Answer: 78.5

Step-by-step explanation:

Formula: A=pi*r^2 or Area = 3.14*radius squared (by two)

A = 3.14*10^2

A = 3.14*100

A = 314

Divide it by 4, because it's a quarter of the circle: A = 314/4

A = 78.5

Answer: 78.5

If (x + 2) is a factor of x3 – 19x – p, find the value of p. Help please

Sergio039 [100]

If $x-a$ is a factor of a polynomial $P(x)$ then, $a$ is its root.

So $-2$ is a root of $x^3-19x-p$

$(-2)^3-19\cdot(-2)-p=0\\-8+38-p=0\\p=30$

Answer:

0.8809 = 88.09% probability the ships will sail full.

Step-by-step explanation:

What is the probability the ships will sail full?

0.75 of 0.23(dollar appreciating)

0.92 of 1 - 0.23 = 0.77(dollar not appreciating). So

$p = 0.75*0.23 + 0.92*0.77 = 0.8809$

0.8809 = 88.09% probability the ships will sail full.
