The original price of the computer is $600

During the sale, the computer is 15% cheaper. This means that the computer is selling at 85% (100 - 15%) of its original price.

In order to determine the answer to the question, the following information would be needed :

Sales price of the computer = $510
The percentage of the original price the computer is being sold for during the sales = 85%

The formula that can be used to determine the original price of the computer is : sales price / percentage of the original price

$510 / 85%

$510 / 0.85

= $600

What is the fourth term of the binomial expansion for (3x-2y)6

Thepotemich [5.8K]

One way is to just expand it by using binomial theorem
or to use pascal's triangle

ok so

to find the nth term of a binomial, (a-b). where the binomial is to the r power you do
n-1=k

rCk times $(a)^{r-k}(-b)^k$
and rCk= $\frac{r!}{k!(r-k)!}$

so

4th term
4-1=3
6 is exponent

6C3 $(3x)^{6-3}(-2y)^3$ =
$( \frac{6!}{3!(6-3)!} )((3x)^3(-8y^3)$ =
$( \frac{6*5*4}{1*2*3} )(27x^3)(-8y^3)$ =
$(20)(27)(-8)(x^3)(y^3)=-4320x^3y^3$

the 4th term is $-4320x^3y^3$

Can anyone help me out with this?? I dont Understand

The arc length (s) is given in terms of the radius (r) and central angle (θ) by
s = r*θ . . . . . . . where θ is in radians

For your arc, the length is
s = (15 ft)*(π/4) ≈ 11.78 ft

_____
45° can be converted to radians by multiplying by π/180°.
45° * (π/180°) = π*(45/180) = π/4 . . . . radians
