Answer:
The equation of the line normal to the curve of y=cos1/3x, where x=pi is y= 2√3 x - 10.38
Step-by-step explanation:
The equation of the normal to the curve is
Y- y1 = - 1/m (x- x1)
Where m is the gradient.
See attached picture for the complete solution.
<u>Understanding:</u>
The sum of 3 times a number (i'll define it as x) and 4 means
is between -8 and 10 which means the value of 3x+4 is less than 10 and greater than -8. With that said, the inequality for that problem would be
.
<u>Solving the problem:</u>
Now we know that
, you can solve the problem by <em>subtracting 4</em> from each side then<em> dividing by 3.</em>

<u>Final Answer:</u>
<u>
</u>
2/3 x -4 = -2 add 4 to both sides
2/3 x -4 +4 = -2 +4
2/3 x = 2
mutliply both sides by 3/2
(3/2) * (2/3) x = (3/2) * 2
x =3
Answer:
Pair 1: 9 and 3 Pair 2: 3 and 9
Step-by-step explanation:
The difference is 6 and one three times more than the other. Draw a diagram below:
Figure out 1 unit: 6÷2=3
3 = one unit
3 is the first number
Figure out second number: 3+6=9
3 & 9, 9 & 3
So, Pair 1: 9 and 3 Pair 2: 3 and 9
