Answer:

Below.

Step-by-step explanation:

SinA×tanA/1-CosA

As tanA = sinA / cos A we have

sin^2A / cosA(1 - cosA)

= (1 - cos^2A) / cosA(1 - cosA)

= (1 - cosA)(1 + cosA) / cosA(1 - cosA)

= (1 + cosA) /cos A

= 1 + 1/cosA

= 1 + secA.

If point A(-5, 2) is rotated 90 degrees clockwise about the origin, what will be the coordinates of the point in its new positio

Anettt [7]

Answer:

(2,5)

Step-by-step explanation:

Keep in mind that clockwise is towards the right in this problem. We are moving the point from quadrant 2 to quadrant 1.

Draw a picture for yourself to help this make sense. Put the point, then just turn your whole paper 90 degrees to the right. This is your new point!

The area of a rectangle is 5/8 meter. The length of the garden is 1/5 meter. What is the width of the rectangle?

Afina-wow [57]

Width of rectangle is $Width=\frac{25}{8} meters$

Step-by-step explanation:

Area of rectangle = $\frac{5}{8}$

Length of garden = $\frac{1}{5}$

Width of rectangle = ?

Using the Formula:

Area = Length * Width

Putting values and finding width:

$\frac{5}{8}=\frac{1}{5}*Width\\ Width=\frac{5}{8}\div\frac{1}{5}\\Width=\frac{5}{8}*\frac{5}{1}\\Width=\frac{25}{8} meters$

So, width of rectangle is $Width=\frac{25}{8} meters$
