Solve the problem.If a lawn sprinkler sprays 15 feet in every direction, what is the area of the yard that gets watered?
Answers
The area of yard gets watered is 707.142 ft²
What is area?
The portion between any closed figure, and the extent of region of any plane is area.
Given that sprinkler sprays 15 feet in every direction
so it will form a circle with radius of 15ft
and area of circle is πr²
where r is radius of circle
value of π is 22/7
area = π x (15)²
area = 707.142 ft²
Hence area of sprinkled region is 707.142 ft²

A=πR²=3.141592...*15²=706,8583470...( ft²)

(a^2 + 4)(a^2 - 2)=0
we then get two answers from the brackets
a^2=-4
a= sqrt(-4) or 2j
and the second bracket gives us a^2=2
a= sqrt(2)
11. First expand the brackets.
Ax^3 + Bx^2 - x^2 + Bx +Cx + D
then equate the coefficients, this basically means put all the x^3, x^2 etc values together.
so Ax^3=3x^3 so we know that A=3Then put the x^2 together, so Bx^2-x^2=-x^2 and rearranging this gives B=0
Next we do Bx+Cx = 2x and we know that B is 0 so we can get rid of it and know that C = 2.
finally we can see that D = -7

What is the equation of the inverse function N(a)?
Answers
A(n) = 4n -25
and we wish to get the inverse function N(a)
We let
A(n) = a
n = N(a)
Plugging in the values
a = 4 N(a) - 25
Arranging the equation:
4 N(a) = a + 25
N(a) = (a + 25) /4
The answer is
N(a) = (a + 25) /4
