Answer:
Center (7,2); Radius - Square Root of 10
Step-by-step explanation:
Equation for a Cricle:
(x−h)^2 + (y−k)^2 = r^2
Where:
h = x-coordinate of the center of the circle
k = y-coordinate of the center of the circle
r = radius of the circle
For this problem, your h = 7, k = 2, and r = square root of 10
In your head, you should be able to add 15 and 5. The answer is 20. You should also be able to work out 20 + 9. The answer is 29. The trick to doing well at these types of questions is finding the quickest and easiest method of working them out. It will come with practice :)
The decimal from the fraction is .375
Answer:
Amber should choose the one-time payment of $500. If amber chooses the 12% commission she would receive $474 which would be less than a payment of $500.
Step-by-step explanation:
Commission calculation:
(Total sales) * (Commission %)
(3,950) * (.12) = $474
She should choose the $500 one time payment.
Answer:
x = 2 or x = 1 or x = 0 or x = -1 or x = -2
Step-by-step explanation:
Solve for x:
x^5 - 5 x^3 + 4 x = 0
The left hand side factors into a product with five terms:
x (x - 2) (x - 1) (x + 1) (x + 2) = 0
Split into five equations:
x - 2 = 0 or x - 1 = 0 or x = 0 or x + 1 = 0 or x + 2 = 0
Add 2 to both sides:
x = 2 or x - 1 = 0 or x = 0 or x + 1 = 0 or x + 2 = 0
Add 1 to both sides:
x = 2 or x = 1 or x = 0 or x + 1 = 0 or x + 2 = 0
Subtract 1 from both sides:
x = 2 or x = 1 or x = 0 or x = -1 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 2 or x = 1 or x = 0 or x = -1 or x = -2
