Combine and write in standard form. 2x(3x2 + 8x – 4) – 3(2x2 + x – 5)

beks73 [17]

Answer:

6x^3 +10x^2 -11x +15

Step-by-step explanation:

2x(3x2 + 8x – 4) – 3(2x2 + x – 5)

Distribute

6x^3 + 16x^2-8x -6x^2 -3x+15

Combine like terms

6x^3 + 16x^2 -6x^2 -3x-8x+15

6x^3 +10x^2 -11x +15

Standard form is from highest to lowest power

6x^3 +10x^2 -11x +15

A fireworks company has two types of rockets called Zinger 1 and Zinger 2. The polynomial -16t^2+150t gives the height in feet o

Alisiya [41]

The height of Zinger 1 after 6 seconds is given by the polynomial

$-16 t^{2}+150t$ , for t = 6,

so the height is $-16 *6^{2}+150*6=-576+900=324$ (feet)

The height of Zinger 2 after 6 seconds is given by the polynomial

$-16 t^{2}+165t$ , for t = 6,

so the height is $-16 *6^{2}+165*6=-576+990=414$ (feet)

At the moment the rockets explode, Zinger 2 is 414-324=90 (feet)

higher than Zinger 1.

Answer: 90 feet

This is a geometric sequence because each term is a constant multiple, called the common ratio, of the previous term. In this case the common ratio, noted as "r", is:

8/-2=-32/8=128/-32=r=-4

The first term is -2

Any geometric sequence can be expressed as:

a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.

Since we know r and a for this problem already we can say:

a(n)=-2(-4)^(n-1)

Answer:

x=1/2 y =1

Step-by-step explanation:

(-4x+2y)/2x5=0/2x5

10x+3y=8

(-2x+y)x5=0

10x+3y=8

-10x+5y=0

10x+3y=8

8y=8

y=1

x=1/2
