Answer:
Its answer is 25.75×10-5.
<span>So we need to find a number that is between 8/11 and 0.85. This will be easy if we write all numbers in decimal form. 8/11=0.7272727273 and 0.85 is the interval in which we are looking for. The numbers are: A 23/33=0.69696969, B 39/66=0.590909090 C 157/198= 0.792929292 D 88/99=0.888888888. The only number in the interval is C 157/198=0.792929292.</span>
C/sinB = 8/sinC
c/sinB=8/0.64
c/sinB=12.5
c=12.5*0.34
c=4.25
8*8+4.25*4.25=a^2
64+18.06=a^2
82.06=a^2
a=sqrt(82.06
a=9.05

Answer:
vertex: (-2, 4)
Step-by-step explanation:
Use your regression calculator to find the parameters of the quadratic model.
The vertex form equation is ...
y = -3(x +2)^2 +4
so the vertex is (-2, 4).
__
The standard form equation is the expansion of the above:
y = -3x^2 -12x -8
