equation of f(x)
point of intersection of f(x) and x axis - (-4,0)
point of intersection of f(x) and y axis - (0,4)
Equation y = x +4
g(x) = f( kx)
= kx +4
g(-2) = -2
-2k +4= -2
-2k = -2 -4
-2k = -6
k= 3
Answer:
Quadratic Formula x = [-b +- Sq root (b^2 - 4ac)] / 2a
In this example a= 2 b= -6 c= 5
x = [- - 6 +- Sq root ((-6^2) - 4 *2*5)] / 2*2
x = [6 +-sq root (36 -40)] / 4
x = 6 +- 2i / 4
x1 = 1.5 + .5i
x2 = 1.5 -.5i
Step-by-step explanation:
Answer: No.
Step-by-step explanation:
Given: A treasure chest sinks at a rate no less than 20 feet per second.
Speed = -20 feet per second.
The depth of ocean = -4200 feet
Since 1 minute = 60 seconds
Therefore 3 minutes=180 seconds
The depth D reached by treasure chest in 3 minutes is given by :-
Clearly -4200<-3600
Therefore, the treasure chest can not reach the ocean floor in less than 3 minutes.
Answer:
3600
Step-by-step explanation:
perimeter is 120ft
Goal is to get the largest area.
so you can start with a list of possible solutions:
1*119 = 119ft
2*118 = 236ft
.

.
60*60 =3600ft
61*59 = 3599ft

Answer:
x>6
Step-by-step explanation:
-3x<-18
3x>18
Therefore, x>6
