Answer:
3
+ 4
Step-by-step explanation:
If u = < x₁, y₁ > and v = <x₂ , y₂ > , then
u • v = x₁x₂ + y₁y₂
Given
u = < , - 1 > and v = < 3, - 4 >, then
u • v = 3 + (- 1)(- 4) = 3 + 4
Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2
approximately
Answer:
16.81
Step-by-step explanation:
P = 4a.
then the length of a side is 16.4 /4 = 4.1.
A = a * a = 4.1 * 4.1 = 16.81
