Given f(x) = −9x5 − x4 + 3x3 − 8 and g(x) = −9x5 − 3x3 − 9x2 + 7, find and simplify f(x) − g(x)

KatRina [158]

F(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 − (<span>−9x^5 − 3x^3 − 9x^2 + 7)
</span>f(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 + 9x^5 + 3x^3 + 9x^2 − 7
f(x) − g(x) = − x^4 + 6x^3 +  9x^2 - 15

The population of a town increased from 3450 in 2006 to 4650 in 2011. Find the absolute and relative (percent) increase.

netineya [11]

Answer:

15% increase per year.

Step-by-step explanation:

5,600 - 3,500 = 2,100

2,100 is what percent of 3,500?

2,100 = X*3,500

X = 2,100 / 3,500

X = .60 or 60%

An average of 15% increase per year.

Simplify the expression. 12x^-6 y^10 times 3x^7 y

Vlada [557]

We need to simplify the expression:

$12x^{-6}y^{10} \times (3x^{7}y)$

Now, we know that we can resolve the exponents of the variables with the like terms only and we can multiply the coefficients independently:

Now,

$12x^{-6}y^{10} \times 3x^{7}y=(12 \times 3)\times (x^{-6}\times x^{7})\times (y^{10}\times y)$

On simplifying the above expression we get:

$36\times x^{(-6+7)}\times y^{(10+1)}$

$=36 \times x^{1}\times y^{11}$

$=36 \times x \times y^{11}$

$=36xy^{11}$

So the simplified form of the expression $12x^{-6}y^{10} \times 3x^{7}y=36xy^{11}$ .
