What is the result if you divide –12x8y8 by 3x4y2?a. 4x4y6
b. 4x2y4
c. –4x2y4
d. –4x4y6

Answers

When dividing two numbers with the same base but with different powers, you subtract the second power from the first and keep the base. So in our case, -12*x^8*y^8 / 3*x^4*y^2 = -4*x^4*y^6. The correct answer is d.

Answer:

option d is correct

$-4x^4y^6$

Step-by-step explanation:

Using exponent rules:

$(a^n)/(a^m) = a^(n-m)$

Given that:

If you divide $-12x^8y^8$ by $3x^4y^2$

⇒ $(-12x^8y^8)/(3x^4y^2)$

⇒ $(-4x^8y^8)/(x^4y^2)$

Using exponent rules, we have;

⇒ $-4x^(8-4)y^(8-2)$

⇒ $-4x^4y^6$

Therefore, If you divide $-12x^8y^8$ by $3x^4y^2$ we get; $-4x^4y^6$

You have $28.49. You spend $14.95 at a bowling alley. You win $35.00 for setting the record score for your age group. How much money do you have now?

Using coal, steam, and _____, the fischer-tropsch procedure converts coal into a liquid fuel.

Answers

Answer:

Using coal, steam, and OXYGEN, the fischer-tropsch procedure converts coal into a liquid fuel.

Step-by-step explanation:

A series of chemical reactions in which hydrogen and carbon monoxide converges into liquid hydrocarbons by using a metal catalyst. This process is called The Fischer-Tropsch process.

Converting Coal into Liquid Fuel is know as Coal liquification.

IN Liquification process Oxygen, heat is used.

Therefore steam is for heat and oxygen to covert coal into liquid fuel.

A ball is launched from a sling shot. Its height, h(x), can be represented by a quadratic function in terms of time, x, in seconds.After 1 second, the ball is 148 feet in the air; after 2 seconds, it is 272 feet in the air.

Find the height, in feet, of the ball after 6 seconds in the air.

I have no idea any help?

Answers

From the data given, generate first the quadratic equation which best describe the height of the ball. The quadratic function has a general form of
f(x) = Ax^2 + Bx

Substituting the known data,

(1) 148 = A(1^2) + B(1)
(2) 272 = A (2^2) + B (2)
solving for A and B simultaneously,

A = -12
B = 160

To answer this problem, substitute 6 to x. Thus, after 6 seconds, the height is 528 feet.
