Answer:
n = 9/4 = 2.250
Step-by-step explanation:
Rearrange: 4*n-(9)=0
Solve: 4n-9 = 0
4n = 9
n = 9/4 = 2.250
answer: n = 9/4 = 2.250
A
Step-by-step explanation:
you can notice that at step 2 9 is added on both sides that is the addition property of equality
Answer:
2 yards
Step-by-step explanation:
10 divided by 5 is 2
We can use tan(x) = sin(x)/cos(x). Plug in numbers to get:
tan(x+pi/2) = sin(x+pi/2)/cos(x+pi/2)
Here, you can use the sin and cos addition identity:
tan(x+pi/2) = (sin(x)cos(pi/2)+cos(x)sin(pi/2))/(cos(x)cos(pi/2)+sin(x)sin(pi/2))
If you simplify this, you get:
0+cos(x)/0-sin(x)
Which is the definition of cot(x). But, we can't forget about the '-' sign, so, the answer is -cot(x)
Division is the inverse of multiplication; therefore it depends on knowing the multiplication table.
The problem of division is to find what number times the Divisor will equal the Dividend. That number is called the Quotient. (Lesson 11.) To find the quotient, there is a method called short division.
