Answer:

4.

a)  4x^4-4x^3-16x^2+16x

b)  4x^4-4x^3-16x^2+16x

5. Yes

Step-by-step explanation:

The distributive property is:

(a+b)(c+d)=ac+ad+bc+bd

It can be extended to a lot of terms as well.

We will use this to multiply both of the probelms shown.

4 a)

(4x^2-4x)(x^2-4)=(4x^2)(x^2)-(4)(4x^2)-(4x)(x^2)+(4x)(4)=4x^4-16x^2-4x^3+16x=4x^4-4x^3-16x^2+16x

The answer is 4x^4-4x^3-16x^2+16x

4 b)

(x^2+x-2)(4x^2-8x)=(x^2)(4x^2)-(8x)(x^2)+(x)(4x^2)-(8x)(x)-(2)(4x^2)+(2)(8x)=4x^4-8x^3+4x^3-8x^2-8x^2+16x=4x^4-4x^3-16x^2+16x

The answer is  4x^4-4x^3-16x^2+16x

5. Yes

The cost of tuition at a college is $12,000 and is increasing at the rate of 6% each year. Use exponential function to find the
Gnesinka [82]

Answer:

The cost of tuition fee after 4 years is $15,149.72.

Step-by-step explanation:

Exponential function:

A=P(1+r)^n

A= the amount after n years

P= Initial amount

r= rate of increasing

n= time in years

The cost of tuition at a college is $12,000. It is increasing at the rate of 6% each year.

Here, P= $12,000, r= 6%= 0.06, n= 4 years.

\therefore A=12,000(1+0.06)^4

\Rightarrow A= 12000(1.06)^4

        =$15,149.72

The cost of tuition fee after 4 years is $15,149.72.

This is the complete list of proper factors of a number<br>what is the number
creativ13 [48]
The factors are all the possible things you would multiply to get the number. So finding the 2 middle numbers, in this case is 21 and 28 and multiplying them, you get 588. If you're not sure if that's right, take the number on the left or right of the 2 middle numbers, 14 and 42. The product of these 2 numbers are also 588. So your number is 588.

The circle below is centered at the point (5 3 ) and has a radius of length 4 what is its equation
sleet_krkn [62]
The equation of the circle is may be expressed as, 
                           (x - h)² + (y - k)² = r²
where h and k are the abscissa and ordinates of its center, respectively, and r is radius. Substituting the given values to the equation above, 
                          (x - 5)² + (y - 3)² = 4²
Simplifying further the equation gives, 
                            x² + y² - 10x - 6y + 18
