10. The perimeter of a regular nonagon is 162 inches. The apothem is 97.8 inches. Find the area.

Katen [24]

Answer:

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

Geometrically speaking, the area of a regular polygon is determined by following area formula:

$A = \frac{p\cdot a}{2}$ (1)

Where:

$A$ - Area of the regular polygon, in square inches.

$p$ - Perimeter, in inches.

$a$ - Apothem, in inches.

If we know that $p = 162\,in$ and $a = 97.8\,in$ , then the area of the regular nonagon is:

$A = 7921.8\,in^{2}$

The area of the regular nonagon is 7921.8 square inches.

1.) IF f(x)=3x-5 and g(x)=x^2, find (fxg)(3)

kodGreya [7K]

Please use * to denote mult. here, not "x." "x" is your variable and cannnot also be a symbol for mult.

f(x)g(x) = 3x^3 - 5x^2.

Now let x = 3:

(f*g)(3) = 3(3)^3 - 5(3)^2 = 81-45 = 36 (answer)

A shuttle launch depends on three key devices that may fail independently of each other with probabilities 0.01, 0.02, and 0.02,

worty [1.4K]

Answer:

$0.950796$

Step-by-step explanation:

Given that a shuttle launch depends on three key devices that may fail independently of each other with probabilities 0.01, 0.02, and 0.02, respectively.

Required probability = the probability for the shuttle to be launched on time

= Probability that all three do not fail

Since each key device is independent of the other

we have

prob that all three do not fail = $(1-0.01)(1-0.02)(1-0.02)\\=0.99*0.98*0.98\\=0.950796$
