Answer:
i think the answer will be 37 people own dogs
Step-by-step explanation:
- some important information is that there are a total of 10,000 people in the town.
- if you survey 120people
- which 83 say yes to a dog
- so you have to subtract the amount of people you surveyed which was 120 people - the 83 people who said yes.
If the diameter is 3 feet, then the radius is 1.5 feet. Area of a circle = pi * radius squared or
A = pi * (1.5)²
A = pi * 2.25
A = 3.14 * 2.25
A = 7.065 ≈ 7.1
7.1 feet² is your answer.
-3x^4 + 27x^2 + 1200 = 0
factor out -3
-3(x^4 -9x^2 -400)=0
divide by -3
x^4 -9x^2 -400=0
(x^2-25) (x^+16) = 0
x^2-25=0 x^2+16=0
(x-5)(x+5)=0 x^2=-16
x=5 x=-5 x = 4i x=-4i
Answer: x=5 x=-5 x = 4i x=-4i
The awnser is :
6y^3 + 17y^2 + 22y + 15
Hope it helps
