Use this equation: A=3.14159r^2
-6 and -6 because -6 + -6 = -12 , you could also have -8 and -4 because -8 + -4 = -12, or you could also have -10 and -2 because -10 + -2 = -12
Answer:
A: 300 B: Malorie
Step-by-step explanation: Katina's account starts at $200 and increases by $20 each month. Malorie starts at only $100 but increases at a rate of $50 per month. for "A", Katina is 4 months in which equals $280. so, you take Malorie's $50 rate times the 4 months and you get $200. You then add that $200 to the starting $100 to equal $300.
B: 50m>20m. Malorie's monthly rate is listed in the equation as $50. Katina's rate of $20 comes from the $20 increase in her account each month.
Answer:
Exactly two distinct zeros
Step-by-step explanation:
y = 2(x-1) (x + 4)
Plug y = 0
0 = 2(x-1) (x + 4)
0/2 = (x-1) (x + 4)
(x-1) (x + 4) = 0
(x-1) = 0 or (x + 4)= 0
x = 1 or x = - 4
Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.
