Converting to vertex form is one way of doing this
2x^2 + 12x + 19
= 2(x^2 + 6x) + 19
= 2 [ x + 3)^2 - 9] + 19
= 2(x + 3)^2 - 18 + 19
= 2(x + 3)^2 + 1
the minimum value is 1
Answer:
See below
Step-by-step explanation:
I'm not sure if there are any specific instructions on how these answers are supposed to be written, but here's my best shot:
1. U
2. XZ, VY
3. VU, WU
4. XY, ZY
5. ⊙U
6. XZ, VY (they are diameters but also intersect)
7. VY = 10 cm, WU = 5 cm
8. Diameter (of larger circle)
9. Diameter (of smaller circle)
10. Radius (of larger circle)
11. Radius (of smaller circle)
Answer:
c = - 32
Step-by-step explanation:
The common ratio r of the sequence is
r = 
= 
= - 2
To find the next term in the sequence multiply the previous term by r
a = 4 × - 2 = - 8
b = - 8 × - 2 = 16
c = 16 × - 2 = - 32
Answer:
what even is this
Step-by-step explanation:
Answer:
40% increase
Step-by-step explanation:
First, find the difference:
161-115=46
Then divide by the past price to get the percent increase:
46/115=.4=40%
