how many times larger is 1.9 × 10^-8 is than 4.2 × 10^-13

please help​

Answer:

Linear momentum of an object is the product of the object’s mass and velocity. Linear momentum is a vector quantity, and the direction of momentum is taken to be the direction of the object’s velocity.

or an object with mass  moving at a velocity , the angular momentum  with respect to a reference point is defined using the cross product as:

where  is the position vector of the object that describes the object’s position with respect to the reference point. The units for measuring angular momentum is kg m2 s-1. Since angular momentum is defined in terms of a cross product, the direction of the angular momentum vector is taken to be in a direction perpendicular to both the particle’s position vector  and its velocity vector

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

For this one, you want to solve it similarly to linear equations.

-13x+11<-24x by adding 24x to both sides becomes 11x<11.

From there, you divide by 11 to isolate x, leaving x<1.

Since the equation has a < symbol (not ≤), the dot is not filled in. X is less than 1, so the arrow goes to the left, making it D.

Answer:

Part A:

(2x+7)(5x+9)

(2x*5x)+(2x*9)+(7*5x)+(7*9)

10x^2+18x+35x+63

10x^2+53x+63

Part B:

The polynomial has two terms, so is a binomial; also, the polynomial only has one variable, x, and the largest exponent of that variable is 2; therefore is a degree 2 polynomial. In summary, we have a binomial of degree 2.

Part C: Part A demonstrates the closure property for polynomials because after multiplying the polynomials we obtained another polynomial.

Answer:

-11

Step-by-step explanation:

let (2,1)be x1 and y1 respectively

(3,-10) be x2 and y2 respectively

From,slope= (y2-y1)/(x2-x1)

=(-10-1)/(3-2)

= -11/1

= -11

Answer:

  see below (2nd graph)

Step-by-step explanation:

It can be useful to consider the value of f(4).

  f(4) = 1/2√4 -1 = 1/2(2) -1 = 1 -1 = 0

This matches the 2nd graph best.

Answer:

4.5 is a rational number, as it can be represented as 9/2. Many important numbers in mathematics, however, are irrational, and cannot be written as ratios.

Answer:

1/2

Step-by-step explanation:

y2 - y1 / x2 - x1

-17 - (-8) / -5 - 13

-9 / - 18

= 1/2

Answer:

Step-by-step explanation:

Let ‘x’ be the number

So; the difference of a number and three implies; 3 - x

Therefore, the expression is;

2 (3 - x) or (3 - x) * 2

Answer:

22 units

The correct answer is A

I believe the answer to this is 22 units.

I hope this helps! :D

Answer:

x - 9

Step-by-step explanation:

That should be it, and let me know if I'm wrong. x is by itself and if you were to add 3 and 6 you'd get 9. So x - 9

Answer:

y = 2x+4

Perpendicular lines, when you multiply their gradient, you will get -1. You can also find the negative reciprocal, which is 2. The point (0,4) is the y intercept, which is for. Hence, the equation is y=2x+4

Answer:

84 cm^2

10 cm

Step-by-step explanation:

A parallelogram is  quadrilateral that has two pairs of parallel sides. The opposite sides  equal in length

Area = base x height

12 x 7 = 84 cm^2

Perimeter = 1/2 x ( base + length)

1/2 x (12 + 8) = 10 cm

Answer: X = -7

Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

4 - 2(x - 3) = 24

Distribute

4 -2x +6 = 24

Combine like terms

10 -2x = 24

Subtract 10 from each side

10-2x-10 = 24-10

-2x = 14

Divide by -2

-2x/-2 = 14/-2

x = -7

Answer:

10.3

Step-by-step explanation:

a^2 + b^2 = c^2

3.9^2 + b^2 = 11^2

b^2 = 121 - 15.21

b = 10.3

Answer:

10.3

Step-by-step explanation:

We use the pythagorean theorem. (a^2+b^2=c^2)

3.9^2 + b^2 = 11^2

3.9^2 = 15.21

11^2 = 121

15.21 + b^2 = 121

Subtract 15.21 from both sides

b^2=105.79

Take the square root of both sides

b = 10.28

10.28 is closest to 10.3 and it is also rounded to 10.3, therefore 10.3 is the answer.

Answer:

  (x, y) = (12, -12)

Step-by-step explanation:

The two equations can be added to solve for x.

  (-5x -5y) +(6x +5y) = (0) +(12)

  x = 12 . . . . . . . . simplify

  -5(12) -5(y) = 0 . . . substitute into the first equation

  12 +y = 0 . . . . . . . divide by -5

  y = -12 . . . . . . . . subtract 12

The solution is (x, y) = (12, -12).

Answer:

9 sqrt(2) /2 = PQ

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hypotenuse

sin 45 = PQ = 9

9 sin 45 = PQ

9 sqrt(2) /2 = PQ

Answer:

7.7 cm

Step-by-step explanation:

You need to use trig ratios

this one needs the sin as we been to find the opposite side with the hypontenuse

9 x sin(45) = PQ = 7.65813172081

PQ = 7.7
