This is the concept of quadratic equations, solving the equation 2x^2-12x+20=0 using the formula we get:
x=[-b+/-sqrt(b^2-4ac)]/(2a)
from our equation, a=2,b=-12 and c=20
x=[-(-12+/-sqrt((-12)^2-4*2*20)]/(2*2)
x=[12+/-sqrt(144-160]/4
x=[12+/-sqrt(-16)]/4
x=[12+/-4i]/4
x=[3+\-i]
the answer is A] 3+/-i
Answer:
(-2,-1)
Step-by-step explanation:
Finding the x coordinate:
(-5) + 1 = (-4)
-4 / 2 = -2
Finding the y coordinate:
(-3) + 1 = (-2)
(-2) / 2 = -1
Answer:
The total area (including the area of the circle) would be 16 × 16 = 256 square centimetres.
The area of the circle would be (taking the value of pi as 3.14) is 200.96 square centimetres
The area of the shaded region would be 256 - 200. 96 = 55.04 square centimetres
If the car is traveling at 50meters per second then you need to multiply 50 by 60 to get how many meters a minute then multiply that number by 60 to get meters per hour then take that number and divide it by 1000 to get kilometers per hour.
Answer:360 kilometers in 2 hours and the car is going 180 kilometers per hour
Answer:
3/5
Step-by-step explanation: so far he has rolled 6/10 giving him a 6/10 probability, simplify that by 2 and you get 3/5.
