Answer:

i dont have a calculator on me right now

Step-by-step explanation:

put the equations cos(42)=x/18 and sin(42)=y/18 into your calculator and find x and y, then you can figure out the area and perimeter from there

Answer:

The equation of line is shown below.

Step-by-step explanation:

The equation of line is

$y+1=\frac{-3}{5}(x-4)$

It is the point slope form of a line, therefore the slope of the line is $\frac{-3}{5}$ and the line passing through (4,-1).

Rewrite the above equation in slope intercept form.

$y=\frac{-3}{5}x+\frac{12}{5}-1$

$y=\frac{-3}{5}x+\frac{12-5}{5}$

$y=\frac{-3}{5}x+\frac{7}{5}$

The point slope form of a line is

$y=mx+b$

Where m is the slope and b is y-intercept.

Therefore the slope of the line is $\frac{-3}{5}$ and the y-intercept of the line is $\frac{7}{5}$ .

Slope is defined as

$m=\frac{Rise}{Run}$

Since the slope is negative, therefore the run of the line is considered on the left side. The line rise by 3 and run by 5, therefore we will add 7 in y and subtract 5 from x.

The y-intercept is $(0,\frac{7}{5})$ .

$(0-5,\frac{7}{5}+3)=(-5,\frac{22}{5})=(-5,4.4)$

Therefore we have three points (4,-1), (-5,4.4) and (0,1.4). Plot the point on the coordinate plane and connect them be a straight line.

This function <br>Is it differentiable at x = 1 ?

nikklg [1K]

It is not differentiable at x=1 since the slope of the tangent line as x -> 1 from the right is 1 while the slope of the tangent line as x->1 from the left is -1

What are the quadrants of the standard (x,y) coordinate plane below that contain points on the graph of the equation 4x - 2y = 8

miv72 [106K]

Answer: I III and IV

Step-by-step explanation:

The line intersects the x axis at (2,0) and the y axis at (0,-4) so the line goes through quadrants 1 3 and 4 so the answer is the middle or the 3rd from top
