Let V be the volume of the solid obtained by rotating about the y-axis the region bounded y = 4x and y = x2/4 . Find V by slicin

aliya0001 [1]

Answer:

Step-by-step explanation:

Consider the graphs of the $y = 4x$ and $y = \frac{x^{2} }{4}$ .

By equating the expressions, the intersection points of the graphs can be found and in this way delimit the area that will rotate around the Y axis.

$4x = \frac{x^{2} }{4} \\ x^{2} = 16x \\ x^{2} - 16x = 0 \\ x(x-16) = 0$ then $x=0$ o $x=16$ . Therefore the integration limits are:

$y = 4(0) = 0$ and $y = 4(16) = 64$

The inverse functions are given by:

$x = 2 \sqrt{y}$ and $x = \frac{y}{4}$ . Then

The volume of the solid of revolution is given by:

$\int\limits^{64}_ {0} \, [2\sqrt{y} - \frac{y}{4}]^{2} dy = \int\limits^{64}_ {0} \, [4y - y^{3/2} + \frac{y^{2}}{16} ]\ dy = [2y^{2} - \frac{2}{5}y^{5/2} + \frac{y^{3}}{48} ]\limits^{64}_ {0} = 546.133 u^{2}$

If we get the 100 from number 1 each year for ten years and invest each payment in an account that earns 8% how much will be the

blsea [12.9K]

Answer:

$1,448.66

Step-by-step explanation:

The future value of an annuity with yearly deposits 'P' at an interest rate of 'r' invested for 'n' years is determined by:

$FV = P[\frac{(1+r)^n-1}{r}]$

For P = $100, r = 0.08 and n = 10 years:

$FV = 100[\frac{(1+0.08)^{10}-1}{0.08}]\\FV=\$1,448.66$

The amount at the end of the ten years is $1,448.66

What is the slope that passes through the lines (2.1,-4.2) and (2.5,-5)

Usimov [2.4K]

slope = (y2-y1)/(x2-x1)

= (-5--4.2) /(2.5 -2.1)

(-5+4.2)/(2.5-2.1)

=-.8/.4

m=-2

the slope is -2
