Step-by-step explanation:
I just converted using the unit graph
29.
As , .
This can be easily verified by looking at the graph (graph of a quadratic equation).
30.
The growth of a population is not linear, it's exponential.
31.
Exponential growth > polynomial, so .
35.
The question is asking V(t) for t = 40.
36.
The point of symmetry of a quadratic equation is at its vertice:
The line is x= 3.
Answer:
63
Step-by-step explanation:
6*(-3)= -18
2+(-18)= -16
3*(-16)= -48
15- -48= 63
A squared + B squared = C squared. Collect like terms which gives you what I wrote.
Answer:
5
Step-by-step explanation:
x²-6x+y²+4y+13=0
or, x²-6x+y²+4y+9+4=0
or, x²-6x+9+y²+4y+4=0
or, (x²-2.3.x+3²)+(y²+2.2.y+2²)=0
or, (x-3)²+(y+2)²=0
Square of two positive terms is 0
x-3=0
x=3
and
y+2=0
y=-2
so,
x-y=3+2
=5
