What is the geometric mean of 40 and 15?

You would do 40/x=x/15, therefore you get x^2=600. to find x you find the square root of each side. Rounded to the nearest tenth, you get 24.5. If you put it in simplest radical form you should get 10 times the square root of 6

WILL MARK BRAINLEST PLS HELP
Rudiy27

Answer:

None

Step-by-step explanation:

The center of the ellipse is at  (2,  4)

The length of the x axis is  a=  (8-2) =6

The length of the y axis is b=(16-4) = 12

The formula for an ellipse is

(x-h) ^2       (y-k)^2

----------- + -------------- = 1^2

a^2              b^2

where (h,k) is the center

and a and b are the  lengths of the major and minor axes

(x-2) ^2       (y-4)^2

----------- + -------------- = 1

6^2              12^2

 none of your choices have b>a  and for the ellipse to be vertical b>a

How would you set up this problem to find the height of the sail using reciprocal functions?
AVprozaik [17]

Remark

I'm not sure I know what you mean, but I will answer trying to interpret it so it fits the description of the question.

Step One: Set up the equation. The normal way of solving this would be to use the Cos function.

Cos(theta) = Adjacent / hypotenuse = x/8 Multiply both sides by 8

8*cos(theta) = x Theta = 35

8*cos(35) = x This is about as simple a way as is possible.

6.553 = the height of the sale.

Step Three: try using the reciprocal

1 / cos(35)= hypotenuse / adjacent

1/0.8191 = 8/x cross multiply

x = 0.8191 * 8

x = 6.553
