1 answer:
Eddi Din [679]3 years ago
7 0

Answer:

37 units

Step-by-step explanation:

The horizontal distance between these two points is 35 and the vertical is 12.

Treat these distances as the lengths of the legs of a right triangle whose hypotenuse we want to determine:

d^2 = 35^2 + 12^2 = 1369, so d  = the distance between these two points = d = sqrt(1369) = 37 units

Indefinate integral of sin-1(x? i know you have to use integral by parts: u = sin-1(x v = x
svet-max [94.6K]
Yes 
you let u = sin-1 x and dv = 1 ( so v = x)
and use the rule
 INT udv    =  uv - INT vdu
                  = x sin^-1 x  - INT x sin-1 x

u = sin-1 x  so x = sin u 
dx/du = cos u  , du/dx = 1 / cos u  = 1 /  sqrt(1 - sin^2)  = 1 / sqrt (1-x)^2
so substituting we have 

INT sin-1(x)  = x sin-1x  - INT ( x / sqrt(1- x^2)
                      = x sun-1 x - ( - sqrt (1 - x^2)
                      =  x sin-1 x + sqrt(1 - x^2) + C

Living room furniture with a cash price of $2900 at $100 down and $89.5 per month for 36 months
worty [1.4K]

Answer:

$3222 in total; $322 more than the original price.

Step-by-step explanation:

For 36 months you pay a total of 36* 89.5=3222.0

Downpayment was 100

Total payment made= 3222+100=3322.

You would pay 3222-2900=$322 higher than normal.

Find the value of n
Hitman42 [59]
There are 6 sides so that means that the angles add to 180(6-2) = 180(4) = 720 degrees

So let's add up the angles and set that result equal to 720. Then solve for n

Note: I'm starting at the angle n and working counter-clockwise

(n)+(140)+(151)+(62)+(135)+(n+6) = 720
n+140+151+62+135+n+6 = 720
2n+494 = 720
2n+494-494 = 720<span>-494
</span>2n = 226
2n/2 = 226/2
n = 113

So the final answer is n = 113
