2x^2 - 5x + 12 = 0
Factoring out the leading coefficient:
2(x^2 - 5/2 x) + 12 = 0
Completing the square:
2[(x - 5/4)^2 - 25/16] + 12 = 0
2(x - 5/4)^2 - 25/8 + 12 = 0
2(x - 5/4)^2 + 71/8 = 0
q = 71/8
B, because 10+40+24 equals 74
Answer:
351.68
Step-by-step explanation:
v=
r^2h
v= 3.14(4)^2(7)
v= 3.14(16)7
v= 3.14 times 112
v=351.68
hope this helps
The total price with sales tax is $ 246.1
<h3><u>Solution:</u></h3>
Cost of cellphone = $ 210
Cost of battery charger = $ 15
Cost of batteries = $ 5
So total cost can be calculated by adding cost of cellphone and Cost of battery charger and Cost of batteries
Total cost = 210 + 15 + 5 = $ 230
Given that sales tax is 7%
sales tax = 7% of total cost
sales tax = 7 % of 230

Total cost including sales tax = 230 + 16.1 = $ 246.1
Thus the total price with sales tax is $ 246.1
Ok so remember that a circle is 360 degrees and a line is 180 degrees
so
IKJ
ok so we see that we have a triangle
to find the internal angles (which add to 180)
we do, opposite angles are equal
JIK=59
also CJI+KJI=180 so 132+KJI=180, KJI=48
so
59+48+IKJ=180
73=IKJ
HIB
we can assume that AB is paralell to CD
so therefor IJK=HIB=48 (from previous question)
EIJ is adding to EIH to get 180
EIJ+59=180
EIJ=121
AIK=AIJ+JIK
JIK=59
AIJ=HIB=48
AIK=59+48=107
IKJ=73
HIB=48
EIJ=121
AIK=107
