What is the equation of this line?
y=34x−3
y=−3x−34
y=−3x−43
y=43x−3
Answers
Step-by-step explanation:
this line goes through the points (0, -3) and (4, 0).
so, the y-axis intercept is at y = -3.
therefore, the equation has to end with "- 3".
the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :
x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).
so, the slope is 3/4.
and so, the equation is
y = (3/4)x - 3

[tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Hi there!
We are given the following expression:
[tex]\frac{1}{6}[/tex] ÷[tex]\frac{1}{5}[/tex]
And we would like to solve it
Whenever we are dividing fractions, we are actually multiplying the first fraction (in this case, 1/6) by the reciprocal of the second fraction (in this case, 1/5), which is the "flipped" version of that fraction; the value that is in the numerator becomes the value in the denominator, and the value in the denominator becomes the value in the numerator.
So the reciprocal of 1/5 is 5/1, or 5/1
So we will multiply 1/6 by 5
[tex]\frac{1}{6} * 5 = \frac{5}{6}[/tex]
The fraction is in the simplest form; 5/6 is the answer.
Hope this helps!
When dividing fractions we keep the first fraction the same , change the sign to multiplication and flip second fraction. Some teachers use KCF (keep change flip) as a way for students to remember .
So let’s do it :
1/6 x 5/1 = 5/6
Your answer is 5/6

Answer:
y=-x+pi/3+sqrt(3)/2
Step-by-step explanation:
*I assume you are asking for help on part a because the other question is a calculator question.*
We want to find tangent line to y=2sin(x)cos(x) at x=pi/3.
First I prefer to use y=sin(2x). (Double angle identity: sin(2x)=2sin(x)cos(x) .)
Differentiate using chain rule:
y'=2cos(2x)
y' gives us the slope for any tangent along our curve.
So at x=pi/3, the slope is 2cos(2×pi/3)=2cos(2pi/3)=2(-1/2)=-1.
We also need to know a point our line to find the equation of our line.
At x=pi/3, y=sin(2×pi/3)=sin(2pi/3)=sqrt(3)/2.
So a point on our line is (pi/3, sqrt(3)/2).
So by point-slope form of a line we have
y-y1=m(x-x1)
y-sqrt(3)/2=-1(x-pi/3)
Distribute:
y-sqrt(3)/2=-x+pi/3
Add sqrt(3)/2 on both sides:
y=-x+pi/3+sqrt(3)/2
Answer:
y= -x+(pi/3)+(sqrt3)/2
Step-by-step explanation:
The given is y=2sin(x)*cos(x)
to take the derivative we will need to use the constant rule (which says when taking the derivative of any constant multiplied by an expression you take the derivative of the function and multiply it by the constant) and the multiplication rule to get
y'=2(sin(x)*-sin(x)+cos(x)*cos(x))
this would simplify to be
y'=-2sin^2(x)+2cos^2(x)
We then substitute in the given x value to find the slope of the tangent line at that point and get
-2sin^2(pi/3)+2cos^2(pi/3)
which simplifies to
-2*3/4+2*1/4
which is -1
Since we have the slope we need to find the y value to go with the original x so that we have a point to use in point slope form. When we substitute pi/3 into the given equation we get (sqrt 3)/2 and have the point (pi/3, sqrt3/2)
now we write the point slope form equation
y-(sqrt3)/2= -(x-pi/3)
y-(sqrt 3)/2 = -x+pi/3
y= -x+pi/3+(sqrt3)/2
you could simplify the last two terms, but I think it is simplest to understand this way.

Ice on a lake gets thicker as long as the temperature is below freezing. On a certain lake it took 8 days for the ice to reach a thickness of 3 inches. At what rate was the ice growing over these 8 days in inches per day?
Answers
The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth
The growth rate of the ice over the 8 days is 0.375 inches/day
Reason:
The known information on the ice are;
The time it took the ice to reach a thickness of 3 inches = 8 days
Required:
The (average) rate that the ice is growing in c=inches per day
Solution:
[tex]Rate \ of \ growth \ of \ ice= \dfrac{Increase \ in \ thickness}{ Time} = \dfrac{\Delta \ Thickness}{\Delta T}[/tex]
Therefore;
[tex]Rate \ of \ growth \ of \ ice= \dfrac{3 \ inches}{ 8 \ days} = 0.375 \ inches/day[/tex]

If l| m, find the values of x and y in the diagram below
Answers
Answer: x= 13, y=24
Step-by-step explanation:
7x - 31 + 63 + 5x - 8 = 180 (sum of co-interior angles)
Solving this we get x = 13
4y + 27 + 5x - 8 = 180 (sum of co-interior angles)
Replacing x=13 and solving, we get y = 24
The value of x is 7 and y is 31.5.
What is Transversal line?Transversal line is a line that is formed by cutting two or more parallel lines.
Here there are two transversal lines which cut two parallel lines.
If two parallel lines are cut by a transversal line, then the interior angles on the same side of the transversal will be supplementary.
The angles of measures (7x - 31)° and (5x - 8)° + 63 are two interior angles on the same side of transversal and are thus supplementary.
(7x - 31)° + (5x - 8)° + 63 = 180°
7x + 5x - 31 - 8 + 63 = 180
12x + 24 = 180
12x = 180 - 24
12x = 156
x = 156/12 = 13
Similarly, (5x - 8)° and (4y + 27)° are a pair of interior angles on the same side of transversal.
(5x - 8)° + (4y + 27)° = 180°
5x + 4y + 19 = 180
(5 × 13) + 4y + 19 = 180
65 + 4y + 19 = 180
4y = 96
y = 24
Hence the values of x and y are 13 and 24 respectively.
