x⇒ ∞ f(x) ⇒ -∞.

As x⇒ -∞ f(x) ⇒ ∞.

This is the first option.
