Mike has a barrel in the barn to keep water for his cows. The barrel is 4.5 feet tall and has a diameter of 3 feet. Approximatel

sergiy2304 [10]

Answer:

Approximately $238\ gallons$

Step-by-step explanation:

we know that

The volume of a cylinder (barrel) is equal to

$V=\pi r^{2}h$

in this problem we have

$h=4.5\ ft$

$r=3/2=1.5\ ft$ -----> the radius is half the diameter

substitute

$V=(3.14)(1.5^{2})(4.5)=31.7925\ ft^{3}$

<u>Convert to gallons</u>

$31.7925\ ft^{3}*7.5=238.44\ gallons$

PLEASE HELP, 50 POINTS<br> QUESTION IS IN THE PICTURE

artcher [175]

Answer:

$-\frac{50}{3}$

Step-by-step explanation:

Find dy/dx of the ellipse $25x^{2} +y^{2}=109$ at (2,3)

Using Implicit Differentiation

Differentiate both sides of the equation with respect to x

$25x^{2} +y^{2}=109$

$50x +2y\frac{dy}{dx}=0$

isolate the term dy/dx

$2y\frac{dy}{dx}=-50x$

$\frac{dy}{dx}=-25\frac{x}{y}$

Evaluate at point (2,3)

For x=2, y=3

$\frac{dy}{dx}=-25(\frac{2}{3})$

$\frac{dy}{dx}=-\frac{50}{3}$

Answer:

The answerers are 90"; 45. 45 and 60, 60, 60.

Step-by-step explanation:

The two sides have the same length this would mean that they have the same angle measure on a triangle the only two answers with two of the same angle measures are 90"; 45. 45 and 60, 60, 60 so therefore they are your answers.
