What will be the value of the 22nd coefficient of a binomial raised to the power 25​
Alona [7]

Step-by-step answer:

We are looking at the coefficient of the 22nd term of (x+y)^25.

Following the sequence, first term is x^0y^25, second term is x^1y^24, third term is x^2y^23...and so on,  22nd term is x^21y^4.

The twenty-second term of (x+y)^25 is given by the binomial theorem as

( 25!/(21!4!) ) x^21*y^4

=25*24*23*22/4! x^21y^4

= 12650 x^21 y^4

The coefficient required is therefore 12650, for a binomial with unit valued coefficients.

For other binomials, substitute the values for x and y and expand accordingly.

Question would have been more clearly stated if the actual binomial was given, as commented above.

100 points Help my grades depend on this
ipn [44]
She earned 1149, which is between 436 and 1506 so you would use the 2nd row for the information.

the tax rate says 15% for the amount over 436
 so fist find the amount that is taxable:

1149 - 436 = 713
 now multiply that amount by 0.15 ( 15% as a decimal)

713 * 0.15 = 106.95

now add the base tax to that amount for the total amount of tax:  
106.95 + 34.90 = 141.85 total tax withheld

What is the standard form equation of the line shown below?
jolli1 [7]
(-1,5)(2,4)
slope = (4 - 5) / (2 - (-1) = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points (2,4)...x = 2 and y = 4
now sub and find b, the y int
4 = -1/3(2) + b
4 = -2/3 + b
4 + 2/3 = b
12/3 + 2/3 = b
14/3 = b

so ur equation is : y = -1/3x + 14/3....however, this is not ur answer because it is not in standard form.

y = -1/3x + 14/3
1/3x + y = 14/3....multiply both sides by 3
x + 3y = 14 <=== standard form
