In a laboratory experiment, the population of bacteria in a petri dish started off at 160 and is growing exponentially at 6% per

alexira [117]

The exponential function is given by y = 160(1.06)ˣ

<h3>Exponential function</h3>

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the multiplier, y, x are variables.

Let y represent the amount of bacteria after x hours.

Given an initial 160 bacteria, hence a = 160.

Also b = 100% + 6% = 106% = 1.06

The exponential function is given by y = 160(1.06)ˣ

What is the coeffieent of (x^4)(y^4) in the expansion of (x+y)^8

kap26 [50]

ANSWER

The coefficient is 70.

EXPLANATION

The given binomial expression is

$(x+y)^8$

The specific term of a binomial expansion can be determined using the formula,

$T_{r+1}= nC_ra^{n-r}b^r$
where

$n=8,r=4,a=x,b=y$

We substitute these values into the formula to get,

$T_{4+1}= 8C_4x^{8-4}y^4$

We simplify to get,

$T_{5}= 70x^{4}y^4$

Hence the coefficient is 70.
