Answer:

1/4

Step-by-step explanation:

The equation for the area of a triangle: A = 1/2bh

If all of the dimensions are halved then A = 1/2(1/2*b)(1/2*h) = 1/8bh

1/8bh is 1/4 of 1/2bh.

Solve the quadratic function by completing the square. What are the missing pieces in the steps?
Sergeu [11.5K]

Answer:

x = -2; or x = -8

Step-by-step explanation:

Solve the quadratic function by completing the square. What are the missing pieces in the steps? -32=2(x^2+10)

-32+___=2(x2+10x+25)

18=2(x+5)^2

9=(x+5)^2

+-___=x+5

X=-2 or x=___

Solution:

From the first line:

-32+___=2(x2+10x+25)

Also, in the second line:

18=2(x+5)^2

Let the missing piece on line 2 be a, hence:

x² + 10x + 25 = (x + 5)² and -32 + a = 18

a = 18 + 32 = 50

-32 + 50 =2(x²+10x+25)

18 = 2(x+5)²

Dividing through by 2:

18 / 2= [2(x+5)² / 2]

9 = (x + 5)²

Taking square root of both sides:

√9 = √(x + 5)²

± 3 = x+5

Simplifying the equation to get:

3 = x + 5; -3 = x + 5

x = 3 - 5; or x = -3 - 5

x = -2; or x = -8

Billy found the slope of the line through the points (2,5) and (-2,-5) using the equation
Shkiper50 [21]
Slope is calculated as the change in y over the change in x so you would need to do 5- (-5) which turns the negative sign to a positive making it 5+5=10 and the same thing with the 2s 2-(-2)=4 so the answer would be 10/4 or 5/2. Billy did the reciprocal.

what is the economic and political system in which the government controls property and the distribution of income? in this syst
Nutka1998 [239]

Let's look over the meaning of each option:


Theocracy: Theo- means that it is relating to religion. For example, Theology is the study of religion. This is a system where religious leaders control the country, but it is NOT an economic system.

Monarchy: Monarchy is when there is a king, queen, emperor, etc. It is not an economic system either.

Fundamentalism: A political system that strictly abides by a set of fundamentals. Someone who wants a constitution to be the highest form of law is a fundamentalist. However, this is also not an economic system.

Socialism: WINNER WINNER CHICKEN DINNER! Socialism is a system similar to communism where the government controls the economy and there is communal ownership. This is also the only option which is both a political and economic system.


TL;DR: The answer is Socialism.
