Our solar system is unique in the sense that no other solar systems with planets like ours are known. the sun is a star but there are many stars in the universe. our sun is the closet one in earth. and its the only one in our solar system.
Answer:
1mn
Step-by-step explanation:
combine like terms
-8mn+9mn=1mn
Answer:
-1, 4+i, 4-i
Step-by-step explanation:
x^4- 6x^3 + 2x^2 + 26x + 17
Using the rational root theorem
we see if 1, -1, -17 or 17 are roots
Check and see if 1 is a root
1^4- 6(1^3) + 2(1^2) + 26(1) + 17=0
1-6+2+26+17 does not equal 0 1 is not a root
-1
1^4- 6(-1^3) + 2(1^2) + 26(-1) + 17=0
1 +6 +2 -26+17 = 0
-1 is a root
Factor out (x+1)
(x+1) ( x^3-7x^2+9x+17)
Using the rational root theorem again on x^3-7x^2+9x+17
Checking -1
-1 -7 -9 +17=0
-1 is a root
(x+1) (x+1) (x^2-8x+17)
Using the quadratic on the last
8 ±sqrt(8^2 - 4(1)17)
--------------------------------
2
gives imaginary roots
4±i
The answer is: b. 5%
You multiply 100 x 60 to get 6000
You then get the radius by doing A = π*r^2 = πd^2/4 which is 314.159 (rounded).
Divide 314.159 and 6000 to get 0.05235 or 5%.
A new SUV would cost $24,000 because 25% is 1/4 , so $6,000 times 4 =$24,000
