Answer:

The answer is option A

A) Circumference= 12 $\pi$ m

Step-by-step explanation:

To find the circumference of a circle the formula you would use is C=2 $\pi$ r

if the radius is 6 meters, C is

C = 2*6 $\pi$ r

C= 12 $\pi$ m

PLEASE help me...Suck at math. find the following using the given triangle.

Ulleksa [173]

To find the perimeter just add the sides

5+5+6 = 16

To find the area, you need to use the following formula

$area = \frac{1}{2}bh$
we know b but we need to find the height. We can find the heigh by using pythagorean theorem $a^2 + b^2 = c^2$

height = $a^2 + 3^2 = 5^2$
$a^2 + 9 = 25$
$a^2 = 25 - 9$
$a^2 = 16$
$a = \sqrt{16} = 4$
h = height = 4

$area = \frac{1}{2}\times 6\times 4 = 12cm^2$

Cost:

6.00 per cm^2 = 6.00 x 12 = $72.00 dollars

What is the slope of the line?

Talja [164]

Answer:

Step-by-step explanation:

The line intersects at (0, -3) and (2, 1). Slope is m. $m= \frac{y2 - y1}{x2 - x1}$

Sub your values in. $\frac{1--3}{2-0} or \frac{4}{2} or \frac{2}{1}$

Your slope is 2.

A new DVD is available for sale in a store one week after its release. The cumulative revenue, $R, from sales of the DVD in this

AnnyKZ [126]

Solution :

It is given that :

$f'(t) = (350 \ln t)'$

$=350(\ln t)'$

$=\frac{350}{t}$

So, $f(5)=350 \ln (5) \approx 563$

$f'(5) = \frac{350}{5}$

$=70$

The relative change is then,

$\frac{f'(5)}{f(5)}=\frac{70}{350\ \ln(5)}$

$=\frac{1}{5\ \ln(5)}$

$\approx 0.12$

$=12\%$

This means that after 5 weeks, the revenue from the DVD sales in $563 with a rate of change of $70 per week and the increasing at a continuous rate of 12% per week.

An athletic field is a 48 yd-by-96 yd rectangle, with a semicircle at each of the short sides. A running track 20 yd wide surr

MA_775_DIABLO [31]

The distance would be equal to 2 times the longest side of the rectangle plus twice the shortest side multiplied by pi / 2 for the semicircle, that is:

longest side 96 and shortest 48

D = 2 * (96) + 2 * (1/2) * pi * 48

D = 192 + pi * 48

This shorter side, which starts at 48, will expand each time by two more in proportion to 20 of the running track between 8 than the number of divisions, that is, 2 * (20/8) = 5

In other words, there are 8 distances, like this:

D1 = 192 + 3.14 * 48 = 342.72 yd

D2 = 192 + 3.14 * (48 + 5) = 358.42 yd

D3 = 192 + 3.14 * (48 + 10) = 374.12 yd

D4 = 192 + 3.14 * (48 + 15) = 389.82 yd

D5 = 192 + 3.14 * (48 + 20) = 405.52 yd

D6 = 192 + 3.14 * (48 + 25) = 421.22 yd

D7 = 192 + 3.14 * (48 + 30) = 436.92 yd

D8 = 192 + 3.14 * (48 + 35) = 452.62 yd
