F(x) = x^3 - 2x^2 - 6x + 12 = 0
lets try substituting some of the factors of 12:-
f(2) = 8 - 8 -12+12 = 0 So one zero is x = 2 Answer
Dividing f(x) by (x - 2) we get:-
x^2 - 6 so the other 2 zeros are sqrt6 and - sqrt6 or 2.45 and -2.45 to the nearest hundredth Answer
Answer:
90.6m
Step-by-step explanation:
Initial speed = 8m/s
Time = 4.3 s
In studying the motion of an object, we often make use of kinematic equation
s = ut + 1/2at^2
v^2 = u^2 + 2as
a = (v - u) / t
v = final velocity
u = initial velocity
s = distance or height
t = time
a = acceleration due to gravity
Given time to hit the ground as 4.3s, we calculate the height by using
s = ut + 1/2at^2
Since the stone is moving against gravity, a is negative
u = 0
s = 0(4.3) +1/2(-9.8)(4.3)^2
s = -90.6m
The height of the cliff is 90.6m
5. Area = 2 unit * 7 units = 14 squared units
6. Area = 3 units * 4 units = 12 square units
7 Area = Area of big rectangle + Area of small rectangle = 42 + 15 = 57
8. Area = 1 * 5 + 2*8 = 5 + 16 = 21 square units
Hope that helps!
Volume of a triangular prism is given by V = Al where A is the area of the triangular cross section, i.e.
, and l is the length of the triangular prism.
Here, b = 8cm, h = 9cm, and l = 5cm.
Therefore,
