Answer:
The first option is the correct option
Step-by-step explanation:
From the question the slope AC is evaluated as


And the slope of line CB is mathematically evaluated as


Now for lines that are perpendicular to each other then the product of their slope should be equal to -1
So if

Then

i,e
![[\frac{b}{a+ c} ] [\frac{b}{a-c} ] = -1](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bb%7D%7Ba%2B%20c%7D%20%5D%20%5B%5Cfrac%7Bb%7D%7Ba-c%7D%20%5D%20%3D%20-1)
The perimeter = 4 * length of a semicircle of radius 5 == 4* pi * 5 = 20 pi cm
The area of one of the clear parts = 1/2 area of square - area semicircle
= 1/2 * 10^2 - 1/2 pi *5^2 = 50 - 12.5pi
So area of shaded parts = area of square - 4 (50 - 12.5pi)
= 100 - 200 + 100pi = (100pi - 100) cm^2
I do think it's A and B. :)
Answer:
1.6 =x
Step-by-step explanation:
tan theta = opposite side/ adjacent
tan 37 = x /2.1
Multiply each side 2.1
2.1 tan 37 = x/2.1 * 2.1
2.1 tan 37 = x
1.582463505 =x
To the nearest tenth
1.6 =x
Answer:
33.0220147 % reduction
Step-by-step explanation:
Take the original price and subtract the new price
14.99-10.04 = 4.95
Divide by the original price
4.95/14.99 =.330220147
Change to percent form
33.0220147 %
