Determine the momentum of a system that consists of two objects. One object, m1, has a mass of 6 kg and a velocity of 13 m/s in the direction of the positive x-axis and a second object, m2, has a mass of 14 kg and a velocity 7 m/s in the direction of the negative x-axis.

Variable x would be easier to solve for.

Step - by - Step Explanation

What to find?

• The value of x.

• The value of y.

• The variable that was easier to solve.

Given:

5x+3y=22

4x-2y=16

Using elimination method,

First solve for x.

To solve for x, multiply through the first equation by 2 and then multiply through the second equation by 3.

10x + 6y = 44 _____________(3)

12x - 6y = 48 ______________(4)

Add (3) and (4)

22x = 92

Divide both-side of the equation by 22

x = 92/22

Reduce the fraction by 2.

x =46 / 11

To solve for y,

Multiply through the first equation by 4 and through the second equation by 5.

20x + 12y = 88 _________________ (5)

20x - 10y = 80 __________________(6)

Subtract equation 6 from 5.

22y= 8

Divide both-side of the equation by 22.

y = 8/22

We can reduce the fraction by 2.

y = 4 / 11

Judging from the steps above, we can deduce that the variable that was easier to solve is x.

Answer: x  of first equation

Step-by-step explanation:

The area is the entire amount of space occupied by a flat (2-D) surface or shape of an object.

The area of the face is 17 in²/17 inches2.

The amount of space occupied by a flat (2-D) surface or an object's shape is known as its area.

Draw a square on a piece of paper using a pencil. A 2-D figure, that is.

The term "Area" refers to the area that a shape occupies on paper.

By squaring the side's length, the area of each face may be calculated.

To determine the overall surface area of the cube, multiply the area of each face by the number of faces.

For big square,

a = 4 in

a*a = 4 * 4 inches

[tex]a^{2}[/tex] = 16 in²

For another small square,

a = 1 in

[tex]a^{2}[/tex] = 1*1 = 1 in²

In total,

[tex]a^{2}[/tex] = 16 + 1 = 17 in²

Therefore, the area of the face is 17 in²

By solving both equations we get x =:

1. x = 12

2. x = 28/3

1. |x - 3| = 2x - 15

|x - 3| - 2x = 2x - 15 - 2x

by simplifying,

- 2x + |x - 3| = -15

- 2x + x -3 = -15  and -2x - (x - 3) = -15

by solving equation ,

= -x -3 = - 15

= -x = -12

x = 12

2. 8 - 2|6 - x|= 20

6 |6 - x| = 20

6 |-x + 6| = 20

dividing both side with 6,

(6 |-x + 6|)/6 = 20/6

| -x + 6| = 10/3

add 6 on both sides,

x - 6 + 6 = 10/3 +6

x = 28/3

Congruent polygons are those that have equal measurements. Since we are given their graphs, we simply inspect each pair of polygons to determine which among them are congruent.

I have made an example using the first pair. I rotated the first polygon (the red one) to show that they are indeed congruent.

Following the same process, we can see that pairs 3 and 4 are also congruent.

Pair 2 are not congruent because the green rectangleis longer.

The binomial formula with the given parameters has a value of 0.0272

The given parameters are

N = 65

p = 0.5

X = 39

The interpretation of the above parameters are

Sample size, N = 65

Probability of success, p = 0.5

Number of success, X = 39

The binomial probability states that

P(x) = ⁿCₓ * pˣ * (1 - p)ⁿ⁻ˣ

Where n, p and x are the same as the parameters described above

When the values are substituted in the binomial probability formula, we have

P(39) = ⁶⁵C₃₉ * (0.5)³⁹ * (1 - 0.5)⁶⁵⁻³⁹

Evaluate the difference

P(39) = ⁶⁵C₃₉ * (0.5)³⁹ * (0.5)²⁶

Evaluate the products

P(39) = ⁶⁵C₃₉ * (0.5)⁶⁵

This gives

P(39) = 0.0272

Hence, the value of the binomial formula is 0.0272

The resulting exponent form is, 1/9¹⁰

Exponent:

Exponent is used to show repeated multiplication of a number by itself. For example,

7 × 7 × 7 can be represented as 7³

Here, the exponent is ‘3’ which stands for the number of times the number 7 is multiplied.

Given,

Here we have the exponent form is,

9⁻⁸x9⁻²

Here we have to use the product property and then we have to get rid of negative exponents.

First step is to use the product property,

We know that, the product property states that,

for any non-zero term a,

yᵃ x yᵇ = yᵃ⁺ᵇ

where a and b are real numbers.

So, the given expression is written as,

=> 9⁻⁸⁺⁽⁻²⁾

=> 9⁻⁸⁻²

=> 9⁻¹⁰

Now the second step is to get rid of the negative components,

As per the rule, the exponent is negative, we can change the exponent into positive by writing the same value in the denominator and the numerator holds the value 1.

So, the value is,

Car B travelled with the rate of speed of 40mph .

In the question ,

it is given that ,

Car B travelled 5mph slower than Car A .

let the rate of speed at which Car B travelled be x mph.

So , the rate of speed of Car A is = (x+5) mph

Car A travelled the distance in 4 h , with the speed of (x+5) mph ,

the value of T = 4 h and R = (x+5) mph

So, by the formula R*T=D ,

we get ,the distance travelled by Car A = 4(x+5) miles .

Car B travelled the distance in 4.5 h , with the speed of x mph .

the value of T= 4.5h  and R = x mph

So, by the formula R*T=D,

we get , the distance travelled by Car B = 4.5*x = (4.5x) miles .

Since , both the cars travelled the equal distance ,

we get ,

4(x+5) = 4.5x

4x+20=4.5x

The $7,000 worth of purchase and payment of $5,000 before the three months deadline gives the amount owed at 2.49% monthly compound interest rate as $2,153.15

Owed: $2,153.15

Compound interest accounts for the interest that is earned on an interest, such that the interest rate is compounded on an initial amount.

The given parameters are;

The amount of the items purchased from the store = $7,000

The amount of down payment required = 10%

The amount paid in three months = $5,000

Monthly interest on amount owed after three months = 2.49%

Required;

The amount owed after payment of $5,000 before three months

Solution;

Using the compound interest formula, we have;

[tex] \displaystyle{A = P \cdot \left(1 + r \right)^{n} }[/tex]

Where;

A = The amount owed

P = The amount loaned = $7,000 - $5,000 = $2,000

r = Monthly interest rate = 2.49%

n = The number of months = 3 months

As given in the question,

The revenue for selling x units of a product is R = 113.95 x.

The cost of producing x units is C = 93 x + 750

To make a profit, the revenue must be greater than the cost.

R > C

113.95x > 93x +750

Subtract 93x from both the sides

To find the y =?

Now, According to the question:

Because the graph of a quadratic goes through point (-8 ,0) and point   (2, 0)

So, supposing the equation of the quadratic function is  

y = a [x - (-8)] (x - 2) = a (x + 8)(x - 2)

The graph passes through the point (-6, 16)

So, -16 = a(-6 + 8)(-6 -2)

=> -16 = a x 2 x (-8)

=> a = 1

So, y = (x + 18)(x - 2)

y = [tex]x^{2}[/tex] + 8x - 2x - 16

y = [tex]x^{2}[/tex] + 6x - 16
