Answer:
K<-12
Step-by-step explanation:
+ For that, we need the delta negatif.
+ The delta= b^2-4ac=12^2-4(-3)(k)=144+12k<0
Then, 12k<-144 (divise both sides by 12)
we have k<-12
Or an other way:
-3x^2+12x+k=0 (divise both sides by -3)
x^2-4x-k/3=0
x^2-4x+4 -4-k/3=0
(x-2)^2=4+k/3
Now , we need 4+k/3<0, k/3<-4 or k<-12
Hope you understand.
Answer:
Step-by-step explanation:
d = √((9 -(-2))² + (5 - 2)²)
d = √(11² + 3²)
d = √130
d = 11.401754250...
d = 11.4 units
From the figure shown:
Given that k=89, then:
c=g=k=o=s=w=89
b=f=j=n=r=v=89
d=h=l=p=t=x=180-89=91
a=e=i=m=q=u=91
thus the sum of <span> s,e,q,u,o,i,a will be:
</span>s+e+q+u+o+i+a
=89+91+91+91+89+91+91
