What is the integral of a square root? Please explain.
IrinaK [193]
If y = xⁿ

∫y dx =  xⁿ⁺¹ / (n + 1)  +  C    Provided n ≠ -1.

y = √x

y = x^(0.5)

∫y dx  =  x^(0.5+1) / (0.5 + 1) =   x^(1.5)  / 1.5 = x^(1.5)  / (3/2)

∫y dx = (2/3) x^(1.5)  + C.

∫y dx = (2/3) x^(3/2)  + C.

∫y dx = (2/3)√x³  + C

Please help! Will mark Brainiest!
DochEvi [55]

Answer:

27.93 square yard

Step-by-step explanation:

For semicircle:

Radius (r) = 7 yards

For Triangle:

b = 2r = 2*7 = 14 yd

h = 7 yard

Area of shaded region = Area of semicircle - Area of triangle

= \frac{1}{2}  \times \pi {r}^{2}  -  \frac{1}{2}  \times b \times h \\  \\  =  \frac{1}{2}  \times 3.14 \times  {7}^{2}  -  \frac{1}{2}  \times 14\times 7 \\  \\  = \frac{1}{2}  \times 3.14 \times  49  -  \frac{1}{2}  \times 98\\  \\  = 3.14 \times 24.5 - 49 \\  \\  = 76.93 - 49  \\  \\  = 27.93 \:  {yd}^{2}  \\
