Answer:
The answer is 0
Step-by-step explanation:
m(x)=2x3- 3x+12
m(-2)=6-3(-2)+12
=6-6
=0
Answer:
82
Step-by-step explanation:
Angle J is 118, M is 90, and L is 70.
C(a,b), because the x-coordinate( first coordinate) is a (seeing as it is situated directly above point B, which also has an x-coordinate of a) and the y-coordinate ( second coordinate) is b (seeing as it is situated on the same horizontal level as point D, which also has a y-coordinate of b)
the length of AC can be calculated with the theorem of Pythagoras:
length AB = a - 0 = a
length BC = b - 0 = b
seeing as the length of AC is the longest, it can be calculated by the following formula:
It is called "Pythagoras' Theorem" and can be written in one short equation:
a^2 + b^2 = c^2 (^ means to the power of by the way)
in this case, A and B are lengths AB and BC, so lenght AC can be calculated as the following:
a^2 + b^2 = (length AC)^2
length AC = √(a^2 + b^2)
Extra information: Seeing as the shape of the drawn lines is a rectangle, lines AC and BD have to be the same length, so BD is also √(a^2 + b^2). But that is also stated in the assignment!
Answer:
Fy=14.8N
Step-by-step explanation:
the dot product between and
is given by:
W=
this gives the equation :
26= (4.00)(-12.0)+(5.00)Fy
26= -48+(5.00)Fy
adding 48 to both sides of the equation:
74= (5.00)Fy
dividing by 5, we get
Fy=74/5.00=14.8
