For f(x)=ax^2+bx+c
the axis of symmetry is -b/2a
f(x)=2x^2+4x+2
a=2
b=4
-4/(2*2)=-4/4=-1
the axis of symmetry is x=-1
B
Answer:
5
Step-by-step explanation:
5÷5x and 25÷5
1 × 5
your answer is 5
Well, we know that 1 hour is 60 minutes which means 2 hours is 120.
so to find the answer we turn 40% into a decimal which would be .40
Take .40 and multiply that by 120.
.40 * 120 is 48
40% of 2 hours is 48 minutes.
Hope this helps!
Answer:
the area is 5.25 and the perimeter is 14
Step-by-step explanation:
first multiply 6cm and 1 3/4 which converts to 1.75, so 6x1.75+10.5 and to find the area of a triangle you multiply the base by the height and divide by 2 so 10.5 divided by 2 is 5.25 for the area, the perimeter is 14 because you're supposed to add all the sides and the sum is the perimeter 20 6 and 1/4 is converted to 6.25 therefore you add 6.25,6, 1.75 together to get 14
