Answer:
Step-by-step explanation:
Answer:
Solution:- In the given figure
Side of square= 10 cm
area of square = side x side m= 10 x 10 = 100 sq cm
Now , diameter of semi circle AOD = 2r = 10cm
⇒ radius of semi circle AOD = 5 cm
∴ area of AOD =
similarly Area of semicircle BOC =
Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]
=
Total area of white portion in the given figure=
∴Area of Shaded portion = area of square - area of total white portion
=
So the area of shaded portion is
Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)
So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm
Step-by-step explanation:
F(0)=0
f(-1) is undefined, so no negatives
f(4)=4
2nd graph
Step-by-step explanation:
We have y = sin(ax + b).
=> dy/dx = a * cos(ax + b)
=> d²y/dx² = a[a * -sin(ax + b)] = a² - a * sin(ax + b).
Therefore d²y/dx² = a² - ay,
d²y/dx² - a² + ay = 0.
