Answer:

D is the correct answer.

Step-by-step explanation:

Distribute (−6x^4 + x^2 − 1)(2x^3 - 4x + 3)

-12x^7 + 24x^5 - 18x^4 + 2x^5 - 4x^3 + 3x^2 - 2x^3 + 4x - 3

Combine Like Terms

-12x^7 + 26x^5 - 18x^4 - 6x^3 + 3x^2 + 4x - 3

Jeremy invests $8, 500 into an account with a 2.4% interest rate that is compounded quarterly. How much money will be in

sertanlavr [38]

Answer:

$9,812.29

Step-by-step explanation:

The amount in Jeremy's account can be computed using the compound interest formula.

<h3>account value</h3>

The formula for the value of an account earning compound interest at annual rate r, compounded n times per year for t years is ...

A = P(1 +r/n)^(nt)

where P is the principal invested.

<h3>formula application</h3>

When P=$8500, r=0.024, n=4, t=6, the formula becomes ...

A = $8500(1 +0.024/4)^(4·6) = $8500(1.006^24) ≈ $9812.29

There will be $9,812.29 in this account after 6 years.

If f(x)=2x and g(x)=x−3, then find f(x)·g(x).

Serhud [2]

Answer:

f(x)g(x) = 2x² - 6x

General Formulas and Concepts:

<u>Algebra I</u>

Expand by FOIL-ing (First, Outside, Inside, Last)

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x

g(x) = x - 3

Substitute: f(x)g(x) = 2x(x - 3)
Distribute 2x: f(x)g(x) = 2x² - 6x

Which equation(s)

GalinKa [24]

Answer: A) y = 7x

<u>Step-by-step explanation:</u>

In order to be a proportional relationship, the equation MUST pass through the origin (0, 0) and only contain two coordinates

A) 0 = 7(0) ---> 0 = 0 TRUE

B) 0 = 2 + 3(0) ---> 0 = 2 False

C) 0 = Vz(0) ---> Too many variables so False

D) 0 = 5 - 0 ---> 0 = 5 False

Triangle DEF with vertices D(2, 6), E(5, 6)and F(5, 1). Write the coordinates of triangle D’E’F’ after a

Yakvenalex [24]

Answer:

The coordinates of triangle after reflection over y-axis

D¹( -2 ,6) , E¹( -5 ,6) , F¹ (-5,1)

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that DEF with vertices D(2,6), E(5,6), and F(5,1)

Given that the triangle DEF reflection over the 'y' - axis then transformed into

( x,y) → (-x,y)

Now,

D(2,6) → D¹( -2 ,6)

E(5,6)→ E¹( -5 ,6)

F(5,1)→ F¹ (-5,1)

<u><em>Final answer:-</em></u>

The coordinates of triangle after reflection over y-axis

D¹( -2 ,6) , E¹( -5 ,6) , F¹ (-5,1)
