Answer:

Step-by-step explanation:

Area of shaded region = Area of quadrant - area of triangle

= (1/4)πr² - (1/2)bh

$=\frac{1}{4}*3.14*5*5-\frac{1}{2}*5*5\\\\=19.625 - 12.5\\\\= 7.125\\\\$

= 7 cm²

If alpha and beta are the zero of a quadratic polynomial p(x) find p(x) if alpha + beta=19 and alpha-beta=5

oee [108]

Answer:

p(x) = x^12 -19x +84

Step-by-step explanation:

Adding the given equations yields ...

2·alpha = 19+5

alpha = 24/2 = 12

Then beta = 19-12 = 7

The factored form of p(x) is then ...

p(x) = (x -12)(x -7)

Multiplying this out gives ...

p(x) = x^2 -19x +84

_____

Another way to get there is to realize that ...

p(x) = x^2 -(alpha+beta)x +(alpha·beta)

The constant term can be computed from the given sum and difference as ...

alpha·beta = ((alpha+beta)^2 -(alpha-beta)^2)/4 = (19^2 -5^2)/4 = 84

Then ...

p(x) = x^2 -19x +84

The question and answer choices are listed in the picture.

Given:
$L=2 \pi r( \frac{x}{360})$

Solution:
If we want to find the solution for r, we need to move the r to the left side first. So I reverse the side
$2 \pi r( \frac{x}{360})=L$

Move 2π to the right side. Because on the left side 2π acts as numerator, after it's moved to the right side, it becomes denominator.
$2 \pi r( \frac{x}{360})=L$
$r( \frac{x}{360})= \frac{L}{2 \pi }$

Move 360 to the right side. Because on the left side 360 acts as denominator, after it's moved to the right side, it becomes numerator.
$r( \frac{x}{360})= \frac{L}{2 \pi }$
$r(x)= \frac{360L}{2 \pi }$

Move x to the right side. Because on the left side x acts as numerator, after it's moved to the right side, it becomes denominator.
$r(x)= \frac{360L}{2 \pi }$
$r= \frac{360L}{2 \pi x}$

Then simplify the fraction
$r= \frac{360L}{2 \pi x}$
$r= \frac{180L}{ \pi x}$

The answer is second option
