In 2010, the national debt of the United States was about 14 trillion dollars. In 2003 it was about 7 x 10 to the 12 dollars. Ab

maxonik [38]

Okay. 10^12 is 1 trillion. 1 trillion * 7 is 7 trillion. 14 trillion / 7 trillion is 2. The national debt in 2010 is two times larger than in 2003. So that basically means that the national debt doubled from 2003 to 2010.

What is the simplified form of the quantity of x plus 7, all over the quantity of 6 − the quantity of x plus 5, all over the qua

vlabodo [156]

For this case we must simplify the following expression:

$\frac {\frac {x + 7} {6- (x + 5)}} {x + 3}$

We must apply double C:

$\frac {(x + 7) (x + 3)} {6- (x + 5)} =$

We apply distributive property in the numerator:

$\frac {x ^ 2 + 3x + 7x + 21} {6- (x + 5)} =\\\frac {x ^ 2 + 10x + 21} {6- (x + 5)} =$

In the denominator we have by law of signs:

$- * + = -\\\frac {x ^ 2 + 10x + 21} {6-x-5} =$

Different signs are subtracted and the sign of the major is placed:

$\frac {x ^ 2 + 10x + 21} {- x + 1}$

ANswer:

$\frac {x ^ 2 + 10x + 21} {- x + 1}$

5. A rock is tossed from a height of 2 meters at an initial velocity of 30 m/s at an angle of 20° with the ground. Write paramet

Leviafan [203]

Answer:

x = 30t cos 20 or x = 28.19t.

y = 30t sin 20 - 4.9t^2 + 2 or y = -4.9t^2 + 10.26t + 2.

Step-by-step explanation:

The horizontal component of the velocity = 30 cos 20 m/s so the distance at time t seconds = 30t cos 20.

The vertical component is obtained from the equation of motion

s = ut - 1/2* 9.8t^2 + 2

u = 30 sin 20

Vertical component = 30t sin 20 - 4.9t^2 + 2.

For the inequality 4x2>y−3, where is the graph shaded and is the curve solid or dotted?

Alja [10]

Answer:

Dotted Curve

Shaded Area includes the Origin.

Step-by-step explanation:

I am assuming that you mean 4x² > y-3.

Since the inequality sign is greater than, the line would be dotted. The curve would be solid if the inequality was an 'X or equal to' sign.

----------------------------------

4(0)² > 0 - 3

0 > -3

Since the given statement is true, the origin is a solution and we would shade below the curve.

----------------------------------

See the graph attached.

Hope this helps.
