Answer:
The value of x = 12, makes the statement 
true
Option D is correct option.
Step-by-step explanation:
What value of x makes this statement true?
We need to solve the equation to find value of x
Subtract 2x on both sides
So, the value of x is: x=12
So, The value of x = 12, makes the statement true
Option D is correct option.
If;
A = Adjacent
O = Opposite
H = Hypotenuse
Then,
Sin Ф = O/H
Cos Ф = A/H
Therefore,
(Sin Ф)/Cos Ф) = (O/H)/(A/H) = (O/H)*(H/A) = O/A
Now,
tan Ф = O/A ----
Therefore, it is true that
tan Ф = SinФ/CosФ
Answer:
R - chart
Step-by-step explanation:
Range chart (R chart) is a control chart used for processes with two or more subgroups to determine if a process is stable or not. It monitors the mean and range of a normally distributed variable simultaneously collected at regular intervals during a given time. It is used when measuring small subgroups between two and ten at regular intervals from a process. Iy is a;so used for constant subgroups.
On the negative plane field? because everything on the - side is negative.
Use the slope formula which is y2-y1/x2-x1. -1-4/5-(-2)= -5/7
