Answer:

Step-by-step explanation:

1) \frac{tan A + Sin A}{tan A - Sin A}=\frac{\frac{sin A}{cos A}+sinA}{\frac{sinA}{cos A}-sin A}\\\\=\frac{\frac{sin A + Sin A CosA}{Cos A}}{\frac{sinA-sinAcosA}{cosA}}\\\\=\frac{sin A + Sin A CosA}{Cos A}*\frac{cosA}{sinA-sinAcosA}\\\\=\frac{sinA+sinAcosA}{sinA-sinAcosA}\\\\=\frac{sinA(1+cosA)}{SinA(1-cosA)}\\\\\frac{1+cosA}{1-cosA}\\\\=\frac{1+\frac{1}{secA}}{1-\frac{1}{secA}}\\\\=\frac{\frac{secA+1}{secA}}{\frac{secA-1}{secA}}\\\\=\frac{secA+1}{secA-1}

The endpoints of CD are C(–8, 4) and D(6, –6). What are the coordinates of point P on CD such that P is the length of the line s
Arturiano [62]
If you graph the end points C and D then graph the 4 points at the end it is difficult to tell which points are on CD without a line.  
Using the endpoints find the slope (change in y/ change in x) then substitute a point in to find the intercept.  
Slope = (-6-4)/(6- -8) = -5/7
Intercept equation (-6) = -5/7 (6) + b
b = -1.71428571429
Graphing the line shows only 2 points on the line (–2.75, 0.25) and <span>(0.75, –2.25)
I am confused by the part, "</span><span>P is the length of the line segment from D".  Were you given a length P to help you determine which point.  Using the distance formula to find the length from each point to D doesn't help determine which one is best with the information you have given.  The image shows the distances I calculated and the graphed points. 
I hope this helps!</span>

How do you solve the inequality of -11.3 is equal to or greater than -4.7 + 4x​
DerKrebs [107]

Answer:  -1.65 ≥ x

Step-by-step explanation:

We usually express "equal to or greater than" by using the symbol ≥.

And we set up the inequality by looking at the word description, then we have:

-11.3 ≥ -4.7 + 4x            plus 4.7 on both sides.

-6.6 ≥ 4x                      divide 4 on both sides.

-1.65 ≥ x

What is the answer to this problem
Elden [556K]
I think when you have a fraction like that, you multiply the denominator on both sides obviously by the first step

1 - 3x/5 = -7

Multiply on both sides
1 - 3x/5 * 5 = -7 * 5

and Solve
1 - 3x = -35

Subtract 1 from both sides of the equation
-3x = -36

Divide both sides by -3
-3x / -3 = -36 / -3 (← answer)
x = 12

Hope it helps
