Answer:
a. -14pi/9
b.-108°
Step-by-step explanation:
you have to multiply by 180 over pi
Answer:
1%
Step-by-step explanation:
Step-by-step explanation:
b^2-4b+3=0
b²-3x-b+3=0
b(b-3)-1(b-3)=0
(b-3)(b-1)=0
either
b=3 or b=1
.
2n^2 + 7 = -4n + 5
2n²+4n+7-5=0
2n²+4n+2=0
2(n²+2n+1)=0
(n+1)²=0/2
:.n=-1
.
x - 3x^2 = 5+ 2x - x^2
0=5+ 2x - x^2-x +3x^2
0=5+x+2x²
2x²+x+5=0
comparing above equation with ax²+bx +c we get
a=2
b=1
c=5
x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1
={-1±√-39}/2
Answer:
Option 3:
Step-by-step explanation:
See the attached figure.
We will make a table for each function of the options, then compare each one of them with the given table.
So, we can deduce that the function of option 3:
is the exponential equations could be represented by the table.
Note both of the given table and
has Horizontal Asymptote y =2
Which mean as x→-∞ ⇒ y→2
