Answer:

The y-intercept is 3 aka. (0,3)

Step-by-step explanation:

The slope is 1 (since (6-4)/(3-1)=2/2=1)

y=1x+b

4=1+b

3=b

F(x)=e*1/x<br>Calculate f'(x)

Murljashka [212]

Answer:

$\huge\boxed{f'(x)=-\dfrac{e^\frac{1}{x}}{x^2}}$

Step-by-step explanation:

$(e^x)'=e^x\\\\\bigg[f\bigg(g(x)\bigg)\bigg]'=f'\bigg(g(x)\bigg)\cdot g'(x)\\\\\left(\dfrac{1}{x}\right)'=-\dfrac{1}{x^2}\\\\====================$

$f(x)=e^\frac{1}{x}=\left(e^\frac{1}{x}\right)'\cdot\left(\dfrac{1}{x}\right)'=e^\frac{1}{x}\cdot\left(-\dfrac{1}{x^2}\right)=-\dfrac{e^\frac{1}{x}}{x^2}$

Find the volume of the composite figure below

Marina86 [1]

Answer:

1386 in³

Step-by-step explanation:

Volume of the composite cone = volume of a hemisphere + volume of a cone

=>Find the volume of cone

Volume of cone = ⅓πr²h

π = 3.142

r = 7 in

h = =√(15² - 7²) [using Pythagorean theorem to solve for height given the slant height and radius]

h = √(225 - 49)

h = √176 ≈ 13 in

Volume of cone = ⅓*3.142*7²*13

= ⅓*2001.454 ≈ 667 in³

=>Find volume of hemisphere.

Volume of hemisphere = ½*volume of sphere = ½*4/3πr³ = ⅔πr³

π = 3.142

r = 7 in

Volume = ⅔*3.142*7³ ≈ 719 in³

<em>Volume of composite figure = 667+719 = 1386 in³</em>

What is this equation called?

nadya68 [22]

$\left\{\begin{array}{ccc}3x-6y=20&|\cdot2\\2x-4y=3&|\cdot3\end{array}\right\\\left\{\begin{array}{ccc}6x-12y=40\\6x-12y=9\\\end{array}\right$

The left sides of the equations are the same and the right sides of the equations are different, therefore the system of equations is inconsistent.

Answer: B. inconsistent.

a cylindrical vase has a diameter of 6 inches at the bottom of the vase there are 9 marbles each of diameter 3 inches the vase i

KiRa [710]

Answer:

<h2>The volume of water in the vase is 339.33 in^3</h2>

Step-by-step explanation:

To calculate the volume of water in the vase we need the following parameters

1. the diameter/radius of the vase

2. the height /level of water in the vase

Given data

diameter d= 6 in

radius = d/2= 6/2 = 3 in

height of water h= 12 in

we know that the expression for the volume of a cylinder is given as

$volume= \pi r^2h$

Inserting our data we have

$volume= 3.142*3^2*12\\\volume= 3.142*9*12\\\volume= 339.33 in^3$
