Axis of symmetry = -b/2a
y + 3x - 6 = -3(x-2)² + 4
y + 3x - 6 = -3 ( x²-4x+4) + 4
y + 3x - 6 = -3x² + 12x -12 + 4
y + 3x - 6 = -3x² + 12x -8
y = -3x² + 12x - 3x -8 + 6
y = -3x² + 9x -2
(a=-3, b=9, c=-2)
Axis of symmetry = -b/2a = -9/2(-3) = -9 / -6 = -3 / -2 = 3/2
Hence, option A) x=3/2 is the correct answer.
Answer:
86 is a term in the sequence
Step-by-step explanation:
2; 6; 10; 14; 18;.....
T1=1*4-2=2
T2=2*4-2=6
T3=3*4-2=10
T4=4*4-2=14
T5=5*4-2=18
......................
Tn=n*4-2
n*4-2=86
n*4=88
n=88/4
n=22
86 is T22 in the sequence.
1/20 is equivalent to .05 because 5/100 is 1/20.
Hope this helps!
R = 7 d = 14 (to find the radius d ÷ 2) h = 10
(2πr²)
2 x 3.14 x (7x7)
2 x 3.14 x 49 = 307.72
(πdh)
3.14 x 14 x 10 = 439.6
Take the two answers and add.
307.72 + 439.6
Final answer = 747.32
Answer:
265x
Step-by-step explanation:
Squared mean to multiply the number times itself. So 15x times 15x.
Then we add 40x
